Ingredients

  • 1 small red onion, chopped
  • 1 tablespoon olive oil
  • 1-1/4 teaspoons salt, divided
  • 1/2 cup mayonnaise
  • 1/2 teaspoon whole peppercorns, crushed
  • 1-1/2 pounds ground beef
  • 4 kaiser rolls, split and toasted
  • Optional ingredients: tomato slices and lettuce leaves

Directions

  1. Place onion on a greased baking sheet. Drizzle with oil and sprinkle with 1/4 teaspoon salt; toss to coat. Bake at 400° for 8-12 minutes or until tender. Cool slightly. In a small bowl, combine the mayonnaise, crushed peppercorns and onion mixture; set aside.
  2. Sprinkle beef with remaining salt; gently mix. Shape into four patties. In a large skillet, cook patties over medium heat for 6-8 minutes on each side or until a thermometer reads 160° and juices run clear. Serve on rolls with mayonnaise mixture and, if desired, tomato and lettuce.
