Hey everyone, Jason Griffith here! We all have those moments when we’re craving the deep, savory flavors of French onion soup, but what we really want is a juicy burger. This French Onion Soup Burgers recipe is the perfect solution. It’s a genius mashup that takes all the best parts of both dishes—the sweet, caramelized onions, the rich broth, the melted Gruyère cheese, and a perfectly cooked beef patty—and puts them all in a bun. This is a burger that’s so good, you’ll be dreaming about it long after you’ve had the last bite.

Why I Love This Recipe

What I love most about this recipe is how it captures the essence of French onion soup in a completely new and exciting format. The patient, slow caramelization of the onions is the key to the entire dish, creating a deep, sweet flavor that is the perfect complement to the savory ground beef. The melted cheese on top adds that classic, irresistible gooeyness, and the a touch of rich beef broth brings it all together in a perfect, messy bite. This recipe is a fantastic way to impress your friends and family with a creative and delicious meal that’s a true celebration of comfort food.

Ingredients

• 1 lb ground beef
• 2 large onions, thinly sliced
• 2 tablespoons butter
• 1 tablespoon olive oil
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 cup beef broth
• 1 teaspoon Worcestershire sauce
• 4 slices Gruyère cheese
• 4 burger buns, toasted

Swaps and Notes

• Ground Beef: I prefer a ground beef with a fat content of 80/20 for the juiciest burgers. You can use a leaner beef, but you might want to add a splash of olive oil to the pan when you cook the patties.
• Onions: Yellow onions are the best for caramelizing, as they have a higher sugar content.
• Cheese: Gruyère is the classic choice for French onion soup, and its nutty flavor and fantastic melt are perfect here. Swiss cheese would also be a good substitute.
• Buns: A sturdy brioche bun or a ciabatta roll would work well and stand up to the rich toppings.

Step-by-Step Instructions

1. Caramelize the Onions: In a large skillet or Dutch oven, melt the butter and olive oil over medium-low heat. Add the thinly sliced onions and a pinch of salt. Cook for 20-30 minutes, stirring occasionally, until the onions are soft, golden brown, and beautifully caramelized. This step takes patience, but it is the most important part of the recipe!
2. Make the Burger Patties: While the onions are caramelizing, gently form the ground beef into four equal patties. Season both sides with salt and black pepper.
3. Finish the Onions: Once the onions are caramelized, add the beef broth and Worcestershire sauce to the skillet. Stir, scraping up any browned bits from the bottom of the pan. Let the liquid simmer and reduce for about 5 minutes, until it has thickened slightly. Set the onions aside.
4. Cook the Burgers: In the same skillet, or a separate one, cook the burger patties over medium-high heat for 3-4 minutes per side for medium-rare, or longer for your desired doneness.
5. Assemble and Melt: During the last minute of cooking, top each burger patty with a generous amount of the caramelized onions, then a slice of Gruyère cheese. Cover the skillet with a lid and let it sit for about 1 minute, or until the cheese is completely melted and gooey.
6. Serve: Place the cheesy, onion-topped patties on toasted buns and serve immediately.

Tips for Success

• Low and Slow on the Onions: Don’t rush the caramelization of the onions! Low heat is key to getting that deep, sweet flavor without burning them.
• Don’t Overwork the Beef: When forming the patties, be gentle. Overworking the meat can make the burgers tough.
• Rest the Burgers: While not as critical as a steak, letting the patties rest for a minute or two after cooking can help them stay juicy.
• Use a Good Skillet: A heavy-bottomed skillet or Dutch oven is perfect for this recipe as it retains heat well and cooks everything evenly.

Serving Suggestions and Pairings

These French Onion Soup Burgers are a meal in themselves. They’re rich, savory, and incredibly satisfying. You can serve them with a simple side of potato chips or a fresh green salad to add some freshness. For a fun party spread, they would go perfectly with other cheesy, indulgent snacks like Easy Cheesy Chicken Sliders with Marinara Garlic Butter or with a platter of sheet pan quesadillas.
