Ingredients

• 1 cup sour cream
• 1 packet dry onion soup mix
• 1 cup shredded cheddar cheese

How to Make 5 Ingredient Chicken Casserole

1. Preheat the oven: Heat your oven to 375°F. Lightly grease a 9×13-inch glass casserole dish.
2. Add the chicken: Spread the diced raw chicken breast evenly across the bottom of the prepared casserole dish.
3. Make the creamy sauce: In a bowl, combine the cream of chicken soup, sour cream, and dry onion soup mix. Stir until smooth and well combined.
4. Combine: Spoon the creamy mixture over the chicken and spread it evenly so the chicken is well coated.
5. Add the cheese: Sprinkle the shredded cheddar cheese evenly over the top.
6. Bake: Bake uncovered for approximately 35–45 minutes, or until the chicken reaches an internal temperature of 165°F and the casserole is hot and bubbling.
7. Rest and serve: Let the casserole rest for about 5 minutes before serving. Spoon it over cooked rice, egg noodles, or mashed potatoes to soak up the creamy sauce.

Easy Variations

Add vegetables: Mix in frozen peas, broccoli, sliced mushrooms, or another favorite vegetable before baking.

Make it extra cheesy: Sprinkle another ½ cup of cheddar cheese over the casserole during the final 10 minutes of baking.

Use a different cheese: Monterey Jack, mozzarella, or Colby Jack can be used instead of cheddar for a slightly different flavor.

Make it milder: Reduce the amount of onion soup mix if you prefer a more delicate onion flavor.

Low-carb option: Serve the creamy chicken casserole with steamed broccoli, cauliflower, green beans, or a simple garden salad instead of rice or noodles.

What to Serve With Chicken Casserole

This creamy chicken bake pairs especially well with:

• Steamed green beans
• Roasted broccoli
• Mashed potatoes
• Buttered egg noodles
• White or brown rice
• Garden salad
• Warm dinner rolls
• Garlic bread

Helpful Cooking Tips

• Cut the chicken into similar-sized pieces so it cooks evenly.
• Avoid overcrowding the chicken in the casserole dish.
• Always check the thickest pieces with a food thermometer; chicken should reach 165°F for safe consumption.
• Let the casserole rest for a few minutes before serving so the sauce can thicken slightly.
• If adding vegetables, use vegetables that can cook in the same time as the chicken, or partially cook firmer vegetables first.

Recipe Benefits

This easy chicken casserole recipe is especially useful for busy households because it combines convenience, simple preparation, and a satisfying homemade flavor. The one-pan cooking method also reduces cleanup, while the creamy sauce helps keep the chicken moist and flavorful.

Adding vegetables can increase the meal’s variety and provide additional fiber and nutrients, while serving the casserole with rice, potatoes, or noodles makes it a filling family dinner.
