Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat chicken thighs dry with paper towels, then season with 1/4 tsp kosher salt and 1/8 tsp black pepper.
  2. Step 2: Place chicken thighs skin-side up on a parchment-lined baking sheet. Drizzle with 1 tbsp olive oil, then top with minced garlic and chopped rosemary.
  3. Step 3: Arrange asparagus evenly around chicken, drizzle with remaining 1 tbsp olive oil, and season with remaining salt and pepper.
  4. Step 4: Roast for 25-28 minutes, flipping chicken halfway through, until chicken reaches 165°F (74°C) internally and asparagus is tender-crisp with lightly browned tips.
