Preheat oven to 375 degrees F. Coat a 9x13 baking dish with nonstick spray.
Place the chicken strips in the bottom of the casserole dish in a single layer. Season with the garlic powder, onion powder, dried oregano, paprika, and pepper.
In a mixing bowl, add in the uncooked white rice, cream of chicken soup, cream of celery soup, and chicken broth. Stir everything to combine until incorporated. Pour mixture over the chicken in an even layer.
Sprinkle the dry onion soup mix over the top.
Cover the baking dish tightly with foil.
Bake in the preheated oven for 1 hour or until the chicken is cooked through at 165F. While it’s baking, no peeking! The steam is essential for keeping the chicken moist.
Fluff the rice with a fork and enjoy with the chicken.
