Yes, you can! You could either assemble these the night before and store them in an airtight container to be fried the following day or freeze them assembled ahead of time and then cook them whenever the occasion calls for a delicious platter of stuffed poppers! To freeze ahead, assemble your stuffed poppers and then line them up on a cookie sheet with parchment paper. Allow them to freeze like this for 2 hours before placing them in a zip-lock bag so they don’t stick together.
