- 2 cups Monterey Jack cheese, shredded
- 1 cup sharp cheddar cheese, shredded
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 red bell pepper, diced
- 1 can (10.5 oz) cream of chicken soup
- 1 cup sour cream
- 1/2 cup chicken broth
- 1 teaspoon Italian seasoning
- 1/2 teaspoon paprika

- 2 tablespoons olive oil

Step-by-Step Instructions
Step 1: Cook the Pasta
Bring a large pot of salted water to boil. Cook the spaghetti according to package directions until al dente. Drain well and set aside.
Step 2: Sauté Vegetables
While pasta cooks, heat olive oil in a large skillet over medium heat. Add chopped onion and red bell pepper, cooking until softened (about 5 minutes). Add minced garlic and cook for another minute until fragrant.
Step 3: Create the Sauce
Reduce heat to low and stir in cream of chicken soup, sour cream, and chicken broth. Mix until smooth and creamy. Add Italian seasoning, paprika, salt, and pepper. Stir in the cooked chicken.
Step 4: Combine Everything
Add the cooked spaghetti to the sauce mixture, tossing gently to coat every strand. Stir in 1 1/2 cups of the Monterey Jack cheese and all of the cheddar cheese until well combined.
Step 5: Bake to Perfection
Transfer the mixture to a greased 9×13 inch baking dish. Top with remaining 1/2 cup Monterey Jack cheese. Bake at 375°F for 20-25 minutes until bubbly and golden brown on top.
Step 6: Serve and Enjoy
Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley if desired. Serve warm with a side salad or steamed vegetables.
Expert Tips for Perfect Monterey Chicken Spaghetti
Use Quality Cheese: Freshly shredded cheese melts better than pre-shredded varieties, which contain anti-caking agents. The combination of Monterey Jack and sharp cheddar creates the perfect creamy, tangy balance.
Don’t Overcook Pasta: Cook pasta al dente since it will continue cooking in the oven. This prevents mushy spaghetti in your final dish.
Customize Your Vegetables: Feel free to add mushrooms, spinach, or broccoli for extra nutrition and flavor. If you love creamy pasta dishes, you might also enjoy our Creamy Garlic Parmesan Chicken Pasta for another quick dinner option.
Make Ahead Friendly: Assemble the casserole up to a day in advance, cover, and refrigerate. Add 10-15 minutes to baking time when cooking from cold.
Freezing Instructions: This dish freezes beautifully. Cool completely, wrap tightly, and freeze for up to 3 months. Thaw in refrigerator overnight before baking.
