Step‑by‑Step Instructions for French Onion Soup Burgers

Step 1: Prepare the Beef
In a mixing bowl, combine the ground beef with the Lipton onion soup mix, working it gently until well incorporated. Cover the mixture and let it sit for 10 minutes at room temperature to allow the flavors to meld, enhancing the savory taste of your French Onion Soup Burgers.

Step 2: Caramelize Onions
Melt 2 tablespoons of butter in a large skillet over medium heat. Add sliced onions and fresh thyme, stirring to coat evenly. Cook for about 15 minutes, stirring occasionally, until the onions soften and begin to turn golden brown. For extra depth, deglaze the pan with a splash of brandy or sherry, cooking for an additional 5 minutes until the onions are caramelized and fragrant.

Step 3: Form the Burgers
Shape the seasoned ground beef mixture into 6-ounce patties, making a slight indentation in the center of each patty. This helps them cook evenly and prevents bulging while grilling. Place the formed patties on a plate, cover, and refrigerate for about 10 minutes to firm up before cooking.

Step 4: Cook the Burgers
Heat a grill or a skillet over medium-high heat. Cook the burger patties for approximately 3-4 minutes per side, or until they reach your desired doneness, ideally medium-rare at 143°F. During the last couple of minutes, top each burger with the caramelized onions and a slice of Provolone or Gruyère cheese. Cover the grill or skillet with a lid to melt the cheese, which should take about 2 minutes.

Step 5: Toast Buns
While the burgers are cooking, brush the cut side of the onion buns with melted butter. Place them, buttered side down, on a separate skillet or on the grill for about 2 minutes until they’re golden brown and toasted to perfection. This adds a delightful texture that complements the juicy burgers.

Step 6: Assemble and Serve
Once the burgers are cooked and the cheese has melted beautifully, it’s time to assemble. Place each juicy French Onion Soup Burger on a toasted bun, layering extra caramelized onions on top if desired. Serve your delicious creations immediately, savoring the rich flavors of your homemade meal!

Tips for the Best French Onion Soup Burgers

Onion Caramelization: Watch closely while caramelizing onions; stir occasionally to prevent burning and achieve that sweet, golden color.
Burger Indentation: Always create a slight dent in the center of each burger patty. This ensures even cooking and prevents puffing as they grill.
Cooking Temperatures: For perfect doneness, use a meat thermometer. Aim for 143°F for medium-rare French Onion Soup Burgers, adjusting cooking time based on preference.
Cheese Melting: Cover the burgers with a lid during the last minutes of cooking to trap heat, ensuring the cheese melts beautifully over the caramelized onions.
Batch Cooking: Consider making extra caramelized onions; they freeze well and can save prep time for future meals while enhancing flavor!

Classic Coleslaw: The crunch and tangy flavor of coleslaw act as a refreshing counterbalance, cutting through the creaminess of the melted cheese.
Sweet Potato Wedges: Roasted wedges add a hint of sweetness and texture, complementing the natural flavors of the caramelized onions.
Refreshing Green Salad: A light salad with mixed greens, tomatoes, and a zesty vinaigrette provides a break from the heartiness of the burgers, enhancing the experience.

French Onion Soup Burgers Recipe FAQs

What type of onions work best for caramelizing?
Yellow or sweet onions are ideal for caramelizing in this recipe. They have a naturally higher sugar content that caramelizes beautifully, creating that rich, sweet flavor essential to your French Onion Soup Burgers.

How should I store leftover burgers?
Store your French Onion Soup Burgers in an airtight container in the fridge for up to 3 days. If you want to enjoy them later, they can be frozen for up to 3 months. Just make sure to wrap the patties individually in plastic wrap and place them in a zip-top bag to avoid freezer burn.

Can I freeze the caramelized onions?

They can last up to 3 months in the freezer. When you’re ready to use them, simply thaw overnight in the fridge and reheat in a skillet.

What if my burgers come out dry?
If you find your burgers are dry, it often comes down to cooking time or overworking the meat. To prevent this, mix the ground beef with the Lipton onion soup mix gently, and avoid compacting the patties too tight. Always cook them to the recommended medium-rare temperature of 143°F and consider using 75% lean ground beef for that juicy texture.

Are there any dietary considerations for pets or allergies?
Yes! If you’re making these burgers for a gathering, be aware of common allergens in the ingredients, such as gluten in the onion buns and dairy from the cheese. For pets, avoid giving them any cooked onions as they can be toxic. Adjust the recipe to accommodate dietary restrictions, such as using gluten-free buns or opting for dairy-free cheese alternatives.
