Heat 1 tablespoon of olive oil and 1 tablespoon of butter in a large skillet over medium heat. Add the thinly sliced onions and a pinch of salt. This helps them cook evenly. Stir the onions often. They need about 15-20 minutes to caramelize. For perfect caramelization, keep an eye on the heat. Too high, and they burn. Too low, and they won't brown. Add 1 teaspoon of sugar halfway through to enhance the sweetness. In the last few minutes, stir in 1 teaspoon of thyme. This adds a nice flavor. Now, let’s work on the burger patties. In a mixing bowl, combine 1 pound of ground beef with salt and pepper. Mix it gently. You want to keep the meat loose for a juicy burger. Shape the mixture into 4 equal patties. Make them about 1 inch thick. You can cook these patties on a grill or a skillet. Preheat your grill or skillet over medium-high heat. Cook each patty for 4-5 minutes per side. This gives you a medium burger. If you like it more done, just add a minute or two. Once your patties are done, it’s time to assemble. Start with the toasted burger bun. Spoon some of the onion and beef broth mixture on the bottom half. Place the cheese-topped burger patty on top. Use 1 slice of Swiss cheese per patty. Ensure that cheese melts by covering the burger with a lid for the last minute of cooking. Next, add more onion mixture on top of the patty. Finish with the top half of the bun. That’s it!

This helps the onions cook slowly and evenly. Stir them often to avoid burning. Aim for about 15 to 20 minutes to reach that golden brown color. Make sure to add a pinch of salt and a teaspoon of sugar. This helps with the caramelization. Choosing the right broth can change the taste of your burger. Use a rich beef broth for a deep flavor. If you want a lighter touch, try chicken broth. You can also add more seasoning to enhance the taste. Try adding garlic powder, or even a splash of Worcestershire sauce for extra depth. When cooking your burgers, know your doneness levels. A medium burger is juicy and pink inside. A well-done burger has no pink and is firmer. Use a meat thermometer to check the temperature. Aim for 160°F for medium and 170°F for well-done. This ensures your burger is safe to eat while keeping it moist. {{image_2}} You can use many different cheeses on your French onion soup burgers. While Swiss cheese is classic, try Gruyère for a nutty taste. Cheddar adds sharpness, while fontina brings creaminess. Feel free to mix and match cheeses for extra flavor. To make a vegetarian version, swap out the beef patties for plant-based ones. Look for patties made from beans, lentils, or mushrooms. For the broth, use vegetable broth instead of beef broth. This keeps the rich taste while making it meat-free. Get creative with toppings! Consider adding sautéed mushrooms or crispy bacon for texture. You can also drizzle balsamic glaze or add fresh arugula for a peppery kick. For sides, try sweet potato fries or a simple salad. These add balance to your hearty meal. To keep your French Onion Soup Burgers fresh, store them properly. First, let them cool down. Place the burgers in an airtight container. You can keep them in the fridge for up to three days. If you want to save them longer, freezing is a great option. Wrap each burger tightly in plastic wrap, then put them in a freezer bag. They can last for about three months. When you’re ready to enjoy leftovers, reheating is key. The best way to reheat a burger is in the oven. Preheat your oven to 350°F (175°C). Place the burgers on a baking sheet and cover them with aluminum foil. Heat for about 10-15 minutes. This method keeps the buns from getting soggy. If you're in a hurry, you can use the microwave too. Heat for about 30 seconds, but remember, the texture may change. If you love planning ahead, meal prep is a smart choice. You can cook the onions and beef broth a day before. Store them in separate containers in the fridge. The next day, just shape the patties and cook them as needed. For quick assembly, you can toast the buns while the burgers cook. This saves time and keeps everything fresh. Enjoy the ease of making this dish any day!

1 tablespoon butter

1 teaspoon sugar

1 teaspoon thyme (fresh or dried)

Salt and pepper to taste

4 slices Swiss cheese

4 burger buns, toasted

Fresh parsley for garnish (optional)

Instructions
 

Cook the Onions: In a large skillet, heat the olive oil and butter over medium heat. Add the sliced onions, salt, and sugar. Sauté the onions for 15-20 minutes or until they are caramelized and golden brown, stirring occasionally. Add the thyme during the last few minutes of cooking.

    Prepare the Broth: Once the onions are caramelized, add the beef broth to the skillet and let it simmer for about 5 minutes, allowing the flavors to meld. Taste and adjust seasoning if necessary. Remove from heat.

      Shape the Patties: In a mixing bowl, combine the ground beef with salt and pepper. Form the mixture into 4 equally sized burger patties.

        Cook the Burgers: Preheat a grill or skillet over medium-high heat. Cook the patties for about 4-5 minutes on each side for medium doneness, or until they reach your desired doneness.

          Melt the Cheese: In the last minute of cooking, place a slice of Swiss cheese over each burger, cover the grill or skillet to help the cheese melt.

            Assemble the Burgers: On each toasted bun, spoon some of the onion and beef broth mixture on the bottom half. Place the cheese-topped burger patty on top, followed by more onion mixture. Finish by adding the top half of the bun.

              Serve: Optionally, garnish the burgers with fresh parsley for an added touch of flavor and color.
