(This is a summary with step by step photos, full recipe measurements and instructions are in the recipe card below.)

Gather your ingredients, you’ll only need 10.

Ingredients needed to make vegan sweet potato burgers on white deck.

Begin by cubing your sweet potatoes and put them in a pot of water to boil.

Meanwhile, dice your onion, pepper and mushrooms. Then add them to a pan and dry sauté until soft and reduced, approx. 5 minutes. Set aside. (photos 1-3)

Add the cooked sweet potato, white beans and the seasoning to your food processor and process until broken down and combined. (photos 4-5)

Then, add the sautéed veggies and oats to your processor and pulse a few times, just to mix them through. (photos 6-7)

NOTE: If you have a small food processor, work in batches, as needed, and DO NOT over process or puree. You want a chunky texture.

How long do they keep?

Your vegan sweet potato burgers will keep refrigerated, in a sealed container for 3-4 days.

Or, you may freeze them in a freezer safe, air tight container for up to 3 months. Make sure they are cooled to room temperature before freezing, and divide any layers with parchment paper to prevent sticking.

How to top these burgers

Up the spice level by adding some pickled jalapenos and sriracha mayo. Or tone it down by topping your burgers with some creamy guacamole.

Or keep it classic with lettuce, tomato, pickles and onion.

What to serve with them

These burgers pair particularly well with potato wedges, French fries, sweet potato fries or plantain chips.

If you’re eating light, skip the bun and use these patties to top a fresh green salad.

Can I make any substitutions?

For gluten free, just make sure to grab certified gluten free oats and your favourite gluten free buns, if using.

If you don’t have white beans on hand, you may sub for a can of chickpeas instead, with similar results.

Feel free to omit or substitute any of the spices that you’re not fond of. Or adjust according to your taste.

Expert Tips & Notes for Success

Do not over process. You want a nice textured burger here, so make sure not to over do it in the food processor.
Work in batches if you have a small processor. Don’t try and jam everything into a smaller appliance or the bottom will get pureed, and the top will stay chunky. This won’t give you the best texture.
Use wet hands to make your patties! The batter will be a little sticky, so using wet hands will prevent the patties from sticking to your hands.
Taste the batter and adjust the seasoning if needed. Once your batter is processed, taste a sample and add more salt, pepper, garlic powder, cumin or cayenne, if needed. Always season to your taste.
Make it smoky. If you want add a smoky flavour to your burgers, add a ½ teaspoon of smoked paprika to the batter.
