Instructions

Step 1: Preheat oven to 400°F (200°C). Place 1.5 pounds boneless skinless chicken thighs in a single layer in a large oven-safe skillet. Drizzle with 1 tablespoon olive oil and season with 1/2 teaspoon kosher salt and 1/4 teaspoon black pepper. Scatter 2 teaspoons fresh rosemary over the chicken.
Step 2: Roast for 20 minutes.
Step 3: Meanwhile, trim and cut 1 pound asparagus into 2-inch pieces. Toss with 1 tablespoon olive oil, 1/4 teaspoon kosher salt, and 1/4 teaspoon black pepper. Add to the skillet around the chicken. Add 3 minced garlic cloves to the pan.
Step 4: Roast for an additional 10-15 minutes until chicken reaches 165°F internally and asparagus is tender with slight char.
