What goes into the Crab stuffed mushroom recipe?

About the mushrooms

After you’ve got your filling ready to go, it’s time to stuff and bake the mushrooms!

A little tip about cleaning mushrooms

Mushrooms are like little sponges- which is great when you’re cooking with them for sopping up flavors- but something to be mindful of when cleaning and prepping them.

To clean mushrooms, simply wipe them clean with a (lightly) damp paper towel, as needed. Resist the urge to submerge them, or run them under water. The mushrooms texture will change for the worst- no bueno.

Stuffing the mushroom caps

After you have wiped all your little mushrooms clean with a damp paper towel, remove the stems, and place the mushrooms stem side up in a greased baking dish. Also- don’t throw away the stems! They are great chopped up in soups, stews and stuffings!

Next, stuff each mushroom generously with the crab mixture, and sprinkle lightly with old bay. Pour a bit of wine into the pan under the mushrooms t help flavor them and keep them from drying out- then pop them into a preheated oven. Bake for about 45 minutes, until golden and crispy- and serve with chopped chives and lemon wedges! Bon Appétit!
