How to Make French Onion Chicken Noodle Casserole Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350 degrees Fahrenheit and greasing a 9×13-inch baking dish. This ensures the casserole won’t stick and will cook evenly to a bubbly perfection.
Step 2: Cook the Noodles
Boil the egg noodles according to the package directions until they’re perfectly al dente. Drain them well, then spread the noodles evenly in the prepared baking dish — this creates the sturdy, comforting base of your casserole.
Step 3: Mix the Creamy Filling
In a large bowl, combine the chopped cooked chicken, cream of chicken soup, French onion dip, cheddar cheese, and mozzarella cheese. Give everything a good stir so those flavors marry beautifully. Once mixed, pour this creamy concoction over the noodles in your pan, gently stirring to distribute evenly.
Step 4: Add the Crunchy Topping
Sprinkle the French fried onions liberally over the top. These crispy onions are the highlight, adding a satisfying texture and a burst of onion flavor with every bite.
Step 5: Bake to Perfection
Bake the casserole in your preheated oven for 30 minutes or until it’s heated through and the topping is golden brown. The cheese will be melted and oozing, while the onions on top provide that inviting crispness.
Step 6: Garnish and Serve
Once out of the oven, sprinkle some fresh parsley over the casserole. It adds a lovely pop of color and a touch of freshness to balance all the creamy richness.

Garnishes
Fresh parsley is a classic choice, but you can also try chopped chives or a light dusting of paprika to add a bit of flair and brighten the dish. The garnishes not only enhance presentation but also add subtle layers of flavor that lift the casserole.
Side Dishes
This casserole pairs wonderfully with simple sides like a crisp green salad with a zingy vinaigrette, steamed green beans, or even roasted Brussels sprouts. These sides add freshness, crunch, and color, perfectly complementing the creamy richness of the casserole.
Creative Ways to Present
For a fun twist, serve individual portions in mini ramekins for a cozy, personalized touch. You can also try layering with a sprinkle of sautéed mushrooms or caramelized onions for extra depth if you’re feeling adventurous.
Make Ahead and Storage
Storing Leftovers
Let the casserole cool completely before transferring leftovers to an airtight container. Stored in the refrigerator, it will stay delicious for up to 3-4 days, making for easy next-day meals or lunch options.
Freezing
This French Onion Chicken Noodle Casserole Recipe freezes beautifully. Wrap tightly or place in a freezer-safe container and freeze for up to 2 months. When ready, thaw overnight in the fridge for best results before reheating.
Reheating
Reheat individual portions in the microwave or the entire casserole in the oven at 350 degrees until warmed through. Cover with foil to avoid drying out, removing it towards the end for a crispier top if desired.
