Ingredients
- 12 oz spaghetti, broken into thirds
- 3 cups cooked chicken, shredded (rotisserie or poached)
- 1 tbsp olive oil
- 1 small onion, finely chopped
- 1 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) diced tomatoes with green chilies, drained
- 1 cup chicken broth
- 2 cups shredded cheddar cheese, divided
- 1 cup shredded mozzarella cheese
- 1 tsp salt
- ½ tsp black pepper
- ½ tsp paprika
- ½ tsp garlic powder
- Optional garnishes:
- Fresh parsley, chopped
- Crushed red pepper flakes
- Extra cheese on top
Instructions
1. Boil a large pot of salted water. Cook spaghetti until just al dente, about 8 minutes. Drain and set aside.
2. Heat olive oil in a skillet over medium heat. Add onion and bell pepper; cook for 4–5 minutes until softened. Add garlic and cook for 30 seconds, then remove from heat.
3. In a large mixing bowl, combine cream of chicken soup, cream of mushroom soup, diced tomatoes with green chilies, and chicken broth. Add salt, black pepper, paprika, and garlic powder.
4. Stir in shredded chicken, sautéed vegetables, 1½ cups cheddar cheese, mozzarella cheese, and cooked spaghetti. Mix until well combined.
5. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish and spread the spaghetti mixture evenly. Top with remaining ½ cup cheddar cheese. Cover with foil.
6. Bake for 25 minutes, covered. Remove foil and bake an additional 10–15 minutes until bubbly and golden.
7. Let rest for 5 minutes before serving. Garnish with parsley or red pepper flakes if desired.
Notes
Use rotisserie chicken for added flavor and convenience.
Break spaghetti into thirds to make it easier to mix and serve.
Add extra veggies like mushrooms, spinach, or corn for more variety.
Add jalapeños or hot sauce for a spicier version.
Make ahead: assemble up to 24 hours in advance, refrigerate, and bake when ready.
