Ingredients
- 12 oz spaghetti noodles
- 2 cups cooked chicken, shredded or diced
- 2 cups Monterey Jack cheese, shredded
- 1 cup sharp cheddar cheese, shredded
- 1/2 cup cream cheese, softened
- 1 cup milk
- 1/2 cup chicken broth
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 red bell pepper, diced
- 1 tsp Italian seasoning
- 1/2 tsp paprika
- Salt and black pepper to taste
- 2 tbsp olive oil
- Fresh parsley for garnish
Step-by-Step Instructions
Step 1: Preheat your oven to 375°F (190°C). Bring a large pot of salted water to boil and cook spaghetti according to package directions until al dente. Drain and set aside.
Step 2: In a large skillet, heat olive oil over medium heat. Add diced onion and cook until translucent, about 3-4 minutes. Add garlic and cook for another minute until fragrant.
Step 3: Add diced bell pepper and cook for 2-3 minutes until slightly softened. Stir in the cooked chicken and season with Italian seasoning, paprika, salt, and pepper.
Step 4: Reduce heat to low and add cream cheese, stirring until melted and combined with the chicken mixture. Gradually pour in milk and chicken broth, stirring continuously until you have a smooth sauce.
Step 5: Combine the cooked spaghetti with the chicken sauce mixture, tossing until all noodles are evenly coated. Stir in 1 cup of Monterey Jack cheese and 1/2 cup of cheddar cheese.
Step 6: Transfer the mixture to a greased 9×13 inch baking dish. Top with remaining cheeses, spreading evenly across the surface.
Step 7: Bake for 20-25 minutes until the cheese is melted and bubbly, and the edges are golden brown. For extra browning, you can broil for the last 2-3 minutes.
Step 8: Remove from oven and let rest for 5 minutes before serving. Garnish with fresh parsley and serve warm.
Expert Tips
For the best results, use freshly shredded cheese instead of pre-shredded, as it melts more smoothly and creates a creamier sauce. If you’re short on time, rotisserie chicken works perfectly in this recipe. You can also prepare this dish ahead of time and refrigerate it before baking – just add an extra 5-10 minutes to the baking time.
This Monterey chicken spaghetti pairs wonderfully with a fresh side salad or roasted vegetables. For a complete meal experience, consider serving it with our Healthy Broccoli Salad with Greek Yogurt Dressing for a balanced dinner.

Frequently Asked Questions
Can I freeze Monterey chicken spaghetti?
Yes, this dish freezes well. Prepare through step 6, then cover tightly and freeze before baking. When ready to eat, thaw in refrigerator overnight and bake as directed, adding extra time if needed.
What can I substitute for Monterey Jack cheese?
If you don’t have Monterey Jack, you can use mozzarella, provolone, or a Mexican blend cheese. The key is to use a good melting cheese that complements the creamy sauce.
How can I make this dish spicier?
Add diced jalapeños, a pinch of cayenne pepper, or use pepper Jack cheese instead of regular Monterey Jack for a spicy kick.
