Golden and crunchy outside, fluffy and tender inside—these simple oven-roasted potatoes deliver maximum crispiness without deep frying.
How to make potatoes extra crispy in the oven comes down to a few small techniques that make a huge difference: choosing the right potatoes, removing excess starch, drying them thoroughly, using enough oil, and roasting them at high heat without overcrowding the pan. When done correctly, each potato develops deeply browned, crunchy edges while staying soft and fluffy in the center. This easy method requires basic pantry ingredients and works beautifully as a side dish for chicken, steak, fish, or almost any weeknight dinner.
Prep Time: 15 minutes | Cook Time: 40–50 minutes | Servings: 4–6
Ingredients
- 2 lb (900 g) Yukon Gold or russet potatoes
- 3 tablespoons olive oil
- 1 tablespoon cornstarch
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- 1 teaspoon dried oregano
- 3/4 teaspoon salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper
- 1/4 teaspoon red pepper flakes, optional
- 2 tablespoons finely chopped fresh parsley
Step-by-Step Instructions
- Preheat the oven: Heat your oven to 425°F (220°C). Place a large metal baking sheet inside while the oven heats. Starting with a hot pan helps the potatoes begin browning as soon as they touch the surface.
- Cut the potatoes evenly: Scrub the potatoes well and cut them into roughly 1 1/2-inch (4 cm) chunks. Keeping the pieces similar in size helps them cook evenly while leaving plenty of edges to become crispy.
- Remove excess starch: Place the potatoes in a bowl of cold water and let them soak for about 15–20 minutes. Drain thoroughly, then pat them completely dry with clean kitchen towels or paper towels. Any excess surface moisture can create steam instead of crunch.
- Add the crispy coating: Transfer the dry potatoes to a large bowl. Sprinkle with cornstarch, garlic powder, paprika, oregano, salt, black pepper, and optional red pepper flakes. Toss until every piece has a light, even coating.
- Add the oil: Drizzle in the olive oil and toss again until the potatoes are glossy and evenly coated. The thin combination of starch and oil creates a beautifully crisp exterior in the hot oven.
- Arrange in one layer: Carefully remove the hot baking sheet from the oven. Spread the potatoes across it in a single layer, leaving some space between each piece. Place a flat cut side against the pan whenever possible for deeper browning.
- Roast until deeply golden: Bake for 20–25 minutes without moving the potatoes. Flip them, then continue roasting for another 20–25 minutes until the surfaces are crisp, browned, and slightly blistered.
- Finish and serve: Sprinkle the hot potatoes with fresh parsley and additional salt if needed. Serve immediately while the exterior is at its crispiest.
Tips for Extra-Crispy Oven Potatoes
- Dry them completely: Water is one of the biggest enemies of crispy roasted potatoes.
- Use a metal baking sheet: Metal generally produces stronger browning than a glass baking dish.
- Don't overcrowd the pan: Potatoes packed closely together trap steam and become soft.
- Use cornstarch: A small amount creates an extra-dry surface that crisps beautifully.
- Give them time: Don't flip too early. Let the first side develop a deep golden crust before turning.
- Serve immediately: Roasted potatoes naturally soften as they sit.
Serving Suggestions
These crispy oven potatoes pair perfectly with grilled chicken, roasted chicken, steak, salmon, shrimp, or fresh garden salad. You can also serve them with garlic yogurt sauce, ranch dressing, spicy mayo, or a creamy herb dip. For an extra burst of flavor, finish them with fresh lemon juice, Parmesan, or additional chopped herbs.
Storage and Reheating
Store leftover potatoes in an airtight container in the refrigerator for up to 3–4 days. To bring back their crispy texture, spread them on a baking sheet and reheat at 425°F (220°C) for about 8–12 minutes. An air fryer at 375°F (190°C) also works well. Avoid the microwave when possible because it tends to soften the crispy exterior.
Frequently Asked Questions
Why aren't my potatoes getting crispy in the oven?
The most common causes are excess moisture, overcrowding, insufficient oil, or an oven that isn't hot enough. Dry the potatoes thoroughly and give each piece enough room for hot air to circulate.
Does cornstarch make roasted potatoes crispier?
Yes. A light coating of cornstarch helps create a dry, textured exterior that becomes especially crunchy during roasting. You only need a small amount.
Should I boil potatoes before roasting them?
You don't have to, but parboiling is another excellent technique for extremely crispy potatoes. Boil the chunks briefly until the outsides begin to soften, drain well, rough up their surfaces, then season and roast until deeply golden.
