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