This 4-ingredient oven chicken is the kind of weeknight dinner that saves the day when the freezer is full but the fridge looks bare. Using frozen chicken breast chunks right in the casserole dish keeps prep almost effortless, and the simple ingredient list makes it easy to throw together after work without a second thought. It has that practical, comforting appeal of classic dump-and-bake dinners, but the end result still feels like a real homemade meal worth putting on the table.
Serve this chicken over rice, buttered noodles, or mashed potatoes to soak up the savory sauce, and add a simple green vegetable like roasted broccoli, green beans, or a side salad to round things out. If you want an even easier dinner, pair it with warm dinner rolls or garlic toast and let the casserole do most of the heavy lifting.
4-Ingredient Oven Chicken
Servings: 4 to 6
Ingredients
2 pounds frozen chicken breast chunks
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch glass casserole dish if desired for easier cleanup.
2. Spread the frozen chicken breast chunks evenly in the casserole dish.
3. In a medium bowl, stir together the condensed cream of chicken soup, dry onion soup mix, and sour cream until well combined.
4. Spoon the sauce over the frozen chicken and spread it as evenly as possible to coat the pieces.
5. Cover the dish tightly with foil and bake for 45 minutes. Remove the foil, stir gently if needed, and continue baking for 20 to 30 minutes more, or until the chicken is cooked through and reaches 165°F in the center.
6. Let the casserole rest for 5 minutes before serving so the sauce can settle slightly.
Variations & Tips
Add vegetables: For a fuller one-dish meal, add frozen broccoli florets or drained canned mushrooms during the last 20 minutes of baking. This is one of my favorite ways to stretch the dish on a busy weeknight without making another side.
Make it cheesier: Sprinkle shredded mozzarella or cheddar over the top for the last 10 minutes of baking if your family likes a richer casserole. The melted cheese adds a little extra comfort-food feel and helps the top brown nicely.
Use a thermometer: Since frozen chicken pieces can vary in size, checking for 165°F in the thickest pieces is the easiest way to avoid undercooking or drying it out. If the sauce starts browning too quickly, loosely tent the dish with foil near the end.
Serve it different ways: This chicken also works well spooned over baked potatoes, toast, or even egg noodles. If you have leftovers, they reheat nicely for lunch the next day, which makes this recipe especially useful during a packed workweek.
