01 - Preheat your oven to 375°F.
02 - In a large skillet over medium heat, cook the ground beef and Italian sausage until browned throughout. Drain off 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 the mixture for 5 minutes, then remove from heat and set aside.
03 - In a medium bowl, combine the 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 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 layering with the remaining noodles, cheese mixture, and meat sauce.
06 - Top the assembled pie with the remaining shredded mozzarella and the rest of the grated Parmesan cheese.
07 - Cover the edges of the pie crust with aluminum foil to prevent overbrowning. Bake for 40–45 minutes, until the top is bubbly and golden brown.
08 - Remove from the oven and let the lasagna pie cool for 10 minutes before slicing into wedges and serving.
