Ingredients
- 2 cups cooked spaghetti
Serves as the base of the casserole, providing a deliciously chewy texture that absorbs the flavors of the sauce and complements the chicken. - 2 cups cooked shredded chicken
Adds protein and substance to the dish, making it hearty and satisfying. Using leftover chicken makes this dish easy and quick to prepare. - 1 cup Monterey Jack cheese, shredded
This cheese melts beautifully, creating a creamy texture and a mild flavor that blends well with other ingredients, enhancing the overall richness of the casserole. - 1 cup cream of chicken soup
Acts as a binder, giving moisture and creaminess to the casserole. It helps unify the layers while infusing a savory flavor. - 1/2 cup sour cream
Adds a tangy flavor and contributes to a rich, creamy texture. It balances the richness of the cheese and soup, preventing the dish from feeling too heavy. - 1 cup bell peppers, diced
Introduce a fresh crunch and a slight sweetness to the casserole, enhancing the overall flavor profile with their vibrant color and nutrients. - 1 teaspoon garlic powder
Brings an aromatic depth to the dish, providing a subtle yet inviting flavor that enhances the overall taste without overpowering it. - 1 teaspoon onion powder
Adds a savory note that enhances the overall flavor, creating a well-rounded taste experience in the casserole. - Salt and pepper to taste
Essential for bringing out all the flavors in the dish. Proper seasoning elevates the profile, ensuring every bite is delicious. - 1/2 cup breadcrumbs
Creates a lovely crunchy topping, adding texture contrast to the creamy casserole. They also help absorb excess moisture, keeping the dish balanced.
Directions & Preparation
Step 1: Preheat the oven to 350°F (175°C).
Preheating the oven is crucial to ensure that the casserole cooks evenly. It allows the cheese to melt beautifully and the top to brown perfectly, contributing to the overall texture and flavor.
Step 2: Cook the spaghetti according to package instructions and drain.
Cooking the spaghetti properly ensures that it retains its texture during baking. Undercooking slightly can prevent it from becoming mushy when combined with other moist ingredients.
Step 3: In a large mixing bowl, combine the cooked spaghetti, shredded chicken, bell peppers, cream of chicken soup, sour cream, garlic powder, onion powder, salt, and pepper.
Mixing these ingredients together allows the flavors to meld beautifully, ensuring that every bite has a balanced taste. This step is also where you can adjust seasoning to your preference.
Step 4: Transfer the mixture into a greased baking dish and spread evenly.
Using a greased baking dish prevents the casserole from sticking, which is especially important for easy serving. Spreading it evenly helps with consistent cooking and cheese melting.
Step 5: Sprinkle the shredded Monterey Jack cheese on top, followed by the breadcrumbs.
Layering cheese and breadcrumbs creates a deliciously cheesy and crunchy topping. The cheese becomes gooey while the breadcrumbs turn golden, offering a satisfying contrast.
Step 6: Bake in the preheated oven for 25-30 minutes or until the top is golden and bubbly.
Baking allows all the flavors to meld together and the assembly to heat through. The bubbling of the cheese indicates it's ready, while a golden top signals perfect doneness.
Step 7: Remove from the oven and let it sit for about 5 minutes before serving.
Letting the casserole rest allows the flavors to settle and makes slicing easier. It also helps prevent burns from the molten cheese when serving!
