Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Spaghetti
Spaghetti forms the hearty base of the dish, holding the creamy sauce and shredded chicken evenly throughout each serving.

Cooked shredded chicken
Tender chicken provides lean protein and absorbs the flavors of the sauce beautifully. Rotisserie chicken works especially well for convenience.

Monterey Jack cheese
This cheese melts smoothly and delivers a mild, buttery flavor that defines the dish.

Cream of chicken soup
Cream of chicken soup creates a rich and creamy base, helping bind the ingredients together.

Sour cream
Sour cream adds tanginess and smooth texture, balancing the richness of the cheese and soup.

Diced green chilies
Green chilies provide subtle heat and a mild Southwestern flavor without overpowering the dish.

Chicken broth
Broth loosens the sauce slightly and enhances the savory depth.

Garlic powder
Garlic powder contributes warm, aromatic flavor throughout the casserole.

Onion powder
Onion powder adds gentle sweetness and depth to the creamy sauce.

Salt and black pepper
These basic seasonings enhance and balance all the flavors in the dish.

Directions

Preheat your oven to 350°F (175°C) and lightly grease a large baking dish. Cook the spaghetti in salted boiling water according to package instructions until al dente. Drain and set aside.

In a large mixing bowl, combine the cream of chicken soup, sour cream, chicken broth, garlic powder, onion powder, salt, and black pepper. Stir until smooth and well blended. Fold in the shredded chicken and diced green chilies, ensuring everything is evenly coated in the creamy mixture.

Add the cooked spaghetti to the bowl and gently toss until the pasta is fully incorporated with the sauce. Transfer the mixture into the prepared baking dish and spread it evenly.

Sprinkle the shredded Monterey Jack cheese generously over the top. Bake uncovered for 25 to 30 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges. Allow the dish to rest for about 5 to 10 minutes before serving so the sauce can settle and thicken slightly.

Storage/reheating

Store leftovers in an airtight container in the refrigerator for up to four days. Reheat individual portions in the microwave until warmed through, adding a small splash of chicken broth if the pasta seems dry.

Variations and Customizations

Monterey Chicken Spaghetti is highly adaptable, allowing you to tailor it to your taste preferences. For a slightly spicier version, add diced jalapeños or a pinch of cayenne pepper to the sauce. I once added a small amount of smoked paprika, which gave the dish a subtle smoky depth that complemented the cheese beautifully.

If you prefer a lighter option, substitute Greek yogurt for sour cream and use reduced-fat cheese. You can also replace part of the cream of chicken soup with a homemade white sauce if you want more control over ingredients.

Vegetable additions work wonderfully in this recipe. Sautéed bell peppers, mushrooms, or spinach can be folded into the mixture before baking for added texture and nutrition. For extra crunch, sprinkle buttered breadcrumbs or crushed tortilla chips on top before baking.

To change the protein, turkey or even cooked shrimp can be substituted for chicken. You can also experiment with a blend of cheeses such as cheddar and Monterey Jack for a sharper flavor profile.
