Savory Crab Stuffed Mushrooms

Savory crab stuffed mushrooms are a perfectly elegant little bite that still feels cozy and comforting. Tender mushroom caps are piled high with buttery crab, crunchy panko, and just enough Dijon and horseradish to make the flavors pop. They’re ideal as a starter for a special dinner, a holiday appetizer, or something impressive to bring to a party. The best part is that they look fancy, but the steps are simple enough for any home cook to follow. Serve them hot from the oven and watch them disappear in minutes.

Ingredients

• 24 large brown mushrooms
• ¾ lb crabmeat
• 2 tbsp fresh lemon juice
• ½ cup panko bread crumbs
• ½ cup unsalted butter, melted
• ½ cup grated Parmesan cheese, divided
• 3 tsp Dijon mustard
• 2 tsp prepared horseradish
• 1 tsp garlic powder
• ½ tsp onion powder
• 2 tbsp fresh parsley, chopped

Directions

1. Preheat the oven to 375°F and lightly grease an 8 × 13-inch baking pan.
2. Clean the mushrooms, remove the stems, and arrange the caps cavity-side up in the prepared baking pan.
3. In a large bowl, add the crabmeat and drizzle with the lemon juice, then gently toss to coat.
4. Stir in the panko bread crumbs, melted butter, about ¼ cup of the Parmesan cheese, Dijon mustard, horseradish, garlic powder, onion powder, and parsley until well combined.
5. Use a small scoop or spoon to fill each mushroom cap generously with the crab mixture, mounding it slightly.
6. Sprinkle the remaining Parmesan cheese evenly over the tops of the stuffed mushrooms.
7. Bake for 15–20 minutes, or until the mushrooms are tender and the tops are lightly golden.
8. Remove from the oven and serve immediately while hot.

Tips

For the best texture, use lump or claw crabmeat and avoid overmixing so the crab stays in nice pieces instead of turning pasty; if the filling looks too loose, add a spoonful more panko to tighten it up.

If you’re making these ahead, fill the mushroom caps and refrigerate them (covered) for up to 8 hours, then sprinkle with the final Parmesan and bake just before serving; leftovers can be stored in an airtight container in the fridge for up to 2 days and reheated gently in a 325°F oven.

FAQ

Can I use canned crab instead of fresh?
Yes, you can use canned crab—just drain it very well and pick through to remove any bits of shell.

Do I have to use brown mushrooms?
No, white button or cremini mushrooms work just as well as long as they’re large enough to hold a spoonful of filling.

Can I make these spicy?
You can add a pinch of cayenne pepper, crushed red pepper flakes, or a dash of hot sauce to the crab mixture for a little heat.

How do I keep the mushrooms from getting soggy?
Don’t rinse them under running water—wipe them clean with a damp paper towel instead, and avoid overcrowding the pan so the moisture can evaporate while baking.

Can I freeze crab stuffed mushrooms?
It’s best to freeze them unbaked: fill the caps, freeze on a tray until firm, then transfer to a freezer bag; bake from frozen, adding a few extra minutes to the baking time.
