Let’s Get Started

Let’s walk through how to bring this Monterey Chicken Spaghetti to life step-by-step:

Step 1: Cook the Pasta

Boil a large pot of salted water and cook the spaghetti according to package instructions until al dente. Drain and set aside.

Step 2: Sauté the Vegetables

In a large skillet, heat the olive oil over medium heat. Add the chopped onion, bell pepper, and mushrooms. Cook for 4–5 minutes, or until softened and fragrant. Season with a pinch of salt and pepper.

Step 3: Make the Sauce

Lower the heat and add the cream of chicken soup, sour cream, milk (or chicken broth), garlic powder, and onion powder to the skillet. Stir until everything is well combined and the sauce is smooth and creamy.

Step 4: Add the Chicken and Cheese

Add the shredded chicken to the sauce and stir to combine. Mix in ½ cup of Monterey Jack and ¼ cup of cheddar cheese, saving the remaining cheese for topping.

Step 5: Combine Pasta and Sauce

Add the cooked spaghetti to the skillet or a large mixing bowl. Toss everything together until the pasta is evenly coated with the sauce mixture.

Step 6: Bake

Preheat your oven to 350°F (175°C). Transfer the spaghetti mixture into a greased 9×13-inch baking dish. Top with the remaining Monterey Jack and cheddar cheese.

Bake uncovered for 20–25 minutes, or until bubbly and lightly golden on top.

Step 7: Garnish and Serve

Remove from the oven and let rest for a few minutes. Garnish with fresh chopped parsley if desired. Serve hot and enjoy that creamy, cheesy goodness!

Servings and Pairing

This recipe yields about 6 servings, making it perfect for a family dinner or small gathering.

Serving Suggestions:

Side salad with a zesty vinaigrette to balance the richness
Garlic bread or dinner rolls for dipping in the cheesy sauce
Roasted vegetables like broccoli or Brussels sprouts

If you want to dress it up, top it with crushed tortilla chips or crispy bacon bits just before baking.
