Mushroom Reuben Sandwich

The classic Reuben sandwich goes vegan in this savory recipe. Layers of flavorful mushrooms, tangy sauerkraut, and creamy Thousand Island style dressing make for a delicious meal you’ll be dreaming about for a long time!

Serves 4 


  • 16 ounces Portobello or white mushrooms
  • 2 teaspoons oil
  • 1/2 teaspoon ground cumin
  • 1 teaspoon fennel seed (optional)
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon black pepper
  • 1/8 teaspoon salt
  • 8 slices dark or light rye bread
  • 4 slices of vegan sliced cheese
  • 1/2 cup sauerkraut (choose lowest sodium version available)
  • Home made thousand island dressing, (recipe below)
    • 3 tablespoons vegan mayo
    • 1 tablespoon ketchup
    • 1 tablespoon sweet pickle relish
    • ½ teaspoon vinegar


  1. Preheat oven to 375. Line a baking sheet with parchment paper or foil or spray with nonstick spray.
  2. Clean and slice mushrooms ¼ – ½ inch thick. Place cut mushrooms in a bowl and drizzle with oil. Toss. Add cumin, fennel seeds (if using), garlic powder, black pepper, and salt. Toss again.
  3. Spread sliced mushrooms on the prepared baking sheet in a single layer. Place mushrooms in the oven and cook for about 10-12 minutes. Remove from oven, flip mushrooms, and return for 10-12 additional minutes. Remove from oven when slightly browned and set aside.
  4. Assemble each sandwich by layering on one slice of bread: a slice of cheese, 1/4th of the roasted mushrooms, 2 tablespoons sauerkraut, and 1/4th of the thousand island dressing. Top with the second slice of bread, cut in half, and enjoy!


  • Try toasting your bread before adding the fillings for a slightly crunchy experience.
  • When choosing your sauerkraut, ketchup, and pickle relish, look for versions with the lowest amount of sodium available.
  • Turn this into a “Reuben Philly” by using a hoagie roll instead of rye bread. You can also add fresh or sautéed bell peppers and onion to bring even more flavor to your sandwich.
