Egg noodles
Cooked chicken (shredded or diced)
French onion soup mix or canned French onion soup
Cream of chicken soup
Sour cream
Shredded cheese (Swiss, mozzarella, or cheddar all work)
Crispy fried onions (for topping)
Butter
Salt and pepper

directions

I cook the egg noodles according to the package directions, making sure to leave them slightly undercooked since they will continue baking.
In a large bowl, I mix the cream of chicken soup, French onion soup, sour cream, and seasonings until smooth.
I stir in the shredded chicken and noodles, coating everything evenly in the creamy mixture.
I transfer the mixture into a greased casserole dish and sprinkle shredded cheese on top.
I bake uncovered until the casserole is bubbly and golden.
Just before serving, I add crispy fried onions on top for that irresistible crunch.

Servings and timing

This French Onion Chicken Noodle Casserole serves 6 people generously. It usually takes me about 15 minutes to prepare and 30–35 minutes to bake, making it ready in under an hour.

Variations

I like switching up the flavors by using different cheeses—Swiss for a more authentic French onion taste, cheddar for sharpness, or mozzarella for gooey meltiness. Sometimes I add sautéed mushrooms for an earthy flavor or stir in spinach for a veggie boost. For a lighter version, I swap sour cream with Greek yogurt.

storage/reheating

When I have leftovers, I store them in an airtight container in the refrigerator for up to 3 days. To reheat, I usually cover the casserole with foil and warm it in the oven at 350°F until heated through. It also reheats nicely in the microwave, though the crispy onion topping is best added fresh.

FAQs

Can I make this casserole ahead of time?

Yes, I often assemble the casserole up to a day ahead, cover it tightly, and refrigerate. When I’m ready, I bake it, adding a few extra minutes to the cooking time.

Can I freeze French Onion Chicken Noodle Casserole?

I can freeze it before baking by wrapping it well in foil and plastic wrap. It will keep for up to 2 months. I thaw it overnight in the fridge and bake as directed.

What type of chicken works best?

I like using leftover rotisserie chicken because it’s quick and flavorful, but any cooked shredded or diced chicken works perfectly.

Can I use homemade French onion soup?

Absolutely. I’ve used homemade caramelized onion soup before, and it makes the casserole even richer in flavor.

How do I keep the noodles from getting mushy?

I undercook the noodles slightly before mixing them into the casserole, so they don’t over-soften during baking.

Conclusion

French Onion Chicken Noodle Casserole is a hearty, comforting meal that combines all the best flavors of creamy casseroles and savory French onion soup.
