- 1 1/2 tablespoons unsalted butter
- 1 small onion, thinly sliced
- kosher salt and freshly ground pepper to taste
- 1 teaspoon sugar
- 2 ounces deli-shaved pastrami/corned beef*
- 2 teaspoons Worcestershire sauce
- 1 tablespoon whole-grain mustard
- 4 slices Cooper® Sharp White cheese
- 4 slices pumpernickel or dark rye bread
The pastrami on rye is about as iconic as sandwiches get. Its roots go deep — created in 1888 at one of New York City’s first delis. Maybe that’s why it goes so great with Cooper® Sharp. Because Cooper’s been making mouths water itself since 1893. Put these two on a plate together and that’s more than 250 years of tasty history staring you in the face. That’s hard to argue with.

Directions
-
In a large skillet over low heat, melt 1/2 tablespoon butter. Add the onion, 1/2 teaspoon salt, and pepper to taste. Cook on low heat, stirring occasionally, until soft and golden, or about 20-25 minutes. Continue cooking, stirring occasionally, until the onions are extremely tender and the liquid is slightly syrupy, or about 8 more minutes. Remove from heat and stir in Worcestershire sauce and mustard. Transfer the onions to a small bowl and set aside.
-
In the same pan, add the pastrami and lightly crisp the meat until just warmed through. Remove from heat and set aside.
-
Lightly butter the outsides of all 4 pieces of bread. On the inside of the bread, divide half of the Cooper® cheese between 2 of the bread slices. Top each piece of bread with equal amounts of hot pastrami and onions. Top with the remaining cheese, then place the remaining 2 slices of bread on top of the Cooper® cheese, with buttered sides facing out.
-
Melt the remaining 1 tablespoon butter in a large skillet over medium heat. Add the sandwiches and cook, pressing occasionally with a spatula, until the bread is toasted and the cheese melts, or about 4 minutes per side. While cooking, add more butter to the pan if needed.
