About this recipe:Make this classic lasagna recipe zestier by using hot Italian sausage or a little milder with regular Italian sausage. Don't be scared off by the long cooking time. The wait is well worth it. It's a great dish to make for a crowd and easy to adjust for varying tastes. The leftovers are even better when reheated the next day.
Bring a large pot of lightly salted water to a boil. Add the lasagna noodles and olive oil; cook until al dente, 8 to 10 minutes; drain.
Cook the minced beef and sausage in a large pot over medium heat; drain. Stir in the mushrooms, garlic salt, oregano, thyme, basil, and tomato sauce. Season with salt and pepper; simmer 30 minutes.
Meanwhile, mix together the ricotta cheese, eggs, and Parmesan cheese in a bowl.
Ladle enough of the meat sauce into a 24cmx 32cm baking dish to cover the bottom in a thin layer. Form a layer atop the sauce with 3 of the lasagna noodles. Spread about 1/4 of the ricotta cheese mixture over the noodles. Sprinkle about 1/3 of the mozzarella cheese over the ricotta cheese mixture and then ladle about 1/3 of the meat sauce over the mozzarella cheese. Repeat layering twice more, topping with the remaining 100g of mozzarella cheese.
Bake in preheated oven 90 minutes. Allow to sit 10 to 15 minutes before serving.
