The Italian name for jumbo pasta shells is "conchiglioni" meaning “conch shells.” You could also use tubes of manicotti as well.
What others are saying
Sam Dalton says:
These were pretty good. I've never had stuffed shells like this before, I'm usually a ravioli kind of guy. I liked these though and will make them again.
Laura Griffin says:
These were superb! Slightly labor intensive but worth all of the work! It really reminds me of a dish I would eat at a nice Italian restaurant. Perfect for date nights or weeknights!
Garcia B says:
These stuffed shells were pretty good. The kids weren’t huge fans of the ricotta but I remedies that by adding some extra mozzarella and sauce on top for them.
Erin Hudson says:
I have a serious obsession with pasta so this dish is at the top of my favorites list. To change it up a little bit I added some pulled pan seared chicken into the cheese stuffing before adding to shells. I ended up having to make a second batch because there we no leftovers.
