What Are Crispy Potato Squares?

Crispy potato squares are made from parboiled or mashed potatoes, seasoned well, shaped into a flat layer, chilled or rested, then cut into squares and cooked until deeply golden. The technique allows the potatoes to develop a firm structure, which leads to an extra-crispy crust during cooking.

Unlike regular roasted potatoes:

  • They have even crispiness on all sides
  • They hold their shape beautifully
  • They can be flavored endlessly

Ingredients for Crispy Potato Squares

Simple ingredients are the key to great potatoes. Quality seasoning makes all the difference.

Main Ingredients

  • 2½ pounds (1.2 kg) potatoes (Yukon Gold or Russet)
  • 2 tablespoons cornstarch or potato starch
  • 3 tablespoons olive oil or melted butter
  • Salt, to taste
  • Black pepper, to taste

Flavor Add-Ins (Optional but Recommended)

  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon paprika or smoked paprika
  • 1 tablespoon fresh parsley or chives, chopped
  • ½ cup grated Parmesan cheese (optional)

Choosing the Right Potatoes

The type of potato matters.

  • Yukon Gold: Creamy inside, naturally flavorful, great balance
  • Russet Potatoes: Extra fluffy interior, very crispy exterior

Avoid waxy potatoes like red potatoes, as they don’t crisp as well.

Preparing the Potatoes

  1. Peel the potatoes (optional, but recommended for smooth texture).
  2. Cut into large chunks for even cooking.
  3. Place in a large pot and cover with cold salted water.
  4. Bring to a boil and cook until fork-tender, about 15–18 minutes.
  5. Drain completely and let steam dry for 5 minutes.

Removing excess moisture is essential for crispiness.

Mashing and Seasoning the Potatoes

  1. Transfer the potatoes to a large bowl.
  2. Mash until smooth but not gluey.
  3. Add salt, pepper, garlic powder, onion powder, and paprika.
  4. Mix in cornstarch and olive oil or butter.
  5. Fold in herbs or Parmesan if using.

The starch helps create a crispy outer layer during cooking.

Shaping the Potato Slab

  1. Line a baking dish or tray with parchment paper.
  2. Spread the potato mixture evenly to about ¾-inch thickness.
  3. Smooth the surface with a spatula.
  4. Refrigerate for 30–60 minutes until firm.

Chilling helps the potatoes hold their shape when cut.

Cutting Perfect Potato Squares

  1. Lift the chilled potato slab from the tray.
  2. Use a sharp knife to cut into even squares.
  3. Wipe the knife between cuts for clean edges.

Uniform size ensures even cooking and consistent crispiness.
