How to Make Monterey Chicken Spaghetti Casserole Recipe
Step 1: Prepare Your Oven and Pasta
Start by preheating your oven to 350ºF and lightly spray a 9×13-inch baking dish with cooking spray—this makes clean up a breeze and prevents sticking. Next, cook the spaghetti according to package instructions until al dente; this ensures the noodles hold their shape during baking without becoming mushy. Drain the spaghetti well to avoid excess water diluting the flavors in your casserole.
Step 2: Mix Your Creamy Chicken Filling
In a large bowl, stir together the cooked chicken, both cans of cream of chicken soup, sour cream, thawed and drained spinach, one cup of shredded Monterey Jack cheese, minced garlic, and half the can of French’s French Fried Onions. This combination of creamy, cheesy, and savory ingredients is what makes this Monterey Chicken Spaghetti Casserole Recipe truly comforting. Mixing everything together ensures every bite is packed with flavor.
Step 3: Combine Pasta and Filling
Add your drained spaghetti to the mixture, folding gently to coat each strand with the creamy chicken mixture. Be careful not to break the noodles. Once combined, transfer this hearty blend into the prepared baking dish, smoothing the top evenly so it bakes uniformly and looks inviting.
Step 4: Add the Cheesy Crunchy Topping
Sprinkle the remaining shredded Monterey Jack cheese evenly over the casserole, then top it off with the rest of the French fried onions. This topping will bake to a gorgeous golden brown, adding a wonderful crispy texture that contrasts with the creamy pasta beneath. Don’t skip this step—it’s what makes this casserole feel extra special.
Step 5: Bake and Enjoy
Bake the casserole uncovered in the preheated oven for 40 to 50 minutes. You’re looking for a bubbly, golden top and that enticing aroma filling your kitchen. This baking time allows flavors to meld beautifully and the cheese to melt perfectly. Once out of the oven, let it rest a few minutes before serving so it sets up nicely for easy slicing.
How to Serve Monterey Chicken Spaghetti Casserole Recipe
Garnishes
Consider garnishing with a sprinkle of fresh chopped parsley or chives for a pop of green freshness and mild oniony touch. A light dusting of freshly cracked black pepper can enhance the creamy richness as well. These small touches add visual appeal and a little extra flavor lift to your warm casserole.
Side Dishes
This casserole pairs wonderfully with fresh, crisp side salads—think a tangy vinaigrette or a simple garden salad to balance the creaminess. Roasted vegetables like asparagus or broccoli also make for vibrant, nutritious accompaniments, while a slice of crusty garlic bread is perfect if you’re craving something indulgent yet simple.
Creative Ways to Present
For a fun twist, serve individual portions in small ramekins or oven-safe bowls topped with extra fried onions just before broiling to get an ultra-crispy finish. You can also turn this dish into a layered bake by alternating spaghetti mixture and cheese in a deep glass dish, creating a visually dramatic presentation when sliced.
Make Ahead and Storage
Storing Leftovers
Leftovers of this Monterey Chicken Spaghetti Casserole Recipe store beautifully in an airtight container in the refrigerator for up to 3 days. Simply cover tightly, and you’ll be able to enjoy the comforting flavors all over again without any loss of deliciousness.
Freezing
This casserole freezes wonderfully, making it an excellent make-ahead meal. Freeze in a sealed container for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator before reheating. This is perfect for busy weeknights when you want a home-cooked meal with minimal effort.
Reheating
Reheat leftovers covered in the microwave or oven until warmed through. If using the oven, cover with foil and heat at 350ºF for about 20 minutes, then uncover for the last 5 minutes to revive the crispy onion topping. This step helps bring back all the casserole’s charm and texture.
FAQs
Can I use fresh spinach instead of frozen?
Absolutely! Fresh spinach works great when wilted down and drained thoroughly before mixing in. Just sauté it lightly to remove excess moisture so your casserole doesn’t become watery.
Is there a substitute for sour cream?
You can substitute sour cream with Greek yogurt or cream cheese for a similar creamy tang, though this will slightly alter the texture and flavor. Greek yogurt is a lighter option, while cream cheese will add richness.
Can I make this recipe vegetarian?
Yes! Simply replace the chicken with your favorite plant-based protein like seasoned tofu, chickpeas, or a meat substitute. Also, make sure your cream of chicken soup is replaced with a vegetable-based cream soup.
How spicy is this casserole?
This dish is mild and comforting with no spicy heat, which makes it perfect for all ages. If you want to add a bit of a kick, consider a pinch of cayenne or chopped jalapeños mixed in.
Can I prepare this dish in advance and bake later?
Definitely! Assemble the casserole as directed, then cover and refrigerate for up to 24 hours before baking. Just add a few extra minutes to baking time if baking straight from the fridge.
