White button mushrooms (champignon) or cremini (baby bella) mushrooms work the best for this recipe. You can stuff portobellos too, but you will have to make more stuffing to fill this type of mushrooms.

For  demonstration purposes I used a small pack (8 oz) of white button mushrooms from the grocery store which contained 10 mushrooms. It was just the right amount for me and my husband to have them as a side dish for dinner. For holiday gatherings – at least quadruple the amount of ingredients.
