Bring the fresh ravioli and the eggs to room temperature.
In a shallow bowl combine the panko, Italian seasoned bread crumbs, Italian seasoning, and kosher salt; mix well.
In a separate shallow bowl whisk together the eggs and milk until blended.
Dip each ravioli into the egg mixture, then dredge in the breadcrumb mixture to coat. Repeat the egg dip and breadcrumb dredge a second time for a double coating. Place coated ravioli on a wire rack while heating the oil.
Heat oil in a deep pot or large skillet to 350–375°F (175–190°C). Use enough oil to cover or shallow-fry the ravioli as preferred.
Fry the ravioli in batches, about 3 minutes total per batch, turning once halfway through so they brown evenly.
When golden and puffed, transfer ravioli to a rack or paper towels to drain briefly, then serve warm or at room temperature with warm marinara for dipping if desired.
