Step‑by‑Step Instructions for French Onion Burgers

Step 1: Prepare Patties
In a large mixing bowl, combine 1 pound of 85% lean ground beef with 1 packet of dry onion soup mix, 2 tablespoons of Worcestershire sauce, and a pinch of salt. Gently mix the ingredients until just combined to avoid overworking the meat, which ensures juicy French Onion Burgers.

Step 2: Shape Patties
Divide the mixture into four equal parts and shape each into a burger patty, about ¾ inch thick. Create a slight indentation in the center of each patty to prevent puffing while grilling. This ensures even cooking and uniform thickness, which is essential for the best burger experience.

Step 3: Preheat Grill
While shaping the patties, preheat your grill over medium-high heat for about 5 minutes. Make sure the grill grates are clean and lightly oiled to prevent sticking. The grates should be hot enough to create a nice sear on the patties, giving the French Onion Burgers that delicious charred exterior.

Step 4: Grill Patties
Carefully place the patties on the preheated grill. Close the lid and grill for about 3-4 minutes on each side. Look for a nice brown sear to form, which indicates they’re ready to flip. This grilling time creates a perfectly juicy interior while infusing each burger with smoky flavor.

Step 5: Add Cheese (if using)
During the last minute of grilling, add a slice of cheese on top of each patty after flipping. Close the lid again to melt the cheese, which typically takes about 1 minute. Opt for Swiss or cheddar for that rich flavor that complements the savory taste of the French Onion Burgers.

Step 6: Toast Buns (optional)
If desired, place the brioche buns, cut side down, on the grill for about 1 minute until lightly toasted. They should turn golden brown, offering a lovely crunch and enhancing the overall burger experience. Toasting adds texture and helps hold in the juices from the patty.

Step 7: Assemble Burgers
Once the patties are cooked, remove them from the grill and let them rest for a couple of minutes. To assemble your French Onion Burgers, place each patty on a toasted bun and top with your favorite additions such as crispy bacon, caramelized onions, dijonnaise, or any other toppings you prefer. Serve immediately for the best flavor and warmth!

Flavor Boost: Marinate the patties in a mixture of soy sauce and garlic overnight; this adds an extraordinary depth of flavor to each bite.
Herb-Infused: Mix fresh herbs such as basil or thyme into the ground beef for an aromatic twist that pairs beautifully with the onions.

Expert Tips for French Onion Burgers

Perfect Patty Shape: Ensure your patties are uniformly thick, with a slight indentation in the center, to prevent puffing while grilling.
Rest for Juiciness: Allow the cooked patties to rest for a couple of minutes before assembling your French Onion Burgers; this helps retain moisture for a delicious, juicy bite.
Avoid Overworking: When mixing your meat, be gentle! Overworking can lead to tough burgers, so mix just until combined.
Monitor Grill Temperature: Preheat your grill properly! A hot grill creates that beautiful sear, sealing in flavor and juices.
Don’t Squish: Resist the temptation to press down on the burgers with a spatula while cooking. This keeps the patties juicy and flavorsome.
