We have a deliciously tangy and oniony spread, lots of zesty sauerkraut, roasty toasty bread, and a thinly sliced homemade seitan that is very very delicious. Meet my vegan reuben!



  • Vegan Italian-Style Seitan
  • Vegan Thousand Island Dressing:
    • 1/2 cup vegan mayo
    • 2 and 1/2 tablespoons sweet onion, minced
    • 1 tablespoon ketchup
    • 1 small (2-inch) dill pickle, minced (about 3 tablespoons)
    • 1/2 teaspoon sugar
    • 1/2 teaspoon lemon juice
    • 1/4 teaspoon granulated garlic
    • 1/2 teaspoon smoked paprika
    • salt and pepper, to taste


  • your chilled seitan, sliced thin
  • two slices of rye bread
  • a few spoonfuls of your thousand island dressing
  • 12 slices of vegan cheese (optional)*
  • a few spoonfuls of sauerkraut
  • oil, for toasting


  1. The day before: Make your seitan (recipe here) and your thousand island dressing.
  2. To make the dressing, mix all of your ingredients together in a container. Fit with a lid and allow to chill overnight.
  3. Reuben day: After slicing your seitan, warm it up in a dry pan over medium heat until no longer cold. If you’re using vegan cheese, go ahead and toss that on top of the seitan as its warming so it melts.
  4. Meanwhile, take a slice of your bread and spread it with some of your thousand island dressing. Top it with your warmed seitan, cheese, and sauerkraut. Top it with another slice of bread and give it a slight press to compact everything.
  5. Add a drizzle of oil in your warm pan and add your sandwich, cooking until brown and toasty, 2-3 minutes. Carefully flip your sandwich, and continue cooking on that side, adding more oil if necessary, until both sides of the bread are browned.
  6. Slice diagonally in half (optional, but arguably the best way to serve a sandwich) and dive in!


* I haven’t found a vegan cheese I like, so I leave it off and I don’t feel like I’m missing anything. That said, a traditional reuben is served with swiss cheese, so if you can find a vegan swiss, try that!
