Prep
- Preheat oven to 375 degrees F. Lightly grease a 9x13 inch baking dish with olive oil or cooking spray.
Make the Sauce
- In a large skillet over medium-high heat, cook the Italian sausage, breaking it up with a wooden spoon, until browned and cooked through, about 6-8 minutes. Drain excess fat if needed.
- Add minced garlic and oregano to the skillet; cook 1 minute until fragrant. Pour in marinara sauce, reduce heat to low, and simmer for 5 minutes to meld flavors.
Mix the Cheese Filling
- In a mixing bowl, stir together ricotta, egg, chopped basil, and 1 cup of the shredded mozzarella until well combined.
Assemble and Bake
- Spread 1 cup of meat sauce on the bottom of the prepared dish. Arrange half the ravioli in a single layer. Spread half the ricotta mixture over top, then 1.5 cups meat sauce. Repeat layers: remaining ravioli, ricotta mixture, and sauce. Top with remaining 1 cup mozzarella and the Parmesan.
- Cover tightly with foil and bake 25 minutes. Remove foil and bake 10-15 minutes more until cheese is melted, bubbly, and starting to brown in spots. Let rest 10 minutes before serving.
Notes
Use fresh refrigerated ravioli, not frozen, for best texture - it cooks perfectly as the lasagna bakes. Swap the sausage for ground beef or turkey, or use spinach ravioli and double the cheese for a meatless version. Assemble the night before, cover, and refrigerate; add 10 minutes to the covered baking time.
