In a large skillet over medium heat, brown 1 pound of ground beef, stirring occasionally for about 6-8 minutes until fully cooked. Add 1 small diced onion, sautéing for 4-5 minutes until tender and translucent. Stir in 3 minced garlic cloves, cooking for another minute, then mix in 24 ounces of marinara sauce, 1 cup of crumbled crispy bacon, 1 teaspoon of Italian seasoning, ½ teaspoon of smoked paprika, salt, and pepper to taste. Let simmer for 10 minutes, then set aside.

In a medium saucepan over medium heat, melt 3 tablespoons of unsalted butter, then whisk in 3 tablespoons of all-purpose flour for 1-2 minutes until bubbling. Gradually pour in 2 cups of whole milk while whisking continuously, cooking until the mixture thickens to a creamy consistency, about 5-7 minutes. Stir in 1 cup of grated Parmesan cheese and 2 teaspoons of garlic powder, seasoning with salt and pepper. Remove from heat once well combined.

Preheat your oven to 375°F (190°C). In a greased baking dish, begin layering by spreading a thin layer of the meat sauce across the bottom. Place 4 lasagna noodles (cooked al dente) on top, then drizzle with béchamel sauce and sprinkle with ½ cup of shredded mozzarella cheese and ⅓ cup of shredded cheddar cheese. Repeat this layering process until all ingredients are used, finishing with a final layer of béchamel and a generous topping of cheese.

Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 30 minutes. After this time, carefully remove the foil and bake uncovered for an additional 15 minutes, or until the top is golden and bubbly. Once done, take the Parmesan Garlic Bacon Cheeseburger Lasagna out of the oven, allowing it to rest for 10 minutes before slicing to ensure the layers hold their shape.
