01 - Preheat oven to 375°F. Line a baking sheet with foil and set aside.
02 - In a large skillet over medium heat, cook ground beef and sausage until browned throughout. Drain excess fat. Add onion and 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 evenly blended.
04 - Scatter half of the mozzarella cheese 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 mixture evenly over the noodles, followed by half of the meat sauce. Repeat with remaining noodles, ricotta mixture, and meat sauce.
06 - Sprinkle the remaining mozzarella and Parmesan cheese over the top layer.
07 - Cover edges of the pie crust with foil to prevent overbrowning. Bake for 40-45 minutes until bubbly and golden on top.
08 - Remove from oven and let cool for 10 minutes before slicing into wedges and serving.
