How to Make French Onion Soup Burgers

Making French Onion Soup Burgers is a straightforward process that involves layering flavors step by step. Here’s how to bring this delicious recipe to life:

Step 1: Caramelize the Onions

1. Heat 2 tablespoons of butter and 1 tablespoon of olive oil in a large skillet over medium heat.
2. Add the thinly sliced yellow onions and a pinch of salt. Cook for 20-25 minutes, stirring occasionally, until the onions are golden and caramelized.
3. Stir in 1 clove of minced garlic and 1/2 teaspoon of dried or fresh thyme. Cook for an additional 1-2 minutes.
4. Deglaze the skillet with 1/4 cup of beef broth, scraping up any browned bits from the bottom of the pan. Simmer for 2-3 minutes until the liquid reduces slightly. Remove from heat and set aside.

Step 2: Prepare the Burger Patties

• In a large mixing bowl, combine 1 pound of ground beef with salt, pepper, and 1 teaspoon of Worcestershire sauce (optional). Mix gently until just combined.
• Divide the beef into 4 equal portions and shape into patties about 3/4-inch thick. Make a slight indentation in the center of each patty to prevent puffing while cooking.

Step 3: Cook the Burger Patties

1. Heat a grill, grill pan, or skillet over medium-high heat. Lightly oil the surface to prevent sticking.
2. Cook the patties for 3-4 minutes on one side until browned. Flip and cook for another 3-4 minutes or until the internal temperature reaches 160°F for a medium burger.
3. During the last minute of cooking, top each patty with a slice of Gruyère cheese. Cover the pan or grill to let the cheese melt.

Step 4: Toast the Bread or Buns

1. While the patties are cooking, lightly butter your French bread slices or burger buns. Toast them on a skillet or in the oven until golden and crisp.

Step 5: Assemble the Burgers

1. Place the toasted bread or bun bottoms on plates.
2. Add a burger patty topped with melted Gruyère cheese.
3. Generously spoon the caramelized onions over the patty.
4. Top with the second slice of bread or bun, or leave it open-faced for a more rustic presentation.

Step 6: Serve and Enjoy

Serve the burgers immediately with a side of fries, salad, or soup for a complete meal. Every bite will remind you of the comforting flavors of French onion soup!

How Long to Cook Burger Patties

The cooking time depends on how thick your patties are and how well-done you like them. Here’s a quick guide for cooking burgers to the ideal temperature:

• Medium-Rare: Cook 2-3 minutes per side, internal temp 130-135°F
• Medium: Cook 3-4 minutes per side, internal temp 140-145°F
• Medium-Well: Cook 4-5 minutes per side, internal temp 150-155°F
• Well-Done: Cook 5-6 minutes per side, internal temp 160°F

Using a meat thermometer ensures that your patties are cooked to perfection every time.

How to Store Leftovers

• Refrigerator: Store leftover patties and caramelized onions in airtight containers for up to 3 days. Reheat gently on the stove or in the microwave.
• Freezer: You can freeze cooked burger patties (without cheese) by wrapping them tightly in plastic wrap and storing them in a freezer-safe container for up to 2 months. Thaw in the fridge before reheating.

Cooking Tips

1. Caramelizing the onions takes patience—low and slow is the key! Stir occasionally to avoid burning and let the natural sugars develop for the best flavor.
2. Don’t overwork the meat when forming patties. Mixing too much can result in tough burgers. Handle gently for tender, juicy patties.
3. Toast the bread or buns to keep them from getting soggy and to add a nice crunch to every bite.
4. Let the burgers rest for a few minutes after cooking to seal in the juices.

Variations

• Vegetarian Option: Use plant-based burger patties and vegetable broth for the onions.
• Low-Carb Version: Serve the patties with caramelized onions on a bed of greens instead of bread.
• Extra Flavor Boost: Add a thin layer of Dijon mustard or a smear of garlic aioli to the bread before assembling.

With these tips in mind, you’ll be enjoying restaurant-quality French Onion Soup Burgers at home like a pro!
