Make the Marinade: In a bowl, whisk together olive oil, lemon juice, lemon zest, garlic, thyme, salt, pepper, poultry seasoning and paprika.
Season the Chicken: Add all the chicken pieces to the marinade and toss to coat. Let it sit for 15-20 minutes while the oven preheats.
Arrange on the Pan: Place the chicken on a sheet pan or baking dish, breasts in the center and drumsticks around the edges. Pour any remaining marinade over the top. Add lemon slices if you want extra brightness.
Bake: Bake at 425°F for 45-55 minutes. Drumsticks usually finish around 40-45 minutes, breasts usually finish around 50-55 minutes. If the drumsticks finish early, remove them and let the breasts continue.
Optional Broil: Broil for 2 minutes for golden, crisp edges.
Rest and Serve: Let the chicken rest 5-10 minutes before slicing or serving.
