Preparation:

Step 1: Prepare the Meat Sauce

1. In a large skillet over medium heat, cook the ground beef until browned and crumbled.
2. Add the chopped onion and cook until softened, about 5 minutes.
3. Stir in the garlic and cook for 1 minute until fragrant.
4. Add the crumbled bacon, marinara sauce, Italian seasoning, and smoked paprika. Season with salt and pepper to taste. Let it simmer for 10 minutes.

Step 2: Make the Parmesan Garlic Béchamel

1. In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute to form a roux.
2. Gradually whisk in the milk, ensuring there are no lumps.
3. Cook the mixture until it thickens slightly, about 5 minutes.
4. Stir in the Parmesan cheese, garlic powder, and season with salt and pepper. Remove from heat and set aside.

Step 3: Cook the Lasagna Noodles

1. Bring a large pot of salted water to a boil.
2. Cook the lasagna noodles according to package instructions. Drain and lay flat on a baking sheet to prevent sticking.

Step 4: Assemble the Lasagna

1. Preheat your oven to 375°F (190°C).
2. Spread a thin layer of meat sauce at the bottom of a 9×13-inch baking dish.
3. Add a layer of lasagna noodles, followed by a layer of meat sauce, a drizzle of béchamel, and a sprinkle of mozzarella and cheddar cheese.
4. Repeat the layers until all ingredients are used, ending with a generous layer of cheese on top. Sprinkle with grated Parmesan cheese.

Step 5: Bake the Lasagna

1. Cover the baking dish with aluminum foil and bake for 25 minutes.
2. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
3. Let the lasagna rest for 10 minutes before slicing and serving.
