Dump-and-bake chicken combines chicken, rice, and a creamy sauce in one pan with zero precooking needed. This protein-packed family dinner is the ultimate weeknight shortcut that still delivers comfort food satisfaction.
Preheat oven to 375°F. Grease a large 9x13-inch baking dish with nonstick spray.
In the baking dish, evenly spread uncooked rice and frozen mixed vegetables.
In a bowl, whisk together chicken broth, cream of chicken soup, garlic powder, thyme, salt, and pepper until smooth, then pour over rice and vegetables.
Arrange chicken breasts on top of the mixture, pressing gently to partially submerge; spoon some of the liquid over the chicken to keep it moist.
Cover tightly with foil and bake for 45 minutes, then remove foil and bake an additional 20–25 minutes or until chicken is cooked through (internal temp 165°F) and rice is tender.
Let rest for 10 minutes before serving to allow sauce to set.
