Extra-Crispy Roasted Cubed PotatoesGolden brown and crisp on the outside and tender inside, roasted cubed potatoes will always make an excellent side dish for breakfast, brunch, or dinner. Using evenly shaped cubes ensures that your potatoes all cook at the same rate, for uniform extra-crispiness. Heat your oven to 400° F with a sheet pan in the oven as it heats. Preheating the sheet pan helps sear the edges of the potatoes faster, which is a very good thing.
While the oven and sheet pan heat, toss your cubed potatoes in a mixing bowl with olive or vegetable oil and season liberally with salt (and pepper and other spices if desired). Using a potholder or oven mitt, carefully remove the hot sheet pan from the oven and spread out the cubed potatoes in an even layer. Return to the oven and roast until the bottoms are brown and crispy, about 10 minutes, then use a spatula to stir the potato cubes and continue to roast until uniformly golden brown and crispy. Note: An air-fryer may also be used to cook cubed potatoes. You’ll want them in the fryer for about 10 minutes at 400° F.
