A tasty spin on regular black bean burgers. This version is made with sweet potatoes, oats and flax so they’re gluten-free and vegan. They’re loaded with flavor and hold together well!


  • 1/2 cup chopped onion
  • 2 cloves garlic
  • 1/4 cup fresh basil
  • 15 ounce can of black beans, rinsed and drained
  • 1/2 sweet potato, chopped into 1/2 inch pieces and boiled for 78 minutes until soft
  • 1/2 cup gluten-free rolled oats
  • 2 1/2 Tablespoons ground flax mixed with 3 Tablespoons water (or 1 egg)
  • 1/2 teaspoon chili powder
  • 1/2 teaspoon cumin
  • sriracha sauce, to taste
  • sea salt, to taste
  • whole grain burger buns


  1. Heat a skillet with non-stick spray. Once warm add the onion and garlic in to the skillet and cook until they are limp and start to brown a bit. Put the cooked onion mixture into a food processor (affiliate link) or blender. Add the basil and pulse several times. Add the beans, sweet potato chunks and oats to the processor and pulse five or six times. Don’t over process, as you want your bean burgers to be a little chunky. The beans should be broken up but there should still be some small chunks.
  2. Transfer the veggie and bean mixture into large bowl and stir in the flax egg, chili powder, cumin, sriracha and salt. Form into five patties. (If the mixture is too wet to work with at this point add extra oats).
  3. In the same skillet, heat on medium, spray non-stick spray and add the patties, cook each side until browned, about 6-7 minutes total OR you can bake them on 375° for about 25 minutes, flipping once.
  4. Put the burgers on a bun and serve with condiments of your choice. I used spicy mustard, onions, lettuce, and ketchup.

    • Yay! I’m so glad you enjoyed these black bean sweet potato burgers and I’m glad they turned out for you without the oats. Thanks so much for taking the time to leave a comment and star rating. I so appreciate it!

    • Hey Jessica – I have tons of recipes on the website, is there a specific recipe you’re looking for? I’m so glad to hear that you and your mother have enjoyed this burger recipe. Thanks so much for coming back to comment and star rating, I so appreciate it!

  1. Wow – these are the best veggie burgers ever! Even my non veggie burger loving husband said they were great and would have them again. Thanks for the awesome recipe!

  2. Made these last night, they were amazing! Has anyone tried freezing them? I would love to keep some on hand for quick meals!

  3. Absolutely great! I didn’t use the food processor in steps, just threw everything in and turned it on low until everything was combined. Honestly a little sticky doesn’t make much of a difference. I added about 1tbs of whole wheat flour to the initial recipe (could have added oats but didn’t want to blend it too much more). With a bit of olive oil in a non-stick pan, I was able to form 5 balls and drop them directly onto the pan, which caused them to flatten out a bit, and they cooked beautifully! No need to add anything extra. Thanks for a great Sunday dinner! Served with thick sweet potato wedges and salsa 🙂

  4. This recipe is driving me crazy. I haven’t tried it yet, but I’ve had to add over three cups of oats so far and its still very sticky. I”m having to add more spices to keep it from being bland from the oats

    • I’m so sorry you’re having trouble, Hannah. You definitely shouldn’t need 3 cups of oats. Was your sweet potato extra large? I’m wondering if that is making the mixture extra moist?

  5. The black bean/sweet potato burgers were phenomenal!! I used half of this recipe, half of your other ones (added in the egg again) and re-glutenized it by adding about 1/4 cup whole wheat flour instead of adding too many more breadcrumbs. We also added a bit of garam masala (1 teaspoon or so?) to the burgers to Indianify them a bit.

    Out of six, I only had one, because the boyfriend ate the other five. Next time – doubling the recipe! Or hiding some burgers. Not sure which.

  6. The black bean and sweet potato burgers were absolutely delicious! I did, however, add another ingredient, which were called Chunky Chickpeas from the brand called Tastybite. The chickpeas are already seasoned, which added a unique and tasty flavor to the burger. I will definitely be making these very often this summer!

  7. so good to see your beautiful face today, girl.

    thank you so much for listening so patiently. you are a sweetheart, for sure! really enjoyed our lunch – can’t wait to hang again soon. maybe when isaac settles back in we can have a house-warming date 🙂

    ps – i think the best GF cereal is enjoy life’s nutty flax. like rice krispies, but WAY more nutritious. and crunchier too!

  8. That was so sweet of you to cook for your Dad!

    What a wonderful idea for WF to have that garden! I hope they can do something like that when they are done building our store. 🙂

  9. that would be such a crazy burger combo.. black beans and sweet potatoes!! wow. i’ll probably be making lots of veggie burgers this summer so these will be added to my list. THANK YOU!! <3

    barbara's products.. and especially those rice puffs are really tasty! i like how they are pretty filling too and the taste is awesome! not like kashi which i didnt really like. the other varieties seem to work better in baking it seems.

    xoxo <3

  10. The Village Garden looks so cute, and I had no idea that’s what buckwheat looked like! Never thought about it, but definitely not what I was expecting!

    How does nayonaise compare to the real thing? It it good or just taste like another soy replacement for something with eggs?
