Ingredients (Serves 24)
24 large brown mushrooms

¾ lb crabmeat

2 tablespoons fresh lemon juice

½ cup panko bread crumbs

½ cup unsalted butter, melted

½ cup Parmesan cheese, grated (divided)

3 teaspoons Dijon mustard

2 teaspoons horseradish

1 teaspoon garlic powder

½ teaspoon onion powder

2 tablespoons fresh parsley, chopped

Instructions

1. Preheat Oven & Prep Pan
Preheat oven to 375°F (190°C). Lightly grease an 8×13-inch baking dish.

2. Make the Filling
In a large bowl, combine the crabmeat with lemon juice. Stir in the panko, melted butter, half of the Parmesan, Dijon mustard, horseradish, garlic powder, and onion powder. Mix gently until well combined.

3. Stuff the Mushrooms

Remove stems from the mushrooms. Fill each cap generously with the crab mixture using a spoon or small scoop.

4. Bake
Arrange mushrooms in the prepared baking dish. Sprinkle with the remaining Parmesan. Bake for 15–20 minutes, until mushrooms are tender and the filling is golden.

5. Serve
Garnish with chopped parsley and serve warm.

Tips for the Best Stuffed Mushrooms
Use fresh crabmeat for the best flavor, though canned or imitation crab can be substituted in a pinch.

Don’t overbake—you want the mushrooms tender but not mushy.

Make ahead option: Prepare the filling and stuff the mushrooms up to a day ahead, then bake just before serving.

These crab stuffed mushrooms are a crowd-pleasing appetizer that’s both savory and satisfying—perfect for any occasion.

The Anatomy of a Perfect Stuffed Mushroom

To achieve that golden-brown, cheesy crust and tender interior, selection and preparation are key:

• The Mushroom Base: Choose medium-to-large white button or cremini mushrooms. They should be firm and uniform in size to ensure they cook at the same rate.

• The Filling: High-quality lump crab meat is the star here. It is folded into a mixture of cream cheese, aromatics, and herbs to create a rich, savory center.

• The Topping: A blend of melted cheeses—typically cheddar or mozzarella—creates a beautiful, bubbly finish that locks in the moisture.

Recipe: Savory Crab Stuffed Mushrooms

Yields: 24-28 mushrooms

Prep time: 20 minutes

Cook time: 20 minutes

Ingredients

• 24-28 large white or cremini mushrooms

• 8 oz lump crab meat, drained and picked for shells

• 8 oz cream cheese, softened

• 1/2 cup shredded cheddar or mozzarella cheese

• 1/4 cup green onions, finely chopped

• 2 cloves garlic, minced

• 1 tsp Worcestershire sauce

• 1/2 tsp Old Bay seasoning or paprika

• 1/4 cup Panko breadcrumbs (optional, for extra crunch)

Instructions

1. Prepare the Mushrooms: Clean the mushrooms with a damp paper towel. Gently pop out the stems to create a hollow "cap" for the filling. Set the caps aside on a parchment-lined baking sheet.

2. Mix the Filling: In a medium bowl, combine the softened cream cheese, garlic, green onions, Worcestershire sauce, and seasonings. Once smooth, gently fold in the crab meat to keep the lumps intact.

3. Stuff the Caps: Using a small spoon or a piping bag, generously fill each mushroom cap with the crab mixture.

4. Add the Cheese: Top each mushroom with a generous pinch of shredded cheese. If using breadcrumbs, sprinkle those on last.

5. Bake: Place in a preheated oven at 375°F (190°C) for 18–22 minutes.

6. Garnish and Serve: The mushrooms are done when the caps are tender and the cheese on top is golden and bubbling. Let them rest for 5 minutes before serving to allow the filling to set.

Pro-Tips for Success

• Avoid Sogginess: Mushrooms release moisture as they cook. To prevent a watery tray, avoid washing them under running water; a damp cloth is all you need.

• Flavor Boost: For a deeper flavor, sauté the minced mushroom stems with a bit of onion and add them back into the cream cheese filling.

• Make-Ahead: You can stuff these mushrooms up to 24 hours in advance. Simply keep them covered in the refrigerator and pop them into the oven right before your guests arrive.

By following these steps, you’ll serve an appetizer that isn't just a snack, but a centerpiece of flavor and texture that your guests will be talking about long after the last bite is gone.
