- 1 shallot, minced
- 1 teaspoon olive oil
- 1 pound ground sirloin
- 1 pound ground chuck
- 1 tablespoon salt
- 1 teaspoon freshly ground black pepper
- 2 tablespoons Worcestershire sauce
- 1 tablespoon Dijon mustard
- 2 tablespoons finely chopped fresh sage leaves
- 5 eggs
- 1/4 cup whole milk
- 1 teaspoon salt
- 1/2 teaspoon freshly ground black pepper
- 6 Portuguese muffins, halved
- 4 tablespoons butter
- 6 slices Gruyere cheese
- 6 slices prosciutto
Saute shallot in olive oil over medium-low heat until softened. Set aside to cool.
To make patties combine ground sirloin, ground chuck, salt, pepper, Worcestershire sauce, mustard, sage, and sauteed shallot in a large bowl. Mix well until all ingredients are thoroughly combined. Divide mixture into 6 equal portions and form patties (6 ounces each). Grill patties (in grill pan) over medium-high heat for 4 minutes on each side for medium rare.
While patties are cooking, prepare buns. Whisk eggs in a bowl with milk, salt, and pepper. Dip Portuguese muffin halves in mixture 1 at a time (place each on a plate after dipping). Heat 1 tablespoon butter in saute pan over medium heat. Place 3 muffin halves into pan and fry, flipping once until both sides are golden brown. Place cooked muffins onto plate and cover with foil. Repeat process using 1 tablespoon butter for every batch of 3 muffin halves until all have been cooked.
