Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat chicken thighs dry with paper towels, then season with 1/2 teaspoon sea salt, 1/4 teaspoon black pepper, 1 teaspoon chopped rosemary, and 2 minced garlic cloves. Rub 1 tablespoon olive oil over the thighs.
  2. Step 2: Place chicken thighs skin-side up in a single layer on a parchment-lined baking sheet. Arrange 12 ounces trimmed asparagus around the chicken. Drizzle asparagus with 1/2 tablespoon olive oil, then season with 1/4 teaspoon sea salt and 1/4 teaspoon black pepper.
  3. Step 3: Roast for 25-30 minutes until chicken reaches an internal temperature of 165°F (74°C) and asparagus is tender-crisp with slightly browned edges.
