Double Stuffed Mushroom Caps

IMG_8805Mushroom caps have long been a staple on appetizer buffets, and rightly so! They’re easy to do, usually just a mouthful or two, a perfect finger food. They’re typically filled with cream cheese, maybe with some crab mixed in. Cheese seems to be in so many appetizers, so if there’s a way to hold back on the stuff (this is me talking, She Who Wants Cheese) I try to do it whenever possible. This recipe is full of umami, and can easily be adapted to be Gluten Free or Vegan (see following main recipe). I usually allow for 3 per person if they’re to be plated and served before the salad course. However, if they’re part of an appetizer buffet allow for 1 – 2 per person.  

Approximately 12 – 14 stuffed caps ~ enough for 4 – 6 servings ~ double as necessary


1 lb. of 1½”- 2” firm white or brown mushrooms – stalks should still connect to the caps

½ medium onion – coarsely chopped

2 cloves garlic – coarsely chopped

1 T oil + some for drizzling

¼ red pepper – cored & finely diced

½ c Italian parsley – minced

salt & pepper

2 oz grated Parmesan (56 gr) Yes, there is a bit of cheese…

Panko crumbs


Brush the mushrooms clean with a dry cloth.IMG_8780

Remove the stalks by gently pushing away from you, and then pulling towards you. They should make a “thwuck-thwuck” sound. Reserve the stalks.IMG_8781

Arrange the caps top down on a parchment lined baking sheet. They can be quite close together, but shouldn’t touch. The little bit of space helps to stop them from steaming when they should be roasting.

Coarsely chop the stalks.

Add the stalks to the bowl of a processor. Process until minced. Remove to a bowl, reserve.IMG_8784

Add the onion & garlic to the processor (no need to rinse out from the mushrooms), and process until minced.

Heat the oil in a large skillet over medium high heat.

Add in the onion and garlic and cook for about 3 minutes until they are softened and there are a few browned bits.


IMG_8787Stir in the red pepper, and continue cooking for another 2 minutes.IMG_8789

Stir in the mushrooms, and continue cooking for another 2 minutes.

Stir in the parsley, and continue cooking for another minute.IMG_8792

Season with a bit of salt & pepper.

Remove to a bowl, and let cool for 15 minutes, stirring occasionally.IMG_8794

Preheat the oven to 375°

Once cooled, stir in the grated Parmesan.IMG_8795

Fill each of the caps with the filling, keeping the filling level with the opening, being sure it is well filled.IMG_8796

Loosely mound the remaining filling on top of each one.IMG_8797


Drizzle a little oil over all, being sure that each cap gets some.IMG_8799

Sprinkle a little Panko on each cap.

Bake at 375° for 18 minutes

Serve while hot.IMG_8803


Optional Topping:

While they’re baking, mix a topping of ⅓ c Greek yogurt and 1 teaspoon of minced chives.

Once the mushrooms are out of the oven, dollop each with a small spoonful of the topping, and serve. IMG_8807

Gluten Free: instead of Panko to top the mushrooms, use a bit of Parmesan

Vegan: replace Parmesan with some fine bread crumbs (about ½ a cup), adding  the breadcrumbs at the same time as when you add the minced mushrooms to the skillet. Don’t over stir, as you want to allow the crumbs to brown. Do not serve with the optional topping. Alternately, add in ½ cup of finely chopped green or black olives instead of the Parmesan or breadcrumbs.  Add into the mixture after it has been removed from the heat.
