Ingredients

Scale
  • 3 lbs Russet or Yukon Gold potatoes, peeled and cut into 1.5-inch chunks
  • 1/2 cup vegetable oil or duck fat
  • 1 teaspoon baking soda
  • 1 tablespoon coarse salt
  • 1 teaspoon black pepper
  • 4 cloves garlic, smashed
  • 3 sprigs fresh rosemary

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Place the potato chunks in a large pot and cover with cold water. Add the baking soda and a pinch of salt. Bring the water to a boil and cook for 8 minutes until the edges of the potatoes start to look soft.
  3. Drain the potatoes completely in a colander. Shake the colander gently to rough up the edges of the potatoes; this creates the starchy coating needed for crispiness.
  4. Heat the oil or fat in a large, heavy roasting pan in the preheated oven for 10 minutes until shimmering hot.
  5. Carefully place the roughed-up potatoes into the hot fat, turning them once to coat. Do not overcrowd the pan.
  6. Roast for 30 minutes.
  7. Remove the pan from the oven. Add the smashed garlic cloves and rosemary sprigs around the potatoes. Season with the coarse salt and pepper.
  8. Turn the potatoes using a spatula to expose the uncooked sides.
  9. Return the pan to the oven and roast for another 25 to 35 minutes, turning every 15 minutes, until the potatoes are deep golden brown and very crispy.
  10. Remove from the oven and serve immediately.

Notes

  • For the crispiest results, use Russet potatoes, as their high starch content helps create a fluffy inside and rough exterior.
  • Do not skip the parboiling step with baking soda; this is key to breaking down the starches.
  • If you want extra flavor, toss the potatoes with 1/4 cup grated Parmesan cheese during the last 10 minutes of roasting.
