Ingredients

Scale
  • 12 ounces fresh lion’s mane mushrooms, cleaned and shredded or chopped
  • 3/4 cup panko breadcrumbs (90 g), or gluten-free breadcrumbs
  • 1 large egg, room temperature
  • 1/4 cup mayonnaise (60 ml)
  • 1 tablespoon Dijon mustard
  • 1 teaspoon Old Bay seasoning
  • 2 tablespoons fresh parsley, finely chopped
  • 2 tablespoons green onion, thinly sliced
  • 1/2 teaspoon garlic powder
  • Salt and pepper to taste
  • 34 tablespoons olive oil or vegetable oil for frying
  • For the lemon aioli:
  • 1/3 cup mayonnaise (80 ml)
  • 1 tablespoon fresh lemon juice
  • 1 small garlic clove, finely minced
  • Salt and pepper to taste
  • Optional: a pinch of smoked paprika

Instructions

  1. Prepare the Lion’s Mane Mushrooms: Gently clean about 12 ounces (340 g) of fresh lion’s mane mushrooms. Tear or shred them into chunky pieces resembling crab meat texture (about 5 minutes).
  2. Cook the Mushrooms: Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the shredded mushrooms and sauté for 4-5 minutes until softened and moisture is released. Remove from heat and let cool slightly.
  3. Mix the Crab Cake Base: In a large bowl, combine the cooled mushrooms, 3/4 cup panko breadcrumbs, 1 large egg, 1/4 cup mayonnaise, 1 tablespoon Dijon mustard, 1 teaspoon Old Bay seasoning, 2 tablespoons chopped parsley, 2 tablespoons sliced green onions, 1/2 teaspoon garlic powder, and salt and pepper to taste. Stir gently until evenly incorporated. Add more breadcrumbs if mixture is too wet.
  4. Form the Cakes: Shape the mixture into 6 equal patties, about 3 inches wide and 3/4 inch thick. Place on a plate or tray and refrigerate for 15 minutes to firm up.
  5. Make the Lemon Aioli: Whisk together 1/3 cup mayonnaise, 1 tablespoon fresh lemon juice, 1 minced garlic clove, and a pinch of salt and pepper in a small bowl. Add smoked paprika if desired. Cover and refrigerate.
  6. Fry the Crab Cakes: Heat 3-4 tablespoons oil in a large skillet over medium heat. Fry the patties for 3-4 minutes per side until golden brown and crispy. Use a spatula to flip gently. Drain on paper towels.
  7. Serve: Plate the crab cakes with lemon aioli on the side or drizzled on top. Garnish with extra parsley or lemon wedges if desired.

Notes

Chilling the formed cakes before frying helps keep them intact. Use medium heat to avoid burning the crust. Sautéing mushrooms first reduces moisture and intensifies flavor. Fresh lemon juice is essential for bright aioli flavor. For gluten-free, substitute panko with gluten-free breadcrumbs or almond flour. Vegan adaptation uses vegan mayo and flax egg.
