Package sizes for tortellini range between 10-20 ounces, and the amount of tortellini you add here can be dependent on your pan size – I can never fit a full 20, but sometimes I feel like I can fit a little more than 10? Basically… it’s flexible. Grab a package of tortellini and fit what you can in there.
In the photos above, I’m using a 3 quart All Clad sauté pan. If you have doubts about the size of your pan being big enough, I would suggest just sizing up into a Dutch oven or similar so you don’t run out of room!
