Key Ingredients and Substitutions

The Pasta Base

The traditional choice is regular spaghetti, but you can experiment with other pasta shapes. For a healthier option, try whole wheat spaghetti or gluten-free pasta. Just remember to cook it slightly al dente as it will continue cooking in the oven.

The Protein

While this recipe calls for chicken breast, you can use:

• Rotisserie chicken for convenience
• Chicken thighs for more flavor
• Turkey as a lighter alternative
• Canned chicken in a pinch

The Creamy Sauce

The combination of cream soups creates the perfect consistency, but you can make substitutions:

• Replace cream soups with a homemade bechamel sauce
• Use Greek yogurt instead of sour cream
•   Try using Monterey Jack, Colby, or Pepper Jack for different flavors.  

  How to Make Chicken Spaghetti Casserole (Detailed Steps)

 

Step 1: Preparation (25 minutes)

1. Position your oven rack in the middle and preheat to 350°F (175°C)

2.  Add spaghetti to the boiling water and cook for 2 minutes less than package directions.  
3.   Before draining the pasta, set aside 1 cup of the cooking water.

2. Add butter and let it melt completely
3. Add diced onions and bell peppers, sautéing for 4-5 minutes

2. Combine in a large bowl:
   • Cooked spaghetti
   • Shredded chicken
   • Sautéed vegetables
   • Creamy sauce mixture
3. Fold ingredients together gently to avoid breaking pasta
4. Transfer to baking dish, ensuring even distribution

Step 6: Baking (35-40 minutes)

1.  Cover the dish with foil and bake for the first 20 minutes
2. Remove the foil and bake for an additional 15-20 minutes, until golden and bubbly.
   • Edges are bubbling
