Beat in ricotta cheese. Add eggs one at a time, beating just until combined and scraping down sides of bowl after each addition. Pour into crust-lined pan.
Bake at 325°F. for 1 hour 10 minutes to 1 hour 20 minutes or until sides of cheesecake are set and puffed but center still moves slightly when pan is tapped. Cool cheesecake in pan on wire rack for 1 hour. Cover; refrigerate at least 3 hours or overnight before serving.
