How to Cook Shrimp Without Them Shrinking

Why do shrimp curl up when they’re cooked?

The underside of the shrimp is connected. Next time you have a shrimp in hand, flip it over and look at its underside area. You’ll notice a bunch of small slats that fold into each other where the shrimp’s belly is. These slats make the shrimp curl up tightly as it gets cooked. Some shrimps curl up more than others. Small shrimp are more likely to curl up into themselves than larger shrimp.

How do you prevent shrimp from curling up?

Make small slits on the underside of each shrimp. Flip the shrimp over and make 2 to 3 shallow cuts with a knife on the inside curve of the shrimp. Press the shrimp flat on a cutting board to open them up before you start cooking. The cuts that you make will disconnect the underside of the shrimp, making it less likely to curl up so tightly.

Should you rinse shrimp before cooking it?

Yes, rinse and drain shrimp in a colander. This will remove any loose shell bits or gunk still left on its flesh. Use cool water and rinse your shrimp thoroughly after you clean it. Even if your shrimp is frozen, you should still rinse it off to get rid of any ice crystals from the freezer.
