Nutritional information may vary between brands and whether you are using canned or dried beans. Check the labels before purchasing.
Black soybeans are available in cans, ready for use or dried, which need soaking in water before use. We use the Eden Organic Black Soybeans but there are other brands to try.
HOW TO COOK BLACK SOYBEANS
As with any dried beans, they need to be soaked in water before use. Place the beans in a large bowl with water and salt. Cover and keep in the fridge for 12 hours (ideally overnight). Rinse the beans thoroughly. Then place then in a large saucepan and cover with water. Bring to the boil and simmer for 1 ½ to 2 hours until the beans are soft.
For a quicker method of cooking dried beans, cook them in a pressure cooker.
If you are using canned black soybeans, rinse the beans before use.
Your beans are now ready to use in a recipe. They make great low carb refried beans or keto chili.
We have kept the ingredients for this keto burger, vegan and not used any egg for binding.
HOW TO MAKE BLACK SOYBEAN BURGERS
The keto burger mixture is cooked in a skillet then processed in a food processor to combine the ingredients. Pulse the mixture for a chunkier bean burger.
Fry onion, garlic and spices and add black soybeans
Blend the mixture in a food processor
Form into patties
Pan fry or air fry burgers
These keto vegan burgers can be made ahead, stored in the fridge and cooked when you are ready to eat.
You can change the ingredients to make a tasty vegetarian burger to your liking.
- Walnuts - these can be omitted or replaced with almonds or peanuts. If you want a nut-free burger and a lower fat burger, use sunflower seeds instead.
- Red onion - chopped green onion can be used and does not need to be cooked before forming the burger.
- Red pepper - cooked mushrooms or baby spinach could replace the vegetable element of the burger. Try roasted red pepper too for extra flavor.
- Vegetarian - add Cheddar or Feta cheese to the burger.
- Spices - We use a blend of cumin, chili and smoked paprika but you can use herbs or other spices. Chopped jalapenos can add some extra heat.
- Ground Flaxseed - this can be swapped with other low carb flour such as coconut flour, almond flour or lupin flour. The quantities will need to be changed. Add a ¼ cup at time when processing the burger mixture until it starts to bind.
If you have leftover cooked burgers, store them in an air tight container in the fridge and they should last for 3-4 days. They reheat well either on the stove or in the air fryer.
To freeze, place a square of parchment paper between each patty to prevent sticking. Then store in an air tight container or zip lock bag. They will freeze up to 3 months.
Defrost the bean burgers thoroughly before use.
