Rice Cooking Time Calculator
Written by Thierno Sadou Diallo, formula verified per our methodology • Last checked on 9/5/2026
Count on about 11 minutes of cooking for white or basmati rice, versus about 35 minutes for brown rice, whose intact outer bran layer considerably slows down water penetration.
Explanation
The cooking-time gap between white and brown rice comes down to their structure: white rice has had its bran (the grain's outer layer) and germ removed during milling, which lets water quickly reach the starchy core. Brown rice keeps this fiber-rich layer, which considerably slows water absorption and requires roughly three times longer cooking to reach a tender texture. The times given here are average benchmarks: the rice's quality and freshness, the size of the pot, and the heat level make the result vary by a few minutes, and some sources go up to 40-50 minutes for brown rice depending on these factors — when in doubt, tasting a few minutes before the stated time is up remains the most reliable way to judge doneness. Soaking brown rice for a few hours before cooking, a common practice, can meaningfully reduce this cooking time by getting water absorption started ahead of time. To find the right amount of water to use for a given type of rice, see our rice water ratio calculator; to scale a recipe's proportions to a different number of diners, our recipe portions calculator.
Example: brown rice
Inputs
Rice type: brown rice.
Calculation
Brown rice takes about 35 minutes to cook, versus 11 minutes for white rice, due to its intact outer layer that slows down water absorption.
Result
Cook this brown rice for about 35 minutes.
Frequently asked questions
Does pre-soaking really reduce brown rice cooking time?
Yes, noticeably: soaking brown rice for a few hours before cooking lets water start penetrating the grain's outer layer before cooking even begins, which shortens the time needed on the stove by that much.
Why do some sources list brown rice cooking time as up to 50 minutes?
Because brown rice cooking time varies noticeably by variety, freshness, and the cooking method used (boiling, absorption, rice cooker). The 30-to-40-minute range covers most common cases, but a particularly old batch of brown rice or a specific variety can legitimately need more time.
Does this cooking time change with the amount of rice being cooked?
No, contrary to a common belief: absorption-method rice cooking time depends on how long it takes for water to penetrate each grain, not on the total amount of rice in the pot. A larger quantity simply needs a bigger pot and more water, in the same proportions, but essentially the same cooking time.
