Seafood Alfredo Stuffed Shells
Amazing combination of two classic dishes. It’s a perfect union between Seafood Alfredo and Stuffed Shells. Pasta shells stuffed with a mix of shrimp, scallops, crab and cheese, baked in Alfredo sauce.

All this cool weather is making me want to make nothing but comfort food every day. These Seafood Alfredo Shells would make a wonderful weekend comfort dinner.
Seafood and Alfredo sauce go together very well (just think shrimp alfredo) so why not try them in the comforting pasta dish like stuffed pasta shells. Classic stuffed shells is a long time family favorite recipe of mine, and like many other favorite classic recipes, I like to make variations.
You can also add a little of your own variation by using different seafood. I recommend sticking to shellfish like lobster, shrimp, and crab but you can also try adding flaked salmon.
Storing and Reheating Recommendation
- Storing: You can store cooled stuffed shells right in the same baking dish. Cover the cooled dish air-tight with food wrap, foil, or a fitted lid and refrigerate. Properly stored, they should last 2-3 days.
- To reheat: be very careful reheating seafood and cream sauce! It’s very easy to scald and overheat it. You can reheat in the microwave, just make to reheat in 30-40 second increments and just until heated through.
- You can also reheat in the oven at 350°F. Reheat just until heather through.

This recipe looks so good, but coming home from the grocery store and trying to get everything prepared, I find myself a little frustrated because these measurements are in ounces and if you aren’t cooking savvy is a little confusing.
even trying to use Google conversions charts it’s difficult and really only gives fluid ounces.
It says to chop the shrimp but not to chop the Scallops….
What I was hoping would be an easily executed has meal us me very confused lol.
Can the seafood shells be prepared ahead and frozen?
Is there any way to pin this recipe for later? Looks so good.
