For most home cooking, shrimp only need about 1–4 minutes in boiling water, depending mainly on their size and whether they’re raw or frozen.

Quick Scoop

  • Small shrimp: about 30 seconds to 2 minutes once the water returns to a boil, often closer to the low end if they’re truly small.
  • Medium shrimp: about 1–3 minutes in boiling water.
  • Large/jumbo shrimp: about 2–4 minutes; the bigger the shrimp (jumbo or colossal), the closer to 4 minutes.
  • From frozen (not thawed): usually add about 1 extra minute compared with raw thawed shrimp, but many guides still recommend thawing first for best texture.

The real key is to stop as soon as the shrimp turn pink and opaque and form a gentle “C” shape; if they curl tightly into an “O,” they’re overcooked and can turn rubbery.

Simple method: Bring salted water to a rolling boil, add shrimp, cook 1–3 minutes (size‑dependent) just until pink and opaque, then transfer them immediately to an ice-water bath to stop the cooking.

Mini timing cheatsheet (boiling)

  • Small (about 41–50 per lb): 30 seconds to 2 minutes.
  • Medium (31–40 per lb): 1–3 minutes.
  • Large (21–30 per lb): about 2–3 minutes.
  • Jumbo/colossal (under 20 per lb): about 3–4 minutes.

If you’re ever in doubt, err on the shorter time, pull one shrimp, cut it open to check that the center is opaque, then adjust by 30–60 seconds as needed.
