Ragu is a meat-based sauce that includes finely chopped vegetables, and ground meat and is simmered with high-quality crushed tomato as a base. See this post for my recommendations on canned tomatoes. For this recipe, I use my Nonna's tried and true RAGU RECIPE, which we eat weekly with pasta. A certain magic happens as the ground beef and aromatic vegetables slowly cook down tomato sauce in this classic ragu recipe. Your house will smell amazing with this lasagna baking. The homemade ragu sauce, stewed with rich tomatoes, adds the Italian flavor you crave when seeking a quality lasagna recipe. STORING: You can store homemade ragu sauce in an airtight container in the fridge for three days OR freeze it for several months.
