Ingredients

Scale

Potatoes and Herbs

  • 3 pounds small Yukon gold potatoes
  • 1 tablespoon chopped fresh rosemary
  • 3 rosemary sprigs

Butter and Seasonings

  • 6 tablespoons salted butter, melted
  • 46 cloves garlic, smashed
  • Kosher salt and black pepper, to taste
  • Flaky sea salt, for serving

Instructions

  1. Preheat the Oven: Begin by preheating your oven to 425°F (220°C) to ensure a hot cooking environment, key for achieving crispiness on the potatoes.
  2. Prepare the Potatoes: Wash and dry the Yukon gold potatoes thoroughly. If the potatoes are larger, halve or quarter them to ensure even roasting. Leaving the skins on adds texture and nutrients.
  3. Mix Butter and Herbs: In a large bowl, combine the melted butter with the chopped fresh rosemary, smashed garlic cloves, kosher salt, and black pepper. Stir well to infuse the butter with the aromatics.
  4. Toss Potatoes in Butter Mixture: Add the potatoes to the bowl with the butter and herb mixture and toss until each piece is well coated.
  5. Arrange Potatoes in Baking Dish: Spread the potatoes in a single layer on a large baking sheet or roasting pan. Tuck the rosemary sprigs among the potatoes for additional flavor during roasting.
  6. Roast Until Crispy: Place the baking sheet in the preheated oven and roast for 35-45 minutes, turning the potatoes halfway through to ensure even browning. The potatoes should be golden brown and crispy on the outside and tender inside.
  7. Serve and Season: Remove from the oven, discard the rosemary sprigs, and sprinkle the potatoes with flaky sea salt before serving for an extra burst of flavor and texture.

Notes

  • Yukon gold potatoes are preferred for their creamy texture and thin skin, but red potatoes or fingerlings can also work well.
  • For extra crispiness, soak peeled potatoes in cold water for 30 minutes before cooking to remove excess starch, then dry thoroughly.
  • Adjust garlic quantity according to taste; roasting whole smashed cloves mellows their flavor.
  • Flaky sea salt adds a lovely crunch and highlights the buttery flavor—don’t skip this garnish.
  • These potatoes can be reheated in a hot oven or air fryer to regain crispiness.
