Method
- Preheat oven to 375°F (190°C).
- If using regular lasagna noodles, cook them according to package directions until al dente. Oven-ready noodles do not require pre-cooking.
- Prepare the Béchamel Sauce: In a large saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, until a smooth paste forms (roux). Gradually whisk in the milk, a little at a time, smoothing out any lumps before adding more. Bring to a simmer, stirring constantly, and cook for 5-7 minutes, until thickened. Remove from heat and stir in salt, nutmeg, and white pepper. Set aside and keep warm.
- Prepare the Cheese Filling: In a medium bowl, combine ricotta cheese, Parmesan cheese, Mozzarella cheese, egg, parsley, salt, and pepper. Mix well.
- Prepare the meat sauce: Heat olive oil in a large skillet over medium heat. Add Italian sausage and cook, breaking it up, until browned. Add chopped onion and minced garlic and cook until softened, about 5 minutes. Drain excess grease. Season with salt and pepper.
- Assemble the Lasagna: Spread a thin layer of béchamel sauce on the bottom of a 9x13 inch baking dish.
- Arrange a layer of lasagna noodles over the sauce, overlapping as needed.
- Spread half of the cheese filling over the noodles.
- Sprinkle half of the sausage mixture over the cheese filling.
- Drizzle with about 1/3 of the remaining béchamel sauce.
- Repeat layers: noodles, remaining cheese filling, remaining sausage mixture, 1/3 of the béchamel sauce.
- Top with a final layer of noodles, the remaining béchamel sauce, and the remaining mozzarella cheese and parmesan cheese.
- Bake the Lasagna: Cover the baking dish with aluminum foil and bake for 30 minutes.
- Remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown and bubbly.
- Let the lasagna rest for at least 10-15 minutes before slicing and serving.
Notes
For a vegetarian version, skip the sausage and add roasted vegetables. To prevent runny lasagna, drain the sausage well and let the lasagna rest after baking. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat in the microwave or oven.
