Ingredients
1 lb ground beef
4 slices of Swiss or Gruyère cheese
2 large yellow onions, thinly sliced
2 tablespoons unsalted butter
1 tablespoon olive oil
1 teaspoon sugar
1 teaspoon balsamic vinegar
4 hamburger buns, toasted
1 teaspoon fresh thyme leaves
Salt and pepper to taste
1 clove garlic, minced
Optional: 1/4 cup beef broth
Instructions
Step 1: Caramelize the Onions
Heat the Skillet: Begin by heating a large skillet over medium heat. Add 2 tablespoons of unsalted butter and 1 tablespoon of olive oil.
Add Onions and Seasonings: Once the butter has melted, stir in the thinly sliced onions, 1 teaspoon of sugar, and 1 teaspoon of balsamic vinegar. The sugar and vinegar help the onions attain a beautiful deep caramelization.
Cook the Onions: Cook the onions for about 20 minutes, stirring occasionally. You want them to become super soft and a rich, golden brown color. Patience here is key – don’t rush these beauties.
Add Garlic and Thyme: Next, sprinkle the onions with the minced garlic and 1 teaspoon of fresh thyme leaves, cooking for an additional minute or two until the garlic is fragrant. Remove from heat and set aside. If the mixture is very dry, you can add a splash of beef broth to deglaze the pan and add more flavor!
Step 2: Prepare the Patties
Form the Patties: While the onions are cooking, form the ground beef into 4 patties. Season each with a pinch of salt and pepper.
Heat the Grill Pan: Heat a grill pan or skillet over medium-high heat.
Cook the Patties: Cook the patties to your preferred doneness – about 4 minutes per side for medium-rare.
Add Cheese: In the final minute of cooking, place a slice of cheese on each patty and cover to melt the cheese. If cooking inside, you can also pop the skillet under a broiler for a quick melt.
Step 3: Assemble the Burgers
Toast the Buns: Toast the hamburger buns to your liking. A lightly toasted bun adds a nice texture and prevents it from becoming soggy.
Assemble: Place each cooked patty on the bottom half of a toasted bun. Top the patties generously with the caramelized onion mixture.
Finish: Cap it off with the top bun and serve these French Onion Soup Burgers piping hot.
Variations & Tips
Picky Eaters: If you’re catering to picky eaters, simply set some caramelized onions aside before adding the garlic and thyme to keep it simple for the kiddos.
Lighter Option: For a lighter option, use ground turkey instead of beef and opt for whole wheat buns.
Extra Flavor: For an extra pop of flavor, mix a little Dijon mustard or horseradish cream into your burger mix before forming the patties.
Rest the Patties: Always rest your patties for a few minutes after cooking to let those delicious juices redistribute.
Different Cheeses: Experiment with different cheeses like provolone or cheddar if you prefer a different flavor profile.
Conclusion
These French Onion Soup Burgers are a delightful twist on the classic hamburger, bringing a gourmet touch to your everyday meal. The caramelized onions provide a sweet and savory depth, while the melted Swiss or Gruyère cheese adds a creamy richness. The combination of these elements with a juicy beef patty and toasted bun creates a burger experience that is truly special.
