How to Make Monterey Chicken Spaghetti: A Cheesy Delight with a Crunchy Topping Recipe
Step 1: Get Your Oven and Dish Ready
Preheat your oven to 350°F (175°C) so it’s nice and warm by the time you’re ready to bake. Lightly spray a 9×13-inch baking dish with cooking spray. This small step helps ensure your casserole won’t stick and will slide out beautifully when done.
Step 2: Cook the Spaghetti
Bring a large pot of salted water to a boil and add your dried spaghetti. Cook according to the package instructions until the noodles are perfectly al dente. Drain the pasta and set it aside. This al dente texture is key to avoiding mushy spaghetti after baking.
Step 3: Mix the Creamy Chicken Filling
In a large mixing bowl, combine the chopped cooked chicken, cream of chicken soup, sour cream, thawed and drained spinach, one cup of shredded Monterey Jack cheese, the minced garlic, and half of the French fried onions. Stir everything together until well blended. This mixture is the heart of the dish, packing loads of flavor and creamy goodness.
Step 4: Combine Pasta with Filling
Gently fold the cooked spaghetti into the chicken mixture, ensuring every strand is coated and everything is evenly distributed. Pour this hearty mixture into your prepared baking dish, smoothing it out for even cooking.
Step 5: Top with Cheese and Crunch
Sprinkle the remaining one cup of Monterey Jack cheese evenly over the assembled dish. Then, top with the remaining French fried onions. These crispy onions will bake to a golden brown, giving this casserole its signature crunchy topping that perfectly complements the creamy interior.
Step 6: Bake to Perfection
Place your baking dish uncovered in the preheated oven. Bake for 40 to 50 minutes, or until the casserole is bubbling hot and the onions have turned beautifully golden. The smell filling your kitchen at this point will be irresistible!
