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). 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 3–4 minutes until softened and fragrant.
Stir in the cream of chicken soup, cream of mushroom soup, drained Rotel tomatoes, and chicken broth. Mix until smooth and well combined.
Add Italian seasoning, paprika, salt, and black pepper. Stir to incorporate the seasonings evenly.
Reduce the heat to low and add the shredded chicken. Stir until the chicken is fully coated in the sauce.
Add the cooked spaghetti to the skillet and toss until evenly coated with the creamy mixture.
Transfer the mixture to the prepared baking dish and spread it evenly.
Sprinkle the cheddar, mozzarella, and Parmesan cheese evenly over the top.
Bake uncovered for 25–30 minutes, or until the cheese is melted, bubbly, and lightly golden.
Let the casserole rest for 5 minutes before serving to allow it to set.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days.

To reheat in the microwave, cover loosely and heat in 30–60 second intervals, stirring if needed, until warmed through.

To reheat in the oven, cover the dish with foil and bake at 325°F until heated thoroughly. Add a splash of chicken broth if the pasta seems dry.

For freezing, allow the casserole to cool completely, wrap tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

FAQs

Can I use rotisserie chicken?

Yes, rotisserie chicken works perfectly and saves time. Simply shred and measure out two cups.

Can I make this recipe ahead of time?

Yes. Assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking.

Can I freeze chicken spaghetti before baking?

Yes, you can assemble it, wrap tightly, and freeze. Bake from thawed for best results.

What can I use instead of cream of mushroom soup?

You can substitute with another can of cream of chicken soup or use cream of celery soup.

How do I prevent the pasta from becoming mushy?

Cook the spaghetti just until al dente so it finishes cooking in the oven without over-softening.

Can I make this dish without baking it?

Yes, you can serve it directly from the stovetop once everything is mixed and heated, though baking adds a delicious cheesy crust.

Is this recipe spicy?

It has mild heat from the Rotel tomatoes. For less spice, use mild Rotel or regular diced tomatoes.

Can I add more vegetables?

Absolutely. Bell peppers, mushrooms, peas, or spinach are great additions.
