How to Make Monterey Chicken Spaghetti Recipe
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil and cook the spaghetti according to the package instructions until it’s al dente. Once cooked, drain it well and set aside to prepare the rich sauce and chicken mixture.
Step 2: Sauté the Vegetables
In a large skillet, heat the olive oil over medium heat until shimmering. Add the chopped onion, bell pepper, and sliced mushrooms. Sauté them for about 5 to 7 minutes, stirring occasionally, until the vegetables are tender and just starting to brown. This step builds the savory foundation of the dish.
Step 3: Make the Creamy Sauce
Stir in the can of cream of chicken soup along with the sour cream, garlic powder, onion powder, and milk. Mix everything together well and allow it to cook for 2 to 3 minutes, stirring constantly, until the sauce is smooth, creamy, and heated through. This luscious sauce will coat every bite perfectly.
Step 4: Add Chicken and Cheese
Next, fold in the shredded cooked chicken and 1/2 cup of the shredded Monterey Jack cheese. Let it cook for another 2 to 3 minutes so the cheese melts beautifully and the chicken warms up, marrying all the flavors together in the skillet.
Step 5: Combine with Pasta
Add the cooked spaghetti right into the skillet with the creamy chicken sauce. Toss everything gently but thoroughly to ensure each strand of pasta is generously coated in that irresistible cheesy sauce.
Step 6: (Optional) Bake to Perfection
If you want an extra golden, bubbly finish, preheat your oven to 350°F (175°C). Transfer the entire pasta mixture into a greased 9 by 13-inch baking dish. Sprinkle the remaining Monterey Jack cheese and the shredded cheddar evenly on top. Bake it for 20 to 25 minutes until the cheese on top melts into a bubbly, slightly browned crust. This step makes the dish feel extra special and perfect for dinner parties or family gatherings.
Step 7: Serve
Once baked (or right after combining if you skip baking), sprinkle with fresh chopped parsley if you like, and serve warm so that every cheesy, creamy mouthful is enjoyed at its absolute best.

Garnishes
Adding fresh parsley on top offers a lovely burst of color and fresh aroma that balances the richness of the cheese and cream. You can also experiment with a pinch of smoked paprika or additional shredded cheese for a personalized touch.
Side Dishes
Monterey Chicken Spaghetti pairs wonderfully with simple sides like a crisp green salad, garlic bread, or steamed vegetables. The lightness of these sides contrasts beautifully with the rich pasta, rounding out the meal perfectly.
Creative Ways to Present
Want to impress your guests? Serve the Monterey Chicken Spaghetti in individual ramekins or bake it in small cast-iron skillets for personal portions. Alternatively, layering it with spinach or sun-dried tomatoes before baking adds extra layers of flavor and color that look stunning on the table.
Make Ahead and Storage
Storing Leftovers
Leftover Monterey Chicken Spaghetti can be stored in an airtight container in the refrigerator for up to 3 days. It retains its creamy texture and flavor wonderfully, making it a perfect quick meal for the next day.
Freezing
This dish freezes well if you want to prepare it ahead of time. After fully cooking and cooling, transfer to a freezer-safe container, and it will keep for up to 2 months. Thaw overnight in the refrigerator before reheating for the best results.
Reheating
To reheat, warm the leftovers gently in a microwave or on the stovetop with a splash of milk to loosen the sauce, stirring occasionally until heated through. If reheating from frozen, oven baking covered with foil helps keep the pasta moist and creamy.
FAQs
Can I use another type of cheese instead of Monterey Jack?
Absolutely! While Monterey Jack gives a mild, creamy melt, cheddar, mozzarella, or even pepper jack can be excellent alternatives depending on your flavor preferences and desired spice level.
Is it necessary to bake the dish?
Baking is optional. It adds a delightful bubbly, browned cheese topping, but the dish can be enjoyed just as deliciously right from the skillet.
Can I make this recipe vegetarian?
You can swap the chicken for hearty vegetables like zucchini or use a meat substitute, and make sure to use vegetable broth instead of chicken broth for a vegetarian version.
What pasta works best for this recipe?
Spaghetti is classic, but feel free to use fettuccine, penne, or any pasta you love. Just make sure to cook it al dente so it holds up well in the creamy sauce.
How spicy is the Monterey Chicken Spaghetti Recipe?
This recipe is mild, focusing on cheesy, creamy comfort. You can easily add crushed red pepper flakes or diced jalapeños during the sautéing step to bring in some heat if you like.

This Monterey Chicken Spaghetti Recipe truly embodies cozy comfort food with a touch of cheesy indulgence that feels like a warm welcome after a long day.
