Cooking Time & Tips For Creamy Cheesy Spaghetti Chicken Casserole
When it comes to preparing this delicious casserole, there’s a difference between quick and slow preparation. Quick preparation involves using pre-cooked chicken and pre-chopped vegetables to minimize hands-on time, making it a breeze to whip up this comforting meal during busy weeknights. On the other hand, if you have a bit more time, slow preparation can involve poaching your chicken and freshly chopping your vegetables, ensuring maximum flavor and freshness.

- Use cooked chicken: Rotisserie chicken works wonderfully and saves you time in preparing the meal.

- Garnish: Consider garnishing with fresh herbs, like parsley or cilantro, for added color and freshness.
Step-by-Step Directions

Preheat the oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish, ensuring an easy release for the finished casserole.
In a large bowl, mix together the cream of mushroom soup, cream of chicken soup, sour cream, garlic powder, salt, black pepper, and paprika. Stir until smooth, creating a base that’s rich and flavorful.
Add the shredded chicken, drained diced tomatoes, green and red bell peppers, and chopped onion. With each ingredient, the mixture becomes more vibrant and aromatic. Stir to combine, ensuring every ingredient is well incorporated.
Carefully fold in the cooked spaghetti, mixing until fully coated with the creamy sauce. This step is crucial to ensure each strand of pasta is enveloped in deliciousness.
Transfer the mixture to the greased baking dish and spread evenly. Be generous, making sure every corner is filled. Top with the remaining shredded cheese, allowing it to melt beautifully during baking.
Bake uncovered for 30-35 minutes, or until the cheese is bubbly and golden on top. The enticing aroma wafting through your kitchen will be irresistible!
