01 - Preheat your 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 Italian sausage, breaking apart with a wooden spoon, until fully browned. Drain excess fat. Add the chopped onion and minced 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 and let cool slightly.
03 - In a medium mixing bowl, combine the ricotta cheese, eggs, a pinch of salt, and half of the grated Parmesan. Stir until smooth and 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 them to fit the dish.
05 - Spread half of the ricotta cheese mixture over the noodles, then spoon half of the meat sauce on top. Repeat with the remaining 4 noodles, the rest of the cheese mixture, and the remaining meat sauce.
06 - Sprinkle the remaining mozzarella and the rest of the Parmesan evenly over the top layer.
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 brown.
08 - Remove from the oven and let cool for 10 minutes before slicing into wedges and serving.
