Crab Stuffed Portobello Mushrooms

These crab stuffed portobello mushrooms are a prime example of a decadent–yet healthy–meal that can come together with minimal effort.

A quick mixture of lump crab meat is stuffed into portobello mushroom caps, then baked until it is golden brown on top, while the mushroom beneath is juicy and tender.

What is a Portobello Mushroom?

Portobellos may sound like a unique mushroom strain, but they are just a larger, mature version of cremini mushrooms.

Up until recently these oversized cremini were tough to sell. Surprisingly, they often ended up being thrown away.

Thanks to some clever marketing in the late 1980’s however, the mushrooms were re-branded as “portobellos.” Now they are one of the most popular mushrooms in the world.

The dense, meaty texture of the Portobello holds up extremely well to baking or grilling. They also make a great vehicle on which to load other tasty ingredients.

You say portobello, I say portabella: The spelling and origin of the word portobello is a bit of a hot debate in the mycological world. In the end, it doesn’t matter if what ‘s on the label is spelled with an a or an o–both words refer to the same mushroom.

How to Make Stuffed Portobello Mushrooms with Crabmeat

Start by using a damp cloth or paper towel to gently wipe any dirt or debris off of the caps and gills.

Use a paring knife to cut the stem out of each cap.

In a large mixing bowl, combine a pound of crab meat with some egg, mayo, almond flour, onion, red pepper, Old Bay seasoning, salt, and pepper.

Stuff the mushrooms with the crab mixture. Sprinkle more almond flour on top of the mixture, then drizzle a little olive oil over the mushrooms. 

Bake the mushrooms in a preheated 375°F oven for 25-30 minutes until the tops are golden brown.

I like to serve the stuffed portobello mushrooms with a simple spinach salad to make a complete meal. Enjoy!
