Pasta shells packed with creamy ricotta and wilted spinach, nestled into a garlicky tomato sauce and blanketed under mozzarella that melts into a golden, lacy crust. Every shell is a little package — pull one out and it comes with sauce clinging to the outside and a cloud of filling inside. The kind of baked pasta that makes people quiet at the table because they're too busy eating.

Method
Thaw the spinach and squeeze out as much moisture as humanly possible — we don't want watery shells, we're scientists here. Lay it in a kitchen towel and wring it out.
Pour in the tomato sauce, give it a stir, and let it simmer gently while you prep the shells. Low and slow builds flavor.
Drain the shells and lay them out on a sheet pan so they don't stick together. Let them cool just enough to handle.
Pour half the tomato sauce into the bottom of a 9x13 baking dish. Spread it around like you're tucking the shells into a little sauce bed.
Pour the remaining sauce over the shells, then top with a good handful of mozzarella — we want that golden, bubbly blanket.
Peel off the foil, give it another 10 to 15 minutes until the cheese is golden and bubbling like a Sunday kitchen.

Dutch OvenSafety & Storage
High Risk Population
Eggs used in the ricotta filling present a food safety risk for vulnerable populations including young children, elderly, pregnant individuals, and immunocompromised persons. Ensure eggs are fully cooked during baking.
Cooking Temperature
Pasta shells must be cooked to al dente initially then baked at 375°F for at least 25 minutes covered plus 10-15 minutes uncovered to ensure the filling reaches safe internal temperature and cheese melts properly.
Cross Contamination
Thoroughly wash hands after handling raw eggs and before touching other ingredients. Use separate utensils and surfaces for raw pasta and ready-to-eat components like cheese and sauce.
Storage
Refrigerate leftover stuffed shells within 2 hours of cooking. Store in airtight containers at 40°F or below. Consume within 3-4 days or freeze for up to 2 months.
Handling
When squeezing moisture from thawed spinach, use clean kitchen towels and wash hands thoroughly before proceeding to mix the filling to prevent bacterial transfer.
Pro Tips
Technique
The biggest mistake people make with spinach stuffed shells is not drying the spinach enough. Really wring it out in a kitchen towel until it's almost dry — that extra moisture will make your shells watery and nobody wants that.
Substitution
If you want to add some protein, mix in a half pound of cooked Italian sausage or some crumbled pancetta into the ricotta filling. It takes this dish from great to absolutely legendary.
Make Ahead
You can assemble these shells the night before, cover them tightly, and pop them in the fridge. The next day, just add an extra 10 minutes to your bake time and you've got a no-fuss dinner that tastes like you slaved all day.
From the chef
There's something about stuffed shells that just screams Sunday dinner at my house. Maybe it's the way the red sauce bubbles up between each shell, or how the ricotta filling comes together like a little package of comfort waiting to be unraveled. This is the kind of dish that brings everyone to the table without a fight.
