Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Slice 2 large potatoes into 1/4-inch thick medallions using a mandoline or sharp knife.
  2. Step 2: Toss potato medallions with 1 tbsp olive oil, 1 tsp chopped fresh rosemary, 1/4 tsp salt, and 1/8 tsp black pepper on a parchment-lined baking sheet.
  3. Step 3: Roast for 25 minutes, flipping halfway, until potatoes are golden brown and crispy around the edges.
  4. Step 4: While potatoes roast, whisk 1/4 cup heavy cream, 1 tbsp lemon juice from 1/2 lemon, 1 tbsp chopped fresh dill, 1/4 tsp salt, and 1 tbsp water in a small saucepan. Simmer over low heat for 3 minutes until slightly thickened.
  5. Step 5: Remove potatoes from oven, sprinkle with 2 tbsp grated parmesan, and serve immediately with warm lemon-dill sauce drizzled over the top.
