Preheat the oven to 375°F (190°C). Line a cookie sheet with parchment paper and set aside.
In a shallow bowl whisk together the egg and milk until blended.
In a second shallow bowl combine the Italian bread crumbs and grated Parmesan cheese.
Working one at a time, dip each thawed ravioli into the egg mixture, letting excess drip off, then press into the breadcrumb mixture to coat both sides. Place coated ravioli in a single layer on the prepared baking sheet.
Lightly spray the tops of the coated ravioli with cooking spray to help them brown.
Bake for 12–15 minutes, or until the ravioli are golden brown and crisp. Serve immediately with warm marinara or pesto.
Air fryer option: arrange coated ravioli in a single layer and cook at 350°F (175°C) for 7–9 minutes, flipping once if needed.
Notes
You can use frozen or refrigerated ravioli; no precooking is needed.
Any ravioli variety works, cheese ravioli is a common choice.
Panko can be used if mixed with Italian seasoning.
Freshly grated Parmesan or the powdered can is preferred for coating.
To freeze: coat, freeze on a baking sheet, then transfer to a bag and bake from frozen adding a few minutes.
