Ingredients

12 ounces spaghetti, cooked according to package instructions
4 cups cooked chicken, chopped
1 (16-ounce) container sour cream
2 (10.5-ounce) cans unsalted cream of chicken soup
1 (10-ounce) package frozen spinach, thawed and drained
2 cups shredded Monterey Jack cheese, divided
2 garlic cloves, minced
1 (6-ounce) can French’s French Fried Onions, divided

Instructions

Step 1: Preheat the Oven

Start by preheating your oven to 350°F. Lightly spray a 9×13-inch baking dish with cooking spray to ensure easy serving and cleanup.

Step 2: Prepare the Pasta

Cook the spaghetti according to package instructions until it reaches an al dente texture. Drain the pasta well and set it aside. This step ensures the noodles won’t become mushy during baking.

Step 3: Mix the Ingredients

In a large mixing bowl, combine the cooked chicken, sour cream, cream of chicken soup, thawed spinach, 1 cup of Monterey Jack cheese, minced garlic, and half of the can of French Fried Onions. Stir well until all ingredients are evenly mixed, creating a creamy and flavorful base for the spaghetti.

Step 4: Combine Pasta and Mixture

Add the cooked spaghetti to the chicken mixture, stirring until the noodles are evenly coated with the creamy sauce. Pour the entire mixture into the prepared baking dish, spreading it out for even cooking.

Step 5: Add Toppings

Sprinkle the remaining Monterey Jack cheese evenly over the top of the pasta. Finish by topping with the remaining French Fried Onions. This combination of cheese and crispy onions adds both texture and flavor, making every bite satisfying.

Step 6: Bake

Place the baking dish in the preheated oven and bake uncovered for 40 to 50 minutes. The casserole is ready when it’s hot and bubbly, and the French Fried Onions are golden brown. This baking time allows all the flavors to meld together perfectly while creating a crispy topping.

Notes

Serving Suggestions:
Monterey Chicken Spaghetti is a hearty, all-in-one meal that pairs wonderfully with light sides to balance its rich flavors. Here are a few serving ideas:

Side Salad – A simple green salad with a tangy vinaigrette can add freshness and a hint of acidity that complements the creamy casserole.
Garlic Bread or Dinner Rolls – These are great for soaking up any extra sauce, adding a delicious crunch alongside the tender spaghetti.
Steamed Vegetables – Lightly steamed broccoli, green beans, or asparagus add a pop of color and freshness, making the meal feel complete.

Storage Tips:

Refrigerating Leftovers:

Allow the casserole to cool to room temperature.
Transfer any leftovers into an airtight container, or cover the baking dish tightly with plastic wrap or aluminum foil.
Store in the refrigerator for up to 3-4 days. Reheat individual servings in the microwave or reheat the entire dish in a 350°F oven until warmed through.

Freezing for Later:
Monterey Chicken Spaghetti can be frozen before or after baking:

To Freeze Before Baking: Assemble the casserole as directed, then cover tightly with plastic wrap followed by aluminum foil. Store in the freezer for up to 2-3 months. When ready to bake, thaw in the refrigerator overnight and bake as directed, adding a few extra minutes if needed.
To Freeze After Baking: Let the casserole cool completely, then cover with plastic wrap and foil. Freeze for up to 2 months. To reheat, thaw in the refrigerator overnight and warm in a 350°F oven until hot and bubbly.
