1. Heat a little oil. Sauté minced meat until it changes color. Add a bit of garlic and onion, mix well and cook until wilted. Then, add the mushroom, stir again. Add tomato sauce from chopped tomatoes and water. Cook until bursting before adding sugar, salt, pepper, oregano, and basil. Stir well and sample to make sure you have the correct taste. Cook on low heat until the tomatoes are crushed. Lift and set aside.
2. Next, let’s make the sauce! Melt the butter in the pan, add flour then mix well. Pour in liquid milk, stir until evenly mixed and not crushed. Add grated cheese and pepper. Then, mix well and cook on low heat until the cheese melts and thickens. Lift and set aside.
3. Prepare a heat-resistant container or a sheet of aluminum foil or a baking sheet. Arrange 2 tablespoons of meat sauce to cover the bottom of the pan. Put a piece of lasagna skin then add to the top surface 2 tablespoons of cheese sauce and 2 tablespoons of meat sauce.
4. Arrange again with lasagna skin. Repeat the steps until you run out of mixture. Sprinkle the mozzarella cheese and parsley on the top surface. Bake for 30-40 minutes or until cooked.
Lift, serve and enjoy!
