How to Make French Onion Soup Burgers

Step 1: Caramelize the Onions

Begin by thinly slicing 3 to 4 large yellow onions. Heat butter and olive oil in a wide skillet over medium-low heat, then add the onions, stirring occasionally. This slow cooking process should take around 30 to 40 minutes until the onions turn a deep golden brown and develop their signature silky sweetness. Patience here is the key to building the rich, savory base of your French Onion Soup Burgers.

Step 2: Prepare the Beef Patties

While the onions are caramelizing, mix ground beef with salt, pepper, and a few fresh thyme leaves. Handle the meat gently and shape into evenly sized patties. Avoid overworking the meat to keep your burgers juicy and tender.

Step 3: Cook the Patties

Heat a grill or skillet to medium-high and cook the patties about 4 minutes per side for medium doneness. Right before they finish cooking, spoon some caramelized onions over each patty and top with slices of Gruyère cheese. Cover the pan or close the grill lid to melt the cheese perfectly.

Step 4: Prepare the Buns

Lightly toast your French rolls or brioche buns in a hot pan or oven to add a slight crunch and hold up against the juicy burger toppings.

Step 5: Assemble Your French Onion Soup Burgers

Layer the bottom bun with a spoonful of extra caramelized onions, then the cheesy beef patty, followed by any additional toppings you like. Finish with the top bun and get ready to indulge.

Pro Tips for Making French Onion Soup Burgers

• Go Low and Slow on Onions: Proper caramelization can take time; rushing will result in bitter, underdeveloped flavors.
• Use Quality Cheese: Gruyère melts beautifully and adds authenticity, but fresh, high-quality alternatives work too.
• Don’t Overmix Meat: To keep the patties tender, handle the ground beef lightly when shaping.
• Rest the Patties: Let the cooked burgers rest for a few minutes before assembling to retain juiciness.
• Toast the Buns: It adds texture and prevents sogginess from the onions and beef broth infusion.

How to Serve French Onion Soup Burgers

Garnishes

Side Dishes

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Keep any leftover caramelized onions and cooked patties separately in airtight containers in the refrigerator for up to 3 days to preserve freshness and prevent sogginess.

Freezing

French Onion Soup Burger patties freeze well. Freeze uncooked patties in a single layer on a baking sheet before transferring to a freezer bag for up to 3 months. Caramelized onions can also be frozen in small portions to save prep time later.

Reheating

Reheat patties gently in a skillet over medium heat to maintain juiciness. Warm caramelized onions in a small pan or microwave before assembling. To keep buns from getting soggy, toast them fresh before serving leftovers.
