How to Make Monterey Chicken Spaghetti Casserole Recipe
Step 1: Prepping the Pan and Spaghetti
Begin by lightly spraying a 9×13-inch baking pan with cooking spray. This prevents sticking while ensuring easy cleanup later. Cook the spaghetti according to package instructions until al dente, then drain well—making sure it’s not soggy is key for perfectly textured casserole.
Step 2: Mixing the Creamy Base
In a large bowl, combine the sour cream, cream of chicken soup, minced garlic, and thawed, drained spinach. This blend delivers the creamy, savory heart of the casserole and allows every strand of spaghetti to soak it up.
Step 3: Adding Chicken and Cheese
Fold the chopped cooked chicken and 1 cup of shredded Monterey Jack cheese into your creamy mixture. The chicken brings rich, meaty flavor, while the cheese softens into a luscious layer within the casserole.
Step 4: Combining Spaghetti and Sauce
Pour the drained spaghetti into the bowl with your creamy chicken mixture. Gently toss everything together, ensuring the noodles are evenly coated but not broken up.
Step 5: Assembling the Casserole
Transfer the entire mixture into the prepared baking pan. Spread it out evenly. Then sprinkle the remaining 1 cup of shredded Monterey Jack cheese on top, followed by half of the French fried onions. These will give a fantastic flavor and crispness after baking.
Step 6: Baking to Perfection
Bake the casserole at 350°F (175°C) for about 35 minutes or until the cheese is melted, bubbly, and the edges are golden brown. During the last 5 minutes, sprinkle the remaining French fried onions on top to toast to crunchy perfection without burning.
How to Serve Monterey Chicken Spaghetti Casserole Recipe
Garnishes
For an extra pop of freshness and color, sprinkle chopped fresh parsley or chives on top just before serving. A light squeeze of lemon juice can also brighten up the creamy richness wonderfully.
Side Dishes
This casserole is hearty on its own but pairs beautifully with crisp green salads, steamed vegetables, or roasted asparagus. You might also enjoy it alongside warm crusty bread or garlic knots to soak up any extra sauce.
Creative Ways to Present
For a more unique presentation, try layering the casserole in individual ramekins for personal servings. You can also bake it in mini cast iron skillets and serve hot from the oven—charming for dinner parties or family gatherings.
Make Ahead and Storage
Storing Leftovers
Leftover Monterey Chicken Spaghetti Casserole Recipe keeps wonderfully in an airtight container in the refrigerator for up to 4 days. The flavors develop even more, making those next-day meals just as delightful.
Freezing
This casserole freezes well before baking. Assemble it in a freezer-safe dish, tightly cover with foil and plastic wrap, and freeze for up to 3 months. When ready to use, thaw overnight in the fridge before baking as directed.
Reheating
Reheat leftovers covered with foil in a 350°F oven for 20-25 minutes or until warmed through. For quicker reheating, microwave individual portions but keep in mind the baked top won’t stay crisp.
FAQs
Can I use fresh spinach instead of frozen?
Absolutely! Use about 3 cups of fresh spinach, sauté it lightly to remove excess moisture, then drain well before mixing it into the casserole.
Is there a way to make this casserole gluten-free?
Yes, simply swap out regular spaghetti for your favorite gluten-free pasta, and use gluten-free cream of chicken soup if available. The dish remains deliciously comforting.
Can I add other vegetables to this recipe?
Definitely! Consider sneaking in some sautéed mushrooms, diced bell peppers, or even corn to add additional flavor and texture.
What type of chicken works best?
Cooked, shredded rotisserie chicken works beautifully for convenience, but you can also use grilled, baked, or poached chicken breasts, chopped into bite-sized pieces.

This Monterey Chicken Spaghetti Casserole Recipe is mild and creamy, making it perfect for all palates. You can add a pinch of cayenne or chopped jalapeños if you want a kick of heat.
