Costco’s $11.99/lb Seafood Boil Is the Ultimate Summer Backyard Party Shortcut
Costco has a way of dropping products that stop people mid-aisle, and the Lusamerica Seafood Boil is one of them. For $11.99/lb, you’re getting wild Dungeness crab, shrimp, mussels, clams, red potatoes, corn, and a spice packet — pre-cooked and ready to eat in just 6 minutes.
Yes, six minutes. No giant pot, no boiling water, no two-hour prep. Just heat and eat.
What’s Actually in the Bag?
This isn’t a shellfish-forward trick where you get one sad crab leg and a lot of potatoes. The Lusamerica mix is legitimately loaded:
- Wild Dungeness Crab — the headliner, and a premium one at that
- Shrimp, Mussels, and Clams — a proper seafood boil spread
- Red Potatoes and Corn — the classic low-country filler that soaks up all the spice
- Spice Packet — so the seasoning work is already done for you
Dungeness crab alone typically runs $10–$15/lb at the seafood counter when you can even find it. Getting it bundled with three other proteins plus sides at $11.99/lb is legitimately strong value — especially heading into peak summer entertaining season.
Who Should Grab This?
This deal is tailor-made for a few specific households:
- Families hosting summer cookouts who want an impressive spread without a full day of cooking
- Southern families who love a seafood boil tradition but don’t always have time for the full ritual
- Apartment dwellers with no outdoor burner setup — microwave or stovetop reheat handles this
- Date night or small gatherings where you want to look like you really cooked
If you’ve ever priced out a DIY seafood boil at the fish counter — buying crab, shrimp, mussels, and clams separately — you know how fast $60–$80 disappears before you even touch the Old Bay. This is a genuine shortcut.
The Honest Caveats
A few things worth knowing before you load up your cart:
- Pre-cooked means texture trade-offs. It won’t have the same shell-cracking, briny freshness of a live crab boil. The shellfish will be softer than from-scratch.
- Spice level is moderate. If your crew likes serious heat, have your own seasonings ready to punch it up.
- It’s sold by the pound, so a feast for four adults will likely run you 4–6 lbs — budget $48–$72 total. Still cheaper than a restaurant seafood boil for a family.
- Availability varies by warehouse. Costco rotates seasonal items, so if you see it, don’t wait.
Set the Scene Right
Half the fun of a seafood boil is the experience — newspaper on the table, everyone digging in together. A few things make this even better:

Bottom Line
For $11.99/lb, the Costco Lusamerica Seafood Boil delivers a ready-in-6-minutes spread that would cost twice as much to assemble from scratch — and far more to order at a restaurant. It’s not a replacement for a proper backyard boil, but as a shortcut to a legitimately impressive summer meal, it earns its spot in the cart.
