01 - Preheat your oven to 375°F.
02 - In a large skillet over medium heat, cook the ground beef and sausage until thoroughly browned. Drain excess fat. Add the onion and garlic, sautéing until softened, about 3 minutes. Stir in the marinara sauce, dried basil, dried oregano, salt, and pepper. Simmer for 5 minutes, then remove from heat.
03 - In a medium bowl, combine the ricotta cheese, eggs, a pinch of salt, and half of the grated Parmesan. Stir until well blended.
04 - Scatter half of the shredded mozzarella over the bottom of the pie crust. Arrange 4 cooked lasagna noodles over the cheese, trimming as needed to fit the dish.
05 - Spread half of the ricotta mixture over the noodles, then top with half of the meat sauce. Repeat with the remaining noodles, ricotta mixture, and meat sauce.
06 - Finish by sprinkling the remaining mozzarella and Parmesan evenly over the top.
07 - Cover the edges of the crust with foil to prevent overbrowning. Bake for 40-45 minutes until the top is bubbly and golden.
08 - Allow the pie to cool for 10 minutes before slicing and serving.
