👩🍳 How to Make Monterey Chicken Spaghetti
1. Cook the Pasta
Boil spaghetti according to package instructions. Drain and set aside.
2. Sauté the Vegetables
In a large skillet, heat olive oil over medium heat. Add onion, bell pepper, and mushrooms. Cook for 5–7 minutes, until softened and lightly browned.
3. Make the Creamy Sauce
Stir in the cream of chicken soup, sour cream, garlic powder, onion powder, and milk. Cook for 2–3 minutes, stirring until smooth and warmed through.
4. Add Chicken and Cheese
Mix in the cooked chicken and ½ cup of Monterey Jack cheese. Cook for another 2–3 minutes until the cheese melts and the chicken is heated.
5. Combine with Pasta
Add the cooked spaghetti to the skillet and toss until fully coated in the creamy sauce.
6. Optional Baking Step (for a golden, cheesy finish)
Preheat your oven to 350°F (175°C).
Transfer the mixture to a greased 9×13-inch baking dish and top with the remaining Monterey Jack and cheddar cheese.
Bake for 20–25 minutes, or until the top is melted and bubbly.
