Ingredients

  • 1 stick unsalted butter, softened
  • 6 tablespoons mayonnaise
  • 4 cups prepared macaroni and cheese, warmed
  • 2 onions, thinly sliced Kosher salt and freshly ground pepper
  • 1 cup barbecue sauce
  • 2 cups prepared pulled pork
  • 8 slices buttermilk or white bread
  • 12 slices sharp cheddar cheese (about 6 ounces)

Method

  • Put 6 tablespoons butter and the mayonnaise in the bowl of a stand mixer; beat with the paddle attachment until combined, scraping down the sides of the bowl as needed.
  • Set aside.
  • Spread the macaroni and cheese in an 8-inch-square baking dish to about 3/4 inch thick.
  • Cover with plastic wrap and chill until firm, about 45 minutes.
  • Cut the macaroni and cheese into squares that are slightly smaller than the bread slices.
  • Meanwhile, melt the remaining 2 tablespoons butter in a skillet over medium heat.
  • Add the onions and cook, stirring, until caramelized, about 20 minutes.
  • Season with salt and pepper.
  • Combine the barbecue sauce and pulled pork in a saucepan over low heat and cook until warmed through, about 5 minutes.
  • Generously spread the butter-mayonnaise mixture on one side of each bread slice.
  • Flip over half of the bread slices; layer 1 slice of cheddar, 1 macaroni-and-cheese square and another slice of cheddar on each.
  • Top each with one-quarter of the pulled pork and caramelized onions and another slice of cheddar.
  • Top with the remaining bread slices, buttered-side up.
  • Heat a large skillet or griddle over medium-low heat.
  • Working in batches, cook the sandwiches until the cheese melts and the bread is golden, about 5 minutes per side.
