Sweet Potato Reuben Sandwich (Vegan)

This Sweet Potato Reuben Sandwich will blow your mind. Roasted sweet potatoes, sauerkraut, and homemade vegan Thousand Island on delicious rye bread. A plant-based masterpiece that’s healthy, easy, and oil-free!

  • Total Time: 35 minutes
  • Yield: 2 sandwiches 1x


Units Scale
  • 1 large sweet potato, peeled and thinly sliced lengthwise
  • 4 slices of any oil-free whole grain bread (I used rye bread)
  • 1/2 cup saurekraut
  • 1/2 cup vegan Thousand Island Dressing

Spice Mix For Sweet Potato Reuben

  • 1 tablespoon ground mustard seeds
  • 1 tablespoon ground coriander
  • 1 tablespoon dried thyme or oregano
  • 1 tablespoon ground black pepper
  • 1/2 teaspoon crushed red pepper
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon ground ginger
  • 1/8 teaspoon ground cloves


To Cook The Sweet Potatoes

  1. Add all of the spices to a small bowl and mix them together.
  2. Preheat your oven to 400˚F and line a baking sheet with parchment paper.
  3. Thinly slice the sweet potato lengthwise. I used a mandoline slicer on the thinnest setting.
  4. Toss the sweet potato slices in a little low-sodium vegetable broth or water and then lay them out on the baking sheet. Sprinkle the spice mixture over each slice of the sweet potatoes then flip and repeat. Place the sweet potatoes in the oven and bake for 20-30 minutes until cooked through and tender. Cook on the longer side if you want a bit of a char.

To Make The Sandwich

  1. Heat a nonstick skillet or grill pan over medium-high heat.
  2. Generously spread some of the vegan Thousand Island dressing on each slice of bread, add 1/2 of the sweet potato slices on the bottom slice, and top with sauerkraut. Place the last piece of bread on top and set the sandwich in the pan.
  3. Cook the sandwich until each side is golden brown and crunchy, flipping occasionally to avoid burning.
  4. Once the sandwich is finished cooking, transfer to a plate, slice in half, and enjoy!
  5. Serve with fat-free microwave potato chips and pickle spears.


I used marble rye for this recipe but use your favorite oil-free whole grain bread.

The sodium tends to be a bit higher in this recipe because it’s such a large portion and the condiments. If you wish to lower the sodium you can cut the portions in half or use a lesser amount of the fixings.
