01 - Preheat oven to 375°F. Position the rack in the center of the oven.
02 - In a large skillet over medium heat, cook the ground beef and sausage until thoroughly browned, breaking apart with a spoon. Drain excess fat. Add the onion and garlic; sauté 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. Mix until smooth and well blended.
04 - Scatter half of the shredded mozzarella over the bottom of the pie crust. Layer 4 cooked lasagna noodles over the cheese, trimming them to fit the dish.
05 - Spread half of the ricotta mixture evenly over the noodles, then spoon half of the meat sauce on top. Repeat with the remaining noodles, ricotta mixture, and meat sauce.
06 - Sprinkle the remaining mozzarella and Parmesan evenly over the top.
07 - Cover the edges of the pie crust with foil to prevent overbrowning. Bake for 40–45 minutes until the top is bubbly and golden.
08 - Remove from the oven and let cool for 10 minutes before slicing into wedges and serving.
