Ingredient notes and easy substitutions

• Egg noodles form the base of the French onion soup noodle casserole. I recommend sticking with egg noodles, but you can substitute another sturdy pasta in a pinch.
• Chicken – a rotisserie chicken will be your best friend here. True convenience. No muss, no fuss!
• Canned French onion soup and cream of chicken soup – are old standbys and pantry staples that provide flavor and convenience.
• Cheddar Cheese – I think there is a law that requires cheese in casseroles, and who am I to argue with that?
• French fried onions – add crunchy bits of deliciousness. They are another pantry staple and a flavorful and easy-peasy topping.
• Parsley – an optional garnish adds a pop of color and freshness.

Easy variations to try

• Before baking, you can add a cup or so of green beans, asparagus, english peas, mushrooms, or broccoli to the casserole.
• You could also substitute homemade fried onion rings for canned ones.

Serving suggestions:

I like to serve this creamy French onion chicken and noodles with a light side dish such as my classic house salad, cucumber and tomato salad, or broccoli salad. A slice of Texas toast garlic bread rounds out the meal nicely.

Why egg noodles work so well in this casserole

Most French onion chicken casseroles use rice, but I actually prefer egg noodles here because they soak up the creamy French onion sauce beautifully without becoming heavy or mushy.

The noodles also make this casserole feel more like an old-fashioned chicken noodle bake, the kind of cozy comfort food recipe everybody goes back for seconds of.

Make-ahead, freezer, and storage tips

This chicken casserole with French onion soup is best eaten the day it is made. However, if you have leftovers, they can be stored in an airtight container in the fridge for up to four days.

To reheat leftovers, add a teaspoon or so of water or chicken broth, cover with foil, and warm in a 350°F oven for about 15 minutes. I also like adding a handful of fresh fried onions to the top.

Tips to ensure this recipe turns out perfectly

Because it’s just my husband and me when I make chicken and French onion soup casserole, I usually divide the chicken and noodle mixture in half or thirds, bake one, and then freeze the rest to serve another time.

Be sure to wait to add your French fried onion topping until you are ready to bake the casserole.
