Learn the simple technique to achieve roast potatoes with a perfectly crunchy, golden exterior and a light, fluffy interior every time you cook. This recipe focuses on the method for ultimate comfort food.

Ingredients

Scale
  • 3 lbs Russet or Yukon Gold potatoes, peeled and cut into uniform 1.5-inch chunks
  • 1/2 cup vegetable oil or duck fat (for maximum crispiness)
  • 1 tablespoon coarse kosher salt
  • 1 teaspoon black pepper
  • 4 cloves garlic, smashed
  • 3 sprigs fresh rosemary
  • 1/4 cup grated Parmesan cheese (optional, for finishing)

Instructions

  1. Place the cut potatoes in a large pot and cover them with cold water. Add 1 teaspoon of the kosher salt. Bring the water to a boil over high heat.
  2. Boil the potatoes for 8 to 10 minutes until the edges just start to soften. You want them tender on the outside but still firm in the center.
  3. Drain the potatoes completely in a colander. Let them sit for 5 minutes to allow excess steam to escape.
  4. Gently shake the colander vigorously for about 30 seconds. This roughs up the edges of the potatoes, creating the starchy surface needed for maximum crunch.
  5. Preheat your oven to 425°F (220°C). Pour the oil or duck fat into a large, heavy-duty roasting pan and place it in the oven while it preheats for 5 minutes. The fat must be hot before adding the potatoes.
  6. Carefully remove the hot pan from the oven. Add the roughed-up potatoes to the hot fat, ensuring they are in a single layer if possible. Turn them gently to coat them in the fat.
  7. Sprinkle the remaining salt and pepper over the potatoes. Add the smashed garlic cloves and rosemary sprigs to the pan.
  8. Return the pan to the oven and roast for 25 minutes.
  9. Remove the pan, turn the potatoes using a spatula, and return them to the oven for another 20 to 30 minutes, or until they are deeply golden brown and very crispy.
  10. If using, sprinkle the Parmesan cheese over the potatoes during the last 5 minutes of roasting. Serve immediately as your ultimate side dish.

Notes

  • Using duck fat or beef drippings instead of vegetable oil provides superior flavor and crispness.
  • Do not overcrowd the roasting pan; use two pans if necessary to ensure the potatoes roast instead of steam.
  • For extra fluffy insides, you can add 1/2 teaspoon of baking soda to the boiling water in Step 1.
