The shells can be reheated in the slow cooker or in the oven at 350F, covered with foil for 15 minutes to heat through.

The jumbo pasta shells are stuffed with a mix of ricotta, mozzarella, parmesan, spinach and seasonings. Super cheesy and the creaminess sits so well with the rich tomato sauce.

Nutrition Information
My hubby accidentally bought a package of jumbo shells, and we recently acquired a slow cooker. So I found this recipe, and made it the other day. It turned out so delicious! If I had to do it over again, I’d probably slice the spinach; it tended to clog up the works when piping it in. Stuffing the shells was a bit of a pain in the tookus, but this recipe is so good, I’ll simply use manicotti next time.
Thanks for sharing, Alley!
Great recipe, definitely use the piping method to fill the shells however if any of your shells are in the closed tightly position than piping won’t work. Someone else recommended par-boiling the shells, I would only use that method if half of the shells are closed too tightly to pipe. This recipe is definitely a keeper.
Thanks for sharing, Debbie!
If I wanted to add sausage, what amount would you suggest?
A pound is good!
Sorry one more question. I’m running into an issue of finding jumbo shells, would manicotti work just as well?
Yes!
I made this recipe and it was so good! I added a lb of sausage and was luckily able to find the shells. I found it to make more shells than what it called for. I added more sauce and would add more next time, but I like things really saucy. Definitely will make again, it was perfect for the snow day!
Thanks for sharing!
I found the piping to be quick & easy… when you have to feed 8 people I don’t want to have to take extra steps!!! I do deviled eggs the same way. I plan on making this wonderful meal again, thank you Becky!!!
Thanks for stopping by and sharing, Deb!
I was wondering would cream cheese work because I don’t like ricotta cheese?
I don’t see an issue with that subsitution!
Take n par boil shells till barely soft, push the ends shell will open up and you can fill it we with a spoon, saves time. A piping bag to fill shells? get real.
I am sorry to hear you do not like the method on the recipe, definitely modify it to your liking, Joe.
Serving size ??
28 is not evenly divisible by 8 ????
The shells can be cut in half!
