Who doesn’t love cute little pasta bundles?? These Pesto Stuffed Shells remind me of little baby lasagnas that have yet to grow into their adult form. They have all the same goodies as a spinach lasagna, like ricotta, mozzarella, Italian herbs, and Parmesan, but are rolled into easy-to-portion pasta shells. And to make life easier, I used store-bought pesto for the filling, which takes care of all the seasoning needs in one swoop. So fast, so easy. And these little Pesto Stuffed Shells freeze beautifully, so don’t be afraid of the large batch size. simply let them cool completely after baking, transfer to a freezer safe container, and stash ’em in your freezer for later!
What Should I Serve with Stuffed Shells?
This is such a classic comfort meal that I suggest pairing it with something simple, like Homemade Garlic Bread and a simple side salad of baby greens and Italian Dressing. If you happen to have any leftover vegetables in your fridge (carrots, tomatoes, mushrooms) add those to your side salad for extra vegetable goodness!
How Many Pesto Stuffed Shells Does This Make?
This recipe made about 22 stuffed shells for me, but your distance may vary. I suggest boiling about 25 shells just in case you have extra filling or a couple of them rip during the stuffing process. I used about 2/3 of a 12oz. box of jumbo shells, which gave me 22 individual shells.
Can I Make Stuffed Shells in Advance?
Yes! If you want to assemble the stuffed shells the day before, refrigerate, then bake the next day, that will work just as well. You may need to add a few extra minutes onto the baking time, to account for the dish being chilled when it goes into the oven.
How Do You Freeze Pesto Stuffed Shells
I prefer to freeze my Pesto Stuffed Shells after baking. I divide them into single servings (about two stuffed shells each), chill them completely in the refrigerator first, then transfer to the freezer the next day. I like to use the small square Ziploc containers.

Pesto Stuffed Shells
Servings 5 4 shells eachIngredients
- 1/2 lb. frozen spinach, thawed ($0.85)
- 15 oz. ricotta ($1.99)
- 1 cup shredded mozzarella ($1.00)
- 1/2 cup basil pesto ($0.85)
- 1 large egg ($0.27)
- 8 oz. jumbo pasta shells (about 22-25 shells) ($1.66)
- 24 oz. pasta sauce ($1.19)
Instructions
- Make sure the spinach is completely thawed, then squeeze out as much of the moisture as possible. Add the spinach to a large bowl with the ricotta, mozzarella, pesto, and egg. Stir until the ingredients are well combined, then refrigerate until it’s ready to be used.
- Bring a large pot of water to a boil, then add the jumbo shells. Cook the shells just until they’re tender, making sure not to over cook the pasta. The longer the shells boil, the more likely they are to tear during the stuffing process. Drain the shells in a colander and then rinse briefly with cool water to make them cool enough to handle.
- Preheat the oven to 350ºF. Spread about 1 cup of pasta sauce in the bottom of a large casserole dish.
- One by one, stuff each shell with a couple tablespoons of the cheese, pesto, and spinach mixture. Place the shells in the casserole dish as you stuff them.
- Once the shells are all stuffed, pour the remaining two cups of pasta sauce over top. Bake the shells for about 30 minutes in the preheated oven, or until the sauce is bubbling up around the edges. Serve hot.

How to Make Pesto Stuffed Shells – Step By Step Photos
First prepare the filling for the shells. Make sure your 1/2 lb. frozen spinach is completely thawed, then squeeze out as much of the moisture as possible. Combine the spinach in a bowl with 15oz. ricotta, 1 cup shredded mozzarella, 1 large egg, and 1/2 cup pesto.
Mix those ingredients together until they’re well combined, then refrigerate them until they’re ready to be used.
Bring a large pot of water to a boil, then add about 22-25 jumbo pasta shells (about 8oz.). Boil the shells just until they’re tender, but still sturdy. Over cooking the pasta shells makes them difficult to stuff without ripping. Drain the pasta in a colander and rinse briefly with cool water to make them easy to handle.
Preheat the oven to 350ºF. Spread about 1 cup of pasta sauce in the bottom of a large casserole dish (about 9×13″).
Stuff each pasta shell with about 2 Tbsp of the prepared spinach and pesto cheese filling, then place them in the casserole dish.
Line the shells up with one another so they are fairly closely packed.
Finally, pour the remaining 2 cups of pasta sauce over the shells.
Since the shells are stuffed with cheese, I didn’t feel the need to top them with even more cheese… but that’s just me. ;P
Bake the Pesto Stuffed Shells in the preheated oven for about 30 minutes, or until the sauce is a little bubbly and browned around the edges.
Serve the pesto stuffed shells hot. Pairs beautifully with Homemade Garlic Bread!

Made this for dinner tonight after finding it on Pinterest while looking for some inspiration. I paired it with roasted asparagus and rotisserie chicken…..Delish! Thank you for a wonderful recipe!
Yum!! My family of 5 enjoyed these SOOO much. Thanks for a great recipe! We added a little bit of cottage cheese to the mixture, and used homemade spinach/basil pesto. Will add to our “regular” menu! Thanks!!
Worked out so well, although the process of putting the mix in the shells was a bit awkward (but I will get better at it), slash I may or may not have eaten half a dish to myself!!
Wow! These were so easy and fast! Not to mention yummy!!
If basil pesto isn’t available in your area, you can try to make this fresh parsley pesto. I like it just almost as much, it’s super quick, and very inexpensive!
For those of us who don’t have cheap basil pesto at the store, how do you make it from scratch on a college student budget?
about to dig into these! just waiting for parmesan knots to finish. thanks for the awesome recipe! :)
Making this tonight…Cheese is ridiculous in New York. Still cheaper than going out though.
Ah i’ve never seen shells this size, and even if i found some I’d never be able to get gluten free ones. ah this looks so yummy though!
Oh, and I also used the ziploc bag trick…I do that with manacotti, too. Soooo easy! I highly recommended it versus spooning the mixture in.
Just made this tonight. It was amazing! I’ve made shells multiple times before, but the pesto basil really made the dish! I did not use spinach, but stuck to the recipe every other way. Every plate was clean within minutes. Definitely a keeper!
I have to make this! Looks great and love all the reviews this has received so I know we will all love it! Thanks for posting!
I have made this recipe so many times. I use it when we are having guests over. It is always a big hit. Thanks!
delicious! my boyfriend at about half the pan ( :/ ) adding spinach is a great idea. i want these everyday
Put your cheese mixture into a Ziploc bag, cut the off one of the edges, and squeeze as a pastry chef would to ice a cake. Much less mess.
