Ingredients
Burger
- 2 lbs. American Wagyu ground beef
- 4 brioche buns
- 4 generous slices of Gruyere cheese
- Onion jam
- Rosemary aioli
- Arugula
Rosemary Aioli
- ¾ cup good quality mayonnaise
- 1 1/2 tablespoons chopped fresh rosemary leaves
- 2 cloves garlic, minced
- 2 tablespoons fresh lemon juice
- 3/4 teaspoon salt
Red Onion Jam
- 2 large red onions (about 2 lbs.), cut into 1/8" slices
- 1 cup dry red wine
- 3 tablespoons canola oil
- 1/3 cup brown sugar
- 2 tablespoons balsamic vinegar
- 1/2 teaspoon fresh ground black pepper
- 1/2 teaspoons Kosher salt
Directions
Burger
- Cut brioche buns in half and brush each cut side with melted butter. Set aside.
- Divide ground beef into four equal portions (eight ounces each). Shape patties into uniform, but loosely packed burgers about an inch larger in diameter than the buns. Make a depression in the center of each patty. Right before placing on heat, season burgers on both sides generously with Kosher salt and fresh cracked black pepper.
- ON A GRILL: Turn gas grill to high or bring a charcoal to high heat (minimum of 600°F). Cook burgers on one side, then flip and continue cooking. Allow 3 minutes per side for medium rare or 4 minutes for medium. Top with Gruyere, close lid and allow to cook about one more minute or until the cheese is just melted. Remove burgers and place on platter.
- PREPARE IN A FRY PAN OR GRIDDLE: Heat a tablespoon of oil in the pan until hot. Place patties on hot surface and cook until brown and a nice crust forms, about 3 minutes. Flip the burgers and cook another 3 minutes for medium rare or 4 for medium. Top with Gruyere slices and cover for one more minute to let cheese melt. Remove burgers and place on platter.
- Place buns on grill or pan to toast. Remove and immediately build the burgers. Spread about 1 1/2 tablespoons aioli on bottom bun. Cover with a layer of arugula. Add patty and cheese. Place about 2 tablespoons onion jam on top and cover with the toasted bun top. Serve and enjoy!
Rosemary Aioli
- Mix mayonnaise, rosemary, garlic, lemon juice, salt, and pepper in a bowl. Cover and refrigerate for an hour or more before serving.
Red Onion Jam
- Heat canola oil in a skillet over medium heat. Add onions, season with salt and pepper, and cook until softened, about 5 to 8 minutes.
- Add wine, sugar and balsamic. Bring the contents to a boil, then reduce the heat to low. Simmer until liquid thickens, stirring occasionally. Taste and add additional salt and pepper if needed. Transfer finished jam to a bowl to cool. Use right away or store in the fridge until ready to use. Keeps for about 10 days.
