How Long to Boil Chicken Breast (Times by Size)

A boneless, skinless chicken breast takes roughly 12 to 15 minutes in barely-simmering water, timed from the moment the water comes up to temperature. A thick one runs closer to 18, a bone-in breast 25 to 30, and one straight from the freezer needs about half again as long. But every one of those numbers is an estimate, and the only figure that actually decides it is 165°F in the thickest part.

The other thing worth knowing before you start: do not boil it. A rolling boil is what makes poached chicken stringy and dry, and it is the reason this method has a bad reputation.

The temperature that ends the argument

FoodSafety.gov’s safe minimum internal temperature chart gives one number for all poultry — “165°F (74°C)” — and it applies to “whole bird, breasts, legs, thighs, wings, ground poultry, giblets, sausage” alike. No rest time is required for poultry, unlike whole cuts of beef and pork.

So the times below are for planning your evening. The thermometer is what tells you dinner is ready. A cheap instant-read digital thermometer — mine is a TP19H — pays for itself the first time it stops you cooking a breast for five extra “just in case” minutes.

Poke the thickest part, not the tapered end, and keep the probe away from the pan bottom.

Timing chart

Times are measured from when the water reaches a bare simmer, with the chicken fully submerged in a pan wide enough that the pieces are not stacked.

Cut	Approximate time	Notes
Boneless breast, thin (about 6 oz)	10-12 min	Check early
Boneless breast, average (7-8 oz)	12-15 min	The standard case
Boneless breast, thick (10 oz+)	16-20 min	Or butterfly it and halve the time
Boneless breast, frozen	18-25 min	Safe, just slower
Bone-in, skin-on breast	25-30 min	Bone slows the heat
Boneless thighs	15-20 min	Very forgiving
Chicken tenders	8-10 min	Easy to overshoot
Whole chicken (3-4 lb)	60-90 min	For stock and shredded meat

Two adjustments that change these more than anything else: pieces of wildly different sizes cook at wildly different rates, so pull the small ones out early rather than cooking to the biggest; and a crowded pan drops the water temperature and adds several minutes.

The method, in six steps

1. Start in cold water. Lay the breasts flat in a wide pan and cover with about an inch of cold water. Starting cold means the outside and the inside come up together.
2. Season the water properly. A tablespoon of salt, a halved onion, a couple of garlic cloves, a bay leaf, some peppercorns. Unseasoned water gives you unseasoned chicken and this is where the flavour comes from.
3. Bring it to a boil, then immediately drop it back. You want the surface barely moving — the occasional bubble, not a churn. Around 180-190°F if you are measuring.
4. Cover and set a timer for the low end of the range in the chart.
5. Check with the thermometer at the thickest point. 165°F and it is done.
6. Rest it in the liquid for five minutes off the heat before slicing or shredding. This is the step most people skip and it is what keeps the meat juicy.

Save the poaching liquid. It is light chicken broth and it is better than anything in a carton — strain it and use it for rice, soup or a pan sauce.

Why a rolling boil ruins it

Chicken breast is very lean, and its muscle fibres contract and squeeze out water fast above about 175°F. A rolling boil holds the outside of the breast at 212°F for the whole cook, so by the time the middle reaches 165°F the outer half has already wrung itself dry and gone stringy.

A bare simmer keeps that gradient small. The difference between poached chicken that shreds into silky strands and poached chicken that shreds into dry threads is almost entirely about how hard the water was moving.

If the pan starts to gallop, take the lid half off. That alone usually drops it back.

Shredding it, and what to make

Shred it while it is warm — cooled poached chicken tears rather than pulls. Two forks work; a stand mixer with the paddle takes about fifteen seconds and is the fastest method I know.

A pan of poached breasts is the start of most of a week:

• Tacos, quesadillas and enchiladas.
• Chicken salad, wraps and sandwiches for lunchboxes.
• Soup — with the poaching liquid you just made.
• Anywhere a recipe assumes a shop-bought bird, which is what our dinners from one rotisserie chicken round up. Poaching is the cheaper way to get there.

If you want the chicken and the starch in one pan instead, one-pot chicken and rice skips the poaching step entirely.

Storing and freezing it

FoodSafety.gov’s cold food storage chart gives cooked meat or poultry 3 to 4 days in the fridge and 2 to 6 months in the freezer, and reminds you that food held at a constant 0°F “can be kept indefinitely” — freezer times are “for quality only.” Raw chicken pieces, for comparison, get 1 to 2 days in the fridge and 9 months frozen.

Cool it quickly, freeze it in flat portions with a spoonful of the poaching liquid to stop it drying out, and you have the backbone of a fast dinner. Our post on freezing cooked chicken has the packing detail.

FAQ

How do you know boiled chicken is done without a thermometer?

Cut into the thickest part. The meat should be opaque all the way through with no pink or translucent patches, and the juices should run clear. It works, but it costs you a cut breast and it is less reliable than 165°F on a probe.

Can you boil chicken from frozen?

Yes, and it is safe. Add roughly half again to the time in the chart and do not skip the thermometer, because frozen pieces cook unevenly. Do not attempt it with a whole frozen bird.

Should the water be boiling when the chicken goes in?

No. Start in cold water, bring it up together, then hold it at a bare simmer. Dropping cold chicken into boiling water seizes the outside before the middle has moved.

How long do you boil chicken for shredding?

The same times — 12 to 15 minutes for an average boneless breast. What matters more for shredding is resting it in the liquid for five minutes and pulling it while warm.

Is boiled chicken healthy?

It is about as lean as chicken gets, since no fat is added and some renders out into the liquid. Season the water well so you are not compensating with heavy sauces later.
