Preheat oven to 375F (190C). Boil lasagna noodles according to package directions, then drain.

In a large skillet, heat olive oil over medium heat. Add garlic and ground beef. Cook until browned. Stir in tomato sauce and simmer for 10 minutes.

In a bowl, mix ricotta cheese, egg, Parmesan cheese, and chopped basil.

Spread a thin layer of meat sauce in a 9x13 inch baking dish. Add a layer of noodles, then ricotta mixture, mozzarella, and meat sauce. Repeat layers.

Cover with foil and bake for 25 minutes. Remove foil and bake an additional 25 minutes until the cheese is melted and bubbly. Let rest before slicing.
