King oyster mushrooms steamed and shredded into tender pieces make a convincing lobster roll filling. They’re dressed with mayonnaise, lemon, Old Bay, paprika, celery and chives and piled into toasted brioche or challah rolls.
Why King Oyster Mushrooms Work
The thick stems have a dense, meaty texture. Steam them until tender, then shred them with a fork while still warm; they pull apart into chunky, lobster-like pieces. Let them cool, then fold in the dressing. The filling can be made 2 days ahead; bring it to room temperature before serving.
Kosher Notes
Lobster isn’t kosher, which is why this roll uses mushrooms. Toasting the rolls in butter makes the meal dairy; use pareve margarine or olive oil to keep it pareve. Rolls aren’t suitable for Passover, but the mushroom salad can be served in lettuce cups during the holiday with kosher-for-Passover mayonnaise.
Variations
Torn hearts of palm work if you can’t find king oyster mushrooms, though the texture is softer.

Method
- Cut the king oyster mushroom stems into 3-inch pieces. Set up a steamer basket in a large pot with about 1 inch of water. Bring water to a boil.
- Steam the mushroom pieces for 10-12 minutes until they're tender when pierced with a fork. Remove from steamer and let cool for 5 minutes.
- Using a fork, shred the warm mushroom pieces by pulling along the grain. The mushrooms should separate into thin, stringy pieces that resemble crab meat.
- In a mixing bowl, combine the shredded mushrooms, mayonnaise, lemon juice, Old Bay seasoning, and paprika. Mix gently to coat.
- Fold in the diced celery and chopped chives. Season with salt and pepper to taste.
- Lightly butter the cut sides of the rolls and toast them in a skillet over medium heat for 1-2 minutes until golden.
- Divide the mushroom mixture evenly among the four rolls. Serve immediately while the rolls are still warm.
