Melted Camembert Burger with Caramelized Onions
This burger was born on an evening when I had a camembert waiting in the fridge and an irresistible craving for something indulgent. The cheese melting over the juicy patty, the sweet caramelized onions — it's the kind of recipe that makes you forget about restaurant burgers forever. I make it every time I want to impress guests.
🛒 Ingredients
4 servings
- 4 beef burger patties, 150g each (15% fat)
- 1 whole camembert, cut into 4 slices
- 3 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon brown sugar
- 2 tablespoons balsamic vinegar
- 4 brioche burger buns
- 4 leaves curly lettuce
- 2 tomatoes, sliced
- 4 tablespoons whole-grain mustard
- Salt and freshly ground black pepper
- A drizzle of olive oil
Directions
- 1
Start with the caramelized onions: melt the butter over medium heat in a large pan, add the sliced onions with a pinch of salt and cook for 25 minutes, stirring regularly, until golden and soft.
- 2
Add the brown sugar and balsamic vinegar to the onions, mix well and reduce for another 5 minutes over low heat. Set aside.
- 3
Season the patties generously on both sides with salt and pepper. Heat a drizzle of oil in a cast-iron skillet or grill pan over high heat.
- 4
Cook the patties for 2 to 3 minutes per side for a medium cook. In the last minute, place a slice of camembert on each patty, cover the pan and let the cheese melt slightly.
- 5
Toast the split brioche buns cut-side up under the broiler for 2 minutes.
- 6
Assemble: spread whole-grain mustard on the bottom bun, add lettuce, the patty with melted camembert, a generous portion of caramelized onions, tomato slices and close with the top bun.
💡 Chef's Tip
The secret to the onions is patience — never raise the heat to speed things up or they'll burn. For the camembert, choose one at room temperature; it will melt much better than cold cheese straight from the fridge.
