Ingredients

Classic Fillings

  • 30 ounces (850g) leftover brisket
  • ½ cup (80g) pickled jalapeños
  • ½-1 red onion, thinly sliced
  • 1 cup (270g) BBQ sauce
  • 6 slices cheese (any melty cheese like cheddar, Colby, Jack, and Provolone)
  • 6 buns or 12 slices of bread (see notes)
  • 1 tablespoon (14g) unsalted butter

Optional Toppings

  • caramelized onions
  • coleslaw
  • horseradish sauce
  • sliced avocado

Instructions

Reheating Brisket in the Oven

  • Preheat the oven to around 325°F (163°C) and place the leftovers in an oven-safe baking dish.
  • Then add a little liquid (beef broth, pineapple juice, or BBQ sauce) to moisten the brisket.
  • Cover the baking dish to keep the meat from drying out, and place it in the preheated oven.
  • Heat the brisket for 15-20 minutes until heated through, being careful not to overcook it.

Reheating Brisket on the Stovetop

  • Heat a cast-iron skillet (or whatever skillet you have) on medium and add a little oil or butter.
  • Next, add the chopped brisket and cook for a few minutes until heated through, stirring as needed. Add broth for moister brisket if desired.

The Sandwiches

  • If toasting the buns, preheat a skillet over medium heat. Slice the buns in half, lightly butter them, and put them cut side down on the grill or skillet. Toast them for 1-2 minutes until they become lightly golden and crisp.
  • Take the bottom half of the bun and lay it down on a plate or cutting board.
  • Add a layer of sliced brisket on the bread, covering the surface evenly.
  • Drizzle BBQ sauce over the brisket and distribute it evenly.
  • Add your desired toppings. Close the bun and enjoy your BBQ brisket sandwich!

Notes

  • If the leftover brisket is slightly dry, add a bit of barbecue sauce, beef broth, or au jus before assembling the sandwich.
  • The recipe calls for 6 buns or 12 slices of bread for a medium sandwich. If you put less meat, you can make more sandwiches, and, of course, more meat makes fewer sandwiches.
  • Layer the ingredients starting with the heaviest first. The brisket slices, then the BBQ sauce, horseradish, mustard, etc., then the cheese, caramelized onions, and pickles. Finish it with the fresh greens or your favorite sliced veggies for a refreshing crunch.
  • Please remember that the nutritional data is a rough estimate and can vary greatly based on the products used in the recipe.
