Crab Stuffed Mushrooms

Crab Stuffed Mushrooms are always a hit at any party or potluck. They’re full of seafood flavor and the stuffing is the perfect blend of crispy and creamy.

Something about crab meat makes any occasion special, and this mouthwatering appetizer is no exception.

The umami taste of the mushrooms blend perfectly with the seasoned sweet crab meat, savory diced onion and peppers, and the sharp taste of the freshly grated parmesan cheese.

With little prep work, this appetizer is ready in just half an hour… but it tastes like it took all day.

These mushrooms are an easy way to impress family and guests alike!

Serve them up with other savory appetizers like Instant Pot Cheese Dip or Air Fryer Cabbage or pair them with a sweet dessert like Cinnamon Roll Peach Cobbler or a seasonal Pumpkin Roll.

3. Add the butter, onion, seafood seasoning, salt, crab meat, egg, breadcrumbs, grated Parmesan cheese, and chopped green bell pepper in a large bowl and mix until well combined.

Tips and Variations

• Use gluten-free breadcrumbs and increase the butter to 3 tablespoons to create a gluten-free recipe.
• The recipe has not been tested with imitation crab meat, so we aren't sure how it may change the taste, texture or cook time.
• Lightly spray tops of stuffed mushrooms with cooking spray to assist with browning and to create a crispy topping.
• The stems and cores can be chopped into small pieces and added to the filling if you’d like.
• Any leftover filling can be used to make stuffed flounder, cod, or salmon.

Storage and Reheating

Storage: We don’t recommend storage as the mushrooms can get soggy. However if you'd like to the store the baked mushrooms, they will stay fresh in an airtight container in the fridge for up to 2 days.

Make Ahead: Crab stuffed mushrooms can be stuffed a day or two ahead of time and wrapped tightly in plastic wrap. When you're ready to bake them, simply unwrap, place in a baking pan, and cook as directed.

Freezing: If you are looking for a freezer option, prepare the stuffed mushrooms as directed but do not bake. Store in a freezer safe container for up to 3 months. Thaw in the refrigerator and bake as directed. We don’t recommend freezing already cooked stuffed mushrooms.

Reheating: When reheating, warm in the oven until heated through.
