Stuffed shells is a classic dish from Italian-American red sauce joints. Unfortunately, it's pretty easy to mess up. From shells that get too crispy in the oven to a stuffing that's too dry, there are a number of ways that this dish can go from "wow" to "ho-hum." But the recipe below overcomes all of these issues and more.
To start, you'll need a homemade marinara sauce with a rich flavor. Then you combine ricotta, mozzarella, cottage cheese and rich ground beef and stuff the mixture into the shells. Finally, bake the casserole covered until the very end, so that it doesn't dry out.
