Can you skip roasting the mushrooms?

Cremini mushrooms have a unique flavor that is best extracted and enhanced when roasted. This is why we don’t recommend skipping this step. To clean the mushrooms, avoid rinsing or soaking them in water. Too much water can make the mushrooms turn soggy when baked. Instead, wipe them with a damp towel to get rid of any dirt. If your mushrooms are too dirty, then you can rinse them, but make sure you let them dry completely before cooking them. To achieve the best results, bake your mushrooms at a high temperature until they develop a dark golden color.

Can you adapt this recipe to a vegan diet?

Of course, you can! The only 2 ingredients preventing this recipe from being vegan are butter and heavy cream. You can swap out the butter for vegan butter or olive oil, and the heavy cream for coconut milk.
