Flavor and texture rich, simple ingredients shine in this easy vegetarian sandwich recipe. Simple to pull together, this Roasted Beet and Sauerkraut Sandwich includes a good schmear of whole grain mustard bringing all the flavors together. This recipe is vegetarian and vegan.
Getting to this Sandwich
Before we get to this sauerkraut sandwich recipe, a note on how I got here. Being a foodblogger has afforded opportunities to explore and dive into food on a whole new level. Becoming familiar with new-to-me ingredients and ways of cooking has broadened my palate and enlightened my world view on food.
Recipe development and food photography is my work, now, so exposure to all things food is on the daily agenda.
For recipe inspiration, I thumb through the pages of magazines, cookbooks, the Vegetarian Flavor Bible, and scroll through Pinterest and Instagram. But most of the time, I gain inspiration from the food that the farm stands are offering and whatever is in season. I’m frequently asking, how can I use this ingredient in a recipe.
Beets have been on the agenda lately, so Rob and I have been pickling all the beets. But last week I decided I’d roast the latest bunch for salads or snacks…
But then I spied some sauerkraut… and had just made a new loaf of sourdough (I’ve been investigating multigrain). I had everything I needed to make an easy beet and sauerkraut sandwich recipe!
And so it happened.
Now, I would have never thought to put beets on a vegetable sandwich. Really. And I use to despise sauerkraut. But my taste buds have matured… as has my appreciation for fermented foods.
Quick Guide: How to Make Roasted Beet and Sauerkraut Sandwich
You just need a few simple ingredients to pull this mouthwatering easy vegetarian sandwich recipe together!
- Bread – I love sourdough, but whatever your favorite bread is, is the best bread!
- Roasted and peeled beets – I have a tutorial on How to Roast Beets if you need.
- Whole grain mustard
This vegetable sandwich is simple to pull together after the beets are roasted. I usually roast a batch on the weekend and eat on them throughout the week.
This veg sandwich is texture rich, sweet, spicy and sour mouth party. Woah! It’s all in there.
And the best part, this beet and sauerkraut sandwich comes together with four basic ingredients. Now that’s what I call easy peasy!
A Few Recipe Notes
- Beets can be roasted up to four days in advance and stored in the refrigerator. Keeping these on hand means I can pull a quick salad together or make a fabulous veg sandwich!
- Although I love homemade sauerkraut, it’s generally an ingredient I purchase. Pickled Planet is my favorite brand.
- Don’t skimp on the mustard! Whole grain mustard gives this sandwich a tangy and full bodied flavor that you’ll return to again and again. I like Maille.

Roasted Beet and Sauerkraut Sandwich
- 3 Roasted and Peeled Beets medium in size (roasting instructions below)
- Bread sourdough, seedy, homemade... use what you love!
- Prepared Whole Grain Mustard the spicier, the better!
- 1 C (225g) Sauerkraut prepared or homemade, drained if needed
- Sprouts, Microgreens or Lettuce optional
To Roast the Beets:
- Preheat oven to 400F (204C). Trim the greens to the base of the beets and save for another recipe (I love them in green smoothies!). You won't need the greens here. Trim the tail and discard. Place beets in an oven proof baker or pot with a lid and fill with 1/2" - 1" water, cover and roast for 40-50 minutes or until fork- tender (the larger the beets, the longer the roast). Once the beets are out of the oven, allow to cool until they can be handled. There are two ways to approach beet peeling. Use a vegetable peeler and gently remove the skin or simply slip the skins off. Your choice. Once the skins are removed, slice the beets into thin (about 1/4") discs. Refrigerate for up to three days.
To Assemble the Sandwich:
- Slather two slices of bread with a generous schmear of mustard. Arrange a layer of beets, overlapping a bit, then top with a few heaped tablespoons of sauerkraut. Sprinkle the top with sprouts, microgreens or lettuce. Enjoy right away.
This was easy, different, and so delicious. There are not many vegan lunch options where we live in West Texas and the ones that exist are a result of removing about 5 items from an existing menu item (yes 99.9% of all menu items here have either meat or dairy by default). We have been in a rut of hummus and sliced garden veggie sandwiches and chickpea salad for a while. This was quick to throw together and so refreshing from the norm. We had it with your fennel and white bean soup, which was also delicious.
I’m always looking for vegetarian ways to eat sauerkraut and this was delicious! Bought roasted beets and toasted the breD. Had a sandwich 5 min after I got home from the store. Thank you!!
Love reading your note Sarah! Who knew? I love this combination of flavors too!
Something this easy to make shouldn’t be so delicious! I’m definitely stocking my fridge with these ingredients so I can make this on the fly now, such a tasty lunch treat! Thanks for sharing :)
Hey Sam! Thank you for coming back and leaving a note. So simple, right? So happy you enjoyed it!
I’ve been drooling over this ever since it was posted. Do you serve the sandwich alongside anything, or do you find it satisfying enough on its own?
Hi Claudia… thank you for your note! I find it satisfying on its own, of course with a side of Kettle chips, or carrots and hummus ;) . I hope you enjoy it!
Thank you so much, Traci, for your lightning fast response. I followed your advice, and served it up with a side of Kettle chips, and oh my gosh, this was THE most perfect sandwich I have ever eaten. I don’t think anything will ever be able to compare in that department. This recipe is dynamite.
You got it, Claudia! Thank you for your note. Can you believe how satisfying it is? Now, if you like this one, have you tried my Smashed Chickpea Sandwich? So happy you enjoyed it with those Kettle chips :o !!

Seasonal produce is indeed the best inspiration of all. I often struggle to find ways to cook with beets and I love the idea to add them to a sandwich. Plus you can’t go wrong with sourdough and sauerkraut. So much deliciousness going on in this sandwich! And I love the color choices too. Gorgeous work, Traci!
I’m with you, Sarah. I tend to only enjoy beets by roasting or pickling them and putting them on salads or just eating them out of the jar. But here’s another way to love beets! Hooray!
When I think of “vegan,” I don’t usually think sandwiches, but I will now! This was so tasty – beets in a sandwich, who would have thought? Thanks for the recipe.
I’m with you! Who would have thought? LOL – thank you for your note VK! So happy you gave it a go!
Traci, you are amazing!!! What a fabulous looking sandwich with home made sourdough. Absolutely love all the colors and the beet, my favorite.
Loving it my friend.
I love using sauerkraut in sandwiches – usually my go-to is the Reuben but this looks absolutely delicious! Thank you so much for sharing, I can’t wait to make this for my family!
Oh wow – I’d never thought about it as a reuben… ! But I can see… now I just need to whip up some thousand isl. dressing (!!) I hope you and your family enjoy it. Thank you for your note, Billy!
This sandwich looks incredible! I love beets in sandwich, they add a lovely flavor and texture to the sandwich! I love that you made your own homemade sourdough bread to go in this gorg sandwich :)
Thank you love…. I simply love homemade bread! And beets on a sandwich? Who knew?
Geraldine | Green Valley Kitchen
I LOVE beets, Traci – and never thought of putting them into a sandwich – this is brilliant! Ferment foods are very in right now – so sauerkraut makes a tasty addition to this sandwich. And yes to grainy mustard! Love this – pinning now to share!
Right? I’m with you, Geraldine! I mean, sometimes things just come to us and we gotta try them! Thank you for your pin! xo
Alexandra | Occasionally Eggs
Look at that mustard!! I’m a total mustard fiend and you’re combining all my northern-friendly favourites here, Traci! Sounds to die for <3
Although I looove a good mayo on a sandwich, there are some that beg to be slathered in mustard. And I’m SO with you. Potatoes roasted in mustard? Yes please! In dressings, stews, mac and cheese! YES PLEASE! I need to write a recipe book on nothing but mustard! LOL. I hope you enjoy it love.. xo
This has been my favorite kind of sandwich forever (we call them beet rubens) – glad to see others enjoy it as well! It is such a fantastic combination. Also, if you have access to a smoker and you smoke the beets, it brings in a whole new level of flavor.
Oh my goodness, who knew? Beet rubens! I just got a little smoker box for the grill last summer. I’ll have to put a few beets on next time I use it! Thank you for your tip, Kate!
Karen @ Seasonal Cravings
This is so creative. I would never have thought to put all these goodies together. I’m a huge fan of beets but don’t make them a lot bc they are so messy. This sandwich makes it all worth it!
Thank you Karen! Indeed messy, but worth that mess! I don’t mind it and tend to batch cook them so I get messy once and then the work is done!
Laura | Tutti Dolci
What an incredible sandwich, this needs to be on the menu for this weekend!
Hey Laura! Thank you my dear! DO IT!
Traci! Look at all these colors! One bite and you are literally eating the rainbow. Sauerkraut and beets are such a great combo, and that wholegrain mustard and homemade sourdough too. Absolutely love. And it’s so good to know that you think about food all of the time because I do too. :)
Ohhh yes! The rainbow! LOL – thinking about food all day. LOL – that sounds funny… and although there are so many things on my mind all the time, I’ve gotta say, food is never far from the forefront! xo
So funny, I had your chickpea dill pickle sandwich beside me last night as I was making my grocery list for the weekend (if I were a more organized soul, I’d shop once a week? is that what normal people do ;o anyway that’s not me). I like how you’ve combined the roasted beet with sauerkraut – it sounds so tasty yet uncomplicated. I’ve yet to find a brand of sauerkraut that I like tho (I’ve tried a few from whole foods) any recos? Love the contrasting colors in your beautiful beets and the turquoise background Traci, so pretty!
Hooray for that smash up, Kelly! I love it too.. and it’s just so darn easy! Once a week shopping is the only way I shop simply because I live so far away from a well stocked grocery. If one were closer, I’m certain I’d go more frequently. An uncomplicated sandwich indeed… similar to that smash up :D . As far as sauerkraut, I like Pickled Planet – :D ! I hope you enjoy this one too! xo
Thaank you Sabrina!
Mary Ann | The Beach House Kitchen
Wow! What a sandwich Traci. I have always loved sauerkraut. I’m late to the beet train though, but I’ve been working on it. I love being able to create recipes and put things together most people wouldn’t think of, but would enjoy. Thanks for sharing this delicious combo. Your photos are leaving me so hungry. They’re just gorgeous! Happy weekend to you and Rob.
Hehe! Well said, Mary Ann… I find beets to be so enjoyable. Most of the time I eat them straight from the fridge after roasting or pickling. They’re just fabulous!
Liz @ Floating Kitchen
This looks fabulous, Traci! I actually puts beets in grilled cheese sandwiches (with goat cheese) and I love it. Never tried with sauerkraut. I need to do that next! Isn’t it so fun to play with new combos?!?! Glad we get to do this as a job. Lol. Enjoy your weekend!
Omgeeee!!! Goat cheese!? I’m thinking now I remember that sandwich! 🤤 No doubt… a lot of work, but yes what fun!!
