I love burgers…burgers are amazing. The vegan sweet potato lentil burger is one of THE BEST plant based burgers I’ve made. This may sound unusual, but before I went vegan, I wasn’t a huge fan of burgers. Vegan burgers are amazing because you can make so many different kinds and they are all so delicious and can even be super nutritious! This is one of those deliciously nutritious burgers and I am so excited to share it!

What makes it so good? Well for starters it is:

  • Oil Free
  • Gluten Free
  • Full of fiber, folate, protein, and other goodies
  • Easy to make
  • Hearty, tender, and full of flavor!

I think I’ve discovered the perfect base for a plant based veggie burger: 1 part oats, pulsed in blender + 1 part mashed vegetable (in this case, sweet potato) + 1 part beans or lentils. This combo makes the burgers tender, but not mushy. It’s perfect!

Now that we have a perfect burger texture, it’s time for the perfect burger seasonings. For this recipe, I use a combo of the spices shown above, with the addition of some nutritional yeast and vegan Worcestershire sauce to make a savory burger that is packed with flavor.

Because these burgers are oil-free, they may stick to the pan. So, make sure to use silicone mats or baking paper.

When I make these burgers, I make a lot. They keep in the fridge for about a week and I will put a bunch in the freezer for longer term storage too.

When it comes to burger toppings, I love lots of tomato, crunchy romaine, avocado, and lots of secret sauce. 

Pssst! Secret sauce is just 2 parts vegan mayo + 1 part ketchup + (optional) pickle relish. Now you know.

    I made these burgers today, they are the bomb. Thank you so much for showing me the Vegan life. I am finally enjoying what I eat.
    You’re very proud Momma

  2. seriously sounds easy, nutritional and delicious. will try very soon

  3. can you make ahead and freeze?

    • rootyfruityvegan

      Yes! I always make a bunch and freeze them. They can be reheated on a pan or microwaved for 30-45 seconds on each side

  4. Hi there! These burgers look unreal, I don’t have a tomato on hand, would it make much of a difference if I just left it out?

    Thanks in advance,
