Ingredients:

To create the ultimate French Onion Soup Burgers, you’ll need the following ingredients:

For the Onions:

  • 4 large yellow onions, thinly sliced
  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • 1 teaspoon sugar
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 1/4 cup beef broth
  • 1/4 cup dry white wine (optional)
  • 2 teaspoons fresh thyme, chopped (or 1 teaspoon dried thyme)

For the Burgers:

  • 1 1/2 pounds ground beef (preferably 80/20 blend)
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 tablespoon Worcestershire sauce
  • 4 slices Gruyere cheese (or Swiss cheese)
  • 4 brioche buns, toasted
  • 4 tablespoons mayonnaise (optional)
  • Fresh thyme for garnish

Instructions:

Step 1: Caramelize the Onions

  1. Prepare the Onions: In a large skillet, melt the butter with the olive oil over medium heat. Add the sliced onions and stir to coat them evenly.
  2. Cook the Onions: Sprinkle the onions with sugar, salt, and pepper. Cook, stirring occasionally, for about 30-40 minutes or until the onions are golden brown and caramelized. If the onions start to stick, add a splash of beef broth or water to deglaze the pan.
  3. Deglaze and Flavor: Once the onions are caramelized, add the beef broth and white wine (if using). Stir in the thyme and cook for an additional 5 minutes until the liquid has mostly evaporated. Remove from heat and set aside.

Step 2: Prepare the Burgers

  1. Mix the Beef: In a large bowl, combine the ground beef with salt, pepper, and Worcestershire sauce. Mix gently until just combined.
  2. Form the Patties: Divide the beef mixture into four equal portions and shape them into patties, making a slight indentation in the center of each patty to prevent them from puffing up during cooking.
  3. Cook the Patties: Heat a grill or skillet over medium-high heat. Cook the patties for about 4-5 minutes per side, or until they reach your desired level of doneness. During the last minute of cooking, place a slice of Gruyere cheese on each patty and cover to melt the cheese.

Step 3: Assemble the Burgers

  1. Toast the Buns: While the patties are cooking, toast the brioche buns until golden brown.
  2. Build the Burgers: Spread a tablespoon of mayonnaise on the bottom half of each bun (if using). Place the cooked patties with melted cheese on the buns, then top each patty with a generous amount of caramelized onions. Sprinkle with fresh thyme for garnish.
  3. Serve: Top with the other half of the buns and serve immediately. Enjoy your French Onion Soup Burgers with a side of crispy fries or a fresh salad.

Serving and Storage Tips for French Onion Soup Burgers:

Serving Tips:

  1. Presentation Matters: Serve your French Onion Soup Burgers on a wooden board or a nice plate to enhance their gourmet appeal. Garnish with fresh thyme sprigs for an extra touch of elegance.
  2. Pair with Sides: Complement the rich flavors of the burgers with sides like crispy French fries, sweet potato fries, or a fresh green salad. A side of creamy coleslaw or roasted vegetables also pairs well.
  3. Condiments and Toppings: Offer additional condiments like Dijon mustard, aioli, or a garlic herb spread. For a crunchy texture, consider adding crispy fried onions or pickled red onions.
  4. Drink Pairings: For an elevated dining experience, pair these burgers with a robust red wine like Cabernet Sauvignon or a Belgian-style beer. For non-alcoholic options, a sparkling water with a twist of lemon or a classic iced tea works well.
  5. Keep it Warm: If serving a crowd, keep the burgers warm in a low oven (around 200°F) while you finish preparing the sides. This ensures everyone enjoys their meal hot and fresh.

Storage Tips:

  1. Refrigeration:
    • Onions: Store leftover caramelized onions in an airtight container in the refrigerator for up to 4-5 days.
    • Patties: Cooked burger patties can be stored in an airtight container in the refrigerator for up to 3-4 days. Separate layers with parchment paper to prevent sticking.
    • Buns: Keep brioche buns in a resealable bag at room temperature for 2-3 days or in the refrigerator for up to a week.
  2. Freezing:
    • Onions: Freeze caramelized onions in an airtight container or freezer bag for up to 3 months. Thaw in the refrigerator overnight before reheating.
    • Patties: Freeze cooked patties individually wrapped in plastic wrap and then place in a freezer bag for up to 3 months. Thaw in the refrigerator overnight.
    • Buns: Brioche buns can be frozen in a resealable freezer bag for up to 3 months. Thaw at room temperature before toasting.
  3. Reheating:
    • Onions: Reheat caramelized onions in a skillet over medium heat until warmed through, adding a splash of water or broth if they appear dry.
    • Patties: Reheat burger patties in a skillet over medium heat for 3-4 minutes per side or in a 350°F oven for 10-15 minutes. Avoid using the microwave as it can make the patties tough.
    • Buns: Refresh brioche buns by lightly toasting them in a toaster or oven at 350°F for a few minutes.
  4. Avoid Sogginess: Store burger components separately (patties, onions, buns) to prevent sogginess. Assemble just before serving for the best texture and flavor.

FAQ’s About French Onion Soup Burgers:
