Step‑by‑Step Instructions for Monterey Chicken Spaghetti
Step 1: Cook the Pasta
Bring a large pot of water to a boil and add a generous pinch of salt. Cook spaghetti according to the package instructions until al dente, usually about 8-10 minutes. Once done, drain the pasta in a colander, shaking off any excess water, and set it aside while you prepare the creamy sauce for your Monterey Chicken Spaghetti.
Step 2: Sauté Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion, bell pepper, and sliced mushrooms. Sauté these vegetables for 5-7 minutes, stirring occasionally, until they are tender and the onions become translucent. This fragrant mixture will form the base for your delicious Monterey Chicken Spaghetti sauce.
Step 3: Make the Sauce
Once your vegetables are soft, incorporate one can of cream of chicken soup and half a cup of sour cream into the skillet. Stir in garlic powder, onion powder, and about a cup of milk, mixing until you achieve a smooth consistency. Continue to cook the sauce for 3-4 minutes, allowing it to heat through, and feel how it thickens, creating a cozy base for your Monterey Chicken Spaghetti.
Step 4: Add Chicken and Cheese
Next, fold in your cooked chicken, breaking it into bite-sized pieces as you go. Sprinkle in half of the shredded Monterey Jack cheese and stir to combine. Continue cooking for an additional 3-5 minutes until the cheese melts beautifully into the sauce, adding a creamy texture that elevates your Monterey Chicken Spaghetti to a comfort food classic.
Step 5: Combine with Pasta
Carefully add the drained spaghetti into the skillet with the sauce, tossing everything together gently until the pasta is well coated. Ensure each strand of spaghetti is enveloped in that luscious creamy sauce, making your Monterey Chicken Spaghetti look absolutely irresistible. Give it a final stir and enjoy the delightful aromas filling your kitchen.
Step 6: Bake (Optional)
For a deliciously baked finish, transfer your creamy Monterey Chicken Spaghetti to a greased baking dish. Sprinkle the remaining Monterey Jack cheese generously on top and pop it in a preheated oven at 350°F (175°C) for 20-25 minutes, or until the cheese is bubbly and slightly golden. This step will add a delightful crispiness that makes every bite extra special.
Step 7: Serve
Remove your Monterey Chicken Spaghetti from the oven and let it sit for a few minutes to cool slightly. Garnish with fresh parsley for a pop of color and added freshness. Serve warm alongside garlic bread and a simple salad, allowing everyone to enjoy a hearty family meal that brings smiles to the table.
