Creamy Seafood Stuffed Shells That’ll Make You Cancel Your Restaurant Reservations
I used to think stuffed shells were a relic of 90s potlucks. Then I got bored, made a bet with my cousin, and accidentally created a recipe that broke our family group chat. This isn’t your nonna’s pasta bake.
This is a flavor explosion that turns a simple pasta shell into a vessel for luxurious, briny, creamy seafood goodness. My creamy seafood stuffed shells are the main character of your next dinner party. They look fancy but are secretly low-effort.
Forget dry, boring fillings. We’re making magic.
It’s the texture, honestly. The tender jumbo pasta shell gives way to a rich, creamy filling that’s packed with sweet, succulent crab and shrimp.
The sauce isn’t just a topping; it’s a cheesy, garlicky blanket that seeps into every nook. Remember that one restaurant dish you keep thinking about? This is the homemade version that somehow tops it.
It feels decadent without requiring a finance degree to afford. Who knew a humble pasta shape could host such a luxurious party?

Step-by-Step Instructions
- Cook your pasta shells. Boil them in well-salted water until al dente. They should still have a slight bite.Drain and rinse with cool water to stop the cooking. This prevents them from turning into a mushy mess later. Lay them out on a baking sheet so they don’t stick together.
- Create the creamy seafood filling.In a large bowl, combine the crab, shrimp, cream cheese, ricotta, Parmesan, half the mozzarella, garlic, and Old Bay. Mix gently but thoroughly. You want everything well-integrated without pulverizing the beautiful crab lumps.Taste it. It should already be delicious.
- Stuff those shells. This is the therapeutic part.Using a spoon or your hands, generously fill each pasta shell with the seafood mixture. Don’t be shy. Overstuff them.Place them seam-side up in a 9×13 baking dish that you’ve lightly coated with a thin layer of sauce.
- Whip up the simple sauce. In a separate bowl, mix the marinara sauce with the heavy cream. This creates a rosé-style sauce that’s rich and tangy.Pour this evenly over all the stuffed shells in the dish, making sure to get into the corners.
- Top and bake to perfection. Sprinkle the remaining mozzarella and a little extra Parmesan over the top. Bake at 375°F (190°C) for 25-30 minutes, until the cheese is golden and bubbly and the filling is hot.Let it rest for 5-10 minutes before serving. This step is crucial for the perfect creamy seafood stuffed shells consistency.

FAQs
Can I freeze this?
Absolutely. This is one of the best freezer meals. Assemble the dish completely but do not bake it. Wrap it tightly and freeze. Bake from frozen, adding about 15–20 extra minutes to the cooking time.
What’s the best substitute for crab?
If you’re not a crab person, chopped scallops are a fantastic substitute. They have a similar sweet, delicate flavor and texture that works beautifully in the creamy filling for these shells.
How long does it stay fresh?
When stored properly in the refrigerator, your creamy seafood stuffed shells will be at their best for up to 3 days. The pasta may soften a bit more, but the flavor will still be amazing.
Is this kid-friendly?
It can be! My trick is to chop the shrimp very finely and use a mild marinara sauce. The creamy, cheesy flavor is usually a big hit, and you can call them “seafood boats” for fun.
Can I prep it ahead of time?
Yes, and I highly recommend it for stress-free entertaining. You can assemble the entire dish, cover it, and keep it in the fridge for up to 24 hours before you need to bake it. FYI, you might need to add a few extra minutes to the bake time since it will be going in cold.
