12 oz spaghetti
2 cups cooked, shredded chicken
2 tablespoons butter
1 small onion, diced
1 small green bell pepper, diced
2 cloves garlic, minced
1 can (10.5 oz) cream of chicken soup
1 can (10.5 oz) cream of mushroom soup
1 can (10 oz) Rotel tomatoes, drained
1 cup chicken broth
1 teaspoon Italian seasoning
1/2 teaspoon paprika
1/2 teaspoon salt
1/2 teaspoon black pepper
2 cups shredded cheddar cheese
1/2 cup shredded mozzarella cheese
1/4 cup grated Parmesan cheese

Directions

Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish.

Cook the spaghetti according to package instructions until al dente. Drain and set aside.

In a large skillet, melt the butter over medium heat. Add the diced onion, green bell pepper, and minced garlic. Sauté for about 3 to 4 minutes until the vegetables soften and become fragrant.

Stir in the cream of chicken soup, cream of mushroom soup, Rotel tomatoes, and chicken broth. Mix well until everything is combined.

Add the Italian seasoning, paprika, salt, and black pepper. Stir to distribute the seasonings evenly throughout the sauce.

Reduce the heat to low and add the shredded chicken, stirring until the chicken is fully coated in the creamy sauce.

Add the cooked spaghetti to the skillet and mix until the pasta is evenly coated with the sauce.

Transfer the mixture to the prepared baking dish. Sprinkle the shredded cheddar, mozzarella, and grated Parmesan cheese evenly over the top.

Bake uncovered for 25 to 30 minutes, or until the cheese is melted, bubbly, and lightly golden.

Remove from the oven and let the casserole sit for about 5 minutes before serving.

Variations

You can easily customize this chicken spaghetti to match your taste preferences.

For a spicier version, add diced jalapeños or use hot Rotel tomatoes. This adds a bit more heat and depth to the sauce.

If you prefer a lighter dish, substitute half of the cheddar cheese with Monterey Jack or reduce the amount of cheese slightly.

Using rotisserie chicken is a great time-saving option that also adds extra flavor to the dish.

You can also add vegetables such as mushrooms, spinach, or broccoli to increase the nutritional value and add texture.

For a different cheese profile, try using Colby Jack or Pepper Jack cheese in place of the cheddar.

Storage/Reheating

Store leftover chicken spaghetti in an airtight container in the refrigerator for up to 4 days.

To reheat, place a portion in the microwave and heat in 30–45 second intervals, stirring occasionally until warmed through.

For reheating larger portions, place the casserole in an oven-safe dish, cover with foil, and heat at 325°F (165°C) for about 15–20 minutes.

If the pasta appears dry during reheating, add a small splash of chicken broth or milk to restore its creamy texture.

This dish can also be frozen. Allow the casserole to cool completely, then wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
