These spiral sweet potatoes are roasted in a cast iron skillet with garlic, rosemary, and a little brown sugar. The slices are shingled in a shallow spiral, so each one shows an exposed top edge that can brown in the oven. Soft centers, browned edges, and a caramel note from the sugar are the goal.

Roasted spiral sweet potatoes work as a side dish for a holiday table or a weeknight dinner. The recipe uses a 10½- to 11-inch ovenproof dish and serves 6.

Test the potatoes before the second stage of baking. The overlapping slices should be nearly tender by then. That leaves enough oven time for the tops to brown while the thicker layers finish underneath.

For a different way to roast sweet potatoes, try my Parmesan-crusted sweet potatoes, which have a buttery, golden cheese crust.

Servings: 6 as a side dish
Prep time: 20 minutes
Cook time: 50–65 minutes
Total time: 1 hour 10 minutes–1 hour 25 minutes
Equipment: 10½- to 11-inch (27–28 cm) ovenproof skillet, preferably cast iron

Ingredients

• 2¾ pounds (1.25 kg) orange-fleshed sweet potatoes, weighed before peeling; about 2¼ pounds (1 kg) after peeling and trimming

• 3 tablespoons (42 g) unsalted butter, melted

• 1 tablespoon packed light brown sugar (13 g)

• 2 tablespoons (30 ml) olive oil, divided, plus about 1 teaspoon for greasing the skillet

• 3 medium garlic cloves, finely grated

• 2 teaspoons finely chopped fresh rosemary

• 1 teaspoon fine sea salt

• ¼ teaspoon freshly ground black pepper

• ½ teaspoon finely grated lemon zest, optional, for serving

• A small pinch of flaky sea salt, optional, for serving

Instructions

1. Set a rack in the middle of the oven. Heat to 350°F (180°C) for a conventional oven, or 320°F (160°C) for a fan oven. Brush the bottom and sides of the skillet with the extra teaspoon of olive oil.

2. Peel the sweet potatoes, trim the ends, and slice crosswise into rounds about ⅛ inch (3 mm) thick. A mandoline gives consistent slices; use its hand guard. Keep the smaller rounds for the center of the skillet.

3. In a large bowl, stir the brown sugar into the warm melted butter. Mix in 1 tablespoon of the measured olive oil, the garlic, the rosemary, the salt, and the pepper. Add the potato slices and turn them gently through the mixture. Separate any slices that stick together so both sides get coated.

4. Start against the outside wall of the skillet and overlap the slices around the edge, leaning them at a shallow angle. Continue with smaller rings toward the center. Keep the upper edges visible and leave enough room to nudge the slices apart rather than compressing them into a tight stack. Scrape any seasoning left in the bowl over the potatoes.

5. Seal the skillet tightly with foil and bake for 30 minutes. Carefully lift the foil and push a thin knife through several overlapping slices near the center. It should enter with only slight resistance. If the potatoes still feel firm, reseal the foil and bake for another 5–10 minutes before checking again.

6. Remove the foil and brush the tops with the remaining 1 tablespoon olive oil. Increase the oven to 425°F (220°C) conventional, or 400°F (200°C) fan, and return the uncovered skillet to the oven. Bake for approximately 20–25 minutes. Check the color after 15 minutes, since the brown sugar can darken quickly. Rotate the pan if one side browns faster. The potatoes are ready when the exposed edges are golden to deep brown and a knife slides easily through the center.

7. Add the lemon zest, if using, and taste before adding any flaky salt. Serve promptly, scooping down through the layers to include both the browned tops and the soft potatoes underneath.

Tips for Tender Layers and Browned Edges

The rounds can differ in diameter, but keep the thickness consistent. Thicker slices need more time to soften. Tuck smaller rounds into gaps without building a thick mound in the middle.

A shallow, overlapping arrangement gives the oven more surface to brown. Avoid squeezing the slices tightly together.

The brown sugar encourages browning, so watch the color during the final bake. If the tops become dark while the lower layers are still firm, cover the skillet again, reduce the oven to the first-stage temperature, and continue baking until tender.

For dried rosemary, use ⅔ teaspoon in place of the fresh, crushing it between your fingers before adding it to the butter.

The optional lemon zest adds a fresh citrus note that works well with the butter and rosemary. Sprinkle it on after baking.

What to Serve With It

Serve the skillet with roast chicken, turkey, or air fryer pork tenderloin. Green beans or a salad with a sharp vinaigrette go well alongside the sweet potatoes.

Storage and Reheating

Transfer leftovers to a shallow container and refrigerate within 2 hours, or within 1 hour if the temperature is above 90°F (32°C). Keep refrigerated at 40°F (4°C) or below and use within 3–4 days. 

Reheat portions in a shallow, lightly oiled baking dish at 350°F (180°C) until they reach 165°F (74°C) throughout. Start checking after 10 minutes. The edges soften during storage, though oven reheating can restore some browning.

This french toast casserole recipe starts the night before, when cubed day-old bread soaks in a custard of eggs, whole milk, and a little heavy cream. In the morning you scatter a brown sugar streusel over the top and bake it until the edges caramelize and the center sets. The work happens ahead of time, so breakfast is just a matter of sliding the dish into a hot oven, which is why it earns a spot on holiday mornings when the stove is already crowded.

Let the bread soak for at least 30 minutes if you’re pressed for time, though overnight gives the firmest, most custardy result. Round out the table with crisp apple cider donuts and biscuits and gravy, and no one reaches for a second plate.

Ingredients

• 1 lb (about 1 loaf) day-old French bread or brioche, cut into 1-inch cubes
• 8 large eggs
• 2 cups whole milk
• ½ cup heavy cream
• ½ cup granulated sugar
• ¼ cup packed light brown sugar
• 2 teaspoons vanilla extract
• 1 ½ teaspoons ground cinnamon, divided
• ¼ teaspoon fine salt
• 3 tablespoons unsalted butter, softened, for the dish
• ½ cup all-purpose flour
• ½ cup packed light brown sugar
• 1 teaspoon ground cinnamon
• ¼ teaspoon fine salt
• ½ cup cold unsalted butter, cut into small pieces
• ½ cup chopped pecans or walnuts (optional)
• Maple syrup, powdered sugar, and fresh berries, for serving

Instructions

1. Dry and cube the bread: Cut the bread into 1-inch cubes and spread them on a sheet pan to dry for at least 30 minutes, or leave them out overnight. Stale, dry bread is what soaks up the custard without collapsing into paste, while fresh soft bread turns the middle gluey. If your bread is still soft, toast the cubes at 300°F for 8 to 10 minutes and let them cool.
2. Butter the dish: Grease a 9×13-inch baking dish with the softened butter, getting the corners and about an inch up the sides. That thin layer keeps the custard from sticking and lets the bottom of the casserole caramelize a little as it bakes. Spread the bread cubes evenly in the dish and press them down into a single loose layer.
3. Whisk the custard: In a large bowl, whisk the eggs, whole milk, heavy cream, granulated sugar, ¼ cup brown sugar, vanilla, 1 teaspoon of the cinnamon, and the salt until the sugar dissolves and the mixture is one even color. A few streaks left unwhisked will bake into rubbery patches, so give it a full minute.
4. Soak the bread: Pour the custard evenly over the bread and press the cubes down so each one gets wet. Cover the dish and refrigerate for at least 30 minutes, or overnight if you have the time. Overnight soaking is what gives the firmest custard and the least risk of a wet pocket in the center.
5. Make the streusel and top: In a small bowl, stir together the flour, ½ cup brown sugar, 1 teaspoon cinnamon, and ¼ teaspoon salt. Cut in the cold butter with your fingers or a pastry cutter until the mixture looks like coarse crumbs, then stir in the pecans if you’re using them. Scatter the streusel evenly over the soaked bread so every scoop gets some topping.
6. Bake and rest: Heat the oven to 350°F and bake uncovered for 40 to 50 minutes, until the casserole puffs, the streusel turns deep golden, and a thin knife inserted in the center comes out clean or with just a few moist crumbs. If the top browns early, tent the dish loosely with foil. Let it rest for 10 minutes before cutting, so the custard finishes setting.

Bread swaps and add-ins that still set

• Day-old French bread is the default here, but brioche makes it richer and challah lands somewhere in between. Sourdough adds a tang that plays well against the brown sugar, and all three hold up to the custard. Soft sandwich bread is the one to avoid, because it breaks down into paste.
• For a berry version, scatter 1 cup of blueberries or raspberries between the bread layers. Pat frozen berries dry first, since the ice that clings to them waters down the custard and slows the bake.
• A cream cheese version is worth the extra minute. Dot 4 ounces of softened cream cheese between the cubes before the custard goes on, and it melts into tangy pockets that break up the sweetness.
• I keep the streusel on the lighter side with ½ cup of flour, but if you want it cookie-thick, push it to ¾ cup and add another tablespoon of cold butter. Skip the extra sugar either way, because the custard’s already plenty sweet.
• Add ½ cup of chopped pecans or walnuts to the streusel for crunch, or trade the cinnamon for pumpkin pie spice in the fall. A batch of pumpkin muffins alongside it makes a full autumn brunch.
• For a cinnamon roll angle, drizzle a simple powdered sugar glaze over the cooled casserole instead of maple syrup, and put out brioche cinnamon rolls if you want to double down on the theme.

Keeping the center from staying wet

• Cut the bread into even 1-inch cubes. Oversized chunks hold the custard on the outside, so the middle of the dish bakes up wet while the edges dry out.
• Keep the custard at 2 cups whole milk and ½ cup heavy cream for 8 eggs. Adding more liquid to stretch the dish is the fastest route to a soggy center, and the set never firms up.
• Bake it uncovered so steam escapes and the streusel crisps. A covered dish traps that moisture and steams the top into a soft, pale layer.
• Test the middle with a thin knife. A few moist crumbs are fine, but any wet custard means it needs another 5 to 10 minutes in the oven.
• If the top browns before the center sets, tent the dish loosely with foil and keep baking. Foil over the streusel in the last stretch protects it without trapping much steam.
• A glass or ceramic dish holds heat longer than metal, so the center keeps setting after the casserole leaves the oven. In a metal pan, start checking the middle a few minutes earlier and lean on the knife test.

Cooled leftovers keep in the refrigerator for up to 3 days in an airtight container. Reheat covered at 350°F for 15 to 20 minutes, or warm a single serving in the microwave. To freeze, bake and cool the casserole completely, wrap it tightly, and freeze for up to 2 months; thaw overnight in the fridge before reheating. The custard can weep a little after freezing, so reheat it covered to bring it back together.

FAQ

Can I make french toast casserole ahead of time?

Yes, and that’s the best part of the recipe. Assemble the dish through the soak, cover it, and refrigerate for up to 24 hours. Add the streusel just before baking, then give it 5 to 10 extra minutes since the custard starts cold. Mix the topping the night before and keep it in the fridge in a bag if you want the morning to be quicker.

What is the best bread for french toast casserole?

Day-old French bread, brioche, challah, or sourdough all work because they are sturdy enough to soak without dissolving. The key is that the bread is dry, not fresh and soft. Soft sandwich bread turns mushy, so leave a sturdy loaf out overnight if that’s what you have.

Why is my french toast casserole soggy?

It usually comes down to soft bread, too much custard, or underbaking, and it doesn’t fix itself in the pan. Use day-old bread, keep the liquid at 2 cups milk and ½ cup cream for 8 eggs, and bake it uncovered until a knife in the center comes out clean. If the middle is still wet, bake another 5 to 10 minutes and test again.

Should I bake french toast casserole covered or uncovered?

Bake it uncovered so the streusel crisps and the steam escapes, which keeps the center from steaming soggy. If the top starts to brown before the middle sets, tent it loosely with foil for the last few minutes and uncover it again to finish.

Can you freeze french toast casserole?

You can freeze this casserole for up to 2 months. Bake and cool it completely, wrap the dish tightly in plastic wrap and then foil, and freeze. Thaw it overnight in the refrigerator, then reheat it covered at 350°F for 15 to 20 minutes or until warmed through.

This chicken spaghetti recipe bakes shredded chicken and spaghetti in a creamy, cheesy sauce until the edges bubble and the top goes golden. A quick flour-and-butter sauce, sharp cheddar, and a can of Ro-tel give it more flavor than the canned-soup version, and the pasta finishes in the oven instead of soaking up liquid on the counter. It fills a 9×13 pan, so it suits a potluck or a hungry family. If you like creamy pasta bakes, this pairs well with chicken parmesan on a dinner rotation.

The usual problem is a casserole that turns soupy or gummy. Canned soups and processed cheese carry a lot of water, and spaghetti boiled to full doneness keeps drinking sauce in the oven. I pull the noodles two minutes shy of done and thicken a simple roux, so the sauce clings to every strand instead of pooling in the dish. The same control makes spaghetti and meatballs work, too.

Ingredients

• 1 pound (454 g) spaghetti
• 2 pounds (900 g) boneless, skinless chicken breasts (about 3 large)
• 8 cups water, for poaching
• 1 dried bay leaf
• 4 tablespoons (57 g) unsalted butter
• 1 medium yellow onion, finely chopped (about 1 cup)
• 2 celery ribs, finely chopped (about ½ cup)
• 3 garlic cloves, minced
• ¼ cup (30 g) all-purpose flour
• 1½ cups reserved poaching liquid (or low-sodium chicken broth)
• 1 cup whole milk (or half-and-half)
• 1 can (10 ounces) Ro-tel diced tomatoes with green chiles, undrained
• 4 ounces (113 g) cream cheese, softened and cubed
• 2 cups (8 ounces / 227 g) shredded sharp cheddar, divided
• 1 teaspoon kosher salt, plus more for the pasta water
• ½ teaspoon freshly ground black pepper
• ½ teaspoon smoked paprika
• 2 tablespoons chopped fresh parsley, for serving (optional)

Instructions

1. Poach the chicken: Put the water and bay leaf in a large pot and bring it to a gentle boil. Add the chicken, reduce the heat to low, cover, and simmer for 18 to 20 minutes, until the thickest piece reads 165°F on a thermometer. Lift the chicken out to cool, then shred it with two forks. Strain the pot and save 1½ cups of the liquid.
2. Cook the spaghetti short of done: Bring the reserved poaching liquid plus enough fresh water to reach 4 quarts back to a boil and salt it well. Add the spaghetti and cook for 2 minutes less than the package says, so the center still has a firm bite. Drain it, saving 1 cup of the starchy water, and toss the noodles with a teaspoon of oil so they do not clump.
3. Build the base: Heat the oven to 375°F. Melt the butter in a large pot or Dutch oven over medium heat, then add the onion and celery. Cook for 5 to 6 minutes, until the onion turns translucent and soft, then stir in the garlic for 30 seconds, just until it smells sweet.
4. Make the cheese sauce: Sprinkle the flour over the vegetables and stir for a full minute to cook out the raw taste. Pour in the reserved liquid and the milk in a slow stream, whisking so no lumps form, and simmer for 3 to 4 minutes until the sauce coats the back of a spoon. Take the pot off the heat and stir in the cream cheese until smooth, then add 1½ cups of the cheddar a handful at a time. Stir in the Ro-tel, salt, pepper, and smoked paprika, then taste for salt.
5. Fold in the chicken and pasta: Add the shredded chicken and the spaghetti to the sauce and fold gently until every strand is coated. The mix should be thick but loose enough to spread; if it looks tight, splash in the reserved pasta water a little at a time. Spread it into a 9×13-inch baking dish and scatter the remaining ½ cup cheddar over the top.
6. Bake until bubbly: Bake for 20 to 25 minutes, until the sauce bubbles around the edges and the top cheese melts and turns light golden. If the top needs more color, run it under the broiler for 1 to 2 minutes, watching closely so the cheese does not scorch.
7. Rest and serve: Let the casserole rest for 5 to 10 minutes before you cut into it, so the sauce sets and the portions hold together. Scatter the parsley on top if you like and serve straight from the dish while it is hot.

What I Tried and Skipped

• Canned cream soups plus Velveeta is the fastest route, but the sauce stays loose and the casserole goes soupy once the pasta sits. I build a quick roux and grate real cheddar instead, which holds the noodles in a coating rather than a pool.
• Boiling the spaghetti to full doneness before baking turns it to mush by the time the cheese bubbles. Pulling it two minutes early and letting the oven finish the pasta keeps a firm bite.
• A true one-pot version where the noodles cook in the sauce sounds tidy, but starchy pasta water and milk get gluey over that much time. Cooking the spaghetti separately and folding it in is more predictable.
• A rotisserie chicken is a fine shortcut and saves the poach, but the poaching liquid is what makes the sauce taste like chicken instead of milk and flour. When I have 20 minutes, I keep the homemade broth.
• Pre-shredded cheddar is convenient, but its starch coating melts grainy in a sauce. Grating a block on the box grater gives a smoother, glossier finish.
• Boneless breasts poach evenly and keep the sauce pale, while thighs add richness but darken the color. I stay with breasts for the classic look, and use thighs when I want a deeper flavor.

What to Serve With Chicken Spaghetti

• Creamy mashed potatoes are a double-starch plate that a lot of people love, but the lighter choice is a simple green vegetable.
• Golden garlic bread is the easy answer for sopping up any extra sauce left in the dish.
• Green bean casserole rounds the meal out for a holiday table or a potluck.
• Classic coleslaw cuts the richness with a cold, tangy crunch.
• A crisp green salad or steamed broccoli works just as well when you want something quick and fresh on the side.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days, and reheat them covered in a 350°F oven for about 20 minutes with a splash of milk or broth, since the pasta keeps soaking up sauce as it sits. To freeze, assemble the casserole in a freezer-safe dish without baking, wrap it tightly, and freeze for up to 2 months. Thaw it overnight in the refrigerator, then bake as directed, adding 5 to 10 minutes if it is still cold in the middle.

FAQ

Can I make chicken spaghetti ahead of time?

Yes, and it is a strong make-ahead dish. Assemble the casserole all the way up to the cheese topping, cover it, and refrigerate for up to 3 days. Bake it straight from the fridge, adding about 5 to 10 minutes to the time, or freeze it unbaked for up to 2 months and thaw it overnight before baking.

Why did my chicken spaghetti turn out soupy?

It is usually too much liquid and pasta cooked too long. Cheesy casseroles tighten as they bake, but the noodles keep absorbing sauce once the dish rests, so a sauce that looks perfect in the pot can still pool later. Cook the spaghetti two minutes shy of done, keep the sauce thick enough to coat a spoon, and let the baked dish sit for 5 to 10 minutes before serving.

Can I use rotisserie chicken instead of poaching?

Yes, pull the meat from one store-bought rotisserie chicken, which gives you about 3 to 4 cups, and use low-sodium chicken broth in place of the poaching liquid. That saves about 20 minutes of cooking time. The sauce will taste a little less chicken-forward because the broth replaces the liquid the chicken cooked in, which is why I poach when I have the time.

Can I use canned cream soup instead of the flour sauce?

Yes, and that is the old-school shortcut. Stir one can of cream of chicken and one can of cream of mushroom soup into the sauteed vegetables in place of the flour, liquid, and milk, then skip the cream cheese if you want. It will be saltier and thinner, so leave out the added salt until you taste it, and cut back on any liquid you add.

Can I use Velveeta instead of cheddar?

You can, and it melts into a very smooth sauce. Use about 12 ounces of cubed Velveeta in place of the cream cheese and cheddar and stir it in over low heat until it melts. The trade-off is a softer, saltier sauce that sets thinner as it cools, so I still add a little cheddar on top for flavor and color.

What pasta works best for chicken spaghetti?

Long spaghetti is the classic choice, and thin spaghetti cooks a touch faster, so check it early. Penne or rotini also work and their ridges hold more sauce, which makes the casserole a little less likely to run. Whichever shape you use, cook it short of al dente so it does not overcook in the oven.
