Recipe Tips
For a more authentic lasagna flavor, layer the additions of ricotta. After the pasta is halfway cooked, add half the ricotta in dollops and stir gently. Then top with remaining ricotta before covering. This creates pockets of cheese throughout the dish rather than just on top. If your sauce becomes too thick before the pasta is fully cooked, add water in small increments to reach desired consistency.
