Mexican Black Bean Buckwheat Burger

This Mexican Black Bean Buckwheat Burger is full of nutrient-rich, gluten-free whole food ingredients and is one of those recipes that you can make in advance, freeze and then cook as you need them. These burgers make delicious sandwiches and they are also yum wrapped in steamed collards with Ancho Chipotle Sauce, sprouts and greens. They are also delish cooked and crumbled into salads. Make a batch and eat right away and freeze the rest so you have a healthy quick meal on those nights that you are too tired to cook anything from scratch.


Makes: 8-10 burgers

Food processor
Chef’s knife
Silicone spatula
Large pan (maybe)
Unbleached parchment paper (maybe)
Cookie sheet (maybe)

Try to buy everything organic. Here’s why.
1 red or yellow bell pepper, ribs and seeds removed, diced
1 red onion, diced (here’s a tip)
1 large carrot, diced
4-5 cloves garlic, minced
Cold-pressed, virgin coconut oil
1/4 sunflower seeds, soaked
1 tbsp chia seed
2 dry chipotle peppers, remove seeds (unless you are a masochist and like breathing fire—like me sometimes)
2 tsp apple cider vinegar
2 tbsp fresh lime juice
1 tsp lime zest
1/4 cup +2 tbsp pure water
1 tbsp nutritional yeast
1 3/4 tsp fine ground sea salt
1/4 tsp fresh ground pepper
3/4 tsp ground cumin
1 1/4 tsp ground coriander
1 cup packed chopped purple kale (any kind is fine)
2 cups soaked and cooked black beans—a little over 1 cup of dry (here’s how and why I recommend soaking)
1 cup hulled buckwheat groats, soaked and cooked—a little over 1 cup of dry (here’s how and why I recommend soaking)
1/2 cup cilantro leaves
Gluten-free flour of your choice (GF all-purpose, garbanzo, garbanzo/fava and almond flour work well)

Optional & Recommended Additions:
Creamy Ancho Chipotle Sauce
Gluten-free or sprouted slider buns for burgers
Steamed collard greens for a wrap
Mixed greens for a salad
Fresh sprouts
Fresh greens


Let’s get started.
In a large pan, warmed over medium heat with 1/2 tsp cold-pressed virgin coconut oil, brown red pepper, onion and carrot. Add garlic and cook 3 more minutes then remove from heat.

Toss sunflower seeds, chia, chipotle peppers, apple cider vinegar, lime juice, zest, water, nutritional yeast, salt, pepper, cumin and coriander into the blender and mix until thoroughly creamy.

Place kale, one cup of black beans, 3/4 cup buckwheat and cilantro leaves into food processor. Add cooked veggies and pulse about 5 times—break it up a bit.

Add creamy sauce from blender and pulse 20 times so mixture looks like below. You don’t want paste so don’t over pulse. You want beautiful colors chopped together enough that they bind, but not too much that you lose texture.

In a large glass bowl, take the remaining cup of beans and mash a bit with a fork. Then fold in processed mixture with 1/4 cup remaining buckwheat.

If you are going to cook your burgers immediately, there are two ways. You can cook them with a little coconut oil in a frying pan, or you can bake them. I prefer baking for two reasons. One, it’s less oil. Two, they actually hold together and firm up quite well post-baking. Either way, though, both methods are delicious. You choose.

Place the gluten-free flour of your choice on a large glass plate and drop a big spoonful onto flour. Sprinkle some flour around and on top of mixture to “powder” it enough that you can pick it up.

Form it into a “cake” with your palms. If at any time it seems too sticky, add more flour to the sticky spot. You may have to wash hands a few times if burger mix starts to cake too much or gather in your palm.

For pan frying, just add 1/2 tsp coconut oil to pan and cook your burger over low-medium heat for 7-10 mins on each side. Let one side really brown and cook before you flip. Be patient. We aren’t working with grease or eggs here, so in order to bind, you need to let the ingredients cook together.

For baking, set oven to 300°F and cook them for 35-40 mins on a parchment-lined cookie sheet.

If you want to freeze some for later…

just loosely wrap a burger in parchment …

…and then either individually wrap in foil or just place parchment-rolled burgers carefully (they are delicate until cooked so if they lose shape in the freezer, just reshape with a spatula as you cook).

This is what pan-cooked burgers look like.

And these are baked ones.

Both are something that you’ll end up adding to the recipe rotation. They are delicious.

You can freeze any cooked leftovers and you can refrigerate them in an airtight glass container.

  1. I am so excited to try these! It says it makes 8-10 burgers. Are these decent size? I want to make a bunch in advance. These will become a new staple—especially post-baby. You are a lifesaver! 🙂

    • Thanks Rea! They make about 4″ burgers…not big like a beef burger, smaller and more nutrient-dense 😉

    Finally got to try these and my family and I love them! I saved a little out to for taco filling. Yum!!
    (had to make a couple of substitutions due to lack of ingred.: quinoa flakes instead of buckwheat and lemon instead of lime. Still tasted great! Thanks!!

    Dear Heather,

    Thank you so much for creating this incredible, stunning, thorough website. I’m in love with it. I check it often and find it just delightful to the eye.

    I haven’t ever had any intention of going vegan, but this idea of plant based that you focus on, I can get on board with. I have recently wanted to start eating more vegetables and your site seemed like the perfect place to start. In February, I made your Creamy Kale with Millet, and it was so delicious I kept coming back to your site.

    Over the 4th of July, I made your Black Bean Buckwheat Burger with Ancho Chili Chipotle Sauce with Sprouts and Steamed Collard Greens. Yum. Yum. My uncle even opted for one instead of a burger! Woah! I was so impressed. I was even more impressed when even after one meal I felt a difference. I felt light and my throat, which usually feels as if it is on the verge of becoming sore, felt better! I am really excited to continue down the path of a plant based lifestyle. Thank you for the wonderful resources you have created. I haven’t found anything that can rival your research, aesthetics, and passion that is all summed up on this site.

    I can’t thank you enough,
