- 1 cup walnuts
- 1 cup mushrooms
- ½ white onion coarsely chopped
- 4 cloves of garlic
- ¼ tsp smoked paprika
- ¼ tsp garlic powder
- ¼ tsp onion powder
- ¼ tsp salt
- ¼ tsp pepper
- 1 tsp soy sauce

- ¼ tsp liquid smoke
Sauteed mushrooms and onions
- ½ white onion sliced thin
- 1 cup mushrooms
- 1 tbsp vegan butter or oil
- Salt and pepper to taste
Toppings
- vegan cheese
- lettuce
- tomatoes
- avocados
- vegan mayo
Instructions
- Make the flax egg by combining the flax meal and water, set aside.
- Process the oat in the food processor to make oat flour, set aside.
- Combine the walnuts, mushrooms, onions, and garlic in the food processor and pulse until coarsely chopped.
- Heat a non-stick pan over medium heat. Add the mushroom mixture to the pan and cook until most of the water has evaporated and the mixture is browned, about 4 minutes.
- Put the mixture in a mixing bowl and let cool for a couple of minutes.
- Combine the the walnut mixture, the oat flour and the flax egg together. Fold in the spices, Worcestershire sauce, and liquid smoke. Place this in the fridge to chill for 1 hour.
- While the walnut mixture is chilling, sauté the mushrooms and onions for the toppings. Add the vegan butter to a non-stick pan over medium heat, add the mushrooms and onions, a pinch of salt and some pepper. Saute for about 10 minutes or until the onions are caramelized and starting to burn slightly.
- You can also prep the other toppings and clean the work area while the mixture is chilling.
- Once the mixture is chilled, divide it into four equal parts, and roll them into balls.
- Heat a non-stick pan over medium heat, add a small amount of oil and one or two of the balls. Cover it with a piece of parchment paper and press it flat with a spatula (see the pictures above if you need a visual). Remove the parchment paper and cook for about 2 minutes and flip.
- Add a piece of the vegan cheese to the top and cook for about 30 seconds. Then add a tbsp of water to the side of the pan, away from the burgers, and immediately cover the pan to trap the seam and help the cheese melt. Keep covered for 1 - 2 minutes and then remove from heat.
- Assemble 2 (1 is okay too) of the smash burger patties on hamburger buns with lettuce, tomatoes, vegan mayo, avocado and the sauteed onions and mushrooms.
