A vegan Reuben sandwich is the ultimate celebration of fermentation.  Practically everything in it is fermented! The sauerkraut, sourdough rye, and smoked tempeh. It’s also amazingly satisfying and delicious. Perfect when you need a quick hot meal.


Units Scale

Russian Dressing

  • 1/2 cup vegan mayonnaise
  • 2 Tbsp ketchup
  • 1 tsp Dijon mustard
  • 1/2 tsp finely chopped onion.



  1. Mix all of the ingredients for the Russian dressing in a small bowl.
  2. Place all the pieces of bread on a broiler-friendly baking pan. Toast under the broiler until they are just starting to brown. The exact timing will depend on the temperature of your broiler. Mine is about 3 minutes on high.
  3. Once the bread has toasted on one side, take the pan out of the oven and build the sandwiches. Spread a thin layer of Russian dressing on the toasted sides of the bread, so that both the top and bottom sides of the sandwich are covered.
  4. Cover the bottom slice of bread with a piece of tempeh, followed by 2 Tbsp of sauerkraut, and two slices of cheese.
  5. Place the second slice of bread on top of the cheese, with the Russian dressing side down. Then butter the top of the sandwich.
  6. Broil on low until the top of the bread is well-toasted. (About 3 minutes under my broiler).
  7. Serve immediately with a large fermented dill pickle and a handful of potato chips.


  • I’ve included my favorite vegan alternatives in the recipe above, however, feel free to replace them with your favorite option.
  • Swiss cheese is traditional in a Reuben sandwich, so if you’re a vegetarian feel free to replace the vegan cheese with Swiss cheese, and the margarine for butter.
  • If you are using frozen bread or tempeh (the best option for a quick dinner) expect the bread to take a bit longer to toast. And warm the tempeh up in a frying pan on the stove, while the bread toasts. Broiling won’t be enough to warm up frozen slices of tempeh.
