Equipment

  • sharp knife
  • Pastry brush
  • Baking dish
  • Small microwave-safe bowl

Ingredients

  • 10-12 medium to large yellow potatoes
  • 4 tablespoons butter melted
  • 1-2 tablespoons minced garlic
  • 1 tablespoon dried rosemary or thyme
  • Avocado oil spray
  • Sea salt to taste
  • Fresh parsley chopped (optional)

Instructions

  • Preheat oven to 425°F (220°C).
  • Wash and dry the potatoes. Slice thinly, about 1 cm apart, without cutting all the way through.
  • In a small bowl, combine melted butter, minced garlic, and rosemary.
  • Spray your baking dish and arrange the potatoes in a single layer. Brush generously with the garlic butter mixture, getting between each slice.
  • Roast for 45–55 minutes, brushing with butter halfway through, until golden and crisp.
  • Sprinkle with sea salt and fresh parsley before serving.

Notes

  • If you cut all the way through a potato, don’t stress — just nestle the pieces together in the dish. They’ll bake up beautifully.
  • For extra crispiness, give the potatoes one last brush of butter during the final 10 minutes of baking.
  • A sprinkle of flaky sea salt right before serving adds texture and enhances the buttery flavor.
