Preheat your oven to 375°F (190°C) to create a warm baking environment for the lasagna.
Cook the lasagna noodles as per the package instructions until they are al dente. Drain them well, and set aside to cool slightly.
In a medium mixing bowl, blend together the ricotta cheese, the beaten egg, half of the grated Parmesan cheese, the dried Italian herbs, along with salt and pepper. Mix until the ingredients are fully incorporated and creamy.
Pour a small amount of marinara sauce into the bottom of a 9x13 inch baking dish, spreading it evenly to prevent sticking.
Lay down 3 lasagna noodles over the sauce, ensuring they are neatly aligned. Spread half of the ricotta mixture over the noodles, smoothing it out with a spatula. If including protein, layer half of the cooked ground beef or turkey on top. Drizzle a layer of marinara sauce followed by a generous sprinkle of mozzarella cheese.
Create a second layer by adding another 3 noodles, spreading the remaining ricotta mixture over the top. If using meat, add another layer of the cooked ground beef or turkey, followed by more marinara sauce and another handful of mozzarella cheese.
For the final layer, arrange the last 3 noodles on top, then pour the remaining marinara sauce over them, generously sprinkling with mozzarella cheese and the remaining Parmesan cheese.
Cover the entire baking dish tightly with aluminum foil to trap steam during cooking, then place it in the preheated oven and bake for 25 minutes.
After 25 minutes, carefully remove the foil and continue baking for an additional 15 minutes, or until the cheese is beautifully bubbly and a golden brown color has formed on top.
Allow the lasagna to cool for approximately 10 minutes before carefully slicing into servings. For a lovely finishing touch, garnish with fresh basil leaves to enhance the presentation and aroma before serving.
Notes
Feel free to use store-bought marinara sauce for convenience.
