Ingredients

The basic ingredients to make this stuffed mushroom recipe are:

• Mushrooms. Look for a small-medium sized mushroom. Baby Bella mushrooms, basically mini portobello mushrooms, are also known as “cremini mushrooms“.  They have a stronger and meatier flavor than button mushrooms and are a beautiful brown color. Button mushrooms, or “white mushrooms,” are very commonly found all over 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.
• Crabmeat. 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. More cheesy deliciousness with 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.

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 Crab Stuffed Mushrooms

Here are the step-by-step instructions to make these crab stuffed mushrooms:

Prepare the Mushrooms

Clean the mushrooms with a damp paper towel to remove any dirt and debris. (Avoid soaking them in water as this will dilute their flavor. )

Remove the mushroom stems from the mushrooms by pulling them to one side and then snapping them off. You can also use a knife to cut them off if the stems do not snap easily.

Place the mushrooms on a large baking sheet that has been lined with parchment paper. 

Crab Meat Filling

Mix together cream cheese, mayonnaise, ¼ cup Parmesan cheese, garlic, paprika, red pepper flakes, lemon juice, salt, and pepper.

Add crabmeat and green onions.  Mix delicately until just combined so the crabmeat does not break apart too much.

Bake in Oven

Use a spoon to 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.

Whisk together 2 tablespoons Parmesan cheese with 2 tablespoons of breadcrumbs.  Sprinkle about a teaspoon over each filled mushroom.

Bake in preheated 375°F oven for 20 minutes, or until the tops become crispy and golden brown.

Meal Prep and Storage

• To Prep-Ahead: One of the best things about this recipe is that it is so simple to prepare it ahead of time. Make the filling with or without stuffing the mushrooms, but bake within 24 hours.
• To Store: Place leftovers in an airtight container and keep in the fridge for up to 2 to 3 days.
• To Freeze: Freeze unbaked stuffed mushrooms in a single layer on a baking sheet for a few hours. Transfer them to a freezer-safe container and keep for up to 3 to 6 months.
• To Reheat: Warm these back up in the oven for the best texture.
