The Ingredients

This recipe uses simple, wholesome ingredients that come together beautifully.

24 large brown mushrooms – The perfect vessel for the savory crab filling.
¾ pound crabmeat – Lump crabmeat is best, but claw meat works beautifully.
2 tablespoons fresh lemon juice – For bright, citrusy flavor.
½ cup panko bread crumbs – For a light, crispy texture.
½ cup unsalted butter, melted – For richness and to help the filling bind.
½ cup Parmesan cheese, grated, divided – For a salty, nutty finish.
3 teaspoons Dijon mustard – For tang and depth.
2 teaspoons horseradish – For a subtle, savory kick.
1 teaspoon garlic powder – For savory depth.
½ teaspoon onion powder – For warmth.
2 tablespoons fresh parsley, chopped – For a pop of color and freshness.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat the oven to 375°F. Line a baking sheet with parchment paper or lightly grease it.

Pro Tip: Parchment paper makes cleanup a breeze and prevents sticking.

Step 2: Prepare the Mushrooms

Clean the mushrooms with a damp paper towel. Remove the stems and finely chop them. Set the caps aside.

Pro Tip: Don’t wash mushrooms under running water—they absorb moisture and become soggy. Wipe them clean with a damp paper towel.

Step 3: Make the Filling

In a medium bowl, combine the crabmeat, chopped mushroom stems, lemon juice, panko, melted butter, ¼ cup of the Parmesan, Dijon, horseradish, garlic powder, onion powder, and parsley. Stir gently until evenly combined.

Pro Tip: Be gentle when mixing—you want to keep the crabmeat in nice chunks, not mash it into a paste.

Step 4: Stuff the Mushrooms

Spoon the filling into each mushroom cap, mounding it slightly. Place the stuffed mushrooms on the prepared baking sheet.

Pro Tip: Don’t overfill—the filling will expand slightly as it bakes.

Step 5: Top with Parmesan

Sprinkle the remaining ¼ cup of Parmesan cheese over the tops of the stuffed mushrooms.

Pro Tip: Be generous—the Parmesan bakes into a golden, crispy crust.

Step 6: Bake to Golden Perfection

Bake for 20-25 minutes, until the mushrooms are tender and the tops are warm, golden, and bubbling.

Pro Tip: Watch them closely toward the end—the cheese can go from golden to burnt quickly.

Step 7: Cool and Serve

Let them cool for 2-3 minutes before serving. Garnish with additional fresh parsley if desired.

Pro Tip: Serve warm or at room temperature. They’re delicious either way!
