Ruben Sandwiches on a platter with homemade Russian dressing

Who doesn’t love a Reuben? Slathered with our homemade riff on Russian dressing, these classic Reuben sliders are always a hit.

Bite-Sized is Best!

At least when it comes to appetizers, we want one-or-two bite nibbles, and ideally ones that don’t require any utensils. These pastrami-loaded party sliders are a shrunk-down version of our favorite sandwich—the Reuben. Slices of dark rye bread are slathered with our homemade reuben sauce—basically homemade, sriracha-spiked Russian dressing—and piled high with pastrami, provolone cheese, and sauerkraut. Easy to make (thanks, sheet pan!) and delightful to eat, Reuben sliders are a party food slam-dunk.

A Tangy, Perfect Reuben Sauce to Write Home About.

Some people prefer to drench their Reuben in thousand island, and others are firmly devoted to Russian dressing. As for us? We say why choose? Our homemade Reuben sauce recipe combines the best of both worlds for a slightly sweet, tangy dressing with a spicy kick. Here is what you need:

  • Mayonnaise.
  • Ketchup.
  • Sweet relish.
  • Sriracha! Always.
  • Grated onion—yep, grated! Just a little grated into the dressing for texture and a bit of sharpness.
  • Fresh garlic cloves.

How Do You Make a Reuben Sandwich?

Say hello to your new favorite way to make hot sandwiches for a crowd—baked on a sheet pan! Just assemble them right on the pan, and bake until the bread is toasty and the cheese is melted. Here’s how to make the best reuben sandwich there ever was:

  1. Cut the bread and lay it on a baking sheet.
  2. Spread generously with that glorious homemade secret sauce.
  3. Load the bread with all the things! Pastrami, cheese, sauerkraut. Pro tip! If your sauerkraut is super liquidy, squeeze a little of that liquid out before adding the kraut to the sandwich. This will help to keep the bread from getting soggy.
  4. Slip those open-face sliders in oven until the cheese is melty and bubbling.
  5. Top with remaining bread slices and pop them back in to finish toasting.
  6. Serve! Heads up—these go FAST. You might want to be ready to make another tray full of them.

Reuben Sliders

  • Serves: 16
  • Prep Time:  20 min
  • Cook Time:  10 min
  • Calories: 214


  • 8 slices marbled rye bread
  • 4 slices provolone cheese
  • 1 lb pastrami, sliced thin for sandwiches
  • 1 cup sauerkraut, strained
  • 2 tbsp butter, melted


  • 1 cup mayonnaise
  • 1/4 cup ketchup
  • 1/3 cup sweet relish
  • 3 tbsp Sriracha sauce
  • 2 tbsp fresh squeezed lemon juice
  • 1 tbsp onion, grated
  • 1 clove garlic, minced
  • 1/2 tsp kosher salt
  • 1/4 tsp fresh ground pepper


  1. Turn oven on to 400° F.
  2. Mix all ingredients for the dressing in a small bowl. Set aside.
  3. Cut all 8 slices of bread into quarters. Place ½ of the bread slices (16 total) on 2 baking sheets. Spread each bread quarter with a generous amount of dressing.
  4. Divide pastrami evenly among the bread (about 1 ½ slices per slider.)
  5. Top pastrami with 1 tablespoon sauerkraut.
  6. Cut cheese slices into quarters. Place one quarter cheese on top of each sandwich.
  7. Toast sliders in oven, until cheese is melted. (This should only take a few minutes, so keep a close eye on them.)
