In this classic Italian stuffed shells recipe, there’s no need to parboil the pasta—just stuff, bake, and enjoy!

Spoon scooping cheesy stuffed shells from a baking dish.

When I think of classic Italian stuffed shells, I think of cozy Sunday night dinners around the table with family, with both adults and kids eagerly diving into their favorite comfort food. This recipe, adapted from Big Flavors from Italian America by America’s Test Kitchen, fits that bill perfectly. The recipe is fairly simple to make because there’s no need to parboil the shells before stuffing them. Instead, the shells are smothered in a thin tomato sauce prior to baking, ensuring the pasta cooks through. The filling is loaded with flavor, thanks to a blend of creamy ricotta, gooey fontina, and salty Pecorino Romano cheeses, as well as garlic, basil, and oregano. Finally, to make the dish even more irresistible, a generous sprinkle of fontina cheese over the shells creates a rich, cheesy topping. Even without any meat, this dish is as satisfying as the heartiest lasagna.

To stuff the shells, disposable pastry bags come in handy (and you can use them for decorating cakes and cookies or filling deviled eggs, too). However, if you don’t have them, a ziplock bag with a snipped corner does the job well.

“Well, this is one of the best Italian-style meals that I’ve ever made. It cooked perfectly and it tasted fantastic! Raves all around for this one.”

What You’ll Need To Make Stuffed Shells

stuffed shells ingredients
  • Extra-Virgin Olive Oil: Used to sauté the onion and garlic, it creates a rich, flavorful base for the sauce.
  • Yellow Onion and Garlic: These aromatics build depth and savory notes, making the sauce aromatic and robust.
  • Crushed Red Pepper Flakes: Add a subtle kick of heat, balancing the richness of the cheese and tomatoes.
  • Crushed Tomatoes: Form the heart of the sauce, providing a thick, velvety texture and fresh tomato flavor.
  • Water: Ensures the sauce simmers to the perfect consistency while maintaining balance.Sugar: Adds a touch of sweetness to offset the tomatoes’ natural acidity.
  • Ricotta, Fontina or Mozzarella, and Pecorino Romano: Combine to create a creamy, melty, and slightly tangy filling for the shells. Make sure to buy whole milk ricotta for a smooth, creamy texture.
  • Eggs: Bind the filling, ensuring it holds its shape and doesn’t ooze out during baking.
  • Cornstarch: Stabilizes the filling while keeping it light and smooth for easy piping.
  • Fresh Basil and Dried Oregano: The herbs infuse both the filling and sauce with bright and earthy notes.
  • Jumbo Pasta Shells: Their sturdy shape holds the rich filling and absorbs the flavorful sauce during baking.

Make-Ahead, Freezing & Storage Instructions

The stuffed shells can be assembled and refrigerated up to 1 day ahead of time, or frozen for up to 3 months. Defrost in the refrigerator for 24 hours, then proceed with the baking instructions in the recipe. You can also freeze leftover stuffed shells; if time allows, thaw before reheating, then cover with foil, and heat in a 325°F (165°C) oven until hot.

  • Hi Jen, I have been making stuffed shells for years. Everyone loves them and asks for them all the time, but I always hated the parboiling step!! I don’t usually look at recipes that I make all the time, but I’m glad I did. Your recipe is excellent, but the elimination of the parboiling step is brilliant and an amazing time saver!!! Thank you. We use many of your recipes, and they are each fantastic. …of course we are always looking at your books too.

  • hi Jenn–
    Happy Holidays – if you wanted to substitute a high quality jar sauce, how many ounces and would you still need the water to cook the shells?
    thanks so much
    Cindy

    • Hi Cynthia, happy holidays to you! I’d recommend a 32-ounce jar of pasta sauce mixed with 2 cups of water. (The tomato sauce is supposed to be on the thin side.) Hope that helps and that you enjoy!

  • I am so excited to try your version of stuffed shells. I know from your past recipes, this will be a hit. I do have a question. I would like to make this two days before I serve it. Would I assemble the dish, and bake before serving, assemble then bake it for half of the amount of time and continue the baking before I serve it or assemble bake and reheat (reheat at what temp & time?) Help!!

  • Made this recipe last night. It was great the night of, but even better as leftovers today. I do have one question….after filling the shells, I had quite a bit of the cheese filling leftover. Is there something I could do with the leftover filling? Can it be frozen?

    • Glad you enjoyed it! I’m surprised you had a lot of filling left over. Did you fill the shells completely? I don’t think the filling would freeze well, but you could just fill more shells and use a smaller dish to bake those.

  • Very tasty! I too had a little trouble finding the jumbo shells but came up with a box eventually.
    Makes a nice side dish to breaded chicken breast or Italian sausage! Fun to fill those shells too!
    Thanks Jen!

  • I got everything for this recipe except the Jumbo Shells. Apparently, there is a shortage of them after asking customer service at my 3rd grocery store. Any ideas for a workaround? Love your 2 cookbooks and am making Chicken & Quinoa burrito bowls for company tonight.

  • Well, this is one of the best Italian-style meals that I’ve ever made. It cooked perfectly and it tasted fantastic! Raves all around for this one.
    I used 1 lb. of finely crumbled sweet Italian sausage, a a primo 32 oz. jar of marinara sauce (along with 2 cups of water) and grated fontina cheese (thanks, Jenn).
    I had read an earlier comment that jumbo shells were becoming hard to find, so that day I went out to buy some and sure enough, they had vanished from the shelves all over town. I had to buy some online. Plenty of other pasta available, though. Go figure.
    Anyway, thanks ATK and Jenn for adapting this recipe for us. I really appreciate it.

  • Thank you Jen, another great recipe. I just had a little problem finding the large shells, but the third store had them. I also had a little mess trying to stuff the shell. Finally I got the assembly going with great success. Thank you for your excellent instructions. I needed them.

  • Hi Jenn, Why do you include cornstarch in the recipe?

    • Hi Carol, It helps prevent the cheese mixture from oozing out of the shells during baking.
