Ready to upgrade your burger game? French Onion Chicken Burgers are a savory, mouth-watering burger loaded with caramelized onions and rich Gruyere cheese. These burgers will taste like you ordered them straight from your favorite burger restaurant!
HOW TO CARAMELIZE RED ONIONS
The caramelized onions are really the star of this French onion burger. The thing is, true caramelized onions take time. I’ll be honest, this isn’t a quick sauté and I wouldn’t call this a quick weeknight dinner. It’s a process of about 40 minutes and you can’t rush it, or you’ll end up with onions that aren’t really the caramelized version.
Step 1. Slice the onions. I like to go quite thin with my onions to really get them nice and caramelized and browned.
Step 2. Melt the butter and oil together in the Dutch oven.
Step 3. Add the onions and cook for 40-45 minutes, alternating between low and medium-low heat and stirring frequently. The longer you let them cook the deeper the color you’ll get. I find that around 45 minutes is the sweet spot for me but you could cook these on low for 50-60 minutes.
For me the real magic starts to happen after 30 minutes. You’ll see around the 15 minute mark the onions are soft and translucent. After 30 minutes you should have some nice browning and fond at the bottom of the Dutch oven. I cooked my onions for 45 minutes to get a deep brown color.
HOW TO MAKE THE FRENCH ONION BURGERS
Once the onions are made the rest of the recipe is a breeze!
Step 1. Season the ground chicken and form into 4 equal patties.
Step 2. Heat olive oil in a pan, then add the chicken burgers and cook for 6 minutes.
Step 3. Flip the burgers and cook an additional 5 minutes.
Step 4. When there’s 2 minutes of cook time left on the burgers, add the slices of Gruyere and cover to allow the cheese to melt.
Serve by topping with arugula and the onions. I typically don’t add a sauce, but a garlic aioli would be delicious on these!
I recommend getting a digital meat thermometer. I used it in this recipe and I use it pretty much anytime I’m cooking chicken. It will help prevent over or under cooking meat.

Ingredients
For the Onions
2 red onions, sliced thin
2 tablespoons butter
1/2 tablespoon olive oil
1 tablespoon white wine (optional)
1/4 teaspoon white sugar
1/8 teaspoon salt
For the Burgers
1lb ground chicken
1/2 cup shredded Gruyere cheese
2 cloves of garlic, grated
1 tablespoon Worcestershire sauce
3 tablespoons chicken broth
2 teaspoons garlic powder
1 and 1/2 teaspoons dried thyme
1/2 teaspoon onion powder
1/2 teaspoon salt
1/4 teaspoon pepper
Sliced gruyere cheese
Olive oil
Arugula
4 brioche buns
Instructions
1. Start by making the caramelized onions. Add the butter and oil to the Dutch oven and heat over medium heat until the butter is melted. Pour in the onions, add the salt, then stir until all the slices are well coated in the butter and oil mixture and there are no slices sticking together. Reduce heat to medium-low. Cook the onions for 40-45 minutes, stirring frequently and alternating the heat between medium-low and low so that the onions don’t burn. Stir frequently so each slice has a chance to be in direct contact with the bottom of the pot. If there are any stubborn slices that aren’t browning I remove them with tongs. In the last 5 minutes of cooking, if you’d like add the sugar and a bit of liquid like white wine to deglaze the pot. Remove the onions to a plate and set side until the burgers are done.
2. While the onions are cooking, prepare the chicken burgers. Add the ground chicken to a large bowl and season with the garlic powder, onion powder, dried thyme, salt, and pepper. Add the Worcestershire sauce, shredded Gruyere, chicken broth, egg, and panko. Mix well so everything is combined, the mixture will be wet but still manageable. Form into 4 equal patties.
3. To a large pan add a tablespoon of olive oil and heat over medium heat. Add the burger patties, pressing down in the center of each to prevent them from puffing up. Cook on one side for 6 minutes.
4. Flip the burgers and gently press down with your spatula to flatten each burger. Cook for an additional 5 minutes. In the last 2 minutes of cook time, add slices of Gruyere to each burger then cover the pan to allow the cheese to melt. After 5 total minutes the burgers should be done at this point with an internal temperature of 165 degrees. If temperature is not reached add a tablespoon of water to the pan and cover again, cook in additional 30 second increments until the burgers are done.
To serve, top the burgers with the caramelized red onions and arugula. I don’t add sauce, but a garlic aioli would be delicious on these!
