Vegan Black Bean Burger with Avocado Herb Sauce

Vegan Black Bean Burger with Avocado Herb Sauce

Craving a burger but you don’t eat much meat?  When eating a mostly or completely vegetarian diet, sometimes it means being unable to eat some of your favorite foods.  For me, I really missed hamburgers.  I tried so many different brands of store-bought versions of vegetarian burgers and just never really enjoyed them.  The flavors just always seemed to be off or the texture was just really weird.  Until I stumbled upon the idea of making my own black bean burger.

For certain a veggie burger isn’t the same thing as eating a juicy, beef burger, but it can be a good substitute especially when it tastes great and meets my requirements for a great meatless burger.  I want my black bean burger to have a nice crispy or firm exterior as I know the inside will likely be a little mushier than a normal burger.  And the burger needs to be full of flavor.

Creating my vegan black bean burger

Beans or legumes are generally at the heart of a veggie burger as they help bind the ingredients together and also contribute moisture to the burger.  I chose to use black beans primarily because the burger also has southwestern flavors and I think that combination works well.

Cooking with mushrooms in vegetarian dishes works to add a meaty flavor because mushrooms have a natural earthiness and umami flavor.  Lastly, a good veggie burger needs a dry ingredient to absorb some of the moisture and to work with the beans to hold the burger together.  In this recipe, I use oats to provide that purpose.

I also wanted to boost the protein content which led me to add quinoa to the recipe. Quinoa is also great because it’s a complete protein and contains all the essential amino acids our body needs to function.

[bctt tweet=”In my opinion, this is the best vegan black bean burger recipe I’ve eaten.  It’s crispy on the outside and has plenty of flavor.” username=”Lyn_Croyle”] This burger is perfect to serve the traditional way in a bun and a side of sweet potato fries.  But it also works in a bowl served on top of a bed of rice and topped with a yummy sauce and some veggies and avocado.  I tried it both ways while testing the recipe!!

The recipe makes 6 burgers and the burgers freeze well.  So if you have any extras, just place them into a plastic bag with parchment paper in between the burgers.  Then when you want to prepare, simply remove the burger and heat in a 350 degree oven until heated through, likely 15-20 minutes.
