Rich and delicious, this French Onion Braised Beef is great for a Sunday dinner or even a holiday meal to impress your guests!

This is not your ordinary pot roast. Think of this recipe as a delicious hybrid of French Onion Soup and classic braised beef. Made with simple ingredients that make a big impact, it’s a low and slow dish that you’ll want to make on repeat all winter long.
If you’ve ever made French Onion Soup, you know that it can be a lot of work and super time-consuming. I wanted to figure out a way to capture all of those delicious, rich flavors without having to cook the onions for a really, really long time. Growing up, all of the women in my life cooked with packaged soups, so I figured, why not add it to the mix? After sautéing some sliced onions, I added a package of French Onion Soup Mix (along with some mustard, wine, beef broth, and herbs) to build the base for the beef. It adds such delicious flavor, and everyone just loves how it tastes.
To really drive home the French onion homage, I like to serve the beef with homemade Gruyère toasts, which mimic that broiled cheesy topping, for dipping, as well as with some mashed potatoes to help soak in all that yummy broth!
Ingredients:
- Chuck Roast
- Kosher Salt
- Freshly Ground Black Pepper
- Cassava or All-Purpose Flour
- Avocado Oil
- Yellow Onions
- Garlic Cloves
- Packaged French Onion Soup Mix
- Dijon Mustard
- Dry Red Wine
- Beef Broth
- Fresh Thyme
- Bay Leaf
- Baguette
- Extra Virgin Olive Oil
- Gruyère Cheese
- Flaky Salt
step-by-step:
step one: preheat the oven
Preheat the oven to 275°F.
step two: prep the beef
Cut the chuck roast into 3 to 4 large pieces. Pat dry with paper towels, then season generously with 2 teaspoons of kosher salt and 1 teaspoon of freshly ground black pepper. Dredge each piece in flour, shaking off any excess.
step three: sear the beef
Heat the oil in a 3.5-quart braiser or 5-quart Dutch oven set over medium-high heat. When hot, add the beef and sear until deeply golden brown on all sides, 4 to 6 minutes per side, working in batches if necessary. Transfer to a plate and set aside.

step four: sauté the onions
Reduce the heat to medium. Add the onions, garlic, remaining 1 teaspoon salt, and 1 teaspoon pepper. Cook, stirring occasionally, until the onions are very soft and lightly caramelized, about 8 minutes.
step five: add the remaining ingredients
Stir in the French onion soup mix and Dijon mustard. Slowly pour in the red wine, scraping up the browned bits from the bottom of the pot. Stir in the beef broth, thyme bundle, and bay leaf. Bring to a gentle simmer, 3 to 4 minutes.

step six: nestle the beef in the base
Nestle the seared beef and any juices back into the pot. Cover and transfer to the oven. Braise for 3 hours until the meat is fork-tender. Then, uncover the pot and increase the heat to 300°F. Continue to cook, uncovered, for 30 more minutes. The meat should be fall-apart tender and have a golden-brown crust at the top.

step seven: let the meat rest
Remove from the oven and let rest for 10 minutes to allow the sauce to thicken slightly. Using two forks, shred the tender beef into large pieces for serving.
step eight: make the gruyère toasts (optional)
While the beef rests, preheat the broiler. Arrange the baguette slices on a baking sheet and brush lightly with olive oil. Broil until golden, 1 to 2 minutes per side.
step nine: top with cheese and herbs
Sprinkle each slice with Gruyère and thyme. Return to the broiler until the cheese is melted and bubbling, 1 to 2 minutes. Finish with a pinch of flaky salt.

step ten: serve!
Serve the braised beef over mashed potatoes in shallow bowls with plenty of French onion broth all around, accompanied by Gruyère toasts for dipping. Garnish with more thyme, serve, and enjoy!

recipe faqs:
Yes! You can just use more beef broth in place of the red wine.
Yes! You could cook the roast, then reheat it all in the same pot you cooked it in over medium-low heat on the stovetop for about 15 minutes or until it’s warmed all the way through.
The only thing I’d recommend making fresh are the gruyère toasts, so they don’t get stale.
Any sort of hard, alpine cheese like Swiss, comté, or even cheddar would work well. I just like something sharp and nutty for these toasts!
This recipe is best when braised in the oven, where the sauce reduces beautifully and the beef develops a rich, caramelized crust on top. That said, it can be adapted for the slow cooker if needed. Expect a slightly looser, more brothy consistency, though the flavor will still be delicious. For best results, brown the beef first, then sauté the onions and prepare the sauce on the stovetop. Transfer the browned beef to the slow cooker, pour the sauce over the top, cover, and cook on low for 8 hours, until the meat is tender and easily shredded.

This was so delicious. Made it for a large family dinner last night and it was such a hit. Directions were easy to follow (though I did caramelize my onions for a lot longer than called for, but that’s a personal preference), and the end results were perfect. Instead of making toast with the gruyere, I made gruyere mashed potatoes and it was the perfect combination.
Yum! So glad you liked it!
My family was over the moon when I served this to them last night. My son said it was the dish of the year ( he is a teen)! Every time I make a DD recipe my family loves it.
So happy to hear this!
This was a super easy and delicious meal. Roasted carrots paired well, too!
Do yourself a favor and make this! The flavors are rich and amazing and everything you they hope they will be. It will be a hot minute in the kitchen from start to finish, but there is a lot of downtime in the middle if you stage it. Prep everything, do the range top part, get it in the oven, and then go straight to pureeing some potatoes that you can put in a slow cooker to hold. That will give you a good block of free time to tidy up, listen to music, have wine, and enjoy the wonderful smell of your kitchen before you pull it all together in the last 15 minutes. Again, just do this one! As a bonus, the leftovers make for a crazy good pizza with a mustard horseradish sauce base, provolone/mozzarella topping, and a sprinkling of the sauce. Just sayin’.
Thank you so much!!
This dish is unbelievably outstanding! I cannot describe how delicious it is, made exactly as written! Thank for the fantastic recipe
Wow, this is a hit!! It’s a pretty easy prep then the oven does most of the work. Definitely will put this on repeat!
How would I make this in the crock pot?
Just added this to the FAQ section right above the recipe!
Can you make this in the slow cooker?
You *can*. I will say, it really reduces to perfection by braising in the oven and the beef has a nice crust that forms on the top. If you do it in the crockpot it might feel a little more runny/wet. It will still taste great though! Brown it before, saute the onions/make the sauce then poor it over the browned beef. Cover and cook on low for 8 hours.
Comforting and delicious. I have also sautéed fresh button mushrooms until they are slightly browned and added them for the last 30 minutes.
Is it worth making if you omit the cheese for dairy free?
I made garlic bread with it instead and my family enjoyed it. I will definitely be making it again.
