01 - Preheat oven to 375°F.
02 - In a large skillet over medium heat, cook ground beef and sausage until browned. Drain excess fat. Add onion and garlic; sauté until softened, about 3 minutes. Stir in marinara sauce, basil, 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 Parmesan cheese until well blended.
04 - Scatter half of the mozzarella 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, then half of the meat sauce evenly over the noodles. Repeat with remaining noodles, ricotta mixture, and meat sauce.
06 - Top with the remaining mozzarella and Parmesan cheese.
07 - Cover edges of the crust with foil to prevent overbrowning. Bake for 40 to 45 minutes until bubbly and golden on top.
08 - Let rest for 10 minutes before slicing and serving.
