If you’re looking for a lighter – and vegetarian – version of stuffed shells, you’ve come to the right place. Our recipe is also a change from the traditional meat stuffed and tomato topped version, perfect for warmer weather.

One question everyone asks is whether the pasta should be partially cooked before stuffing. After all, it’s getting a second cooking in the oven. Not to worry. Shells (Conchiglie) are made with durum, a hard wheat that keeps the pasta firm after boiling and throughout baking.

This recipe is very forgiving. You can use more or less of any of the ingredients. Just make sure you keep the egg to bind the filling.


  • Manicotti, large tube-like pasta, can be used in place of jumbo shells. Like shell pasta, it’s meant to be stuffed and won’t become mushy from baking.
  • You can make this a day ahead or keep in the freezer for up to 3 months. Just don’t do the final baking. From the fridge, you may need a few more minutes to bake. From the freezer, no need to defrost but allow about an hour for baking.
