The Key Ingredients You’ll Need

To create this cheesy and delicious casserole, you won’t need any fancy ingredients. In fact, many of the components are pantry staples that you might already have on hand. Here’s what you’ll need:

1. Spaghetti

A classic pasta base for this casserole. Spaghetti is the perfect choice for holding all the cheesy goodness and creamy sauce together. You can also substitute with another pasta of your choice, but spaghetti works wonderfully here.

2. Chicken

This recipe calls for 4 cups of cooked chicken, which can be either rotisserie chicken, leftover chicken, or freshly cooked chicken breasts. You can use boneless skinless chicken breasts, thighs, or any cut you prefer. For added convenience, shredded or cubed chicken will work great.

3. Cream of Chicken Soup

The cream of chicken soup serves as the creamy base for this casserole, binding everything together. It adds a comforting, rich flavor that makes this dish truly indulgent. For a lighter version, you can opt for low-fat or reduced-sodium cream of chicken soup.

4. Sour Cream

The sour cream adds a tangy richness that balances the flavors of the cream of chicken soup, adding an extra layer of creaminess that’s hard to resist.

5. Frozen Spinach

Adding frozen spinach not only enhances the nutritional value of this dish but also gives it a lovely pop of green color. Just make sure to thaw and drain the spinach well to avoid excess moisture in the casserole.

6. Monterey Jack Cheese

The Monterey Jack cheese is the star of this dish. It’s mild, creamy, and melts beautifully. You’ll need two cups of shredded cheese, divided between the casserole mixture and the topping.

7. Garlic

A couple of minced garlic cloves will infuse the dish with aromatic flavor, enhancing the overall taste without overpowering the other ingredients.

8. French Fried Onions

The French Fried Onions add that golden, crispy topping that transforms this dish from ordinary to extraordinary. The onions not only give the casserole an irresistible crunch but also add a savory flavor contrast that complements the creamy pasta base.

Now that you know the key ingredients, let’s dive into how to make this delicious Monterey Chicken Spaghetti Casserole.

Step-by-Step Directions to Make Monterey Chicken Spaghetti

1. Preheat the Oven

Begin by preheating your oven to 350°F (175°C). While the oven is heating up, lightly spray a 9×13-inch baking dish with cooking spray. This will help prevent the casserole from sticking to the pan and make for an easier cleanup.

2. Cook the Spaghetti

Cook 12 ounces of dried spaghetti according to the package directions until it’s al dente. Once cooked, drain the pasta and set it aside to cool slightly.

3. Prepare the Casserole Mixture

In a large mixing bowl, combine the following ingredients:

  • 4 cups of chopped cooked chicken (whether shredded, cubed, or from a rotisserie chicken)
  • 1 (16-ounce) container of sour cream
  • 2 (10.5-ounce) cans of unsalted cream of chicken soup
  • 1 (10-ounce) package of frozen spinach, thawed and well-drained
  • 1 cup of shredded Monterey Jack cheese
  • 2 minced garlic cloves
  • ½ can of French Fried Onions

Stir everything together until fully combined. The creamy soup, tangy sour cream, and gooey cheese create a luscious base that coats the chicken and spinach perfectly.

4. Combine Pasta and Mixture

Add the cooked, drained spaghetti into the bowl with the creamy chicken mixture. Stir gently, making sure the pasta is thoroughly coated with the sauce and ingredients.

5. Assemble the Casserole

Transfer the spaghetti and chicken mixture into the prepared baking dish. Use a spatula to spread it out evenly, ensuring that the mixture is well distributed.

6. Add Toppings

Sprinkle the remaining 1 cup of shredded Monterey Jack cheese evenly over the top of the casserole. Then, take the remaining French Fried Onions and scatter them over the cheese. The onions will form a crispy, golden topping as the casserole bakes, adding both flavor and texture.

7. Bake the Casserole

Place the casserole in the preheated oven and bake, uncovered, for 40 to 50 minutes, or until the casserole is hot and bubbly. You’ll know it’s ready when the cheese is melted and golden, and the onions are crispy and brown.

8. Serve and Enjoy

Once your casserole is done baking, let it cool for a few minutes before serving. Slice into hearty portions and enjoy the comforting flavors of this easy-to-make Monterey Chicken Spaghetti casserole. Whether served with a simple salad or some garlic bread, it’s a meal that will leave everyone satisfied.

  • Add Vegetables: Want to sneak in more vegetables? You can add other veggies like mushrooms, bell peppers, or peas to the casserole mix. It’s a great way to boost the nutritional value of the dish.
  • Spicy Kick: If you love a bit of heat, consider adding diced jalapeños or a pinch of red pepper flakes to the mixture for an extra zing.
