A Good Housekeeping report says adjusting a microwave’s power level can help heat some foods more gently and reduce overcooked edges or uneven results. Experts recommend lower power for delicate foods, medium power for many leftovers and high power for foods with plenty of water; exact controls vary by model.
A Good Housekeeping report says adjusting a microwave’s power level, rather than always using its default full-power setting, can help reduce uneven heating and prevent some foods from becoming dry or rubbery. Kitchen experts interviewed by the publication recommend matching the setting to the food, with low power for delicate items, medium power for many leftovers and high power for quick heating or steaming.
Microwaves heat food by emitting energy waves that make water molecules vibrate, generating heat. The power control changes how the microwave delivers energy. According to Steph Chen, founder and CEO of microwave cookware company Anyday, conventional microwaves often cycle on and off at reduced settings. The pauses give heat time to spread through food, rather than continually heating its exterior.
Microwaves with inverter technology work differently: they can supply a lower amount of power continuously, according to Eva Bleyer, a Good Housekeeping Reviews analyst who tests microwaves. The report says either approach can help with more controlled heating, though results depend on the appliance and food.
For many models, users can set a cooking time, press a button labeled Power or Power Level, and select a percentage or number. Bleyer says some microwaves display 10, Full Power or 100% as the default. Controls vary, and automatic programs such as popcorn may not allow users to change power. The report advises checking the manufacturer’s instructions for a specific model.
A gentler setting can protect texture
Changing power matters most when food needs time to heat through without its surface overheating. The report recommends lower settings for foods prone to burning or separating, including chocolate, custards, and dairy- or sugar-based sauces. It also suggests lower power for delicate proteins such as seafood and chicken, and for eggs and grains that can turn tough or cook unevenly. Sauces and similar foods should be stirred frequently; the source advises stirring every 15 seconds for especially delicate mixtures.
For reheating leftovers, Chen recommends medium power, around 50%, to heat more gently and help food retain or regain moisture. The report singles out frozen items and foods that are difficult to stir, such as casseroles, pot pies and burritos. By contrast, high power is suited to heating foods with high water content, including vegetables, soups and sauces, and can bring food to temperature quickly. Covering the dish can limit splatters, but bowls may become very hot; use oven mitts when removing them.

How microwave power is delivered
The report’s central point is that power level is not the same as cooking time: it changes how energy reaches food during the cooking period. On a traditional microwave, a reduced setting may mean full power is delivered intermittently. In an inverter model, power can be reduced steadily. The way a particular appliance behaves depends on its design.
Chen compared defaulting to full power with using high heat for every stovetop task, saying that different foods need different levels of heat. She also said high power works for quickly bringing food to temperature, while medium or low power can offer more control when reheating. These are expert recommendations reported by Good Housekeeping, not guarantees that every recipe or microwave will produce the same result.
“Most people use their microwave on full power all the time, but full power isn’t always the right setting. It’s similar to cooking on the stovetop—you wouldn’t cook everything on high heat.”
— Steph Chen, founder and CEO of Anyday, as quoted by Good Housekeeping
Results depend on the microwave model
The source does not provide controlled test results quantifying how much a lower power setting improves evenness or texture. It also does not specify cooking times for individual dishes, which can vary with microwave wattage, portion size and food composition. The suggested controls may differ by model, and the report says presets may prevent power adjustments. Users should consult their appliance manual and check that food is heated or cooked as needed rather than treating one setting as a universal rule.
Check the controls before reheating
The practical next step is to look for a Power or Power Level control and consult the manufacturer’s instructions if the button sequence is not clear. For a trial, the report’s guidance is to use medium power for leftovers and lower power for foods that need gentle heating, then adjust based on the result. Use high power for quick heating of water-rich foods, cover dishes to reduce splatter, and handle heated containers with oven mitts. The supplied source identifies no planned follow-up announcement or new study.
Key Questions
What does a microwave power setting change?
It changes how the microwave delivers energy during cooking. Traditional models may cycle on and off at lower settings, while inverter models may deliver reduced power continuously, according to the experts quoted by Good Housekeeping.
What power level should I use to reheat leftovers?
The report cites about 50% power as a useful medium setting for many leftovers, especially foods that are difficult to stir. Heating time will depend on the microwave and portion, so check the food as it warms.
When should I use low power?
Experts cited in the report recommend lower power for delicate or easily overcooked foods, including chocolate, custards, some sauces, seafood, eggs and grains. Stir foods such as sauces frequently when appropriate.
How do I change the microwave power level?
On many models, set a cooking time, press Power or Power Level, and select a percentage or number before starting. Button sequences vary, and presets may lock the setting, so check the appliance manual.
