The easiest 3-ingredient dinner recipe you’ll ever make — under 5 minutes to prep!
This quick and easy dinner quickly becomes a weeknight go-to. With only three pantry-friendly ingredients, it’s budget-friendly, beginner-proof, and ready with minimal prep time. I keep these items on hand so I can throw the dish together when evenings get hectic. Leftovers reheat well and make an easy lunch, too.
A super simple dinner idea for busy parents — picky eaters approve!
I call this baked ravioli “lazy lasagna” because the layered assembly and bubbling cheese deliver the same comforting flavors as lasagna without all the work. The oven concentrates the sauce and browns the cheese, giving each bite rich, toasty flavor. It’s an ideal option for nights when you want something warm and satisfying but don’t have time or energy for a long recipe.
This three-ingredient casserole is cheap, fast, and delicious. It’s perfect for families, dorms, or anyone who wants a hearty meal without fuss. You can customize it easily with additional fillings or toppings, but the basic version is so good on its own that even picky kids usually ask for seconds.
Lazy Lasagna (Cheesy Baked Ravioli)
This simple, cost-effective dinner uses just frozen ravioli, jarred pasta sauce, and shredded mozzarella. It bakes into a cheesy, comforting casserole that’s perfect for busy weeknights and families with picky eaters. Prep takes minutes and the oven does the rest.
Ingredients
- 1 (25 oz) bag frozen ravioli (any variety)
- 1 (24 oz) jar pasta sauce
- 2 cups shredded mozzarella cheese
- 1/3 cup grated parmesan, for sprinkling (optional)
Instructions
- Preheat oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish.
- Spread about 3/4 cup of pasta sauce across the bottom of the dish to form a thin layer.
- Arrange half of the frozen ravioli in a single layer over the sauce.
- Spoon half of the remaining sauce over the ravioli and sprinkle with half of the mozzarella.
- Repeat with the remaining ravioli, sauce, and mozzarella. If using, sprinkle parmesan over the top.
- Cover with aluminum foil and bake 30 minutes. Remove foil and bake another 12–15 minutes, until cheese is bubbly and lightly browned.
- Let rest 5–10 minutes before serving. Pair with garlic bread, a green salad, or steamed vegetables if desired.
Notes
- Swap ravioli filling to change the flavor: cheese, spinach, chicken, or meat-filled all work.
- Add layers of pepperoni, cooked sausage, browned ground beef, or sautéed vegetables to bulk it up.
- For a creamier version, replace some or all of the red sauce with Alfredo or a white sauce.
- Leftovers keep well in the fridge for 2–3 days and reheat nicely in the oven or microwave.
Why this works: frozen ravioli cooks in the oven while absorbing sauce, so you don’t need to boil it first. The cheese melts and browns, giving you a comforting, lasagna-like dish with minimal effort. Because the base ingredients shelf-stable or freezer-friendly, this recipe is ideal for last-minute meals or a simple weeknight rotation.
Tips for success: spread the sauce evenly under the first layer so ravioli doesn’t stick, and don’t skip the rest time after baking — it helps the sauce set and makes slicing easier. If your oven runs hot, keep an eye on the cheese after removing the foil so it doesn’t over-brown.
