Ingredients
- 3 cups cooked chicken breast, shredded
- 12 oz spaghetti, cooked and drained
- 1 can (10.5 oz) cream of mushroom soup
- 1 can (10.5 oz) cream of chicken soup
- 1 can (10 oz) diced tomatoes with green chilies, drained
- 1 cup chopped green bell pepper
- 1 cup chopped red bell pepper
- 1/2 cup chopped onion
- 2 cups shredded cheddar cheese, divided
- 1/2 cup sour cream
- 1 tsp garlic powder
- 1 tsp black pepper
- 1/2 tsp salt
- 1/2 tsp paprika
Instructions
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This step is essential, as it ensures that your casserole will cook evenly and efficiently, resulting in perfectly melted cheese and a bubbling, golden-brown topping.
Step 2: Create the Creamy Base
In a large mixing bowl, combine the cream of mushroom soup, cream of chicken soup, and sour cream. Add the garlic powder, black pepper, salt, and paprika into the mix, stirring well to ensure all ingredients are fully incorporated. This creamy base is what gives your casserole its rich flavor and comforting texture.
Step 3: Mix in the Hearty Ingredients
Next, fold in the cooked shredded chicken, drained diced tomatoes with green chilies, and the chopped bell peppers and onion into the creamy mixture. Add 1 cup of the shredded cheddar cheese, mixing gently to ensure that everything is evenly distributed and well-coated in the sauce.
Step 4: Combine with Spaghetti
Now, carefully add the cooked and drained spaghetti to the bowl. Gently fold it into the creamy mixture until all the noodles are thoroughly coated. This step is essential to ensuring that every bite of casserole is filled with the delightful combination of flavors. Transfer this well-mixed mixture to your greased baking dish, spreading it out evenly.
Step 5: Top and Bake
Sprinkle the remaining 1 cup of shredded cheddar cheese over the top of the casserole. This will create a delicious, cheesy crust as it bakes. Place the baking dish in the preheated oven and bake uncovered for about 30-35 minutes, or until the casserole is bubbly and the cheese has melted and turned a beautiful golden color. For an extra crispy cheese topping, consider broiling for 2-3 minutes at the end.
