Preheat and prep: Heat oven to 425°F (220°C). Pat chicken very dry with paper towels. Dry skin = better browning.
Mix the flavor base: In a bowl, combine melted butter, olive oil, garlic, rosemary, thyme, parsley, lemon zest, lemon juice, salt, pepper, and red pepper flakes (if using).
Stir in Parmesan if you want a richer crust.
Season the chicken: Place chicken in a baking dish or oven-safe skillet. Spoon the garlic-herb mixture over and under the skin when possible. Coat evenly.
Add moisture: Pour chicken broth around (not over) the chicken to keep the pan juicy without washing off the seasoning.
Add veggies (optional): Toss zucchini rounds, broccoli florets, or asparagus with a little olive oil, salt, and pepper.
Arrange around the chicken in the same pan.
Bake: Roast for 30–40 minutes for bone-in thighs (20–28 minutes for boneless), until the internal temperature reaches 165°F (74°C) in the thickest part.
Broil for crispiness: If the skin needs extra color, switch to broil for 2–3 minutes. Watch closely.
Rest and baste: Let the chicken rest 5–10 minutes. Spoon pan juices over the top for more flavor.
Finish and serve: Sprinkle fresh parsley and a squeeze of lemon over everything.
Serve with the pan sauce.
