Low Country Boil Cook Times: Step-by-Step Timing Guide
The whole trick to a great low country boil is timing. Potatoes need a long time, corn and sausage need a little, and shrimp need almost none. Add everything in the right order and it all finishes at the same moment. Get it wrong and you end up with crunchy potatoes and rubbery shrimp. Here’s the timing, step by step.
Low Country Boil Timing at a Glance
Start your timer once the seasoned water is at a full, rolling boil.
| Step | Add | Cook for | Running total |
|---|---|---|---|
| 1 | Small red potatoes (and onions, if using) | 15 to 20 minutes | 15 to 20 min |
| 2 | Smoked sausage and corn | 8 to 10 minutes | 25 to 30 min |
| 3 | Shrimp | 2 to 4 minutes, until pink and curled | about 30 min |
| 4 | Turn off heat, drain and serve | Right away | Done |
These times are for a typical home batch of 6 to 12 people. Bigger pots take longer to come back to a boil after each addition, so they may need a few extra minutes per step.
Step by Step
1. Get the water to a rolling boil (20 to 45 minutes)
This is the step that takes longest, especially for a big outdoor pot. Fill the pot about halfway, add your seasoning, lemons and garlic, cover it, and bring it to a full rolling boil. A large pot on a propane burner can take 30 to 45 minutes; on a kitchen stove, a smaller pot takes about 20.
2. Potatoes first (15 to 20 minutes)
Add the small red potatoes whole. They’re done when a knife slides in with just a little resistance. They’ll keep cooking a bit after this, so don’t wait until they’re completely soft. If you’re adding onions, they go in now too.
3. Sausage and corn (8 to 10 minutes)
Add the sausage chunks and the corn broken into halves. The water will stop boiling for a minute or two; wait for it to come back up, then start counting. This is when the pot really starts to smell like a boil.
4. Shrimp last (2 to 4 minutes)
Add the shrimp and stir gently. Shell-on large shrimp are done in about 2 to 4 minutes, as soon as they turn pink and curl into a loose “C.” A tight “O” means they’ve gone too far. If you’re not sure, pull one out and taste it.
5. Drain and serve immediately
Kill the heat and drain right away. Shrimp keep cooking in hot water, so don’t let the pot sit. Some cooks pour in a bag of ice to stop the cooking and let everything soak in the seasoning for a few minutes; it’s a popular trick for extra flavor.
Common Timing Mistakes
- Adding shrimp too early: the number one mistake. Shrimp need only a few minutes.
- Not waiting for the boil to return: each time you add cold ingredients the water drops below a boil. Count time from when it bubbles again.
- Overcrowding the pot: too much food for the water means it takes forever to recover. Use a bigger pot or cook in two batches.
- Letting it sit in the pot: drain as soon as the shrimp are done.
Adding Crab or Other Extras
Crab legs sold frozen are almost always precooked, so you’re just reheating them. Add them with the shrimp and give them about 4 to 6 minutes (a couple more if they go in frozen). Whole fresh blue crabs need longer, roughly 10 to 15 minutes, so add them with the sausage and corn.
Frequently Asked Questions
How long does a low country boil take from start to finish?
Plan on about an hour: 20 to 45 minutes to bring the water to a boil, then about 30 minutes of cooking. Prep (scrubbing potatoes, shucking corn, cutting sausage) adds another 15 to 20 minutes.
How do I know when the shrimp are done?
They turn pink and opaque and curl into a loose C shape. That usually takes 2 to 4 minutes for large shell-on shrimp once the water is boiling again.
Can I cook the potatoes ahead of time?
Yes. Some hosts parboil the potatoes earlier in the day to save time. Just shorten the potato step to about 5 minutes so they heat through.
