Learning how to devein shrimp is a necessary cooking tip for those who love to cook with shrimp. Sometimes this may have been done for you by the retailer where you purchased them but more often, you will need to do the job yourself.
Shrimp don’t actually have veins, since their circulatory system is open. But they do have a long line down their back which looks like a vein, which is a bit unsightly.
There is nothing quite like the look of a plate of grilled shrimp with the back open and the vein removed. Any good restaurant knows that presentation of shrimp means de-veining them prior to serving. This plate would not look any where near as appealing if the dark vein were showing on the shrimp.
Use these tricks to devein shrimp perfectly every time.
There are two “veins.” One is a white vein which is on the underside of the shrimp. It is white because a shrimp has clear blood. There is no real food safety reason to remove this one (I don’t) but you may do so if it bothers you.
The main “vein” is the one which runs along the top of the body. This is the is the alimentary canal, or the “sand vein,” and is where the body wastes such as sand pass through the shrimp. You remove it, partly because it’s unappetizing, but also so you don’t bite down on the sand and grit.
To devein shrimp, just follow these steps:
- Peel the shrimp first and keep them in a bolw of icy water. This keeps them fresh while you work on the other shrimp to remove the vein.
- Use a very sharp paring knife. ( I have also done it with a very sharp pair of kitchen shears. This method works best with the extra large shrimp. If you have small ones, the paring knife is better.)
- Cut a 1/4 inch deep slit down the back of the shrimp. I start at the fattest part of the shrimp and cut towards the tail. You don’t have to go all the way to the end. The vein will be easily seen at this stage.
- Use the tip of your knife to remove the “vein” and then rinse the shrimp in cold water.

I used these shrimp in my new Shrimp Alfredo recipe with broccoli. You can view the recipe here.
