Cook the Beef: In a large skillet over medium heat, cook the ground beef until browned. Add diced onion and minced garlic, stirring occasionally. Cook for 3-4 more minutes until the onion softens. Drain excess fat.
Make the Meat Sauce: Stir in marinara sauce, ketchup, Worcestershire sauce, salt, black pepper, paprika, garlic powder, and Italian seasoning. Simmer for 5 minutes to blend the flavors.
Prepare the Cheese Mixture: In a bowl, whisk together ricotta cheese, egg, Parmesan, and half of the parsley until smooth.
Assemble the Lasagna: Preheat oven to 375°F (190°C) and grease a 9x13-inch baking dish. Spread a thin layer of meat sauce on the bottom. Layer cooked lasagna noodles, ricotta mixture, and more meat sauce. Sprinkle cheddar and mozzarella. Repeat layers, finishing with cheese and crumbled turkey bacon on top.
Bake: Cover with foil and bake for 30 minutes. Remove foil and bake for 10 more minutes until golden and bubbly.
Rest and Serve: Let lasagna rest for 10 minutes before slicing. Garnish with remaining parsley and serve warm.
