These oven baked 3-ingredients crispy accordion potatoes look fancy enough for company but are simple enough for a busy weeknight. The magic is in a clever slicing trick my daughter showed me—those tight little cuts let the potatoes stretch out like an accordion, so the ridges get unbelievably crunchy while the centers stay soft and fluffy. This is a fun, hands-on recipe that feels a bit like a project, and it’s perfect for getting kids involved in the kitchen without a lot of fuss or ingredients.
Serve these crispy accordion potatoes straight from the baking sheet while they’re still hot and crackly. They’re wonderful alongside roasted chicken, meatloaf, or grilled pork chops, and they make burgers or sloppy joes feel extra special. Add a simple green salad or steamed veggies to round things out, and set out a few dipping options like ketchup, ranch, or a little bowl of sour cream if you don’t mind going beyond the base three ingredients. They’re also a great game-day snack or movie-night treat, eaten with fingers right off the tray.
Oven Baked 3-Ingredients Crispy Accordion PotatoesServings: 4
Ingredients
2 pounds small to medium Yukon Gold or russet potatoes (about 6–8 potatoes)
3 tablespoons neutral oil (such as canola, vegetable, or light olive oil)
1 teaspoon kosher salt, plus more to taste
Directions
Preheat your oven to 400°F (200°C). Line a well-used baking sheet with parchment paper if you’d like easier cleanup, but it’s fine to cook them directly on the pan for extra crisp edges.
Scrub the potatoes well and pat them completely dry with a clean towel. Leave the skins on for better texture and to help them hold their shape.
Working one potato at a time, place it lengthwise on your cutting board. Set a chopstick or the handle of a wooden spoon along each long side of the potato. These will act as guards so you don’t slice all the way through.
Use a sharp knife to cut thin slices crosswise along the potato, about 1/8 inch apart, stopping when the knife hits the chopsticks so the potato stays connected at the bottom. Take your time—the closer and more even the slices, the crispier the ridges will be.
Flip the potato over so the uncut side is now facing up. Put the chopsticks back along the sides. This time, slice on a slight diagonal, again about 1/8 inch apart, creating a crisscross pattern that goes almost—but not quite—all the way through. When you gently pull the ends, the potato should stretch a bit like an accordion.
Repeat the slicing process with the remaining potatoes, arranging each finished potato on the baking sheet with a little space between them so air can circulate.
In a small bowl, stir together the oil and salt. Brush this mixture generously over the tops and sides of each potato, making sure it seeps into the cuts as much as possible. If you don’t have a brush, drizzle the oil over and use clean hands to rub it in.
Gently pull on the ends of each potato to fan it out slightly, encouraging those accordion folds to open up. This helps more of the surface get exposed to the heat for maximum crunch.
Place the baking sheet on the middle rack of the oven and bake for 35–45 minutes, turning the pan once halfway through. Baking time will depend on the size of your potatoes and your oven.
About halfway through baking, carefully use a spatula or tongs to loosen any potatoes that are sticking and gently separate their ridges if they’ve closed up. If the tops look dry, spoon a little of the hot oil from the pan over them to encourage extra crispiness.
The potatoes are done when the ridges are deep golden brown and very crisp, and the centers are tender when pierced with the tip of a knife. If they’re browning too fast, loosely tent with foil for the last few minutes; if they’re not browning enough, move the tray up one rack near the end.
Remove from the oven and let the potatoes sit on the baking sheet for 3–5 minutes. Sprinkle with a pinch more salt if you like, then gently stretch them out once more so those golden, crunchy ridges and soft centers are visible. Serve right from the well-loved baking sheet while hot and crisp.
Variations & Tips
If you have picky eaters, keep some potatoes plain with just oil and salt, and let everyone add their own toppings at the table—ketchup for the kids and maybe a little hot sauce or sour cream for the adults. For a slightly different flavor while still honoring the 3-ingredient idea, you can swap the neutral oil for melted butter or use a mild olive oil; either one adds a cozy, richer taste. If you want to prep ahead, slice the potatoes earlier in the day and keep them in a bowl of cold water in the fridge to prevent browning; just dry them very well before oiling and baking so they crisp properly. For extra-crispy edges, choose smaller potatoes so more surface area can brown, and avoid crowding the pan. If your family likes things well-seasoned but you want to keep the base recipe simple, bake them with only oil and salt, then sprinkle on garlic powder, pepper, or herbs after baking for anyone who wants the extra flavor. Finally, if your knife skills feel a little rusty, practice on one potato first and cook it as a “tester”—kids love getting to taste the experimental one while the rest finish baking.
