• Speed: Ready in about an hour with just a few minutes of prep.
• Simplicity: Pantry-friendly ingredients and minimal tools required.
• Comfort: All the cozy flavors of lasagna with much less work.
• Flexible: Use your favorite jarred sauce and any ravioli filling you prefer.

Ingredients

Use the ingredient list below exactly as written for best results. Quantities are important to preserve the texture and sauciness this casserole is known for.

• 1 25-ounce jar pasta or marinara sauce
• 1 25-ounce package frozen or fresh ravioli
• 3 cups shredded mozzarella cheese
• 3 tablespoons shredded parmesan cheese
• chopped parsley

Notes on ingredients

Pick a pasta or marinara sauce you enjoy; a herb-forward sauce with basil and garlic complements the cheese nicely. For the ravioli, any variety works — cheese, spinach and ricotta, or a meat-free filling if you prefer something heartier. Both frozen and fresh ravioli will work; frozen may need a touch more baking time. Use a good-quality shredded mozzarella that melts smoothly and a finely shredded parmesan for even coverage. Fresh chopped parsley at the end brings fragrance and color.

Equipment

• 9×13-inch baking dish (or similar size)
• Large spoon or spatula
• Measuring cups and spoons
• Aluminum foil (optional)
• Oven mitts

Step-by-step instructions

The recipe directions below have been rewritten into clear, step-by-step wording to make the process as smooth as possible. Follow them in order to ensure the dish cooks evenly and the cheese melts to creamy perfection.

1. Preheat the oven: Set your oven to 375°F (190°C) and allow it to fully preheat while you assemble the casserole. This ensures even cooking from the moment the dish goes into the oven.
2. Prepare the baking dish: Choose a 9×13-inch baking dish or one with similar capacity. If desired, lightly coat the bottom with a thin layer of sauce or a small drizzle of oil to prevent sticking.
3. Layer one – sauce base: Pour about one-third of the 25-ounce jar of pasta or marinara sauce into the bottom of the baking dish and spread it into an even layer. This creates a saucy base so the ravioli do not stick and helps the casserole stay moist.
4. Add the ravioli: Arrange the entire 25-ounce package of frozen or fresh ravioli in a single layer over the sauce. Place them close together but not piled—if your ravioli are stacked in the package, separate them so they lie flat. If you have frozen ravioli, lay them directly from the package into the dish; there’s no need to thaw.
5. Top with sauce: Spoon the remaining sauce from the jar evenly over the top of the ravioli. Make sure each ravioli has some sauce coverage so the centers steam and heat through. Use all of the leftover sauce so the casserole is fully sauced.
6. Add the mozzarella: Sprinkle 3 cups shredded mozzarella cheese evenly across the sauced ravioli. Distribute the cheese so it covers the surface and seeps between ravioli gaps for melty, gooey pockets.
7. Finish with parmesan: Scatter 3 tablespoons shredded parmesan cheese over the mozzarella layer. The parmesan adds a nutty, salty top note and encourages browning.
8. Optional covering: If you prefer a softer top or want to prevent excessive browning, tent the dish loosely with aluminum foil for the first portion of baking. Removing the foil toward the end allows the cheese to brown beautifully.
9. Bake the casserole: Place the baking dish in the preheated oven and bake for 30–35 minutes. If your ravioli were frozen, baking time toward the higher end of the range helps ensure they heat through. Remove the foil for the final 5–10 minutes if you tented the dish, so the cheese bubbles and turns golden.
10. Check for doneness: The casserole is done when the sauce is bubbling around the edges, the cheese is thoroughly melted, and the ravioli are hot in the center. If a fork inserted into a ravioli meets resistance, return to the oven for a few more minutes and check again.
11. Rest briefly: Once baked, remove the dish from the oven and let it rest for 5–10 minutes. This helps the sauce settle and makes the casserole easier to slice and serve.
12. Garnish and serve: Sprinkle chopped parsley over the top for freshness and color. Cut the casserole into portions and serve warm, spooning extra sauce from the dish over each serving.

Timing

Total time: about 50–60 minutes (10–15 minutes prep, 30–35 minutes bake, 5–10 minutes rest). Frozen ravioli may require the full 35 minutes of baking to ensure they’re heated through.

Serving suggestions

• Serve with a crisp green salad dressed in a tangy vinaigrette to cut through the cheese.
• Garlic bread or warm dinner rolls make the meal extra comforting.
• Finish with a sprinkle of red pepper flakes if you like a touch of heat, or add a drizzle of extra virgin olive oil and a few grinds of black pepper at the table.

Make-ahead and storage

To make ahead, assemble the casserole up to the cheese-topped step, cover tightly with plastic wrap or foil, and refrigerate for up to 24 hours. When ready to bake, remove the wrap, let the dish sit at room temperature for 15–20 minutes, and then bake as directed. You may need an extra 5–10 minutes of baking time if chilled through.

Leftovers keep well in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the whole dish in a 350°F (175°C) oven until heated through, about 15–20 minutes. Cover with foil to prevent the cheese from drying out while reheating.

Tips for success

• If you love a saucier casserole, use an extra-quarter cup of sauce on top before baking.
• For a crispier top, finish under the broiler for 1–2 minutes, watching closely so the cheese doesn’t burn.
• If using very large or stuffed ravioli, arrange them snugly so they support one another and don’t tip while baking.
• Fresh parsley should be added after baking to preserve its bright color and fresh flavor.

Variations

Here are a few simple ways to vary the recipe while keeping things easy:

• Add sautéed mushrooms, spinach, or roasted vegetables between the sauce and ravioli for extra texture and flavor.
• Stir a handful of shredded mozzarella into the sauce before layering for extra cheesiness throughout.
• Swap out part of the mozzarella for provolone or fontina for a different melt and flavor profile.
• Sprinkle a few tablespoons of breadcrumbs mixed with a little olive oil and parmesan on top for a crunchy finish.

Troubleshooting

If the center is undercooked while the edges are browning, cover the dish with foil and continue baking until the center is hot. If the cheese browns too quickly, tent the dish with foil to slow the browning while the centers finish heating.

Why this works

Traditional lasagna takes time because of layered pasta, meat, and ricotta. This Lazy Ravioli Lasagna Recipe (Easy Casserole) simplifies that process by using pre-filled ravioli as the pasta-and-cheese layer. The jarred sauce seals in moisture and flavor, while the generous cheese topping creates the gooey, browned finish we all love. It’s the same comforting flavor profile as lasagna but much faster and friendlier to weeknight schedules.
