Warm panini with sautéed Granny Smith apples, Black Forest ham and Gruyère cheese.
Ham, Gruyère, and Apple Panini
2 tablespoons unsalted butter, at room temperature
2 Granny Smith apples, peeled, cored, and sliced ¼ inch thick
1 tablespoon chopped fresh thyme leaves
8 (½-inch-thick) slices country-style white bread
½ cup whole-grain mustard
2 cups (8 ounces) shredded Gruyère cheese
8 (1-ounce) slices Black Forest ham
In a 12-inch skillet, melt the butter over medium heat. Add the apple slices and thyme. Cook, stirring occasionally, until the apples are slightly soft, about 4 minutes. Cool for 5 minutes. Preheat a panini press (see Cooks Note).
Spread each bread slice with 1 tablespoon mustard. Arrange ¼ cup of cheese on each of 4 of the bread slices and top each with 2 slices of ham. Divide the apple mixture evenly over the ham. Add the remaining cheese and place the remaining 4 bread slices, mustard side down, on top.
Grill until the cheese has melted and the tops are golden and crispy, 5 to 6 minutes.
Cooks Note: If you dont have a panini press or indoor grill, use a grill pan. Preheat it before adding the sandwiches, weighting them down on top with a heavy pan, such as a cast-iron skillet. Be sure to flip the sandwiches halfway through cooking to brown the second side of them.
