Ingredients
1 teaspoon olive oil
1 small red onion, thinly sliced
Coarse salt and ground pepper
1 teaspoon sugar
2 tablespoons red-wine vinegar
1 garlic clove, minced
3 tablespoons mayonnaise
1 1/2 pounds ground beef chuck (80 percent lean)
8 split brioche or soft dinner rolls
Preparation
In a medium skillet, heat olive oil over medium-high. Add onion, and cook until softened, 2 minutes. Season with salt and pepper. Add sugar and vinegar; toss to coat. Let mixture cool. In a small bowl, combine garlic and mayonnaise.
Heat a grill to medium-high. Clean and lightly oil hot grill. Divide ground beef into 8 balls. Press each lightly to form 3/4-inch-thick patties. Season each with salt and pepper. Grill 3 minutes per side for medium. Serve sliders on rolls with pickled onions and garlic mayonnaise.
