A Vegetarian Reuben Sandwich Obsession
I’m completely smitten with this sauerkraut sandwich. I mean, shall I say, obsessed? I never thought in my meat-eating days I’d one day be enjoying a sandwich made with roasted beets. But here we are!
The best sandwiches are vegetarian and vegan, anyway, so I’m thrilled to find veggie packed sammies on the menu at when I visit a sandwich shop.
It was at The Greenbank Pantry, Whidbey Island, where I discovered the holy grail of a Vegetarian Reuben Sandwich on a cold rainy day on the way down to the Farmers Market. It’s like remembering your first kiss, or first car. This sauerkraut sandwich is everything I want it to be! A triumph.
This Veggie Reuben Is
- Super simple to Whip Up
- Hearty and Satisfying
- Meal Prep Ready
- Tangy, Saucy and Flavorful

Let’s Make the Sauce
All About the Sauce!
It’s similar to a Russian sauce, somewhat like Thousand Island but different because it’s a bit spicy. Now, another Russian dressing sauce I’ve tried incorporated horseradish, but I like the flavor of Sriracha more-so for this recipe. Best of all, it’s made pretty much with pantry staples.
In a small bowl, whisk all the ingredients together. It lasts a long time in the fridge, so you can have it on the ready when your sandwich cravings call.
- Dijon Mustard – adds a salty, vinegary flavor.
- Sriracha – offers a just a hint of spice. Add more or less to taste.
- Mayo – for an egg free Russian Dressing use vegan mayo – I like Follow Your Heart.
- Black Pepper – for more spice and interest.
- Ketchup – adds a little sweet and richness.
- Dill Pickles – for crunch and that pickle flavor we crave!
- Worcestershire Sauce – look for a vegetarian and vegan variety. I like Annie’s and The Wizzards.
About the Key Ingredients
With just a few simple ingredients, veggie reuben nirvana is right here.
- Really good bread. Go for a sturdy sourdough rye or a Seedy Sourdough. The sturdier, the better so that the sandwich stands up to the moist layers of ingredients.
- Roasted Beets, sliced thin. They add texture, structure and sweetness to this sammie. I have a super simple beet roasting method if needed.
- Sauerkraut. I like homemade with caraway seeds. For prepared kraut, look for Pickled Planet or Bubbies.
- Swiss Cheese. Adds melty texture and sharp flavor. I’ve also made this sammie with Gruyere or Emmental with good results.
- The Sauce adds sweetness, moisture, dill pickle flavor with a bit of spice. It MAKES THE SANDWICH!

How to Make The Vegetarian Reuben Sandwich
Grill it in a cast iron skillet or broil it in a toaster oven for ultimate easy. Meal prep the sauce and beets to make this sandwich in under 15 minutes!
Traci’s Tips
- Make it Gluten Free: Find your favorite gluten free bread and whip this up in no time! You may like my Gluten Free Sourdough Bread.
- Make a Vegan Reuben Sandwich: simply leave the Swiss cheese off and be sure to use vegan mayo. I like Follow Your Heart – Vegenaise.
- Meal Prep? Yes please! Make the sauce and roast the beets ahead. It takes about an hour to roast and peel beets; they can be done up to three days in advance. The sauce can last for weeks in the fridge.
Vegetarian Reuben Sandwich with Roasted Beets

- 2 1/2 teaspoons Ketchup
- 1 teaspoon Sriracha, add an extra 1/2 tsp for more spicy
- 1/2 teaspoon Dijon Mustard
- 1/2 teaspoon Vegan Worcestershire Sauce, I like Wizards or Annies

Instructions
For the Russian Dressing (sauce):
- In a small lidded container add the mayo, ketchup, Sriracha, dijon, Worcestershire, pepper and dill pickles. Whisk to evenly distribute the ingredients. Lid and store in the refrigerator for up to two weeks.
For the Sandwich:
- Make it in a skillet or broil the sammie in the oven (no oil required). A. In a Skillet: Lightly brush a cast iron skillet with olive oil. Place two pieces of bread in the pan and slather each side with the sauce. Over the sauce on each side of the bread, add a slice of Swiss cheese if using. Top one side with beet slices, pile them high if desired, then top the beets with sauerkraut.Turn the heat onto medium and lid the pan. Toast for 4-5 minutes until the cheese is melted and/or the beets are warm. Remove from heat and put the sandwich together. Share right away. ORB. In the Oven: Slather each side of bread with the sauce. On each side of the bread, add a slice of Swiss cheese if using. Top one side with beet slices, pile them high if desired, then top the beets with sauerkraut.Place both sides in the oven (I use a toaster oven) under the broiler and broil for 4-5 minutes OR until the cheese is melted and/or the sandwich is warmed through. Remove from oven and put the sandwich together. Share right away.

Very delicious! I will make this sandwich again.
Hooray! Thank you for your note, Kristin!
INSANELY DELICIOUS!!! I have been craving a reuben and stumbled on this recipe. This is WAY better than any reuben I have had in a restaurant.
Best news ever, Teresa! This is one of my most favorite sandwiches ever. Who knew beets could pull this off?! Thank you for your note!
So good! I thought I would be the only one eating it, but everyone loved the sandwich, and actually requested a repeat! My husband and son are kind of obsessed with getting enough protein, any suggestions of sides or add ons? This doesn’t seem to have that much protein – right? Thank you!
Yay! SO happy you and family are enjoying the sammie, Maggie. Thank you for your note. I’m not sure what could be added to the sandwich itself without changing the flavor profile. A side salad to suit dietary needs would be a tasty accompaniment!
Thanks, I think a quinoa salad should work! And of course the cheese on the sandwich adds protein!
Writing this while I’m eating it… this is the best sandwich I’ve ever eaten and all made from ingredients that I already had!
Best news ever, Alex! Thank you for your note and giving the sammie a go! It’s such a nice surprise!
This was delightful! Wonderful combo of flavors. I used a loaf of sourdough that I had made for the bread. I will definitely make again. Thank you!
Ooooh on homemade sourdough… the best! Thank you for your note, Donna. So excited!
Still one of my favorites!
SO excited! Thank you for your note, and five star rating! Day made :D!
I made this sandwich for my sister-in-law and myself. Neither of us are vegetarians, just trying to incorporate more vegetables for our health. This sandwich is a flavor bomb with the sauce and you will not miss the meat one bit. Delicious!!!
Hooray for more veggies and a tasty sandwich, Denise! Thank you for your note and giving the Reuben a go – day made!
