There’s no need to pre-cook shells before you stuff them. Such a pain messing around with hot floppy shells! Just bake in loads of sauce and they’ll cook in the oven. These jumbo shells, called conchiglioni in Italian, are stuffed with spinach and ricotta. Serve with a Mega Italian Salad and garlic bread for the perfect dinner.

Stuffed shells
I don’t know if you’ve ever tried, but stuffing hot cooked pasta shells is a nightmare. Slipper suckers that they are, and they break so easily.
There’s no need to suffer through all that! It’s much easier to stuff raw, uncooked pasta shells and cook them in the oven simply by covering them in a LOT of sauce. It 100% works. It’s the way I’ve been cooking cannelloni/manicotti all my life.
The trick is simply to start with a large volume of watery sauce that the pasta shells cook in. Not dissimilar to cooking pasta in a pot of boiling water, actually. And by the end, that watery sauce reduces down into a lovely thick pasta sauce!


This method of cooking also deals with another pet-peeve of mine: dry pasta shells. No worries about that here, we end up with plenty of tomato sauce for serving!

What you need for stuffed pasta shells
While there’s many stuffing options for pasta shells, the most popular is probably spinach and ricotta and that’s what I’ve gone with today. Sorry for being predictable? 🙂
Jumbo shells (conchiglioni)
Jumbo shells (conchiglioni is the proper Italian name) are more readily available these days in Australian grocery stores (Woolies, Coles, Harris Farms) and the primary reason I went on a stuffed shells bender.


They are a little more expensive than typical pasta shapes – around $5 for a 500g / 1 lb packet. But they go further. You’ll need 250g / 8 oz for this recipe which serves 5 generously, possibly 6. (Let me remind you, I have a rather robust appetite! My serving portions are not skimpy).
The spinach ricotta stuffing
Here’s what you need for the stuffing. Exactly the same combination I use for spinach ricotta cannelloni, spinach ricotta rolls and the fan-favourite spinach ricotta rotolo.
For a meat option, use the beef filling in Beef Cannelloni instead.

Spinach – use frozen for convenience (thaw, remove excess water before using), or fresh if you’ve got an abundance of it
Ricotta – be sure to use a food quality full fat, creamy one. Tip for Australians: avoid Perfect Italiano tub in the fridge aisle of major supermarkets. It’s quite powdery and unpleasant. My favourite is Paesanella which is sold at Harris Farms and over the deli counter at large supermarkets.
Shredded cheese – A flavoured one is best, like cheddar, tasty, gruyere. Save the mozzarella for the topping (which melts well but doesn’t have that much flavour).
Parmesan – don’t skip this! It adds extra savouriness and seasoning to the filling. Just store bought finely shredded or grated is fine, or grate your own.
Garlic – because it makes everything better
Egg – for binding.
Nutmeg – optional, but it’s a lovely touch. I use it in almost all my spinach ricotta fillings.
Salt and pepper
The sauce
I find this method of cooking stuffed shells from raw works best with a smooth pasta sauce rather than one with lumps of crushed or diced tomatoes. The shells cook more evenly and when it finishes baking, you’re left with a lovely smooth pasta sauce.

Tomato passata – Pureed, strained plain tomatoes, sometimes labelled “tomato puree” in the US (here’s a photo of Mutti tomato passata sold at Walmart). Readily available in Australian supermarkets nowadays, alongside pasta sauces. Excellent for making smooth sauces rather than simmering for ages to breakdown crushed or diced tomato. More on tomato passata here.
Substitutes – US Hunt’s tomato sauce is a perfect alternative. Otherwise, use crushed canned tomato then puree (like I do for cannelloni/,manicotti).
Eschalots –Also known as French onions, and called “shallots” in the US. They look like baby onions, but have purple-skinned flesh, are finer and sweeter. Not to be confused with what some people in Australia call “shallots” ie the long green onions.
I like using eshalots rather than onions because they are finer so they almost disappear into the sauce so you get a lovely smooth sauce. However, you can substitute with a small onion.
Herbs and spices – Fresh garlic, bay leaf, dried thyme and dried oregano.
Tomato paste – To intensify the tomato flavour and thicken the sauce slightly.
White wine – Adds depth of flavour / complexity into the sauce in a way only wine can! It’s only 1/3 of a cup and we simmer to cook out the alcohol. Substitute with more stock, or just skip it.
Vegetable stock – We need a whole litre / quart (4 cups) because we’re making a LOT of VERY watery sauce here! Just watch the video and you’ll see how it all gets absorbed by the pasta shells, leaving behind a lovely thickened pasta sauce for serving.
Sugar – Just a smidge, to take the sour edge off the tomato paste we’re using (tomato paste is sour!).
How to make stuffed shells
It’s actually extremely straight forward and the recipe has a nice flow to it: make the sauce first, then while it’s simmering, stuff the shells. Then assemble and bake!
How to make sauce for stuffed shells

Sauté aromatics – Cook the garlic and eschalots with the herbs in a large saucepan or small pot.
Tomato paste and wine – Cook off the tomato paste for 1 minute (this takes the raw sour edge off and deepens the flavour) then add the wine and simmer rapidly on high heat until it’s mostly evaporated.
Simmer 20 minutes – Add the remaining ingredients then simmer on low for 20 minutes with the lid off.
Watery sauce! The sauce will be VERY watery and there will be loads. Have faith! You need it all – the shells absorb most of that liquid. Keep the sauce hot – we want to use it hot.
Stuffing & bake

Stuffing – Mix the spinach ricotta stuffing ingredients together.
Stuff the raw uncooked shells. I find it easiest to use a small offset spatula (like a butter knife with a bend in it, super useful kitchen tool). Else a knife, spoon – whatever you find makes it easiest for you.
Assemble – Pour the hot sauce into a 23 x 33cm / 9 x 13″ baking dish. Then gently place the pasta shells in. They will be mostly submerged, some might semi-float. But you want most if not all of the pasta submerged under liquid so it cooks evenly (a bit poking above is fine as it will steam-cook).
Bake 70 min covered – Cover the dish with a baking tray (or foil) and bake for 70 minutes. Yes, really, it will take that long!
Why a baking tray? Easy way to cover the baking dish, no waste, no burning yourself, and it lets a little bit of steam escape to help the sauce reduce just the right amount.
15 min bake, cheesed – Remove the baking dish from the oven. Sprinkle with cheese then bake for a further 15 minutes until bubbly and golden.
Serve! Scoop and serve. Marvel at how the shells are perfectly al dente and how there’s so much lovely sauce to serve it with!


Serve with a quick rocket balsamic salad (that’s arugula, to those of you in the States!) or if you’re out to impress, a Mega Italian Salad (it lives up to its name). Add a side of garlic bread and tiramisu to finish, and that’s pretty much my idea of a perfect dinner. When am I coming over?? – Nagi x

Wow. He really will eat anything.

Can this be made without eggs and wine? Or is there something I can substitute it with?
I made this tonight but with some variations, including no eggs or wine. For egg replacement I used 1 tablespoon cornstarch mixed with 3 tablespoons of water. I think that worked well for the texture of the filling. Try substituting the amount of wine with stock, or even better some saved pasta water.
thanks for the recipe! made this for my family and they loved it, will br a staple in my kitchen from now
Another hit! Such a fantastic, simple recipe. Yes, it takes time, but the results are delicious. Highly recommend!
Have made several times, always to great success. For tomato sauce, I use San Marzano and reduce the puree that packs the whole tomatoes. I break by hand the whole tomatoes, then use the reduced sauce as the pour-over.
Just made this for the first time and it is definitely worth the time and effort. This is delicious and was perfectly cooked following the provided times.
Anyone know if i pre made and stuffed the shells and baked it day after will it go soggy?
Have made this a couple of times (always amazing) just wondering if anyone has made this ahead of time and if so, to what stage? Cheers
I have made the filling one day ahead and then stuffed the shells and made the sauce a couple of hours before company arrived. Worked perfectly! You could probably also make the sauce a day ahead.
Second time making this and what a hit! 🤗
Adjustments this time – added 250g beef mince after the onion.
Also had too much cheese filling last time so to reduce cost I used a 375g Woolies brand tub ricotta, 2/3 amount of cheeses, and a 300g bag spinach/kale cooked down on the stove then liquid squeezed out (also captured the liquid to use as some of the vege stock!)
Amazing I’m a cake decorator, I used one of my piping bags, cut the end off a bit wider.. viola!! Great for the cannelloni shells too..YW!
Made this today for dinner. It was so delicious and well worth the time/effort. Love your work Nagi
If l could give a 6 l would. I even forgot the nutmeg and kicked myself but at its best was the day after. My hubby didn’t stop raving about it and was annoyed ld frozen the left overs lol. Its for his lunches 🙄
Love love having you in our kitchen
I’ve made this recipe version twice and found the process of stuffing the uncooked pasta so much better than the floppy cooked pasta versions. It looks like a lot of sauce but it cooked down to just the right amount with pasta cooked perfectly. It was raved about at a shared meal tonight and disappeared very quickly. I’m saving this recipe as my go to. The only change I make is adding lemon zest into the ricotta mixture instead of the nutmeg.
Help! I accidentally used beef broth instead of veg broth! Serving to company tonight. Will it taste ok? TX
Great recipe! Can I use a store bought jar of marinara sauce and just water it down with the vegetable broth to save time?
Forgot to star! If there were 6 I would.
This dish is so delicious. Thanks Nagi! Another winner.
Took about 45 minutes, and my sauce was only a 800g can of San Marzano tomtoes (Cento) which I cut with scissors while still in the can, then poured the contents of the can into the backing dish. I added only some salt. For good measure, I had a couple Italian sausages in the freezer, and tossed them into the mix.
I don’t know what recipe you’re cooking mate but it’s not this one 🤨
Delicious Nagi! As always!
The total time on this is wrong… 25 mins plus 1:45 does not equal 1 hr……..
What are the key ingredients and steps involved in making Spinach ricotta stuffed shells according to Nagi’s recipe?
I cannot believe I will never have to struggle with those slippery pre-cooked shells ever again!!!!!! This turned out perfectly, thank you Nagi!
