A Vegetarian Reuben Sandwich Obsession
I’m completely smitten with this sauerkraut sandwich. I mean, shall I say, obsessed?
When I was a kid, I’d do anything to avoid my sauerkraut loving parents at dinner time when I smelled it simmering on the stove. The aromas wafting from the kitchen would literally knock me out! It’s funny how our tastebuds mature overtime. Once repulsed by the humble fermented cabbage, now I seek it out, looking for new ways to enjoy it. Sauerkraut is absolutely fabulous and best of all, it’s loaded with good for us probiotics!
This sandwich is a riff on my original Beet Sauerkraut Sandwich. But I didn’t discover just how different that recipe tastes from this new rendition until a pit stop half way down Whidbey Island at a historic store called The Greenbank Pantry (aka, The Greenbank Store). A few years ago this store came under new ownership. As a new offering, they make fresh bread daily and whip up creative sandwiches including thoughtful vegetarian and vegan sammies (!!).
It was at The Greenbank Pantry where I discovered the holy grail of a Vegetarian Reuben Sandwich on a cold rainy day on my way down to the Bayview Farmers Market. It’s like remembering your first kiss, or first car. This sauerkraut sandwich is everything I want it to be! Full of flavor, slightly sweet, tangy, packed with crunchy yet tender veggies and a sauce that sent me over the moon! A triumph.
I called the store after devouring that sandwich and spoke with Alex, the owner and creator of the beet sandwich who shared the ingredients of his sauce with me. I wrote the ingredients down then got to work on creating the ratios for this recipe.
The sauce, Alex told me, is 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. Here’s what you’ll need:
- Dijon Mustard
- Mayo – for a Vegan Russian Dressing use vegan mayo – I like Follow Your Heart
- Black Pepper
- Dill Pickles
- Worcestershire Sauce – vegetarian and vegan
Ingredients for a Vegetarian Reuben Sandwich
With just a few simple ingredients, veggie reuben nirvana is right here. Here’s what you’ll need to whip em’ up:
- Really good bread. Go for a sturdy sourdough Rye or a seedy sourdough.
- Roasted Beets, sliced thin. I have a super simple beet roasting method if needed.
- Sauerkraut. I like Pickled Planet or Bubbies
- Swiss Cheese
How to Make a Vegetarian Reuben Sandwich
Meal prep the sauce and beets to make this sandwich in under 15 minutes! Grill it in a cast iron skillet or broil it in a toaster oven. Either way, enjoy this veggie reuben toasty warm with or without the Swiss. Here’s how to make em’:
- First, brush the skillet with olive oil. Lay both pieces of bread in the skillet and schmear both sides with sauce.
- Second, lay a slice of cheese on each side of the bread, over the sauce.
- Third, top one side with sliced beets. Stack em’ high or keep em’ low.
- Next, top with drained kraut.
- Last, turn the heat on and toast with the lid on for 4-5 minutes or until the cheese is melted.
Share toasty warm with a side salad or simple soup.
A Few Recipe Notes
- Make it Gluten Free: Find your favorite gluten free bread and whip this up in no time!
- 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, but they can be done up to three days in advance. The sauce can last for weeks in the fridge.
