Ingredients
1 pound 85-percent lean ground beef
1 large egg, lightly beaten
1 medium yellow onion, 1/2 grated and 1/2 thinly sliced
1/2 teaspoon garlic powder
1 teaspoon kosher salt
1 teaspoon freshly ground black pepper
2 tablespoons unsalted butter, softened
12 slices white bread
12 slices American cheese, optional
Toppings (any or all):
Mustard
Ketchup
Sliced tomatoes
Pickles
Directions
- To make the burgers, combine the beef, egg, grated onion, garlic powder, salt and pepper in a medium bowl. Mix until combined and then form into 6 thin patties.
- Spread the butter on 1 side of each slice of bread. Heat a large, heavy-duty skillet or griddle over medium-high heat. Cook the burgers to desired doneness, about 3 minutes per side. Drain on paper towels. Drain the grease from the skillet.
- In the same skillet, place 6 slices of bread, butter-side down. Top each with a slice of cheese, if using, some sliced onions and a burger. Top with the remaining cheese, if using, and bread, butter-side up. Cook the sandwiches until golden brown, about 2 minutes per side.
- Serve with mustard, ketchup, tomatoes, pickles or any other desired hamburger toppings.
