Yes, this recipe can be made a frozen. You should thaw them in the refrigerator and you may want to warm them slightly before serving them..

I made these for a Baby Shower and received many compliments and requests for the recipe. I accidently used 3 times the mushrooms, but they were great! I will probably do it the same next time.
