In a large skillet, brown the ground beef and Italian sausage over medium-high heat. Drain any excess grease.
Add the chopped onion, garlic, and bell pepper to the skillet and cook until softened, about 5 minutes.
Stir in the crushed tomatoes, tomato paste, Italian seasoning, salt, pepper, and sugar. Bring to a simmer and cook for at least 30 minutes, stirring occasionally.
While the sauce simmers, prepare the béchamel sauce. In a saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes to create a roux.
Gradually whisk in the milk until smooth. Bring to a simmer, stirring constantly, until the sauce thickens, about 5-7 minutes. Remove from heat and stir in the nutmeg, salt, and pepper.
Preheat oven to 375°F (190°C). Spread a thin layer of meat sauce in the bottom of a 9x13 inch baking dish.
Layer lasagna noodles, meat sauce, béchamel sauce, mozzarella cheese, and Parmesan cheese. Repeat layers until all ingredients are used, ending with a layer of cheese.
Cover the dish with foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbly.
Let the lasagna rest for 10-15 minutes before slicing and serving.
This lasagna is amazing! The flavors are well-balanced, and the texture is perfect. It's a great recipe for a special occasion.
This lasagna was a hit! I especially loved the balance of flavors. The instructions were clear, although the cooking time seemed a bit longer than expected.
This lasagna is perfect! I've made it several times, and it always turns out great. The recipe is easy to follow.
Best lasagna recipe I've tried. The meat sauce was rich and flavorful, and the layers were perfect. Highly recommend it!
It was okay. I found the meat sauce a bit dry. Next time, I'll try adding a little more liquid.
