Ingredients Overview

1 lb ground beef: Choose 80/20 ground beef for the perfect balance of flavor and juiciness.

1 packet French onion soup mix: Adds an instant punch of savory onion flavor.

1/4 cup bread crumbs: Helps bind the patties together for a perfect texture.

1/4 cup beef broth: Keeps the burgers moist and enhances the beefy flavor.

1 tsp Worcestershire sauce: A dash of umami goodness that brings depth to the burger.

4 slices Swiss cheese: Creamy and slightly nutty, Swiss cheese melts beautifully over the patties.

4 hamburger buns: Opt for sturdy buns that can hold up to the juicy burger.

Salt and pepper to taste: Simple seasonings that bring out the natural flavors.


Step-by-Step Cooking Instructions

Step 1: Prepare the Burger Mixture
In a large mixing bowl, combine the ground beef, French onion soup mix, bread crumbs, beef broth, Worcestershire sauce, salt, and pepper. Mix gently but thoroughly until all ingredients are evenly incorporated.

Step 2: Form the Patties
Divide the mixture into 4 equal portions and shape into patties, ensuring they are slightly larger than the buns as they will shrink during cooking.

Step 3: Grill the Patties
Preheat your grill or skillet to medium-high heat. Cook the patties for about 4-5 minutes per side, or until they reach your desired level of doneness (use a meat thermometer if needed: 160°F for medium). Avoid pressing down on the patties to retain their juiciness.

Step 4: Add the Cheese
Place a slice of Swiss cheese on each patty during the last minute of cooking. Cover the grill or skillet to help the cheese melt evenly.

Step 5: Assemble the Burgers
Toast the hamburger buns lightly for added texture. Place each patty on a bun and serve immediately. Add your favorite toppings or keep it simple to highlight the French onion flavor.


Tips for the Perfect French Onion Soup Burgers

1. Don’t overmix the meat: Handle the beef mixture gently to avoid dense patties.

2. Use quality beef: Higher-fat content ensures a juicier burger.

3. Chill the patties before cooking: This helps them hold their shape on the grill.

4. Toast the buns: A lightly toasted bun adds a nice crunch and prevents sogginess.

5. Enhance with caramelized onions: Add caramelized onions for an extra layer of flavor.

6. Pair with a dipping sauce: Serve with a side of beef broth or onion soup for dipping to mimic the French onion soup experience.

7. Use a meat thermometer: Ensure perfectly cooked patties by checking the internal temperature.

8. Customize toppings: Lettuce, tomato, or a dollop of aioli can elevate the burger.

9. Let the patties rest: Allowing the patties to rest for a few minutes helps retain their juices.

10. Try brioche buns: Their slight sweetness pairs wonderfully with the savory burger.


Storage and Reheating Tips

Storing: Let leftover patties cool completely before transferring to an airtight container. Store in the refrigerator for up to 3 days.

Reheating: Reheat patties in a skillet over low heat or in the microwave for 30-second intervals until warmed through. Toast the buns for the best texture.

Freezing: Wrap uncooked patties individually in plastic wrap, then place in a freezer-safe bag. Freeze for up to 3 months. Thaw in the refrigerator before cooking.
