Why This Crab Stuffed Mushroom Recipe Works
Crab stuffed mushrooms are all about contrast.
You get:
- Juicy roasted mushrooms
- Sweet delicate crabmeat
- Crispy golden topping
- Creamy savory filling
- Bright citrus balance
Brown mushrooms are ideal because they have a deeper flavor than white mushrooms. That earthiness pairs perfectly with sweet lump crabmeat and sharp parmesan cheese.
The lemon juice cuts through richness and keeps the seafood flavor fresh.
Panko breadcrumbs create structure without heaviness, making this an ideal low-carb party food when paired with a light seafood filling.
Melted butter helps brown the tops and delivers that classic baked seafood flavor.
Dijon and horseradish add subtle depth without overpowering the crab.
The result is an elegant seafood appetizer that feels rich but never heavy.
Ingredients
- 20 large brown mushrooms, stems removed
- 8 oz lump crabmeat, well drained
- ½ cup panko breadcrumbs
- ¼ cup grated parmesan cheese
- 2 tablespoons melted butter
- 1 tablespoon Dijon mustard
- 1 teaspoon prepared horseradish
- 1 tablespoon lemon juice
- 1 tablespoon fresh parsley, chopped
- Salt and black pepper to taste
Step-by-Step Instructions
Step 1 — Prep the Mushrooms
Preheat oven to 400°F.
Wipe mushrooms gently with a damp paper towel.
Remove stems and lightly scrape gills if needed.
Arrange caps on lined baking sheet.
Step 2 — Make the Filling
In a bowl, gently mix:
- Lump crabmeat
- Panko
- Parmesan
- Melted butter
- Dijon
- Horseradish
- Lemon juice
- Parsley
- Salt and pepper
Do not overmix — keep the crab texture intact.
Step 3 — Fill the Mushrooms
Spoon filling generously into each mushroom cap.
Do not pack too tightly — a light mound bakes better.

Bake for 15–18 minutes.
Mushrooms should be tender.
Tops lightly golden.
Serve warm.
