Follow this foolproof method to make roast potatoes with a perfectly golden, crunchy exterior and a light, fluffy interior every time you roast them.

Ingredients

Scale
  • 3 lbs Russet or Yukon Gold potatoes, peeled and cut into uniform 1.5-inch chunks
  • 1/2 cup duck fat or vegetable oil (must be hot)
  • 2 tablespoons all-purpose flour
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 4 sprigs fresh rosemary
  • 4 cloves garlic, smashed

Instructions

  1. Place the potato chunks in a large pot and cover with cold, salted water. Bring to a boil over high heat.
  2. Cook the potatoes for 8 to 10 minutes after the water starts boiling. You want the edges to just begin to soften, but the centers should remain firm.
  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 to rough up the edges of the potatoes. This creates the starchy surface needed for maximum crispiness.
  5. Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). Place a large, heavy-duty roasting pan in the oven while it preheats.
  6. Carefully remove the hot pan from the oven. Add the duck fat or oil to the hot pan and swirl to coat the bottom. The fat should shimmer immediately.
  7. Sprinkle the flour, salt, and pepper over the roughed-up potatoes and toss gently to coat them lightly.
  8. Place the potatoes into the hot fat in a single layer, ensuring they have space between them. Do not overcrowd the pan.
  9. Roast for 20 minutes.
  10. After 20 minutes, turn the potatoes using a spatula. Add the rosemary sprigs and smashed garlic cloves to the pan around the potatoes.
  11. Return the pan to the oven and roast for another 25 to 35 minutes, turning once halfway through, until the potatoes are deep golden brown and crunchy.
  12. Remove from the oven and serve immediately as your ultimate comfort side dish.

Notes

  • Using duck fat provides superior flavor and crispness, but vegetable oil works well for an easy oven recipe.
  • Do not skip the step of shaking the colander; this roughing up creates the necessary texture for a crunchy roast potato.
  • For extra flavor, you can add 1/4 cup of grated Parmesan cheese during the last 10 minutes of roasting.
