Set your oven to 375°F (190°C). Chop zucchini, bell peppers, onion, and garlic, then add them to the baking dish with uncooked rice.

Add flavor by mixing in chicken broth, herbs, garlic powder, crushed red pepper. Stir everything together until evenly combined.

Season the chicken thighs with garlic powder. Place the chicken on top of the rice and veggie mixture.

Cover and bake until the rice is tender and the chicken is fully cooked. Then uncover and bake a little longer to let the chicken brown on top. (Nyehn, 2025).
