It takes three minutes to steam 1 cup of baby carrots in the microwave. Put the baby carrots in a lidded microwave-safe dish, add 2 tablespoons of water, put the lid on the dish and cook at 100 percent power for three minutes. Allow the carrots to cool in the covered dish for five minutes after cooking.
Your microwave is not your only option for steaming baby carrots. If you are using a steamer to cook a pound of baby carrots, it takes about eight to 10 minutes for them to cook. If you prefer to steam the baby carrots in a pan, boil them in a half-inch of salted water until the carrots are tender and the water has evaporated, which takes about five minutes, although they are more tender if you let them cook longer.
