Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C).
  2. Step 2: Pat 4 bone-in, skin-on chicken thighs (about 1.5 lbs) dry with paper towels, then rub with 2 tablespoons olive oil, 1 tablespoon fresh rosemary, 2 minced garlic cloves, 1 teaspoon salt, and 1/2 teaspoon black pepper.
  3. Step 3: Arrange the chicken thighs skin-side up in a single layer on a baking sheet lined with parchment paper.
  4. Step 4: Place 1 bunch asparagus (about 12 oz, trimmed) around the chicken on the baking sheet.
  5. Step 5: Drizzle the asparagus with 1 tablespoon butter and season with a pinch of salt and pepper.
  6. Step 6: Roast in the preheated oven for 35-40 minutes, or until chicken reaches an internal temperature of 165°F (74°C) and the skin is crispy, flipping the chicken halfway through.
  7. Step 7: Check that the asparagus is tender-crisp by piercing with a fork; if not, continue roasting for 5 more minutes.
