French Onion Beef Casserole is a savory and hearty dish that combines the rich flavors of French onion soup with ground beef and egg noodles, all made in one large skillet. Then, for added crunch and onion flavor, crispy fried onions top the casserole. If you are looking for a comforting dish that will be enjoyed by everyone, this is it! I also have the best homemade French Onion Soup you will love!
Ingredients & Substitutions
Onion: I used a yellow onion in this recipe. They have a balanced flavor and sweetness. When cooked low and slow, the natural sugars in the onion caramelize, resulting in a rich, sweet, and savory flavor. They add depth to French onion dishes like this one! Make sure you cook the onions as suggested in this recipe and give yourself a few extra minutes just to make sure they are a soft, almost sticky consistency.
Meat: I prefer ground beef in this casserole. However, you could also use ground pork, ground turkey, or ground chicken.
Onion Soup Mix: For a fresh alternative to store-bought onion soup mix, make your own! If using homemade, you will need about 3 tablespoons of the mix to match the amount in one envelope of store-bought.
French Onion Soup: You will need two cans of condensed French onion soup.
Egg Noodles: The egg noodles cook in the liquid, no need to use a separate pot and cook them ahead of time!
Crispy Fried Onions: Before serving, top the casserole with crispy onion rings. They add a nice crunch to each bite with some added onion flavor.
What To Serve With French Onion Beef Casserole
Although this is a hearty and rich dish, it’s nice to have some side dishes as options. Here are some of my favorites:
- Wedge Salad
- Roasted Vegetables like carrots, asparagus, or green beans
- A basket of bread with slices of a French baguette or ciabatta bread
- Dinner Rolls
- Roasted Potato Wedges
How To Store French Onion Beef Casserole
This recipe does make a large batch, so you may have leftovers. If so, first, let them cool. Then, store the casserole in an airtight container in the refrigerator. I like to store it in portions for easy grab-and-go lunches. It will last up to 3-4 days. Reheat the casserole in the microwave or on the stovetop.
Can I Freeze The Casserole?
Sure! If you are planning to freeze some or all of the casserole, I recommend freezing it without the crispy fried onions. Once the casserole has cooled, store it in a freezer-safe container for up to 2-3 months. When ready to enjoy, let the casserole thaw in the refrigerator overnight before reheating. Top with crispy fried onions.
French Onion Beef Casserole
- In a large skillet (I used a 12-inch) over medium-high heat, melt butter.
- Once melted, add onions and saute for 25-30 minutes. Stir occasionally until the onions are very tender and caramel color.
- Add the ground beef, onion soup mix, salt, and pepper. Stir to break the beef into smaller pieces. Cook until no longer pink, 5-7 minutes. (Remove any excess grease.)
- Add the beef broth and French onion soup.
- Add in the egg noodles, pressing them under the liquid to ensure the noodles are completely submerged. Bring the mixture to a boil.
- Once boiling, cover and reduce the heat to medium-low. Simmer for 10- 12 minutes, or until the noodles are tender.
- Remove the skillet from the heat. Top with crispy fried onions. Serve.

What the Test Kitchen had to say about this recipe:
This recipe is a simple and delicious dish that even the kids will love. Personally, I love that you save on dishes by making everything in one pot.
At first, I wasn't sure this was worthy of a stand-alone recipe (meaning underwhelming for a homemade dish). But, after tasting it again (and again, and again…), I really started to like it and enjoyed the onion flavor with the soft egg noodles and ground beef. It is a flavorful recipe that I would share after giving it another chance.
Simple dish to make and minimal dishes to clean. It tastes like comfort food to me, very much like what my Grandma would put together. The flavors were very delicious, and onions make everything better, especially the fried onions on top!
This is an easy dish with tons of flavor! There's also plenty of texture, but it all works together, nothing overpowers anything else!
I can't get enough of this! It's buttery, fulfilling and beefy. I love how savory and delicious it is while being so easy to make!
Oh man I love this. It's kind of a mashup between beef stroganoff and hamburger helper. It is just such a warm, comforting food and I adore the crispy onions on top!!
