Assemble this easy ravioli casserole with frozen ravioli, marinara sauce, and cheese, then pop it straight into the oven. No thawing, no boiling, no fuss. With just 5 minutes of prep and 4 simple ingredients, it's a cozy, family-friendly dinner that comes together on even the busiest nights.
2cupsshredded mozzarella cheese or Italian cheese blend
¼cupgrated Parmesan cheese
Optional garnish: chopped fresh herbs such as parsley, basil, oregano, or thyme
Instructions
Preheat oven to 400°F. Spray a 9x13-inch baking dish (or two 8-inch dishes) with cooking spray. Pour a thin layer of marinara sauce into the bottom of the dish (about ½ cup) to cover.
Arrange half of the frozen ravioli in a single layer over the sauce. Try to keep them flat and even so everything cooks at the same rate.
Top with half of the remaining marinara sauce and half of the mozzarella cheese.
Repeat the layers: remaining ravioli, remaining sauce, remaining mozzarella. Sprinkle Parmesan evenly over the top.
Cover tightly with aluminum foil. Bake for 20 minutes. Remove foil and bake uncovered for 20-25 more minutes, until the casserole is hot and bubbly, the cheese is golden, and the ravioli is tender when pressed lightly in the center.
Let stand for 10 minutes before serving. This rest time lets the layers settle so the casserole scoops out cleanly. Garnish with fresh herbs, if desired.

Notes
Don't thaw the ravioli. Use it straight from frozen. It cooks through in the oven and holds its shape better when layered.
Sauce quality matters. With only 4 ingredients, the marinara carries a lot of the flavor. A quality jar (like Rao's) makes a noticeable difference. Don't skimp on the layers. There's no added water in this recipe, so the sauce is what keeps the ravioli from drying out.
Cover tightly. A snug foil seal traps the steam the ravioli needs to cook through evenly, especially in the center layers.
Let it rest. 10 minutes off the heat lets the layers set; it scoops out much more cleanly.
Ravioli varieties: Cheese, spinach, or meat-filled all work well. Stick with standard-sized ravioli for even cooking; mini ravioli may finish a few minutes sooner.
Half batch: Cut all ingredients in half and bake in an 8-inch square pan. Check a few minutes early as baking time may be slightly shorter.
Make ahead / freeze: Assemble through Step 4, cover tightly, and freeze for up to 3 months. Bake straight from frozen, adding extra time as needed.
Storage: Refrigerate leftovers in an airtight container for 3-4 days. Freezing already-baked leftovers is not recommended (the pasta texture suffers when thawed).
Reheat: Cover with foil and warm in a 350°F oven for 15-20 minutes, or microwave individual portions for about 1 minute.
