Start by preheating your oven to 375°F (190°C). Cook your lasagna noodles in salted water according to package instructions, then drain and set aside.

In a large skillet over medium heat, cook the chopped onion until soft and translucent. Add the garlic and sauté for another minute. Next, stir in the ground beef, breaking it apart as it browns. Once the meat is fully cooked, drain off any excess fat.

Now, stir in the crumbled bacon, tomato paste, ketchup, mustard, and beef broth. Add the paprika, salt, and pepper. Simmer the mixture for about 10 minutes until it thickens slightly and becomes rich and flavorful. This beef filling mimics the savory, tangy taste of a loaded cheeseburger.

In a medium bowl, combine ricotta cheese, the egg, and half of the grated Parmesan. Stir until smooth—this will be your creamy cheese layer.

Now it’s time to assemble. Start by spreading a small amount of the meat mixture in the bottom of your 9×13-inch baking dish. Place three lasagna noodles over it. Layer with one-third of the ricotta mixture, followed by one-third of the beef mixture, and a sprinkle of shredded cheddar and mozzarella. Repeat the layers two more times, ending with a generous layer of cheese on top, including the remaining Parmesan.

Cover the dish with aluminum foil and bake for 25 minutes. Then remove the foil and bake for another 10-15 minutes until the cheese is bubbly and golden. Let it cool for at least 10 minutes before slicing to help the layers set.
