  • Jumbo Pasta Shells: Keep an eye on the pasta shells so they don’t overcook. After boiling, set them upside down on a baking sheet to dry.
  • Marinara Sauce: Use your favorite, store-bought or homemade! Or try pesto, Alfredo sauce, or another tomato sauce.
  • Wrap the baking dish tightly in foil for the start of baking, if you don’t, your pasta is likely to burn on the top.
  • Store any leftover shells in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave until warmed through.

How can I add meat to this recipe?

Yes! If you prefer a little meat with your pasta, a ground protein like chicken, beef or turkey will work well. Brown it in a skillet first before mixing with the other filling ingredients.

What can I use instead of ricotta cheese?

Cottage cheese is a great replacement for ricotta as it has a similar texture. Goat cheese would also work great and will have a tangier flavor.

Can I use pesto instead?

Yes! Use your favorite pesto, Alfredo, or tomato sauce for this stuffed shells recipe.
