2. Begin by preheating the oven to 375 degrees F.
3. Cook the ground beef in a skillet over medium heat until it's no longer pink.
4. Spread a thin layer of tomato sauce on the bottom of a 9x13-inch baking dish.
5. Arrange a layer of uncooked lasagna noodles over the sauce and cover with a layer of ricotta cheese mixed with some of the mozzarella cheese.
6. Spread a layer of tomato sauce over the cheese and add another layer of noodles.
7. Cover the noodles with the remaining mozzarella and Parmesan cheese.
8. Top with the remaining tomato sauce and sprinkle some Parmesan cheese over the top.
9. Cover the dish with aluminum foil and bake in preheated oven for 25 minutes.
