Vegan Crab Cakes

  1. In a small bowl, combine the flaxseed meal and water. Mix thoroughly and set aside.

  2. Add the lion’s mane mushrooms to a large food processor. Pulse 2-3 times to roughly chop the mushrooms. You do want some sizeable pieces.

  3. Add the butter beans and pulse a few more times.

  4. Combine the vegan mayonnaise, Worcestershire sauce, fresh lemon juice, Djion mustard, Old Bay Seasoning, dulse flakes, salt and granulated garlic into a small bowl. Mix thoroughly.

  5. Add the mayonnaise mixture, red bell pepper, scallions and crushed oyster crackers to the mushroom mixture. Mix thoroughly.

  6. Refrigerate the mixture for 1 hour. This will make it easier to make the cakes.

  7. After the mixture has chilled, form the crab cakes with your hands.

  8. Preheat your air fryer for 3-5 minutes. While the air fryer is preheating, brush both sides of each crab cakes with a light layer of oil.

  9. Air fry the crab cakes for 6-8 minutes or until crispy. See Recipe Notes.

  10. Serve immediately with Remoulade Sauce, scallion greens, microgreens and lemon wedges.

Recipe Notes

  • I’m usually a fan with washing my mushrooms, but I opt to lightly remove any debris from lion’s mane mushrooms with a damp paper towel. I find that any water absorption results in a soggier end product.
  • If you find you don’t have Old Bay Seasoning, I made a suitable substitute with ingredients that I had on hand.


1 tsp salt

1 tbsp celery seeds

2 tsp Cajun seasoning

1 tsp dry mustard

½ tsp pumpkin pie spice (choose one that include cinnamon, nutmeg, ginger, allspice and cloves)

¼ tsp crushed red pepper

½ tsp white pepper

5 bay leaves


  • Combine all of the ingredients in a coffee grinder or mini food processor and pulse until no large pieces remain. This recipe makes 2-3 times the amount of Old Bay Seasoning that you’ll need for this vegan crab cakes recipe. Store the excess in an air-tight container for later use.
  • As I mention in my blog post, I have two air fryers at home and they cook differently. I recommend keeping an eye on your crab cakes to get the right crispy exterior. If you opt to use a convection oven, set the temperate at 400º and bake for 8-10 minutes, checking the crab cakes frequently.
