- 8 slices Jewish-style rye bread, divided (I used dill rye)
1 pound sliced corned beef
8 ounces sliced mild Italian Fontina cheese
1/2 sweet onion, thinly sliced
4 tablespoons (1/2 stick) butter, divided
- Place 4 bread slices on work surface. Spread mustard on 1 side of each. Divide corned beef among bread slices. Top with cheese and onion. Cover with remaining 4 bread slices, pressing slightly to adhere.
- Melt 2 tablespoons butter in each of 2 large nonstick skillets over medium heat. Place 2 sandwiches in each skillet and cook until golden brown on bottom, pressing occasionally with spatula, about 3 minutes. Turn sandwiches over and cook until golden on bottom and cheese melts, about 3 minutes. Transfer sandwiches to plates, cut in half, and serve.
