There are many mushroom varieties out there and I love every one of them, with Morels being my favorite. Although Morels have a hollow center, they would not be my first choice for stuffing. Instead, I would use any of the following: Baby Bella Mushrooms White Button Mushrooms Cremini Mushrooms The above-mentioned mushrooms are the perfect size and shape for stuffing. So feel free to use any of the three in this recipe.
