Place the breadcrumbs on a plate or in a shallow bowl.
Dip each ravioli into the egg mixture, then roll into the breadcrumbs. Repeat the process with all of the raviolis. Place the raviolis in a single layer on the sheet pan.
Heat 3 inches of oil in a deep pot to 350 degrees F.
Add 6-8 ravioli to the pan, and fry for 3-4 minutes or until browned all over.
Repeat the process with the remaining raviolis.
Sprinkle with parmesan and parsley, and serve with marinara sauce for dipping.
