This Tempeh Reuben Sandwich is my go-to when I want a hearty twist on a deli classic without meat. It delivers all the tangy sauerkraut flavor and melty cheese goodness you love in a Reuben but swaps the corned beef for savory, seasoned tempeh. It is so satisfying and makes for a quick lunch or cozy dinner that even meat lovers crave.

I first whipped this up for my husband when we were snowed in and missing our favorite takeout sandwiches. He declared it better than the original and now asks for it every time we get fresh rye bread.

Ingredients

  • Tempeh eight ounces: This is full of protein and soaks up savory flavors Look for organic or non GMO brands for the best texture
  • Soy sauce or tamari one tablespoon: Adds umami depth You can use gluten free versions if needed
  • Smoked paprika one teaspoon: Gives the tempeh a gentle smoky bite Use Spanish paprika if possible for extra flavor
  • Salt half teaspoon: Balances out the other flavors Use sea salt or kosher salt
  • Olive oil one tablespoon: Allows for golden crispy edges Choose extra virgin for a richer taste
  • Sourdough rye bread four slices: The classic base for a Reuben Denser breads hold up best to saucy fillings
  • Reuben sauce or whole grain mustard one to two tablespoons: Adds creaminess and punch You can mix up a quick homemade sauce with mayo ketchup and paprika
  • Swiss cheese or smoked mozzarella or provolone or melty vegan cheese Two slices: Melts beautifully and brings that gooey texture Choose a cheese that melts well
  • Sauerkraut half to three quarter cup: Provides tangy crunch Use fresh or local kraut for the brightest taste

For Quick Reuben Sauce

  • Mayonnaise or vegan mayo quarter cup: Makes the sauce creamy and rich
  • Ketchup or tomato paste one tablespoon: Brings sweetness and tang Ketchup keeps it classic
  • Paprika half teaspoon: Adds color and warmth
  • Lemon juice or vinegar one teaspoon: Brightens and balances the sauce Use lemon for a fresh twist

Step-by-Step Instructions

Prep the Tempeh:
Slice the tempeh in half lengthwise then cut each piece in half again crosswise so you have four thin rectangles. Place them in a saucepan and cover with water. Add soy sauce salt and smoked paprika. Cover and simmer for ten minutes. This removes bitterness and loads the tempeh with flavor. Drain and gently pat dry with a towel.
Make the Reuben Sauce:
While the tempeh simmers whisk together mayo ketchup paprika lemon juice salt and pepper in a small bowl. Add garlic or horseradish if desired. Taste and adjust if you like more tang or spice.
Sear and Melt:
Heat olive oil in a saute pan over medium high. Place the simmered tempeh pieces in the hot pan and sear each side for two to three minutes until they are crisp and golden. Turn down the heat and lay a slice of cheese over each piece of tempeh. Cover the pan until the cheese melts and the slices look glossy.
Toast the Bread:
While the cheese melts you can toast the bread either in a toaster or wipe out the pan and toast in olive oil for more golden crunchy edges.
Assemble the Sandwich:
Spread Reuben sauce or mustard on all slices of toasted rye. Layer sauerkraut evenly over the bottom bread slices. Add the cheesy seared tempeh. Cap with remaining bread sauce side down. Slice in half for easier eating if you like.

I never get tired of the smoky aroma from the paprika whenever I make this The first time my son tried this sandwich he asked for seconds and now it is a weekend lunch tradition

Storage Tips

Keep leftover sandwiches assembled and wrapped in wax paper or foil in the fridge They taste great cold but to reheat simply grill or press in a hot pan for two to three minutes on each side To store extra tempeh or Reuben sauce separately pack in airtight containers where they will keep for up to four days

Ingredient Substitutions

Tempeh can be swapped with firm pressed tofu or your favorite vegan deli slices Try a sharp aged cheddar or a dairy free alternative if you cannot find Swiss Do not be afraid to pile on extra kraut or use a spicy whole grain mustard in place of sauce

Serving Suggestions

Serve your Reuben with classic deli sides such as pickles potato chips or a handful of crisp apple slices For a dinner plate pair with tomato soup or a simple green salad This sandwich is hearty enough to stand alone but you can also cut it into quarters for party sliders

14 Salt and black pepper to taste
15 Optional: 1 minced garlic clove or pinch garlic powder
16 Optional: Prepared horseradish
17 Optional: Splash of Worcestershire sauce or soy sauce

Steps

Step 01

Slice the tempeh in half lengthwise, then cut each half crosswise to yield four thin rectangles. Place the pieces in a saucepan, add enough water to cover, soy sauce, salt, and smoked paprika. Cover and simmer for 10 minutes. Drain and pat the pieces dry.

Step 02

In a small bowl, whisk together mayonnaise, ketchup, paprika, lemon juice or vinegar, salt, and pepper. For added depth, blend in garlic, horseradish, and a splash of Worcestershire or soy sauce if desired.

Step 03

In the same pan, wipe dry and heat olive oil over medium-high. Sear tempeh slices on each side until deeply golden and crisp, approximately 2–3 minutes per side. Reduce heat, add cheese slices atop the tempeh, and cover until the cheese is thoroughly melted. Remove from heat.

Step 04

Toast the sourdough rye slices either in a toaster or in the skillet with a touch of olive oil until golden and crisp.

Step 05

Generously spread Reuben sauce or mustard on all bread slices. Layer tempeh, sauerkraut, and top with the remaining bread. Slice each sandwich in half if desired and serve warm.

Notes

  1. Simmering tempeh before searing removes bitterness and infuses flavor.
