This vegan reuben with mandolined portobello is a delicious and indulgent sandwich! Paper-thin portobello slices are marinated then baked to create a crispy and chewy texture. They are then piled high onto toasted rye bread slices with melted vegan cheese, sauerkraut, cabbage, and reuben dressing. Bring plenty of napkins!
If you’ve ever wilted spinach, you know that the amount you begin with is waaaaay more than the amount you end up with. This is kind of like that, but with mushrooms. What’s lost in volume is gained in texture: these shriven petals are perfect for packing into a reuben with sauerkraut and dousing with some awesome sauce.
How to make a vegan reuben sandwich
Reubens are definitely not vegan, but it’s easy to recreate the meaty texture and flavor using plant-based ingredients. Reuben dressing is super easy to veganize. Vegan Worcestershire and mayo are easy to find or make. Add some dill pickle and a squirt of hot sauce (or ketchup if you hate spicy), and you’ve got vegan reuben dressing! Vegan cheese is easy to find, but select one that’s melty, like Daiya Swiss-style slices or Violife brand slices. Toasting the bread is absolutely essential not only for this reuben, but for vegan burgers and hot dogs. That buttery crunch is so good!Print

for the mushrooms
- 1 lb portobello mushroom caps, sliced on a mandoline
- 1 cup vegetable broth
- 2 tsp garlic powder
- 2 tsp steak seasoning
- 1 tsp smoked paprika
- 1 TB olive oil, or enough to grease a large baking sheet
for the sauce
- 1/2 cup vegan mayo
- 3 TB chopped dill pickles
- 1 TB sriracha
- 1 tsp vegan Worcestershire sauce
- rye bread + some oil or vegan butter
- vegan cheese (gouda, provolone, swiss, etc.) I like Follow your Heart, Violife or Daiya brands
- handful of mandolined red cabbage
to prepare the mushrooms
- combine the sliced mushrooms with the broth and spices. Allow to marinate for at least an hour to overnight. Stir once or twice during marinating to coat.
- When ready to make the sandwiches, preheat oven to 300. Place a fine meshed strainer or sieve over a bowl and press with another to get most of the liquid out. Break up with your hands and press again until almost dry.
- Transfer to a greased baking sheet in an even layer. Bake for 15-20 minutes, then stir around, baking for 10-15 more, or until mushrooms are dried out a bit, but not crispy.
- Transfer to paper towels in an even layer and set aside.
to prepare the sauce
- Combine all sauce ingredients and set aside.
- Slightly toast the bread with a little oil or vegan butter in a cast iron pan, layering some vegan cheese over to slightly melt.
- Layer the sandwich with sauerkraut, raw cabbage, mushrooms and sauce. Serve immediately.
