Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 2 lbs halved baby potatoes with 2 tbsp olive oil, 1 1/2 tsp salt, and 1/2 tsp black pepper ensuring even coating.
  2. Step 2: Spread the potatoes cut side down on a baking sheet in a single layer. Roast for 25 minutes until the edges are golden and crispy.
  3. Step 3: While potatoes roast, melt 4 tbsp unsalted butter in a small saucepan over medium heat. Add 4 minced garlic cloves and 2 tbsp chopped fresh rosemary, cooking for 2 minutes until fragrant but not browned. Remove from heat and stir in 1 tbsp lemon zest and 2 tbsp lemon juice.
  4. Step 4: Remove the potatoes from the oven and immediately drizzle the garlic rosemary butter over them, tossing gently to coat.
  5. Step 5: Return potatoes to the oven for an additional 5 minutes to absorb flavors. Remove, garnish with 2 tbsp chopped fresh parsley, and serve warm.
