This is lasagna by function rather than by noodle shape. Cheese ravioli already contains the tender pasta and dairy filling that a conventional pan asks you to assemble separately. Layer it with a hot garlicky beef sauce and shredded cheese, and the casserole still lands with the familiar pull of tomato, meat, pasta, and a browned top.
The decisive ingredient may be the least glamorous one: water. It thins the jarred sauce enough to cook the ravioli under foil. Once the pasta is tender, the cover comes off and the oven concentrates everything back toward a scoopable, bubbling bake. Nothing needs pre-boiling, and nothing needs an invented extra sauce.
“Ground Beef, pasta sauce and cheese are layered and baked together.”
Ravioli is the shortcut
Filled pasta supplies both the noodle and the cheese layer. It goes into the dish refrigerated or frozen, never pre-boiled.
Water has a job
One and a half cups loosen the prepared sauce so the covered pan can steam the ravioli tender instead of drying around it.
Foil first, bubble last
The covered interval cooks the pasta; the uncovered interval concentrates the sauce and colors the cheese. Keep the order intact.
