How to Make the Recipe

Step 1: Prepare the Beef Patties

In a bowl, mix the ground beef with the French onion soup mix. Season with salt and pepper. Form the mixture into burger patties, making sure they are slightly larger than the croissants.

Step 2: Grill the Patties

Cook the patties on the grill or in a skillet over medium heat until they reach your desired doneness. Add a slice of Swiss cheese on each patty during the last minute of cooking, allowing it to melt.

Step 3: Caramelize the Onions

In a skillet, melt butter over medium heat. Add the sliced onions and sauté them until golden and caramelized, which should take about 10-15 minutes.

Step 4: Toast the Croissants

Slice the croissants in half and toast them in the oven or on a pan until they are golden brown and crispy.

Step 5: Assemble the Burgers

Place the cooked beef patty with melted Swiss cheese on the bottom half of each croissant. Top with the caramelized onions, then place the top half of the croissant on top to complete the burger.

Step 6: Serve and Enjoy

Serve the French Onion Croissant Burger immediately while the cheese is still melted and the croissant is crispy.

Tips for Making the Recipe

• Don’t Overcrowd the Skillet: When grilling the patties, avoid overcrowding the pan to ensure even cooking.
• Caramelize the Onions Slowly: Patience is key when caramelizing onions—low and slow heat ensures they develop their sweet, deep flavor.
• Toast the Croissants Just Right: Toast the croissants until golden and crispy, but be careful not to overdo it, as they can burn quickly.
• Use Fresh Ingredients: Fresh beef and croissants will elevate the taste of this burger significantly.

How to Serve

This burger is perfect for serving with crispy fries, a side salad, or even some onion rings for an extra indulgent treat. If you’re hosting a BBQ or a family dinner, this is an excellent option that will impress your guests.

Make Ahead and Storage

Storing Leftovers

If you have leftover patties or caramelized onions, store them separately in airtight containers in the refrigerator for up to 2 days. When ready to enjoy, reheat in the microwave or skillet.

Freezing

The beef patties can be frozen before cooking. Place them in an airtight container or freezer bag, and freeze for up to 3 months. Thaw them in the refrigerator overnight before cooking. Caramelized onions can also be frozen for up to 1 month.

Reheating

To reheat the burger, wrap it in foil and place it in a preheated oven at 350°F for 10-15 minutes. For a fresh crisp, you can toast the croissants again before serving.
