Method: French Onion Burgers

Step 1: Caramelize the Onions
In a large skillet, heat the olive oil and butter over medium heat. Add the sliced onions and cook, stirring occasionally, until they are golden brown and caramelized, about 20-25 minutes. Stir in the balsamic vinegar and dried thyme, and cook for an additional 2 minutes. Remove from heat and set aside.
Step 2: Prepare the Sauce
In a small bowl, combine the mayonnaise, Dijon mustard, and minced garlic. Mix well and set aside.
Step 3: Make the Burger Patties
In a large mixing bowl, combine the ground chuck and the packet of dry French onion soup mix. Mix gently until just combined, being careful not to overwork the meat. Divide the mixture into four equal portions and shape them into patties.
Step 4: Cook the Burgers
Preheat your grill or grill pan over medium-high heat. Cook the burger patties for about 4-5 minutes on each side, or until they reach your desired level of doneness. During the last minute of cooking, top each patty with shredded gruyere cheese and close the grill lid to melt the cheese.
Step 5: Assemble the Burgers
To assemble, spread a generous amount of the prepared sauce on the bottom half of each brioche bun. Add a handful of baby arugula, followed by the cheesy burger patty, and top with the caramelized onions. Place the top half of the bun on and serve immediately.

Meal Prep & Storage Notes
If you want to prep these burgers ahead of time, you can prepare the caramelized onions and the sauce a day in advance. Store them in airtight containers in the refrigerator. You can also shape the burger patties and keep them in the fridge until you’re ready to grill. Once cooked, leftover burgers can be stored in the fridge for up to three days. Reheat in the microwave or on the grill, adding a bit of cheese to melt if desired.
Your Questions, Answered
Can I use a different type of cheese?
Absolutely! While gruyere cheese is traditional, you can swap it for Swiss, provolone, or even cheddar if you prefer. Each will give a different but equally delicious flavor.
How do I know when my burgers are done cooking?
The best way to check for doneness is to use a meat thermometer. For medium-rare, aim for an internal temperature of 130-135°F, and for medium, cook until it reaches 140-145°F.
Can I make these burgers on the stovetop instead of the grill?
Yes! You can easily cook them in a skillet over medium-high heat. Just be sure to let the skillet get hot before adding the patties to get a nice sear.
What should I serve with French Onion Burgers?
These burgers pair wonderfully with sweet potato fries, a fresh garden salad, or even a bowl of Cheeseburger Soup for a complete meal.
