A nostalgic, one-pan comfort food classic featuring creamy rice and tender chicken. This version ensures juicy results with a tight foil seal and savory onion soup seasoning.
Heat the oven to 350˚F and set a rack in the middle so the casserole cooks evenly. Give a 9x13-inch baking dish a thorough coating of cooking spray, especially the corners.
In the dish, whisk the cream of chicken soup, cream of celery soup, and water until smooth. Stir in the quick-cooking rice, frozen peas and carrots, and half of the onion soup mix until evenly distributed.
Season and Nestle the Chicken
Season the chicken breasts with kosher salt and black pepper, then nestle them into the rice mixture. Sprinkle the remaining onion soup mix over the top to form a savory crust.
Cover the dish with aluminum foil and seal it tightly all the way around, pressing the edges firmly to trap steam.
Bake, Then Rest Before Fluffing
Bake for 50 to 60 minutes, keeping the foil on the entire time. The chicken is ready when an instant-read thermometer hits 160°F in the thickest part.
Let the casserole rest for 5 minutes while still covered. Uncover, fluff the rice with a fork, and scatter fresh chives over the top if desired.
Notes
Preparation Tip: Pound the chicken breasts to an even thickness so they finish cooking at the same time and remain juicy.Cooking Tip: Do not lift the foil during the baking process. Trapped steam is essential for hydrating the rice and keeping the chicken tender.Storage Tip: Leftovers keep well in the refrigerator for up to 3 days. Reheat with a small splash of water stirred into the rice to maintain moisture.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
