Heat oil to medium heat.
From there add them to a gallon bag of flour and shake. Add back to the milk, making sure all sides are wet. Finally, add them to a bag of breadcrumbs. Shake around. Repeat with the remaining ravioli.
Add to oil and fry until golden brown. Place on a paper towel-lined plate to help drain the oil. Sprinkle with Parmesan cheese.
Repeat the process until all the pieces are breaded and fried. Serve immediately.
