Biganos are a predatory species of sea snail that latch onto oysters. I read about them a while back on Rob Walsh’s blog Texas Eats. Rob explains about the little pests, also known as oyster drills, and their impact on Texas oysters. To sum it up: it ain’t good. These little pests bore into oyster shells and extract all the tasty meat, killing the oyster.
While reading the post, I couldn’t help but to wonder – can I eat them? Cause I’m all about garlic butter baked escargot. Many a time I have pondered raising my own escargot, wild caught from the garden. I mean, if you look at some of the photos below, I already own escargot forks. That’s pretty serious snail love.

So I was pleasantly surprised to find out you can eat these little guys. And I was doubly surprised to discover a new Houston market selling Biganos. Louisiana foods on Saturday morning hosts a bycatch fish market. PJ, the fishmonger, and another gentleman, Billy, offer local seafood and rarely eaten bycatch fish. Bycatch meaning the stuff that usually gets thrown out by the fisherman while fishing for more marketable specimens like shrimp.
I visited the market a couple of weeks ago. PJ was super helpful on Bigano cooking tips. He recommended a crawfish style boil with seasonings for an hour and a half. It worked great and the snails came out perfectly tender.
I only picked up two pounds of the snails the first visit. Next time I’ll grab more. Then it’ll be time to experiment with some garlic and butter baked Biganos!
In the meantime, here’s a very rough recipe to get you started boiling your own Bigano snails:
Bigano Snails in a Crawfish Boil
2 pounds of live Bigano snails (but the more the merrier)
Crawfish boil seasoning to taste
Water
Note: PJ recommends storing freshly purchased, live Biganos on top of a moist towel or rag in a container in your fridge. My tip is to use a rag you hate because those little guys smell strongly of the ocean (won’t come out) and the snails release a purple dye (won’t come out).
Prepare the snails by rinsing them thoroughly. Soak them for 30 minutes or so, letting them expel any sand and other fun bodily fluids. Rinse a few times again for good measure.
In a large stock pot, place the snails in side and cover with water with a few additional inches at the top.
Bring to a boil. Add a few tablespoons of crawfish boil seasonings and reduce heat to medium / low. Cook for an hour or more until desired tenderness is achieved.
To eat: first remove the hard thin disc at the foot of the snail. With an small fork, nail, or strong wooden skewer, hook the exposed meat and gently pull it out of the shell.
On top of the snail meat will be a sac of intestines: pinch them off.
The remaining meat is ready to eat. Bon appetit!
