Description
Lion’s Mane ‘Crab’ Cakes – crispy, vegetarian cakes made from shredded lion’s mane mushrooms, panko, and Old Bay seasoning. Served with dill aioli.
Ingredients
- 1 pound (450 g) lion’s mane mushrooms, shredded
- 1 medium onion, finely diced
- 1 small red pepper, finely diced
- 1/4 cup (60 ml) olive oil, plus 2 tablespoons (30 ml) for cooking
- 3 eggs
- 1/2 cup (120 ml) Kewpie mayo
- 2 tablespoons (30 ml) Worcestershire sauce
- 2 tablespoons (30 ml) freshly squeezed lemon juice
- 1/2 cup (60 g) panko crumbs for filling
- 1 1/2 cups (180 g) panko crumbs for breading
- 2 stalks spring onion, chopped
- 1 tablespoon (15 g) Old Bay seasoning
- 1 tablespoon (15 g) fresh Italian parsley, roughly chopped
- 11/2 teaspoon (5 g) salt
- 1/21/2 teaspoon (2.5 g) pepper
- 1/4 cup (30 g) all-purpose flour
- 2 tablespoons (15 g) all-purpose flour
- 1 clove garlic, minced
- 11/2 teaspoon (5 g) freshly chopped dill
- 1/4 cup (60 ml) sour cream
- Lemon wedges, for garnish (optional)
Instructions
- Step 1: Prepare the Aioli: In a bowl, combine sour cream, minced garlic, freshly chopped dill, and some lemon juice or seasoning as desired. Stir all ingredients thoroughly to create a creamy sauce. Set aside to allow flavors to meld.

- Step 2: Sauté the Vegetables: Heat 1/4 cup (60 ml) olive oil in a skillet over medium-high heat. Add finely diced onion and red pepper. Cook, stirring occasionally, until vegetables are soft and fragrant.

- Step 3: Cook the Lion’s Mane Mushrooms: Add shredded lion’s mane mushrooms to the skillet with vegetables. Stir occasionally, cooking until the mushrooms turn golden and the moisture has evaporated. This ensures a flaky, crab-like texture and improves binding.

- Step 4: Cool and Combine: Transfer the cooked mixture to a bowl and let it cool completely to prevent scrambled eggs. Once cooled, whisk eggs separately until combined and add to the mushroom mixture. Stir in 1/2 cup (60 g) panko crumbs, spring onions, Old Bay seasoning, chopped parsley, Worcestershire sauce, lemon juice, salt, and pepper. Mix well to form a cohesive mixture.

- Step 5: Freeze for Structure: Shape the mixture into cakes, wrap tightly in plastic wrap to prevent freezer burn, and freeze. Freezing helps the cakes hold their shape during cooking. Chill time can vary from a few hours to overnight depending on firmness desired.

- Step 6: Create a Breading Station: Set up three shallow dishes—one with 1/4 cup (30 g) flour, one with 2 tablespoons (15 g) flour, and one with 1 1/2 cups (180 g) panko crumbs. Dredge each cake first in flour, then in beaten egg if reserved, and finally coat with panko crumbs for a crispy exterior.

- Step 7: Fry to Crispy Perfection: Heat 2 tablespoons (30 ml) olive oil in a skillet over medium heat. Cook the breaded cakes for about 3-4 minutes per side until deep golden brown and crispy. Flip halfway through cooking for even browning. If cakes brown too quickly, reduce heat. The internal temperature should reach 165 degrees F for food safety.

- Step 8: Serve with Aioli: Serve the cakes warm, drizzled with prepared aioli or with the sauce on the side. Garnish with lemon wedges if desired.

Ingredient Notes
- Mushrooms: Look for fresh, firm mushrooms without blemishes for the best flavor. I prefer shiitake or portobello as they have a meaty texture that mimics scallops well.
- Cooking oil: A neutral oil, like canola or avocado, works well to let the mushroom’s flavor shine. Avoid olive oil, as it can overpower the dish.
- Garlic: Fresh garlic adds depth to the dish. Use whole cloves and mince them instead of using pre-minced garlic; it tastes way better!
- Lemon juice: Freshly squeezed lemon juice brightens the whole dish. Use a fresh lemon to get the most flavor, unlike those bottled options!
- Parsley: Fresh parsley adds a pop of color and fresh taste. Look for vibrant green leaves, and give them a rough chop before adding to the dish.

Recipe Tips
- If the mushrooms don’t brown well, pat them dry with paper towels before tossing them with oil and salt.
- When the garlic starts to brown, remove it from the pan immediately to prevent bitterness; this usually takes about 1 minute of cooking time.
- If your sauce is too thin, simmer it longer, about 5 minutes, to help it thicken and coat the back of a spoon.
- For uneven cooking, slice the mushrooms into uniform 1-inch rounds to ensure they cook evenly throughout, allowing about 15 minutes for the whole process.
- If the dish lacks brightness, squeeze additional fresh lemon juice over the top just before serving for enhanced flavor.
Serving Suggestions
Serve mushroom scallops alongside sautéed spinach or roasted asparagus for a vibrant plate. A light lemon arugula salad fits nicely as well.
Use mushroom scallops to make a delicious pasta dish with gluten-free noodles or incorporate them into a savory risotto. Add to grilled vegetable skewers or scoops of creamy polenta for a filling meal.
Top with a drizzle of lemon garlic sauce or a sprinkle of fresh parsley for added flavor. A hint of balsamic glaze can also complement the dish beautifully.
Recipe variations
- You can use king oyster mushroom stems in place of bolete stems for mushroom scallops, slicing about 4 ounces into thick rounds to maintain texture and size.
- Add 1.5 tablespoons of cooking oil, a pinch of kosher salt, and 2 teaspoons of non-pareil capers to the mushrooms for a subtle briny flavor that complements the dish.
- Either fresh or dried wild boletes can be used to vary the flavor profile; rehydrate dried ones in warm water before cooking for best results.
- If making for more servings, double the mushrooms to 8 ounces and increase cooking oil to 3 tablespoons, adjusting all sauce ingredients proportionally; this pairs well with Pan Seared Scallops.
