Caramelize the Onions:
- In a large sauté pan, heat olive oil and butter over medium heat.
- Add the sliced onions and cook, stirring occasionally, until they soften and turn golden brown (about 20-25 minutes).
- Stir in balsamic vinegar during the last 5 minutes of cooking, allowing it to reduce and glaze the onions. Season with salt and pepper to taste. Remove from pan and set aside.
Prepare Special Sauce:
- In a mixing bowl, combine ketchup, mayonnaise, yellow mustard, and hot sauce. Mix well until smooth and creamy. Adjust the amount of hot sauce to your spice preference. Set aside.
Cook the Wagyu Beef Patties:
- Preheat your grill or a large skillet/griddle over medium-high heat.
- Lightly season the Wagyu patties with salt and pepper.
- Cook patties for about 3-5 minutes per side for medium doneness, or until they reach your desired level of doneness. Remember, Wagyu beef is rich, so it’s best not to overcook them.
Toast the Brioche Buns (Optional):
- While the patties are cooking, lightly butter the cut sides of the brioche buns.
- Toast them on the grill or in a dry pan until golden brown.
Assemble the Burgers:
- Spread a generous amount of special sauce on both the top and bottom halves of each bun.
- Place a butter lettuce leaf on the bottom bun.
- Add the cooked Wagyu beef patty on top of the lettuce.
- Pile a generous amount of caramelized onions on top of the patty.
- Add 2-3 slices of vine-ripened tomatoes.
- Cover with the top half of the brioche bun.
Serve:
- Serve the burgers immediately with your favorite sides.
