The Ultimate Guide to Reheating Food in the Microwave to Retain Nutrients
The microwave oven is an indispensable appliance in many households, renowned for its convenience in quickly heating up food. However, the conundrum of adjusting heating times for different types of food remains a perplexing issue for countless users.
Whether left out at room temperature or stored in the fridge, food tends to deteriorate and lose its appeal.
Reheating food in the microwave generates heat from within, quickly warming it from the inside out. This preserves the food’s quality and nutrients without the risk of wave exposure.
The safest and most reliable method, applicable to all types of food, is to reheat in intervals and check after each minute.
Soups and Broths
When it comes to liquid dishes like soups and broths, the microwave is your friend. Simply place the soup in a bowl (avoid metal) and heat it at 100 degrees Celsius for about 4 minutes. Be careful not to overdo it, as too much heat will cause the liquid to evaporate and your soup to become salty.
Grilled Dishes
Meat, fish, and vegetables are commonly grilled foods, and each requires a unique approach when reheating in the microwave.
For grilled meat and fish – Lightly coat the food with oil and place it on a heat-resistant glass plate. Set the microwave to grill or reheat mode at a temperature not exceeding 120 degrees Celsius for 5-10 minutes.
Boiled and Steamed Dishes
Besides grilled foods, boiled and steamed dishes are also commonly reheated. However, these should only be microwaved for a short time at medium power, approximately 2-3 minutes.
Baked Goods
Items like pizza, bread, and sponge cake are typically enjoyed fresh out of the oven, and their appeal diminishes as they cool. To reheat, wrap the item in specialized food-grade foil and place it in the microwave. Adjust the time between 3-5 minutes and the power level according to the type and quantity of the baked good. You’ll be treated to a warm and delicious treat, just like it came straight from the bakery.
Tips for Reheating Food in the Microwave
Spread food evenly on a plate and lightly coat the surface with oil to prevent dryness and sticking.
Never use metal containers in the microwave, as they can cause sparks and potential explosions.
Meat and fish require extra attention when reheating to avoid overcooking and burning.
Clean your microwave after each use to prevent food odors from lingering and to extend the appliance’s lifespan.
Avoid reheating oily foods in the microwave, as they can be challenging to clean and may pose a safety hazard due to uncontrollable heat.
Don’t use narrow-necked bottles or jars, as they can be difficult to remove and may cause burns.

Frequently asked questions
Use microwave-safe containers, preferably glass or ceramic. Avoid plastic containers as they can leach chemicals into your food when heated. Cover your food with a damp paper towel to create a steam pocket, which helps maintain moisture and prevents over-drying. Ensure an even reheat by stirring or rotating your food halfway through the heating process. Avoid overheating as this can break down nutrients. Use the defrost setting for gentle heating if your microwave has one.
For meats like chicken or beef, add a small amount of liquid (broth, water, or juice) to the container and cover with a lid or vented plastic wrap. This helps keep the meat moist and prevents it from drying out. When reheating vegetables, add a tablespoon of water and use a covered microwave-safe container to create a steaming effect, preserving their texture and nutrients. Soups and sauces should be stirred periodically to ensure even heating and prevent ‘hot spots’ that can burn your food.
Start with shorter heating times and increase in small increments as needed. This prevents overcooking and ensures your food doesn’t become rubbery or dry. Use the power level settings to adjust the microwave’s intensity. For example, use a lower power level for delicate foods like fish or eggs to avoid overcooking the exterior while keeping the interior moist. Refer to your microwave’s manual for specific instructions on power levels and their uses.
Some foods, like fried foods, tend to become soggy and lose their crisp texture when reheated in the microwave. It’s better to reheat them in the oven or air fryer to restore their original texture. Whole eggs with shells should not be microwaved as they can explode due to steam build-up. Instead, pierce the shell and microwave the egg in a bowl of water. Also, avoid reheating foods with ‘heat-and-eat’ packaging in the microwave, as the packaging may not be microwave-safe.
Always ensure your food is heated thoroughly to kill any harmful bacteria. Use a food thermometer to check the internal temperature of meats and casseroles. The USDA recommends heating foods to at least 165°F (74°C). Allow your food to rest after microwaving, as the heat continues to distribute, ensuring a more consistent temperature throughout the dish. Stirring during this resting period helps distribute the heat evenly.
