How to Make French Onion Soup Burgers? 🥪

Follow these step-by-step instructions, and you’ll master the art of making French Onion Soup Burgers in no time!

Step 1: Mix the Beef Patties 🥩

Start by mixing the ground beef with salt, pepper, Worcestershire sauce, and garlic powder in a large bowl. Form the mixture into even-sized patties and set them aside.

Step 2: Caramelize the Onions 🧅

Melt butter in a pan over low to medium heat. Add sliced onions and cook slowly, stirring occasionally, until golden brown. Add in beef broth, thyme, and bay leaves. Simmer until the onions soften and soak up all those rich flavors.

Step 3: Cook the Patties 🍔

Heat your grill or stovetop pan. Cook the patties to your preferred doneness (medium is a solid choice). For the best flavor, add Swiss cheese slices on top during the last minute of cooking, allowing them to melt beautifully.

Step 4: Toast the Buns

Toast your burger buns either on the grill or in a toaster until lightly golden and crisp.

Step 5: Assemble the Burger 🥙

Place the patty on the bottom half of the bun, pile on plenty of caramelized onions, and carefully place the top bun. Serve immediately!

Tips for Making the Recipe

• Caramelization patience: Low and slow is the secret to perfectly caramelized onions. Avoid rushing this step.
• Cheese perfection: For melty, gooey cheese, add it to your beef patty in the last minute of cooking.
• Season patties evenly: Be generous when seasoning the raw beef mixture. A well-seasoned patty makes all the difference.
