The combination of ingredients may seem strange, but you're just going to have to trust me on this one: it's really good. This vegetarian reuben is inspired by the veggie reuben from Trapeze Pub in Athens, Georgia, where I went to college.
I originally shared this recipe in 2018 while I was living in Portland and missing Athens. Now I just love this recipe and make it whenever I'm craving a hot vegetarian sandwich!
Of course, this is not a classic reuben because we're using pickled cabbage in place of corned beef, but it does have some of the key ingredients: horseradish sauce, swiss cheese and rye bread.
The result? A flavor-packed, filling vegetarian sandwich packed with a bunch of healthy plant-based ingredients.
Main ingredients
- Spicy, tangy, horseradish sauce is made with Greek yogurt, preserved horseradish, ketchup and a few other pantry staples. Preserved horseradish is usually found in the condiments aisle and is not the same as horseradish cream.
- Sliced tomatoes and spinach add color and flavor. They aren't a part of traditional reubens, but like I said, this isn't exactly a traditional reuben.
- Sliced swiss cheese is a must!
- Quick pickled cabbage is a great meat replacement because it's packed with flavor and has crisp but tender texture.
- Rye bread: I always have trouble finding rye bread at my store so I go for dark rye bread, which is just as delicious. Sourdough rye is even better if you can find it.
Quick pickled cabbage
Pro tip: Prepare the cabbage up to a week in advance to make this a super quick meal. Keep refrigerated in a closed container until ready to use.
Quick pickling is one of those things that seems intimidating but is surprisingly very, very easy to do. Check out my quick pickled onions for even more tips on quick pickling.
Combining sliced red cabbage with vinegar, salt and sugar causes it to tenderize while keeping some of its crunch. It also adds a punch of acidity and saltiness to the sandwich.
I use a combination of red wine vinegar and apple cider vinegar for flavor but white vinegar will work in a pinch.
I use a gallon sized Ball jar (like these but I bought them second hand) for this recipe. Quart sized jars work but you will need to divide the cabbage and brine between two quart sized jars. A tupperware container or even a large bowl also works.
- Simply combine all brine ingredients in your jar. Place the lid on top and shake until the sugar is dissolved. If using a bowl, just whisk until the sugar and salt are dissolved.
- Slice the cabbage into ½ inch strips. Break apart the pieces with your hands. Add to the jar with the brine. Use a mixing spoon or whisk to push down the cabbage so that its completely covered. Add water as needed so that the cabbage is completely covered.
- Let rest at least 2 hours, but ideally 4 hours before using. The longer its pickled the more tender and marinated the cabbage will be.
Putting it all together
Make the horseradish sauce by mixing together all sauce ingredients in a small bowl until well combined. This is a creamy, zesty sauce. Don't let the ingredients fool you: it is super good!
Making the sandwiches is simple but I like to layer the ingredients so that you get a taste of each ingredient in every bite.
A sandwich/panini press is perfect for this sandwich, but the stove also works.
If using the stove, make a makeshift press using a weighted plate or pan on top of the sandwich. This helps the sandwich get nice, flat and melded together with the swiss cheese.
Recipe FAQ
I find that it keeps best in the fridge for up to 2 weeks. After that it starts to soften and lose its texture.
You can replace the Greek yogurt with vegan mayo and the swiss cheese with your favorite vegan style swiss.
Tempeh bacon is definitely the move! You can also add sautéed tofu or enjoy some crispy chickpeas on the side.

- 1 tablespoon unsalted butter
Instructions
Quick Pickled Cabbage
- Slice the red cabbage into ½ inch strips. In a one gallon mason jar (or divide between two quart sized jars) mix together water, vinegar, salt, and sugar until dissolved. I usually put the lid on the jar and shake to dissolve everything.
- Add cabbage and garlic, mashing down the cabbage so that it is fully covered with liquid. Add an extra splash of water if needed. Refrigerate for at least 2 hours and ideally 4 hours.
Horseradish Sauce
- Add all ingredients to a small bowl, whisking to combine.
Vegetarian Reubens
- Instructions for one sandwich on panini press: Preheat panini press to medium high heat*. Remove ½ cup pickled cabbage from container. Pat the cabbage with a paper towel to remove excess liquid. Spread two tablespoons of horseradish sauce on one side of the bread, then stack with ½ sliced tomato, ½ cup pickled cabbage, ½ cup spinach and two slices of Swiss cheese. Close the sandwich and heat on panini press until golden brown, about 3-5 minutes.
- Instructions for stove top: Heat a skillet over medium heat. Once hot, add a pat of butter or oil. Once melted, add the sandwich cheese side down. Cook until golden, about 2 minutes, then flip. Place a pan or heat safe plate on top of the sandwich and push down so that everything is mushed together. Cook another minute with the plate on top. Enjoy immediately.
Notes
- Vinegar: I like the red wine vinegar and apple cider vinegar combo for its flavor and light sweetness but white vinegar will work in a pinch.
- Leftovers: Keep cabbage refrigerated in a closed container for up to 2 weeks.
