This recipe makes enough filling for 21-24 shells (depending on whether you use mozzarella); but a 12-oz box contains 36-40 shells. Some shells may tear, so you may wish to cook more than 24 shells, but you don't need to cook the whole box.
If you do want to make use of all the shells in a 12-oz. box, multiply the ingredients by 1.5x. You will likely need an additional casserole pan to fit all the shells.
Cooking the shells al dente reduces tearing, and the shells will soften further in the oven. You don't need to cook the shells for the time listed on the box.
Store and reheat: Cover casserole dish with plastic wrap or place shells in an airtight container and refrigerate for up to 3-5 days. Reheat in the oven at 350°F (180°C) for 15 minutes.
