How Many Stuffed Shells Per Person Do You Need?

An average serving size is 2-3 shells per person, assuming you’re serving garlic bread, salad, or other food alongside your pasta. Heartier appetites might eat more. This recipe calls for 16 shells, so will serve 5-6 people, but plan for more if you want this to be the only item you serve.

Tips and Recipe Notes

  • To keep shells from sticking together and breaking, add a small amount of olive oil to the boiling water and use plenty of water to cook the shells. Carefully remove the shells using a slotted spoon and be sure all the water drips from inside the shell. Allow shells to drain and cool on paper towels or in a colander. 
  • This recipe can be put together the night before and baked fresh the next day. Cover tightly and store in the refrigerator until ready to bake.
  • To avoid your dish from becoming watery, make sure you don’t have too much water in your ricotta or your spinach. Spread your ricotta and spinach on paper towels and allow it to soak up any excess water before making your filling.

Ingredient Substitutions and Variations

  • If you prefer a meaty version, add cooked ground beef or Italian sausage to the marinara sauce.
  • You may use frozen spinach in place of fresh spinach. Completely thaw the frozen spinach before adding it to your cheese mixture. If it’s wet, dry it with paper towels.
  • If you can’t find jumbo shell pasta, try using manicotti. Fill the manicotti tubes with the cheesy mix.
  • Parmesan cheese can be replaced by pecorino.
  • Add some feta for a salty kick to your filling.

How Do I Store Leftover Stuffed Shells with Cheese and Spinach?

Left-over shells can be stored in the refrigerator for 3-5 days in an air-tight container.

Can Stuffed Shells Be Left Out Overnight?

I wouldn’t recommend eating these (or any) stuffed shells if they’ve been left out overnight. Bacteria grows rapidly at room temperature, and eating these after they’ve been out for more than two hours can make you sick.

Can I Freeze Spinach and Ricotta Stuffed Shells?

This recipe can be baked, then frozen to be served later. Allow the casserole to cool to room temperature. To freeze, tightly cover the pan with plastic wrap, then with foil and fully seal the edges. Place in the freezer for up to 3 months.
