Ingredient Notes
Here’s what you’ll need to make this creamy Monterey Chicken Spaghetti:
-
Spaghetti (12 oz) – Traditional spaghetti works best, but you can swap with linguine, penne, or even gluten-free pasta.
-
Cooked chicken (3 cups, shredded) – Rotisserie chicken is a time-saver, but you can poach or bake chicken breasts if you prefer.
-
Monterey Jack cheese (2 cups, shredded) – Melts beautifully for a creamy texture. Substitute with Pepper Jack for a little heat.
-
Cream of chicken soup (1 can, 10.5 oz) – Adds creaminess and depth of flavor. Can substitute with cream of mushroom.
-
Sour cream (1 cup) – Balances the richness and adds tanginess. Greek yogurt works as a lighter alternative.
-
Cooked bacon (6 slices, crumbled) – Optional but highly recommended for a smoky twist.
-
Bell peppers (1 cup, diced) – Adds sweetness and color; use any color you like.
-
Mushrooms (1 cup, sliced) – Optional but adds an earthy layer to the dish.
-
Seasonings – Garlic powder, paprika, salt, and black pepper to taste.
-
Fresh parsley (2 tbsp, chopped) – For garnish and freshness.
How To Make Monterey Chicken Spaghetti

Step 1: Cook the Spaghetti
Bring a large pot of salted water to a boil. Cook spaghetti until al dente (about 8-9 minutes). Drain and set aside.
Step 2: Make the Creamy Sauce
In a large bowl, combine cream of chicken soup, sour cream, shredded Monterey Jack cheese, garlic powder, paprika, salt, and pepper. Stir until smooth and creamy.
Step 3: Combine Chicken and Veggies
Add shredded chicken, diced bell peppers, mushrooms, and half the crumbled bacon to the sauce mixture. Stir until everything is evenly coated.
Step 4: Assemble the Casserole
Preheat oven to 350°F (175°C). In a greased 9×13-inch baking dish, layer the cooked spaghetti, pour the creamy chicken mixture over it, and gently toss to combine.
Step 5: Top and Bake
Sprinkle the remaining Monterey Jack cheese and bacon on top. Bake uncovered for 25-30 minutes or until the cheese is bubbly and golden.
Step 6: Garnish and Serve
Remove from the oven and let it rest for 5 minutes before serving. Garnish with fresh parsley and serve warm.
