Cook the lasagna noodles according to the package instructions until al dente. Drain and set aside.
In a large skillet over medium heat, combine the ground beef and ground turkey. Cook until browned, breaking it up with a spatula.
Add the minced garlic to the meat mixture and cook for another minute until fragrant. Season with salt, pepper, and Italian seasoning.
Stir in the marinara sauce and let it simmer for about 5 minutes. Remove from heat.
In a separate bowl, mix the ricotta cheese with the egg, and season with a pinch of salt and pepper.
To assemble the lasagna, spread a thin layer of the meat sauce on the bottom of a 9x13 inch baking dish.
Place 3 lasagna noodles on top of the sauce, followed by half of the ricotta mixture, a third of the mozzarella cheese, and a third of the meat sauce.
Repeat with another layer of noodles, the remaining ricotta mixture, another third of the mozzarella, and another layer of meat sauce. Top with the final 3 noodles, the remaining meat sauce, and finish off with the remaining mozzarella and Parmesan cheese.
Cover the baking dish with aluminum foil to prevent burning and bake in the preheated oven for 25 minutes.
Remove the foil and bake for an additional 15-20 minutes, until the cheese is bubbly and golden.
Allow the lasagna to cool for about 10 minutes before slicing. Garnish with fresh basil leaves before serving.
Notes
Let the lasagna cool for a few minutes before slicing for cleaner pieces.
