Method
Preparation
- Bring a large pot of salted water to a boil. Cook lasagna sheets according to package directions until al dente. Drain and lay sheets flat on a lightly oiled tray so they don’t stick.
- Heat a skillet over medium. Add a splash of oil and cook chopped onion until translucent, 3-4 minutes. Add sausage and break it up; cook until no longer pink, 4-5 minutes.
- Stir in minced garlic, dried parsley, basil, and oregano; cook for 30 seconds until fragrant. Add both cans of tomato sauce, reduce heat to low, and simmer for 10-15 minutes to let flavors marry. Season with salt and pepper to taste.
- In a medium bowl combine ricotta, egg, reserved 1 cup mozzarella, reserved 1/4 cup Parmesan, and chopped spinach. Mix until smooth and well combined.
- Preheat oven to 350°F (175°C). Spread a thin layer of meat sauce across the bottom of a 9x13-inch baking dish to prevent sticking.
Assembly and Baking
- On each lasagna sheet, spread about 2-3 tablespoons of the ricotta mixture in an even layer, then spoon a thin layer of meat sauce over the filling. Roll each sheet tightly and place seam-side down in the dish.
- Pour remaining sauce over the arranged rolls. Sprinkle the remaining 1 cup mozzarella and 1/4 cup Parmesan over the top. Cover tightly with foil.
- Bake covered for 40 minutes. Remove foil and bake an additional 5 minutes to brown the cheese. Let sit 5-10 minutes before serving so the filling sets.
Notes
For a lighter filling, use part-skim ricotta or replace some ricotta with plain Greek yogurt (up to 1/3). Gluten-free lasagna sheets work; follow package boiling or baking instructions.
