Ingredients You’ll Need
- 2 tablespoons butter: Used for caramelizing onions, this adds richness. You can substitute with vegan butter for a dairy-free option.
- 1 tablespoon olive oil: Helps cook the onions evenly and prevents them from sticking. Avocado oil works well too.
- 3 yellow onions, thinly sliced: The star of the dish, lending a sweet, rich flavor when caramelized. Using a mandolin makes the slicing uniform and easier!
- 1 tablespoon minced fresh thyme leaves: Adds an aromatic herbiness that balances the dish. Dried thyme can be used in a pinch, just reduce the amount.
- 2 teaspoons Dijon mustard: Gives a tangy zest to the beef and complements the sweetness of the onions.
- 1 tablespoon balsamic vinegar: Introduces acidity and depth. Red wine vinegar can be a great substitute.
- 1 ½ lbs grass-fed 85/15 ground beef: The ideal mix for juicy burgers. Feel free to use ground turkey or a plant-based substitute if desired!
- 1 tablespoon Worcestershire sauce: Adds umami and complexity to the beef. A vegan version works too!
- 1 ½ teaspoons garlic powder: Enhances the savoriness of the meat blend. Fresh garlic is wonderful if you prefer it.
- 1 teaspoon kosher salt: Essential for seasoning. Sea salt would be a good alternative.
- ½ teaspoon freshly ground black pepper: Adds a hint of spice; adjust to taste.
- 4 brioche buns, toasted in butter: Soft and slightly sweet, perfect for holding everything together. Any sturdy bun can be a good swap.
- 8 oz double cream brie, cut into slices: Creamy and rich, it elevates your burger to gourmet status. Camembert can be an excellent substitute.
- 2 cups arugula: Adds a fresh, peppery crunch. Spinach can be a suitable alternative.
- ½ cup mayonnaise: Acts as the base for the burger sauce. Vegan mayo is an option if you’re looking for dairy-free.
- 1 teaspoon prepared horseradish: Offers a zesty punch. If unavailable, you can skip it or use a dab of hot sauce instead.
- 1 tablespoon Dijon mustard: This will blend with mayonnaise to create the burger sauce.
- 1 teaspoon honey: Adds a touch of sweetness to balance the flavors. Maple syrup can be used for a vegan version.
How to Make French Onion Burgers
Caramelize the onions: In a large Dutch oven, melt 2 tablespoons of butter with 1 tablespoon of olive oil over medium heat. When hot and foamy, add the sliced onions and toss well to coat. Cover the pot and let the onions cook for 10 minutes until they start to wilt. Once the lid is off, reduce the heat and stir in thyme, salt, and pepper. Cook them for about 30-40 minutes, stirring occasionally until they’re deeply caramelized. Finish by stirring in the Dijon mustard and balsamic vinegar, then set aside.
Mix the burger meat: Transfer half of the cooled caramelized onions to a cutting board and finely chop. Add these chopped onions to a large mixing bowl along with 1 ½ lbs grass-fed ground beef, 1 tablespoon Worcestershire sauce, 1 tablespoon Dijon mustard, 1 tablespoon dehydrated minced onions, 1 ½ teaspoons garlic powder, salt, and pepper. With your hands, gently combine, then divide into 4 equal balls, shaping each into a patty about 1 inch thick and slightly larger than your buns. Make a small indentation in the center of each patty to prevent puffing.
Make the burger sauce: In a small bowl, mix together ½ cup mayonnaise, 1 tablespoon Dijon mustard, 1 teaspoon horseradish, and 1 teaspoon honey. Season with salt and freshly cracked black pepper to taste.
Prep your grill: Preheat your outdoor gas or charcoal grill to around 450°F. Ensure the grates are clean by brushing them and then lightly oiling to keep your burgers from sticking.
Grill the burgers: Grill each patty over direct heat for 3-4 minutes on each side, or until they reach your desired doneness. Once done, remove them from the grill and let them rest for a few minutes. While the patties are warm, top each with slices of brie.
Assemble the burgers: Spread some of the burger sauce on each toasted brioche bun. Nestle in the patties, topped with the remaining caramelized onions and a handful of arugula. Serve your French Onion Burgers immediately for the best experience!
Storing & Reheating
Leftover burgers can be stored at room temperature for up to two hours, or in the refrigerator for 3-4 days if placed in an airtight container. If you wish to freeze them, wrap each burger separately in plastic wrap and then aluminum foil for a maximum of 3 months. To reheat, simply pull them from the fridge and warm them on a grill or in an oven set to 350°F for about 10 minutes, or until heated through. Note that the texture might change slightly, but you can refresh it with some extra sauce when serving.
Chef’s Helpful Tips
- Be patient while caramelizing the onions; rushing can result in burning or uneven caramelization.
- Ensure your beef is well-chilled before forming patties; this helps maintain their structure while cooking.
- If grilling indoors or using a stovetop, consider a cast-iron skillet for excellent heat retention.
- For added flavor, sprinkle any remaining brie on top just before serving, so it melts slightly.
- These burgers can easily be prepped in advance; form the patties and store them in the fridge for a few hours before grilling.
- If you’re making these for a crowd, consider cooking the burgers in batches to avoid overcrowding the grill.

Recipe FAQs
What kind of beef is best for burgers?
The ideal beef for burgers is ground beef with a fat content of about 15%. This balance (like 85/15) keeps the burgers moist and flavorful while grilling. If you prefer leaner options, consider using ground turkey or plant-based meat that mimics beef.
Can I use a different cheese instead of brie?
Absolutely! If brie isn’t your favorite, feel free to swap it with grilled cheese, gouda, or Swiss. Each will add a unique flavor profile while still delivering the cheesy, creamy goodness perfect for these burgers.
How do I know when my burgers are done?
The best way to ensure your burgers are cooked to the perfect doneness is by using a meat thermometer. Medium burgers should read around 160°F in the center. Remember to let them rest for a few minutes before serving, as they will continue cooking slightly.
Can I make the caramelized onions in advance?
Yes, you can prepare the caramelized onions ahead of time! In fact, they can taste even better after a day in the fridge as the flavors meld. Just reheat gently before topping your burger patties!
