Ingredients

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

Optional substitutions

• Use gluten-free spaghetti for those avoiding gluten.
• Swap cream of chicken soup for a dairy-free alternative if required.
• For a vegan version, substitute vegan cheese and plant-based chicken and use dairy-free sour cream and soup alternatives.

Instructions

Step 1: Preheat the oven

Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with cooking spray or grease with butter or oil.

Step 2: Cook the pasta

Cook the spaghetti according to package directions until al dente. Drain well and set aside.

Step 3: Mix the filling

In a large bowl, combine the chopped cooked chicken, both cans of cream of chicken soup, sour cream, thawed and well-drained spinach, 1 cup of shredded Monterey Jack cheese, minced garlic, and half the can of French fried onions. Stir until evenly mixed.

Step 4: Combine pasta and filling

Add the cooked spaghetti to the chicken mixture and toss gently until the pasta is fully coated and ingredients are evenly distributed.

Step 5: Transfer and top

Pour the mixture into the prepared baking dish and smooth the surface. Sprinkle the remaining 1 cup of Monterey Jack cheese evenly over the top, then finish with the remaining French fried onions for a crunchy topping.

Step 6: Bake

Bake uncovered for 40–50 minutes, or until the casserole is hot and bubbly, the cheese has fully melted, and the onion topping is golden and crisp. If you prefer an extra-crispy top, broil for 2–3 minutes at the end, watching closely to avoid burning.

Notes & Tips

• Drain spinach thoroughly before adding it to the mixture to prevent a watery casserole.
• For quicker prep, use rotisserie or leftover cooked chicken.
• Add a pinch of red pepper flakes or a small amount of diced green chiles for a mild spicy note.
• Mix in cooked bacon or sautéed mushrooms for extra savory depth.
• Use freshly grated Monterey Jack for best melt and flavor.

Serving Suggestions

This Monterey Chicken Spaghetti pairs well with a crisp green salad, steamed or roasted vegetables, and garlic bread. For drinks, a light white wine such as Chardonnay or a refreshing lemonade complements the creamy, cheesy flavors. Serve hot and offer extra fried onions or chopped fresh herbs like parsley for garnish.
