How to Make Chicken Spaghetti Bake
Step 1: Cook the Spaghetti
Bring a large pot of salted water to a boil. Cook the spaghetti according to the package instructions until al dente.
Drain the pasta and set it aside. Avoid overcooking the spaghetti because it will continue cooking in the oven.
Step 2: Prepare the Vegetables
In a large skillet, melt the butter over medium heat. Add the diced onion and bell pepper, then cook for about 4 to 5 minutes until softened.
Stir in the minced garlic and cook for another minute until fragrant.
Step 3: Make the Creamy Sauce
Add the cream of mushroom soup, cream of chicken soup, sour cream, diced tomatoes with green chilies, Italian seasoning, salt, and black pepper to the skillet.
Mix everything together until the sauce becomes smooth and creamy.
Step 4: Add the Chicken and Pasta
Stir the cooked chicken into the sauce mixture. Then add the cooked spaghetti and gently toss everything together until evenly coated.
Mix in 1 1/2 cups of shredded cheddar cheese and half of the Parmesan cheese for extra richness.
Step 5: Assemble the Casserole
Preheat your oven to 350°F (175°C).
Transfer the spaghetti mixture into a greased baking dish and spread it evenly.
Sprinkle the remaining cheddar cheese and Parmesan cheese on top.
Step 6: Bake Until Golden
Bake the casserole uncovered for about 25 to 30 minutes, or until the cheese is melted and bubbly.
For an extra golden top, broil the casserole for 2 to 3 minutes at the end of baking.
Step 7: Garnish and Serve
Remove the casserole from the oven and let it rest for a few minutes before serving.
Garnish with fresh parsley for a burst of color and freshness.
Tips for the Best Chicken Spaghetti Bake
Using rotisserie chicken saves time and adds extra flavor to the dish. If you prefer a lighter version, you can substitute Greek yogurt for sour cream.
Freshly shredded cheese melts better than pre-packaged cheese because it contains fewer anti-caking agents.
If the casserole seems too thick before baking, you can add a splash of chicken broth or milk to loosen the sauce slightly.
Delicious Variations
One of the best things about this recipe is how easy it is to customize. Here are some popular variations:
Spicy Chicken Spaghetti Bake
Add jalapeños, cayenne pepper, or extra diced green chilies for more heat.
Vegetable Chicken Spaghetti Bake
Mix in mushrooms, spinach, broccoli, or zucchini for additional nutrition.
Extra Cheesy Version
Use a blend of cheddar, mozzarella, Monterey Jack, and Parmesan cheese for maximum cheesiness.
Bacon Chicken Spaghetti Bake
Add cooked crumbled bacon for smoky flavor and extra richness.
How to Store and Reheat
Store leftovers in an airtight container in the refrigerator for up to 4 days.
To reheat, place a portion in the microwave or warm it in the oven at 350°F until heated through.
This casserole also freezes very well. Simply wrap it tightly and freeze for up to 3 months.
