Ravioli Lasagna Bolognese

Don't have the Ninja 4-in-1 Cooking System? Cook the ravioli in boiling water on the stovetop. Brown the beef with the onion, garlic, and black pepper in a separate pan. Combine the ravioli, beef mixture, and sauce in a baker and bake, covered, at 350°F for 30 minutes. Add the cheeses during the last 10 minutes.

Tip: This one-pot lasagna recipe couldn't be easier to make ahead of time. Just allow the finished dish to cool to room temperature and store it in the fridge overnight. If you want to freeze the lasagna for a longer period of time, separate it into chunks before storing.
