Prepare the meat sauce: In a large pot, brown ground beef and Italian sausage over medium-high heat. Drain excess fat. Add chopped onions, garlic, and bell peppers; cook until softened. Stir in tomato paste, crushed tomatoes, tomato sauce, oregano, basil, salt, and pepper. Simmer for at least 30 minutes, stirring occasionally.
Make the béchamel sauce: In a separate saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes, creating a roux. Gradually whisk in warm milk until smooth. Cook, stirring constantly, until the sauce thickens. Remove from heat and stir in grated Parmesan cheese, salt, and nutmeg.
Cook the lasagna noodles: Cook lasagna noodles according to package directions until al dente. Drain and rinse with cold water to prevent sticking.
Assemble the lasagna: Preheat oven to 375°F (190°C). Spread a thin layer of meat sauce in the bottom of a 9x13 inch baking dish. Layer with lasagna noodles, ricotta cheese, mozzarella cheese, and béchamel sauce. Repeat layers until all ingredients are used, ending with a layer of meat sauce, mozzarella, and Parmesan cheese.
Bake the lasagna: Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 20 minutes, or until the cheese is melted and bubbly and the lasagna is heated through.
Rest and serve: Let the lasagna rest for 10-15 minutes before cutting and serving.
Garnish with fresh basil leaves, if desired.
Excellent recipe! The instructions were easy to follow, and the final product was fantastic. Highly recommend this to anyone who enjoys Italian food.
Wow! This lasagna was restaurant quality. The best I have ever had. Highly recommend. Follow the recipe exactly and you will not be disappointed.
This was a great recipe. I loved the combination of beef and sausage. The lasagna was a bit too cheesy for my taste, but overall, a very satisfying meal.
Absolutely delicious! The meat sauce was rich and flavorful, and the béchamel was perfectly creamy. My family devoured it. Definitely making this again!
Best lasagna I've ever made! The slow baking really makes a difference, allowing all the flavors to meld together. A definite keeper!
