Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat 16 oz chicken breasts dry with paper towels and season evenly with 1/2 tsp salt and 1/4 tsp black pepper.
  2. Step 2: In a small bowl, whisk together 2 tbsp olive oil, 3 minced garlic cloves, 1 tsp lemon zest, 1/2 tsp lemon juice, 1 tsp dried thyme, and 1/2 tsp dried rosemary until fully combined.
  3. Step 3: Place chicken breasts in a single layer in a baking dish, brush with half the herb-oil mixture, and bake at 400°F for 20 minutes until golden on top.
  4. Step 4: Add 1 lb trimmed asparagus to the baking dish, spoon the remaining herb-oil mixture over everything, and bake for 15-18 minutes more until chicken reaches 165°F internally and asparagus is tender-crisp with slightly charred edges.
  5. Step 5: Gently stir in 1/4 cup halved pitted green olives, let rest for 5 minutes to allow flavors to meld, and serve immediately.
