Ingredients

The ingredients needed for this crab meat stuffed mushrooms recipe are easy to find at most grocery stores.  There are also a few substitutions you can make if you are dairy-free or have trouble finding some of them:

• Crab meat – Fresh crab meat or canned meat can be used interchangeably in this recipe.  However, the better the quality, the better the mushrooms will taste. Jumbo lump is the best type to use, but you can also use claw or finger meat if that’s all you can find.
• Cream cheese – The bulk of the filling is made up of this soft and creamy cheese.  If you’re dairy-free you can also try substituting with a vegan variety instead.
• Mayo – Another major component of the filling is this egg-based spread.  You can also use Miracle Whip, Avocado oil based mayo, or even a vegan substitute instead.
• Parmesan Cheese – We’re doubling down on the cheesy deliciousness by adding in this sharp and salty cheese.  Once again, if you’re dairy-free you can opt to use a vegan alternative or even a bit of nutritional yeast.
• Onions – Finely chopped green onions or chives give a nice bite to the filling mixture.
• Seasonings – A bit of crushed garlic, paprika, salt, and pepper combine to give the majority of the flavor to the crab meat filling.
• Breadcrumbs – Just before popping the mushrooms in the oven you’ll sprinkle on a combination of Parmesan cheese and Panko-style breadcrumbs to give them a crunchy bite.  If you’re gluten-free, look for the Aleia’s brand of breadcrumbs for the best results.

Best Mushrooms for Stuffing

If serving these mushrooms as a party appetizer or snack, you’ll want to look for a small-medium sized mushroom.

You can use the larger portobello mushroom for this recipe but you’ll need to cook them for about 5-10 minutes longer than the recipe calls for.

There are two types of mushrooms that are easy to find and work well for stuffing:

• Baby Bella mushrooms.  These are essentially miniature portobello mushrooms and are also referred to as “cremini mushrooms“.  They have a stronger and meatier flavor than button mushrooms and are a beautiful brown color.
• Button mushrooms.  Also otherwise known as “white mushrooms,” are the most commonly found mushroom throughout the United States.  These are a lighter color and have the least flavor.

Whichever variety you choose, you’ll need about 1 pound, or roughly 15 mushrooms.

Cook’s Secret:  Did you know portobello, cremini, and button mushrooms are actually all the same species of mushroom?  (Agaricus bisporus) The only difference is the amount of time they have been allowed to age.

How to Make

You can have these stuffed mushrooms ready to enjoy in less than 30 minutes.  Here are the step-by-step instructions.

Prepare the Mushrooms for Stuffing

1. Clean mushrooms with a damp paper towel to remove any dirt and debris. (step 1 above)
   • Avoid soaking them in water as this will dilute their flavor.
2. Remove the stems from the mushrooms by pulling them to one side and then snapping them off. (step 2 & 3 above)
   • You can also use a knife to cut them off if the stems do not snap easily. 
3. Place mushrooms on a large baking sheet that has been lined with parchment paper. 

Make the Crab Meat Filling

1. Mix together cream cheese, mayonnaise, ¼ cup Parmesan cheese, garlic, paprika, red pepper flakes, lemon juice, salt, and pepper. (step 1 above)
2. Add crabmeat and green onions.  Mix delicately until just combined so the crabmeat does not break apart too much. (step  2 above)

Bake in the Oven

1. Fill each mushroom cap with 1 to 1 ½ tablespoons of the crabmeat filling mixture. 
   • Pay careful attention not to fill them up with more filling than they are tall to prevent overflow while baking. (step  1 above)
2. Whisk together 2 tablespoons Parmesan cheese with 2 tablespoons of breadcrumbs.  Sprinkle about a teaspoon over each filled mushroom. (step  2 above)
3. Bake in preheated 375 °F oven for 20 minutes, or until the tops become crispy and golden brown.

Prep Ahead

One of the best things about this recipe is that they are extremely easy to prepare ahead of time.

• You can either stop after mixing the filling and store it separately from the mushrooms.  (You’ll want to do this if you’ll be storing them for more than 24 hours.)
• Or you can go ahead and fill up all of the mushrooms with the crab meat filling.  (You’ll want to bake them within 24 hours of filling.)

On the day of serving pull them out of the refrigerator at least 30 minutes before baking to let them come to room temperature.  Follow the directions outlined below as written.

FAQs

What is the best mushroom to use for stuffing?
