These crab stuffed mushrooms are mushroom caps filled with flaked crab and three types of cheese, then baked to golden brown perfection. An easy and elegant appetizer that can be assembled ahead of time!

Whenever I’m entertaining, I like to put out a hearty spread of appetizers including favorites such as a relish tray, garlic parmesan wings, shrimp cocktail, baked chicken wings and BLT dip. Stuffed mushrooms are always a great addition to any menu and they’re a total crowd pleaser.

Stuffed mushrooms are an appetizer that have been popular for decades, and for good reason! They’re bite sized, look fancy and are so very delicious. These crab stuffed mushrooms involve a bit of decadence with real crab, plenty of cheese, and herbs and spices.

Seafood can make for an elegant appetizer. Along with these mushrooms I love to serve delicious morsels like Mexican shrimp bites, Maryland crab cakes and popcorn shrimp. If you want more options, feel free to check out all of my appetizers!

Crab Stuffed Mushrooms Ingredients

This recipe calls for mushrooms, butter, onions, garlic, lump crab meat, three types of cheese, chives and panko breadcrumbs.

How Do You Make Crab Stuffed Mushrooms?

This recipe starts with mushroom caps. You’ll want to remove the stems by popping them out with your fingers. Fill the mushrooms with a stuffing mixture of crab, cream cheese, garlic, onion, chives, parmesan and mozzarella cheese. Add a buttery breadcrumb topping to the filled mushrooms. Place the mushrooms on a baking sheet or in a baking dish, then bake until them until they are tender and the filling is heated through. Add a garnish of chives, then serve immediately.

Tips For Crab Stuffed Mushrooms

  • Don’t have chives on hand? Try green onions or parsley instead.
  • It’s best to grate your own cheese if possible. The pre-grated cheese from the grocery store often contains preservatives and anti caking agents and does not melt as well.
  • I top my mushrooms with crispy panko crumbs because I like the added texture. If you’re trying to make these mushrooms keto or low carb, skip the breadcrumb topping.
  • Choose your favorite type of mushroom for this recipe. I often use cremini mushrooms (baby bella mushrooms), but white button mushrooms are also a great choice. You can use larger portobellos if you prefer, and turn this into a light entree with a larger sized portion.
  • Leftovers will stay fresh in an airtight container for up to 2 days. Reheat the mushrooms in the oven at 350 degrees F for 7-8 minutes or until heated through.

Quick Tip

I prefer to use real crab meat in this recipe. I use frozen crab meat, or refrigerated fresh crab meat from my seafood counter. If you can’t find real crab meat, you can use imitation crab.

Recipe FAQs

How long do you bake stuffed mushrooms?

Crab stuffed mushrooms need to bake for about 20 minutes. The mushrooms are done when the tops are crispy and browned and the mushroom caps are cooked all the way through.

What kind of mushrooms are best for stuffed mushrooms?

I like to use regular white button mushrooms or cremini mushrooms for my stuffed mushrooms. The mushrooms shown here are cremini mushrooms which have a stronger flavor than white mushrooms. You can also use large portobello mushrooms if you’re looking for an entree sized stuffed mushroom. Be sure to choose mushrooms that are roughly the same size so that they cook evenly.

Can you make crab stuffed mushrooms in advance?

You can assemble your stuffed mushrooms up to 6 hours before you plan to serve them. Store your mushrooms loosely covered in the fridge, then pop them in the oven right before you’re ready to eat.

What cheese is best for crab stuffed mushrooms?

I use three types of cheese in these mushrooms: cream cheese, parmesan cheese and Monterey Jack cheese. The cream cheese acts as a binder, and the parmesan imparts a nutty flavor. I also used grated Monterey Jack cheese as I wanted a mild, creamy cheese that wouldn’t overpower the flavor of the crab. Other great options are fontina or cheddar cheese.

How do you clean mushrooms?

The best way to clean mushrooms is to use a damp paper towel to gently rub each mushroom. You can also rinse your mushrooms in a colander, but be sure to rinse them briefly; do not soak them in water.

Flavor Variations

While this recipe is delicious as-is, you can add other ingredients to customize the flavors to your tastes.

  • Protein: No crab on hand? You can also use chopped shrimp, lobster or even diced smoked salmon. I also sometimes like to add a little bacon for a smoky kick.
  • Vegetables: Feel free to add more veggies to the filling. Some great options include sauteed spinach, bell peppers, water chestnuts or marinated artichoke hearts.
  • Seasonings: Add some additional flavor with finely diced olives, fresh parsley, black pepper, fresh basil, hot sauce, Old Bay seasoning or even Italian seasoning.

Whenever I’m having a party, I make a double batch of these mushrooms. They’re always the first appetizer to go, and you can never eat just one! The flavor is a cross between roasted mushrooms and crab cakes, and it’s a unique way to serve your guests something special.
