Crispy Accordion Potatoes with Roasted Garlic Butter

Sharing is caring!

These accordion potatoes are cut with a tight accordion crosshatch, quickly simmered so they cook through fast, then roasted on a hot sheet pan for crisp edges and deep golden color. Before baking, you brush them with smoky paprika olive oil. At the end, roasted garlic gets mashed into butter with rosemary plus thyme or parsley—use whichever you have.

Ingredients

Potatoes

• 4 medium Yukon Gold potatoes (Russets work too)

• Flaky sea salt + chopped chives (optional, to finish)

Seasoned olive oil (for brushing before baking)

• 2 tablespoons olive oil

• 1 teaspoon kosher salt

• 1/2 teaspoon black pepper

• 1/2 teaspoon smoked paprika

Roasted garlic herb butter

• 1 whole garlic bulb

• 1–2 teaspoons olive oil (for roasting the garlic)

• 1/4 cup butter (½ stick), softened

• 2 teaspoons fresh rosemary, finely minced

• 2 teaspoons fresh thyme, finely minced (optional)

• 2 tablespoons fresh parsley, finely chopped (optional)
  (Use thyme or parsley—both work. If you love herbs, you can do a little of each.)

Instructions

1) Roast the garlic

1. Heat oven to 425°F (220°C).

2. Slice the top ¼ inch off the garlic bulb so the cloves are exposed.

3. Place on foil, drizzle with 1–2 tsp olive oil, and wrap into a loose packet.

4. Roast 35–45 minutes, until the cloves are soft and caramelized.

2) Preheat the sheet pan

• While the garlic roasts, place a large sheet pan in the oven to preheat.

3) Cut potatoes into rectangles

1. Trim a thin slice off all 4 sides of each potato to square it off.

2. Slice into ¼-inch thick rectangles/planks.

3. Keep them in cold water as you work to prevent browning.

4) Cut the accordion pattern (with skewers/chopsticks)

1. Place one potato rectangle on a cutting board.

2. Lay two wooden skewers (or chopsticks) lengthwise along the two long sides of the potato. This stops your knife so you don’t slice all the way through.

3. Using a sharp knife, make thin cuts straight across the potato, very close together, letting the skewers stop the blade.

4. Flip the potato over, reset the skewers if needed, and slice again on a 45° diagonal, same close spacing.

5) Parboil (5–6 minutes)

1. Bring a pot of salted water to a gentle boil.

2. Add the potato planks and simmer 5–6 minutes (tender, not falling apart).

3. Lift them out carefully with a slotted spoon/spider.

4. Let them steam-dry 2–3 minutes, then pat dry gently.

6) Mix the seasoned olive oil

• Stir together olive oil, kosher salt, pepper, and smoked paprika.

7) Bake (build the crust)

1. Carefully remove the hot sheet pan and lightly oil it.

2. Brush both sides of each plank with the seasoned olive oil.

3. Arrange in a single layer on the hot pan.

4. Bake 12–15 minutes, until the bottoms are crisp and deeply golden.

5. Flip and bake 10–15 minutes more, until browned and sizzling at the edges.

8) Make the roasted garlic herb butter

1. Squeeze the roasted garlic cloves into a bowl and mash into a paste.

2. Mix with softened butter, rosemary, and thyme or parsley (your choice).

9) Finish with roasted garlic butter

1. Pull the pan out and brush the tops generously with the roasted garlic butter, working it into the cuts.

2. Return to the oven 2–4 minutes to melt and set.

3. Optional: broil 30–90 seconds for extra crunch—watch closely.

10) Serve

Let the potatoes sit 5 minutes on the pan (they crisp up even more). Finish with flaky sea salt and chives if you want.

Tips & Tricks for Crispy Accordion Potato Rectangles

• Make the rectangles first (it’s worth the extra minute). Trimming the sides gives you flat, even planks that sit steady on the pan and brown more evenly than rounded slices.

• Keep the planks around ¼ inch thick. Thinner planks get fragile once you start slicing the accordion pattern. Thicker than ¼ inch takes longer to crisp and won’t open up as nicely.

• Skewers are your insurance policy. Set one along each long side so your knife stops automatically. It keeps the potato in one piece and makes the cuts consistent—even if you’re rushing.

• Go for “lots of cuts,” not “deep cuts.” Tight spacing is what creates that accordion look. The goal is many thin slices while leaving a small hinge at the bottom.

• Simmer, don’t blast them with a hard boil. A gentle boil for 5–6 minutes softens the inside without breaking the planks. If the water is violently rolling, the crosshatch can split.

• Steam-dry after draining. Let the potatoes sit in the colander 2–3 minutes before patting dry. That little bit of steam helps surface moisture evaporate so you get crispier edges in the oven.

• Preheat the sheet pan like it’s cast iron. Starting on a hot pan gives you instant sizzle and better browning. If you skip this, the bottoms tend to go soft.

• Brush with the smoked paprika oil first. It builds flavor and color where you actually want it—on the crisp crust—without risking burnt herbs.

• Save the roasted garlic butter for the end. Butter and herbs can darken too fast at 425°F. Brushing it on during the last few minutes keeps the garlic sweet and the herbs fresh-tasting.

• Broil only when you’re already happy with the color. Think of the broiler as a quick “final crunch,” not the main cooking step. Thirty seconds can be enough.

• Want extra-crispy edges? Don’t crowd the pan. Leave a little space between planks so hot air can circulate and the potatoes roast instead of steaming.

• If a plank breaks, roast it anyway. Broken pieces still crisp up beautifully—and they’re usually the first ones to get “taste-tested” off the tray.
