Ingredients
2 pounds raw chicken breast, diced
The chicken is the hearty protein at the center of this casserole. Cutting the breasts into bite-size pieces helps them cook more evenly and allows the creamy sauce to coat every piece.
1 (10.5-ounce) can cream of chicken soup
This provides the casserole’s creamy base while adding savory chicken flavor. It also helps create the rich sauce that makes this dish so good served over rice, noodles, or mashed potatoes.
1 cup sour cream
Sour cream adds creaminess and a subtle tang that balances the richness of the soup. It helps give the finished casserole its smooth, comforting texture.
1 packet dry onion soup mix
This is the shortcut ingredient that brings plenty of savory onion flavor without requiring you to chop and sauté onions. It seasons the creamy sauce throughout.
1 cup shredded cheddar cheese
Cheddar melts over the casserole into a golden, cheesy topping. Its sharp flavor pairs beautifully with the creamy chicken and onion-seasoned sauce.
How to Make 5-Ingredient Oven Chicken
1. Prepare the oven and baking dish
Preheat your oven to 375°F. Lightly grease a 9×13-inch glass casserole dish to make serving and cleanup easier.
2. Add the chicken
Place the raw diced chicken breast directly into the prepared casserole dish. Spread the pieces into an even layer so they cook as consistently as possible.
3. Make the creamy sauce
In a medium bowl, combine the cream of chicken soup, sour cream, and dry onion soup mix. Stir until everything is thoroughly blended and the mixture is smooth.
4. Coat the chicken
Spoon the creamy mixture over the chicken. Spread it gently across the surface so the chicken is well covered.
Sprinkle the shredded cheddar cheese evenly over the top.
5. Bake
Place the uncovered casserole in the preheated oven and bake for approximately 35 to 45 minutes, or until the chicken is fully cooked and the sauce is hot and bubbling.
Because chicken pieces can vary in size, use an instant-read thermometer to check the thickest pieces. The chicken should reach an internal temperature of 165°F.
6. Rest and serve
Allow the casserole to rest for about 5 minutes before serving. This gives the creamy sauce a moment to settle while keeping the chicken juicy and tender.
Spoon generous portions over your favorite starch and enjoy.

Pro Tips for Perfect Oven-Baked Chicken
Cut the chicken evenly. Try to keep the pieces close in size so smaller pieces don’t overcook while larger pieces finish cooking.
Don’t skip the temperature check. Since the chicken starts raw, always verify that the thickest pieces reach 165°F before serving.
Avoid overbaking. Once the chicken reaches a safe temperature, remove the casserole from the oven. Chicken breast can become dry if cooked significantly longer than necessary.
Spread the sauce evenly. Making sure the creamy mixture covers the chicken helps prevent exposed pieces from drying out.
Let it rest. A brief five-minute rest allows the sauce to settle and makes the casserole easier to serve.
Watch the seasoning. Dry onion soup mix already contains salt and seasoning, so additional salt may not be necessary.
Easy Variations
Want to turn this simple casserole into something different? Try one of these ideas:
Add vegetables: Stir in frozen peas, chopped broccoli, sliced mushrooms, or another favorite quick-cooking vegetable before adding the cheese.
Change the cheese: Swap cheddar for mozzarella, Monterey Jack, Colby, or a cheddar blend.
Make it extra cheesy: Sprinkle another ½ cup of cheese over the casserole during the final 10 minutes of baking.
Add a little crunch: Top the finished casserole with toasted breadcrumbs or crushed buttery crackers for a crispy contrast.
Make it a complete one-dish meal: Add vegetables directly to the casserole and serve it alongside a simple salad.
What to Serve With Creamy Oven Chicken
This casserole has a wonderfully rich sauce, so it is especially delicious with something that can soak it up.
Serve it over:
– Steamed white or brown rice
– Buttered egg noodles
– Creamy mashed potatoes
– Fluffy biscuits
– Garlic bread
– Warm dinner rolls
For vegetables, try steamed green beans, roasted broccoli, glazed carrots, or a crisp garden salad. The fresh vegetables add a nice contrast to the creamy chicken.
Frequently Asked Questions
Can I use chicken thighs instead of chicken breast?
Yes. Boneless, skinless chicken thighs can be used, although the cooking time may vary depending on how large the pieces are. Always check that the chicken reaches 165°F internally.
Can I add vegetables?
Absolutely. Frozen peas, broccoli, and sliced mushrooms are easy additions. Avoid overcrowding the dish, however, because adding a large amount of vegetables can affect cooking time.
Can I prepare this casserole ahead of time?
You can assemble the ingredients ahead and refrigerate the unbaked casserole, provided it is kept properly refrigerated. Since the recipe starts with raw chicken, don’t leave the assembled dish sitting at room temperature.
What is the best way to reheat leftovers?
Reheat individual portions gently in the microwave or warm larger portions covered in the oven until heated through. Avoid excessive reheating so the chicken stays tender.
