Ingredients List
- 8 ounces spaghetti
- 2 cups cooked chicken, shredded (about 2 chicken breasts)
- 1 cup cheddar cheese, shredded
- 1 cup cream of chicken soup
- 1 cup diced tomatoes with green chilies (canned)
- 1/2 cup sour cream
- 1/2 cup onion, finely chopped
- 2 cloves garlic, minced
- 1 teaspoon Italian seasoning
- 1 teaspoon salt (to taste)
- 1/2 teaspoon black pepper
- 1/2 teaspoon paprika (optional for extra flavor)
- 1 tablespoon olive oil
- 1/2 cup additional cheese for topping

Step-by-Step Instructions
Step 1: Prepare the Pasta
Begin by cooking the spaghetti according to the package instructions. Bring a large pot of salted water to a boil, then add the spaghetti. Cook it until al dente, usually around 8-10 minutes. Drain the pasta and set it aside.
Step 2: Sauté Aromatics
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and minced garlic, sautéing until the onions turn translucent and fragrant, about 4-5 minutes.
Step 3: Combine Ingredients
In a large mixing bowl, combine the cooked chicken, sautéed onions and garlic, cream of chicken soup, diced tomatoes with green chilies, sour cream, Italian seasoning, salt, pepper, and paprika. Stir until well mixed.
Step 4: Add the Spaghetti
Gently fold the drained spaghetti into the chicken and sauce mixture. Ensure the pasta is well-coated with the creamy sauce.
Step 5: Prepare for Baking
Preheat your oven to 350°F (175°C). Transfer the spaghetti mixture into a greased 9×13-inch baking dish. Spread it evenly, ensuring it’s nicely packed.
Step 6: Cheese It Up
Sprinkle the shredded cheddar cheese evenly over the top of the bake. If you desire extra cheesiness, feel free to add the additional cheese specified earlier.
Step 7: Bake
Place the baking dish in the preheated oven and bake for approximately 25-30 minutes, or until the cheese is bubbly and lightly golden on top.
Step 8: Cool and Serve
Once done, remove the dish from the oven and let it cool for about 5-10 minutes before serving. This helps the sauce thicken slightly and makes serving easier.
Pro Tips for Perfect Results
Cook Chicken in Advance: Use leftover rotisserie chicken for quick assembly, or cook chicken breasts ahead of time to save on prep.
Test Cheese before Baking: Mix in a portion of cheese with the chicken mixture to ensure creamy, cheesy goodness throughout the bake.
Vary the Cheese: Experiment with different cheese types like Monterey Jack or Pepper Jack for a twist in flavor.
Add Veggies: Incorporate vegetables like bell peppers, spinach, or broccoli for added nutrition and flavor; make sure to sauté until tender before adding them to the mixture.
Cover While Baking: If you want to avoid over-browning the cheese, cover the dish with aluminum foil for the first 20 minutes of baking.
Variations and Substitutions
- Pasta Alternatives: Swap spaghetti for different pasta shapes such as penne or fusilli. Whole wheat or gluten-free options are also great for dietary preferences.
- Sauce Variations: Use homemade Alfredo sauce instead of cream of chicken soup for a richer, creamier texture.
- Different Proteins: Substitute chicken with turkey or shredded beef for a different protein profile that still delivers the comfort.
Storage and Reheating Tips
To store Chicken Spaghetti Bake, allow it to cool completely, then cover it tightly with plastic wrap or aluminum foil and refrigerate. It will keep well in the fridge for up to 3 days or can be frozen for up to 2 months. To reheat, preheat your oven to 350°F (175°C), cover with foil, and heat for about 25-30 minutes (or until heated through); for microwave reheating, place a serving in a microwave-safe dish and heat in 1-minute increments until warm.
