Can you reheat mashed potatoes in the microwave?
The Best Tool for the Job? It’s Your Microwave – Some people will discourage using a microwave for reheating mashed potatoes, likely because microwaved mashed potatoes sometimes turn out gummy. But that’s not the microwave’s fault. It’s actually due to user error.
- It’s very easy to get something extremely hot in a microwave.
- Like, depending on how much food you’re reheating, you can achieve 131 to 185 F within a matter of seconds.
- But that doesn’t mean a microwave is no good for reheating mashed potatoes.
- It’s actually perfect for the job.
- No other technique works as well.
Reheating on the stovetop can cause mashed potatoes to stick to the bottom of the pot. A slow cooker can take an hour or longer. Reheating in the oven can work for smaller amounts, but it still takes too long. And using a double boiler is just way too much trouble.
- The microwave, it turns out, is actually perfect for reheating mashed potatoes.
- Simply add your mashed potatoes to a microwave-safe bowl, along with a tablespoon or so of milk or cream.
- Cover the bowl tightly with plastic wrap and microwave on 50 percent power for 60 seconds.
- Stir, taste for heat, and repeat as necessary, heating for 60 seconds at a time, stirring in between, until you achieve the right temperature.
These 60 second bursts at 50 percent power ensure that the potatoes never get too hot, thus ensuring that they turn out creamy, not gummy.

- This is when cooked foods sit out between temperatures of 40°F and 140°F.

Can you eat leftover potatoes?
Foods You Shouldn’t Reheat Microwave Photo: Brett Stevens/Getty Images You’ve never met a problem the microwave couldn’t solve, right? Wrong. So wrong. Before you heat up those leftover potatoes, you might want to read this first. I live alone, which means I usually cook things I can eat in one sitting.
- But occasionally, I have leftovers.
- As convenient as it is to pan-fry one juicy chicken breast on a hectic weeknight, sometimes I want a casserole, a pasta dish, or soup-all meals that weren’t necessarily created with single folks in mind.
- And when I cook those dishes to enjoy for more than one meal, the microwave becomes my reliable companion throughout the week.
Or, at least it used to be before I discovered that reheating certain items can be a health hazard. Certain cooked ingredients, if reheated (particularly after being stored improperly), can actually make you physically ill. And I don’t say that to rile up panic, it’s simply important to be aware of the fact that heating foods changes their chemical structure, and for some ingredients, these changes that are spurred by temperature shifts can make the food incompatible with the human digestive system. Spinach Sautéed too much spinach for a quick and nutritious side dish at dinner? If you can’t eat it all right after it’s cooked, it’s best to just toss it or eat the leftovers cold (maybe stir them into a pasta salad). To avoid food waste in the future, aim to cook only what you need for the meal at hand.
- Spinach contains a high quantity of nitrates, which provide vital nutrients our bodies need to function.
- When we eat certain vegetables raw, something magical happens in the body that turns those good-for-you nitrates into nitrites.
- Nitrates don’t become a problem until the heating process activates them, prompting them to release poisonous carcinogenic effects when the body processes them.
Every time you reheat spinach or other veggies that are rich in nitrates, they become increasingly toxic. gettyimages-51101394.jpg Potatoes Here’s the deal on those spuds. When cooked potatoes are left out at room temperature or warmed up for a second time, they can take a toxic turn for the worst. Why? Warm temperatures promote the growth of the rare bacteria, botulism, that is commonly found in potatoes.

How long are leftovers in the fridge good for?
Leftovers can be kept for three to four days in the refrigerator. Be sure to eat them within that time. After that, the risk of food poisoning increases. If you don’t think you’ll be able to eat leftovers within four days, freeze them immediately. Food poisoning — also called foodborne illness — is caused by harmful germs, such as bacteria in contaminated food.
Because bacteria typically don’t change the taste, smell or look of food, you can’t tell whether a food is dangerous to eat. So if you’re in doubt about a food’s safety, it’s best to throw it out. Fortunately, most cases of food poisoning can be prevented with proper cooking and food handling. To practice food safety, quickly refrigerate perishable foods, such as meat, poultry, fish, dairy and eggs.
Don’t let them sit more than two hours at typical room temperature or more than one hour at temperatures above 90 F (32 C). Uncooked foods, such as cold salads or sandwiches, also should be eaten or refrigerated promptly. Your goal is to reduce the time a food is in the “danger zone” — between 40 and 140 F (4 and 60 C) — when bacteria can quickly multiply.
