Once everything is blended with cream, basil, and broth, the sauce turns silky and smooth, then finishes cooking right in the oven with the spaghetti.

This is the kind of dinner that looks colorful, tastes cozy, and doesn’t leave you standing over the stove the whole time. It’s simple enough for a weeknight, but it still feels like something a little more special when it lands on the table.

Why You’ll Love This Roasted Veggie Pasta

This roasted veggie pasta keeps things easy without tasting plain. Roasting the vegetables first gives the sauce a fuller flavor, and blending everything together makes it creamy without needing a long list of ingredients. The spaghetti cooks right in the sauce, which means fewer dishes and even more flavor in every bite.

You’ll love this recipe because:

• the sauce is rich, smooth, and full of roasted vegetable flavor
• roasted garlic gives it a softer, deeper taste than garlic powder
• everything bakes in one dish
• spaghetti works beautifully with the creamy sauce
• it looks vibrant and feels comforting at the same time

Ingredients

For the roasted vegetables

• 1 cup cherry tomatoes
• 1/2 red bell pepper, chopped
• 1/2 yellow or orange bell pepper, chopped
• 1/2 medium zucchini, chopped
• 1 small red onion, cut into wedges
• 1 whole garlic bulb
• 1 1/2 tablespoons olive oil

For the seasoning

• Salt, to taste
• Black pepper, to taste
• 1 teaspoon Italian seasoning
• 1/4 teaspoon red pepper flakes, optional

For the sauce

• 3/4 cup heavy cream
• 1 cup vegetable broth
• Small handful fresh basil

For the pasta

• 7 ounces spaghetti

Equipment

• Deep oven-safe baking dish
• Small piece of foil
• Blender or immersion blender
• Spoon or spatula

Instructions

1. Roast the vegetables
Preheat the oven to 425°F. Add the cherry tomatoes, bell peppers, zucchini, and red onion to a deep baking dish. Drizzle with olive oil and season with salt, black pepper, Italian seasoning, and red pepper flakes, if using.

Cut the top off the garlic bulb, drizzle with a little oil, wrap in foil, and place it in the dish. Roast for 30 to 35 minutes, until the vegetables are soft and the tomatoes have burst.

2. Blend the sauce
Squeeze the roasted garlic cloves into the dish. Add the heavy cream, vegetable broth, and basil, then blend until smooth. If the sauce seems too thick, add a small splash of broth.

3. Add the spaghetti
Break the spaghetti in half and add it to the sauce. Press it down gently so most of it is covered.

4. Bake the pasta
Return the dish to the oven and bake for 18 to 22 minutes, stirring once halfway through. If needed, add a splash of broth or hot water so the pasta cooks evenly.

5. Serve
Stir well, then serve warm with extra basil, red pepper flakes, or Parmesan on top.

Tips and Tricks

• Use a deep baking dish: This helps hold enough liquid for the spaghetti to cook properly.
• Do not skip the roasted garlic: It adds a sweeter, more rounded flavor that makes the sauce taste much better.
• Cut the vegetables into similar-sized pieces: That way they roast evenly and blend more smoothly.
• Stir halfway through baking: This keeps the spaghetti from clumping and helps it cook evenly.
• Add extra liquid only if needed: Ovens and baking dishes vary, so keep an eye on the sauce near the end.
• Blend until fully smooth: A silky sauce works best here because it coats the spaghetti more evenly.

Variations

This version is already full of flavor, but you can still tweak it depending on what you have on hand.

• Add a little grated Parmesan to the sauce for an even richer finish
• Stir in spinach at the end and let it wilt into the hot pasta
• Add cooked chicken on top to turn it into a heartier dinner
• Use a little more red pepper flakes if you want more heat
• Finish with burrata or torn mozzarella for a creamier serving option

Storage and Reheating

Store leftovers in an airtight container in the fridge for up to 3 days.

To reheat, warm it gently on the stove or in the microwave with a splash of broth, cream, or water to loosen the sauce. The pasta will continue soaking up liquid as it sits, so adding a little moisture helps bring it back to life.

Frequently Asked Questions

Can I use another pasta shape?

Yes, but spaghetti works especially well in this version. Short pasta can work too, though cooking time may vary slightly.

Do I have to roast the garlic separately?

Yes, it’s worth it. Wrapping the garlic in foil keeps it soft and prevents it from drying out or burning in the oven.

Can I make the sauce ahead of time?

Yes. You can roast and blend the sauce ahead, then refrigerate it until you’re ready to bake it with the spaghetti.

What if my sauce gets too thick?

Add a splash of broth or hot water and stir. That usually fixes it quickly.

Can I make it more cheesy?

Absolutely. Parmesan on top or mixed into the sauce works really well here.

This is the kind of pasta that works when you want something comforting without making a heavy cream sauce. The tomatoes do most of the work here. Once roasted, they become jammy and concentrated, and when blended with butter and garlic, they turn into a smooth, glossy tomato butter that coats hot pasta beautifully.

Ingredients

• 1 1/2 lb cherry tomatoes

• 1 whole garlic bulb

• 3 tbsp olive oil

• 1 tsp salt, plus more for pasta water

• 1/2 tsp black pepper

• 1/4 tsp red pepper flakes, or more to taste

• 4 tbsp unsalted butter, softened (vegan butter, optional)

• 1/4 cup fresh basil leaves

• 1 to 2 tsp balsamic glaze

• 12 oz pasta, such as spaghetti, linguine, or fettuccine

• 1/3 to 1/2 cup reserved pasta water

• Freshly grated Parmesan, for serving

• Extra basil, for serving

Instructions

1. Roast the tomatoes and garlic

Preheat your oven to 400°F (200°C).

Add the cherry tomatoes to a baking dish or sheet pan. Drizzle with olive oil and season with salt, black pepper, and red pepper flakes. Toss well so the tomatoes are evenly coated.

Slice the top off the garlic bulb just enough to expose the cloves. Set it on a piece of foil, drizzle with a little olive oil, then wrap it loosely in the foil.

Place the tomatoes and garlic in the oven. Roast for 30 to 35 minutes, or until the tomatoes have burst and look soft and slightly caramelized. The garlic should be very soft when pressed.

2. Cook the pasta

While the tomatoes roast, bring a large pot of well-salted water to a boil. Cook the pasta until al dente according to the package directions.

Before draining, reserve 1/2 cup of the pasta water. Set it aside.

3. Make the tomato butter sauce

Transfer the roasted tomatoes to a blender or food processor. Squeeze the soft roasted garlic cloves out of their skins and add them in. Add the softened butter, basil, and balsamic glaze.

Blend until mostly smooth. Taste the sauce and adjust if needed. Add a pinch more salt, more chili flakes, or another small drizzle of balsamic if you want a slightly deeper flavor.

4. Toss everything together

Pour the warm sauce into a large skillet or pot over low heat. Add the drained pasta and toss well.

Pour in a little reserved pasta water at a time until the sauce loosens and turns glossy. You want it silky enough to coat the pasta without becoming watery.

5. Serve

Divide the pasta into bowls and finish with grated Parmesan and extra basil. Serve right away while the sauce is warm and smooth.

Tips and Tricks

• Use ripe cherry tomatoes for the best flavor. The sweeter they are, the richer and rounder the sauce will taste after roasting.

• Roast the tomatoes until they look collapsed and a little jammy, not just softened. That deeper roast gives the sauce much more flavor.

• Let the garlic cook until fully soft all the way through. If it is still firm in the middle, the sauce can taste harsher than it should.

• Don’t forget to save some pasta water before draining. A few spoonfuls help loosen the sauce and make it coat the pasta better.

• Add the balsamic glaze slowly. A little goes a long way, and you want it to deepen the sauce, not take over.

• Blend the sauce while the tomatoes are warm, not scorching hot. It will come together more smoothly and be easier to handle.

• If the sauce feels too thick, loosen it with a splash of hot pasta water or a drizzle of olive oil.

• If the sauce feels too loose, let it sit over low heat for a minute before tossing with the pasta.

• Finish with freshly grated Parmesan just before serving. It adds saltiness and helps round out the flavor.

• Store leftovers in the fridge for up to 3 days. Reheat gently with a splash of water so the sauce turns silky again instead of drying out.
