A Reuben Sandwich is a deli classic with crispy rye bread, melty Swiss cheese, tangy sauerkraut, and savory corned beef or pastrami, all topped with creamy dressing. Make it from scratch or use shortcuts—either way, it’s a flavorful, satisfying sandwich!
Prepare Corned Beef or Pastrami: Thinly slice cold corned beef or pastrami. I recommend using my homemade pastrami. If using homemade it’s much easier to slice when it is cold so that it doesn’t crumble.
Warm the meat through: You can reheat it if you'd like in a skillet, over medium heat with some of the drippings/cooking liquid. If using deli slices, use a little water or beef broth.
Assemble Reuben
Butter each slice of bread. Place 4 slices, butter side down on a cutting board (line with parchment paper for easy clean up)
Spread the slices with 1 tablespoon dressing and top with 2 slices of cheese, ¼ of the sauerkraut and ¼ of the corned beef.
Spread more dressing on the second piece of bread and place it on top of the sandwich, butter side out.
Place in a skillet over medium low heat and cook until just golden and crisp. Flip and cook the other side.
Cut in half and serve with additional dressing to dip, if you’d like.
Notes
Storage
Make-Ahead Tips: While Reubens are best fresh, you can prep ingredients ahead of time! Make the dressing up to two weeks in advance, slice and warm the meat, and drain the sauerkraut so everything is ready to assemble.Storage: If you have leftovers, store the sandwich wrapped in foil or an airtight container in the fridge for up to one day. Keep in mind, it won’t be as crispy when reheated, but it’ll still taste great!Reheating: Skip the microwave—it’ll make the bread soggy. Instead, warm the sandwich in a skillet over medium-low heat until crispy and heated through.
