Italian Sausage Stuffed Shells Recipe
I used to make this meal with manicotti, but I have found that the shells are easier to stuff. Manicotti will absolutely work if that’s what you have on hand. We have also used ground beef in place of the Italian sausage and it was still really yummy.
The trick with this recipe is to cook the shells and let them cool slightly on a cookie sheet without touch each other. That way, they won’t stick together and rip when you’re trying to stuff them with Italian sausage and cheese.
This recipe for Italian sausage stuffed shells is also freezer friendly. Read how to freeze casseroles here.

What to serve with Italian sausage stuffed shells?
We love serving Italian food with a simple green salad and some type of bread. I recommend this cheesy garlic bread recipe or these parmesan garlic crisps. Plain French Bread is yummy with this dish, too!
