🔪How To Make Chicken Spaghetti With Monterey Jack Cheese
Step One: Preheat your oven to 350°F. Cook spaghetti al dente as per package directions. While it cooks, beat the egg in a medium bowl.
Step Two: Add sour cream, cream of chicken soup, Parmesan cheese, Monterey Jack cheese, garlic powder, and onion powder to the bowl with the egg. Stir until well combined.
Step Three: Add cooked chicken, spinach, and half the fried onions to the cheese mixture. Mix everything together thoroughly. Drain the cooked spaghetti and toss it with the chicken mixture.
Step Four: Transfer to a greased 9×13 baking dish and spread evenly.
Step Five: Cover the dish with foil and bake for 30 minutes at 350°F. Remove the foil, and top with remaining cheese and fried onions.
Step Six: Bake uncovered for 5 more minutes until cheese is melted and bubbly. Serve and enjoy!
👩🍳 Expert Tips

- Flavor Boost: Sauté the spinach with garlic in a little butter before adding it to the mixture.
- Perfect Cheese Melt: Grate your own cheese instead of using pre-shredded for better melting and flavor.
- Crispy Topping: Add a sprinkle of breadcrumbs on top with the fried onions for a golden, crispy finish.
