Zucchini flowers can be stuffed with the ricotta cheese mixture and frozen up to 2 months in a sealed freezer safe container. However, we like to hold off on adding the panko breadcrumbs, so they stay crispy. On the day you want to bake or air fry. Prepare your herb panko bread crumb mixture and dip the stuffed squash blossoms in egg and roll in panko breadcrumbs. Bake or air fry as desired.
