French Onion Soup Beef Sliders Recipe
One of my favorite winter comfort foods is soup. I learned how to make my first french onion soup recipe years ago using a recipe I found from a magazine (which I have since misplaced, so sad!). It took me a few times and putting my memory to the test to recreate it. The soup was so delicious it inspired me to make these beef sliders.
We had a few friends over to watch football and these burgers blew them away. They liked that they were a step up from the traditional “game day” food of buffalo chicken or potato skins. After explaining how easy they were to make it was an even bigger shock!
Do You Actually Make French Onion Soup for These Sliders?
In a nutshell, yes. Your au jus is truly just the base of any good soup, but the onions themselves are caramelized and top the beef rather than remaining in the soup.
What’s the Best Bread to Serve These On?
A classic French onion soup recipe will be served with a crouton on top or at least a slice of crusty bread on the side. For these beef sliders, it was a must to duplicate that texture.
I chose to cute a loaf of French bread into pieces and toast them up nicely before building my sliders. You can easily use any bread you prefer for this including classic slider buns.

Printable Recipe Card Below
Note* I made my own beef stock which is why you see carrots and onions in the liquid. You can skip this step and just use a store bought broth.
- Add broth and seasonings to a sauce pan. Heat to boil, reduce to simmer. Let simmer while preparing burgers and caramelizing onions.
- Slice onions, start slowly cooking them down in a skillet with butter. Stir often. Heat should be on medium low. Onions should be “sweating” (slowly releasing their moisture) not sauteing (sizzling and gaining a quick brown color). Caramelizing occurs when the moisture cooks out and sugars are slowly thickening.
- Combine all burger ingredients in a bowl, mix well. Hand shape patties into a size that best fits your bread.
- Bake or grill burger patties to desired temperature (I usually cook to medium)
- Slice bread, we used a baguette. It holds up the Au Jus dip and has a soft center with crunchy edges!
Assemble your sliders:
- Butter a sheet pan
- Place bottom bread slices on the sheet pan
- Top with provolone cheese, burger patty, caramelized onions and more cheese
- Add the top bread slice and a skewer to hold in place
- Bake until cheese is melted
- Serve with Au Jus on the side
Now dip those sliders in Au Jus and enjoy!
TIP* to turn this into a hearty meal simply simmer the cooked beef patties in the Au Jus with the caramelized onions and serve over creamy mashed potatoes!
