How to Make French Onion Chicken Casserole
This recipe is so simple, and it makes a warm, delicious dish that’s perfect for any time of year. Of course, we especially love our casseroles during those cozy winter months! The first thing you’ll want to do is gather up all your ingredients, just like you’re setting the table for dinner.
Next, get your oven nice and toasty at 350 degrees Fahrenheit. Then, grab your trusty 9×13 casserole dish and give it a quick spritz with nonstick spray so your casserole doesn’t stick. Next, fill a big pot with water and bring it to a rolling boil. Once it’s bubbling away, add those egg noodles and let them cook for about 8 minutes, or until they’re tender but still have a bit of bite to them – we call that ‘al dente’ in fancy cooking terms.
Grab a large skillet and let’s get those chicken pieces sizzling! Sprinkle in the spices and give them a good stir. Keep the heat at a medium level until the chicken starts to turn a lovely golden brown. Then, pour in the wine and add those sliced onions. Turn the heat down to low and let everything simmer together, filling your kitchen with mouthwatering aromas.
Once those egg noodles are cooked to perfection, drain them well and add them to your waiting casserole pan. Now, let’s bring in the stars of the show: that savory chicken and onion mixture, along with a dollop of sour cream, a can of cream of mushroom soup, and a packet of onion soup mix. Give everything a good stir until it’s all blended together like a creamy dream. Spread this mixture evenly in the pan, making sure every noodle gets a taste of the goodness. Now, sprinkle on a generous layer of freshly shredded cheddar cheese – the more, the merrier! Pop the casserole into the oven for 20 minutes, letting the cheese melt into gooey perfection.
After 20 minutes, carefully take the casserole out of the oven and get ready for the grand finale – a generous sprinkling of those crispy, golden French-fried onions. It’s like adding a crown of crunch to your masterpiece! Pop the casserole back into the oven for another 10 minutes, just to let those onions toast up a bit.
Once the oven beeps, your French Onion Chicken Casserole is ready to take center stage. Serve it up piping hot, and watch the smiles light up around the table. Enjoy this comforting, flavor-packed dish that’s sure to become a family favorite!
Recipe Tips for Success
Chicken – I highly recommend using high-quality chicken breast for this recipe. It makes a world of difference in flavor and texture. We love using ButcherBox, as they have the best meats around! You can even get FREE Thanksgiving Turkey (or meat) with your subscription.
Protein Options – For a meatless version, substitute ground beef with meatless crumbles. For a more adventurous twist, try ground venison or bison. Ground beef can also be used as featured in this beef casserole.
French Onion Dip -In a pinch, you can use a 16-ounce container of premade French Onion Dip, either shelf-stable or refrigerated.
Soup Swaps – Not a fan of cream of cream of mushroom soup? Feel free to swap it for cream of celery or cream of chicken soup.
Cheese Choices -While Cheddar cheese is the classic choice for this casserole, swiss cheese works beautifully as well. Shred your own for the freshest flavor.
With these simple substitutions, you can tailor this casserole to your taste buds and dietary needs. Enjoy experimenting and creating your own flavor variations!
Storing this Chicken Casserole
While this casserole is divine when freshly made, you can still savor its goodness for a few days after. Here’s how to keep those flavors intact:
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To revive the crispy onion topping, add a fresh sprinkle before serving.
To reheat, place leftovers in a microwave-safe container and heat until warmed through. If you prefer a more oven-fresh experience, warm the casserole in a preheated 350°F oven for 15 minutes.
Additionally, this meal is perfect for Food Saving and will last up to 3 months in the refrigerator when stored properly.
