What Is Monterey Chicken Spaghetti?
Monterey Chicken Spaghetti is a rich and creamy pasta dish featuring cooked spaghetti noodles, tender pieces of chicken (often shredded or cubed), and a flavorful sauce made with cream of chicken soup, Rotel (diced tomatoes with green chilies), sour cream, and plenty of melted Monterey Jack cheese. It’s baked until bubbly, golden, and irresistibly cheesy.
This dish has its roots in the tradition of creamy baked casseroles, which became popular because they combine simplicity with comfort. The Monterey Jack cheese — known for its mild, buttery flavor and excellent melting properties — gives this recipe its signature creamy texture and satisfying cheesiness.

Step-by-Step Cooking Instructions
Making Monterey Chicken Spaghetti is easy, even for beginners. Follow these steps for the best results.
Step 1: Cook the Spaghetti
Boil spaghetti according to the package directions until al dente. Drain and set aside.
Step 2: Sauté the Aromatics
In a large skillet, heat olive oil or butter over medium heat. Add onions and cook until soft and translucent, about 3–4 minutes. Stir in garlic and cook for another 30 seconds until fragrant.
Step 3: Make the Creamy Sauce
Add cream of chicken soup, drained diced tomatoes with chilies, sour cream, smoked paprika, salt, black pepper, and chili powder (if using). Stir until smooth and heated through.
Step 4: Add Chicken and Cheese
Fold in the cooked chicken and 1 ½ cups of shredded Monterey Jack cheese. Stir until the cheese melts and the sauce is creamy.
Step 5: Combine with Spaghetti
Toss the cooked spaghetti into the sauce until all noodles are evenly coated.
Step 6: Bake
Preheat oven to 375°F (190°C). Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle the remaining cheese on top. Bake uncovered for 15–20 minutes or until bubbly and lightly golden.
Step 7: Garnish and Serve
Sprinkle with fresh parsley or chives before serving.
Pro Tips for the Perfect Monterey Chicken Spaghetti
- Don’t overcook the pasta: Slightly undercook it before baking to avoid mushy noodles.
- Use freshly shredded cheese: Pre-shredded cheese contains anti-caking agents that affect melting.
- Let it rest for 5 minutes after baking: This helps the sauce set for cleaner slices.
- Poach chicken gently: If cooking fresh, simmer it in broth for more flavor and juiciness.
Common Mistakes to Avoid
- Adding too much liquid – Undrained tomatoes or excess broth can make the dish watery.
- Over-salting – Cream soups and cheese already have salt; taste before adding more.
- Skipping the bake step – Baking melds the flavors and creates a perfect cheesy crust.
- Forgetting to preheat the oven – Cold starts affect texture and melting.
Delicious Variations to Try
- Tex-Mex Style: Add black beans, corn, and top with crushed tortilla chips.
- Extra Creamy Version: Stir in a little cream cheese or heavy cream.
- Vegetable Loaded: Add sautéed spinach, bell peppers, or peas.
- Spicy Lovers: Swap Monterey Jack for pepper jack cheese and add jalapeños.
- Low-Carb Option: Use zucchini noodles or spaghetti squash instead of pasta.
What to Serve with Monterey Chicken Spaghetti
While this is a full meal on its own, here are some great pairings:
- Garlic Bread or Cheesy Breadsticks

- Steamed or Roasted Vegetables (broccoli, asparagus, or green beans)
- Fruit Salad or Light Dessert to balance the richness
Make-Ahead, Storage, and Freezing
- Refrigeration: Store leftovers in an airtight container for up to 4 days.
- Freezing: Freeze in a sealed container for up to 2 months. Thaw overnight before baking.
- Reheating: Microwave individual portions or warm in a 350°F oven until heated through.
