Don't come for me, but I am not a fan of meat substitute burgers. I believe that one of the great benefits of a plant based diet is eating whole foods like veggies and beans. Impossible and beyond burgers are okay sometimes, but nothing beats a homemade veggie burger. These Vegan Oyster Mushroom Burger with Black Beans are such a good veggie burger recipe.

These burgers are meaty without any meat thanks to the oyster mushrooms. They are also packed with protein thanks to black beans. I snuck in some oats to this burger to round out the protein and make them a complete protein source.
Let's get into the recipe.

Instructions for making Oyster Mushroom Veggie Burgers with Black Beans
- Preheat oven to 425 degrees.
- Add beans, onion and mushrooms to a sheet pan lined with parchment paper. Lightly coat beans in salt and pepper. Toss oyster mushrooms with 1 tablespoon soy sauce and a splash of oil. Bake for 15 minutes. Leave the oven on once this time has passed because we will be cooking the burgers again.
- While beans, onions and mushrooms are cooking, make your flax egg. Mix together flax and water and let sit refrigerated for 10-15 minutes.
- Once beans, onions and oyster mushrooms are done cooking transfer them to a food processor or blender. Add flax egg and the rest of the ingredients to the blender. Pulse a few times until partially blended, you still want some texture but you want the mixture binded.
- Form 3-4 evenly sized burgers on a sheet pan lined with parchment paper, I made 3 with handfuls of the mixture. Bake for 20-30 minutes or until burgers have started to brown. For best cooking results flip halfway through (optional)
- Let burgers cool and serve with your favorite sides and toppings. I recommend a toasted bun with avocado, ketchup and mustard
Substitutions
- Oyster mushrooms- can be subbed with another mushroom like shiitake or baby bella
Equipment
I used my Cuisinart Food Processor for this recipe.
