Reheating food in the microwave is quick and convenient, but if done wrong, it can lead to uneven heating or dry, tough textures. To get the best results and keep your food safe, it’s important to follow a few simple steps.
Whether it’s leftovers or to-go orders, we’re always on the lookout for clever ways to make our food go further. Reheating food in the oven isn’t something to overlook. If you fail to reach the correct temperature or use the proper techniques could result in a soggy meal or, even worse food poisoning, an unpleasant illness that puts you out of action for a few days.
The bacteria either multiply astronomically or they produce poisons that can cause illness which can even be life-threatening. Based on the latest estimates we found 2.4m foodborne illness cases per year and the total burden for the UK is approximately £9bn from these. Reheating and cooling in the right way and ensuring food is at the correct temperature before eating can help you prevent this sort of illness and get the natural nutritional content and flavour of your meal.
7 Essential Things to Know about Reheating Food in the Oven
Reheating food in the oven involves setting the right temperature and time for each dish. For example, to reheat casseroles or baked goods, preheat the oven to 350°F (175°C).
According to the USDA, reheating food to an internal temperature of 165°F (74°C) minimizes the risk of foodborne illnesses, and most leftovers typically take 15–20 minutes to reach this temperature, depending on the dish.
Interestingly, every year, we buy around 10 million turkeys, yet more than 100,000 tonnes of poultry are thrown away—even though much of it is still perfectly edible. As a result, reheating food not only saves money and time, but it also plays a key role in reducing food waste, especially when you’ve cooked in bulk or ended up with too many leftovers.
However, not all reheating methods work well for every type of food. In some cases, they can leave your leftovers dry, soggy, or less appetizing. Therefore, it’s important to understand the best techniques for different foods. In this guide, we’ll explore which foods reheat best, the ideal temperatures to use, how many times it’s safe to reheat food, and helpful tips for reheating in the oven. Additionally, we’ll compare different reheating methods to help you make the most of your meals.
1. What temperature to reheat food in oven?
Reheating food to kill harmful bacteria is crucial. Use a thermometer to ensure the food is hot all the way through by inserting an instant-read probe into the thickest part.
The UK’s Food Standards Agency advises reheating food until it is steaming hot all the way through. While the FSA recognises time–temperature combinations such as 70 °C for 2 minutes as effective at killing bacteria during cooking, it does not specify exact temperatures or times for reheating food at home.
The other time and temperature combinations are:
- 60°C for 45 minutes
- 65°C for 10 minutes
- 70°C for 2 minutes
- 75°C for 30 seconds
- 80°C for 6 seconds
2. Can you reheat food in microwave twice?
Yes, you can reheat food in the microwave more than once, but it’s best to be careful. Each time you cool and reheat food, the risk of bacteria growing increases if it’s not stored or heated properly. To stay safe, always make sure the food reaches at least 75°C (165°F) all the way through before eating. That helps kill any harmful bacteria that may have started to grow.
However, even if it’s technically safe, reheating food multiple times isn’t ideal. The more you reheat it, the more it loses flavour, texture, and nutritional value. Things like meat can become dry or rubbery, and vegetables may get soggy. That’s why most experts recommend reheating only the amount you plan to eat at that moment.
The best tip? Cook or reheat food once, then store leftovers quickly in the fridge if needed. When you’re ready to eat more, reheat only what you’ll eat right away. This way, you avoid waste and keep your food safer and tastier.
3. How to properly reheat food in the oven?
Reheat food using the same method it was originally cooked with. For example, roast chicken should go back in the oven, and soup should be reheated in a pot.
Cover meats and casseroles with aluminum foil to prevent them from drying out. Reheat at a low temperature until the food reaches 70°C for at least 2 minutes. A meat thermometer can help ensure the food is heated through properly.
Preheating the oven is helpful when reheating food. Warming up food alongside the oven helps maintain moisture. Stir halfway through, if possible. A meat thermometer can confirm the food reaches the correct temperature.
4. What food should not be heated in a microwave?
Some foods shouldn’t be heated in the microwave. These include whole eggs (raw or hard-boiled), processed meats like hot dogs and sausages, grapes, chili peppers, frozen meat, seafood, rice, potatoes, and fried or crispy foods. They can explode, lose texture, or release harmful substances.
Microwaving whole eggs can cause dangerous steam buildup, making them explode. Processed meats might form harmful compounds when reheated. Also, avoid microwaving food in plastic containers that aren’t microwave-safe because they can melt and leak chemicals.
For safety, don’t reheat food stored longer than two days or left out at room temperature over two hours. Starchy foods like rice need extra care since bacteria can survive if not heated properly. Always fully defrost frozen leftovers before reheating and eat them within 24 hours.

6. How long to reheat rice in microwave?
Reheating rice in the microwave requires care to ensure safety and good texture. Always add 1-2 tablespoons of water per cup of rice to keep it moist. Place the rice in a microwave-safe bowl, cover it with a microwave-safe lid or damp paper towel, and heat in 30-second intervals.
Stir the rice between intervals to help heat it evenly. It usually takes about 2 to 3 minutes total. Make sure the rice is steaming hot all the way through, reaching at least 165°F (74°C) to kill any bacteria.
Remember, leftover rice should be cooled quickly after cooking and stored in the fridge for no more than one day before reheating. Takeaway rice is best eaten immediately as it might have been reheated already.
7. How to prevent food from drying in the microwave?
Reheating food in the microwave is quick and convenient, but it often leads to dry, tough meals if not done properly. The key to keeping your leftovers moist and delicious lies in how you heat them. By using simple techniques to retain moisture and evenly distribute heat, you can enjoy reheated food that tastes just as good as when it was freshly cooked. Here’s how to prevent your food from drying out in the microwave.
– Cover the Food: Use a microwave-safe lid, plastic wrap (leave a small vent), or a damp paper towel to trap steam and moisture. This helps keep food from drying out by creating a steamy environment inside.
– Add Moisture: Sprinkle a little water, broth, or sauce on the food before heating, especially for dry items like rice, pasta, or meats. This added moisture turns into steam while microwaving, keeping food moist.
– Heat in Short Intervals: Microwave food in 20–30 second bursts, stirring or flipping between intervals. This prevents overheating and drying out any one spot.
– Use Lower Power Settings: If your microwave has power levels, use medium or medium-low to heat food more gently and evenly.
– Place a Cup of Water: Sometimes placing a microwave-safe cup or bowl of water inside while heating can increase humidity in the microwave, reducing dryness.
– Heat Similar Items Together: Heat foods that require similar times and temperatures together to avoid overcooking some parts while others remain cold.
How to reheat food with a microwave?
Different foods have different heating needs, and microwaves don’t always heat evenly. That means you need to reheat food in stages. For example, meat may take longer than vegetables, and pasta dishes benefit from lower power and added moisture to avoid drying out.
Using a microwave is quick and efficient, but there are best practices to follow. Place food in a microwave-safe container, cover it loosely, and heat in short intervals—stirring halfway through—to make sure it warms evenly and safely.
Heating food the right way in the microwave helps retain flavor, texture, and safety. Knowing how to adjust power, timing, and moisture for each food type makes microwave reheating more effective.
Can you Reheat Fish?
Reheating fish can be tricky. Overcooked fish becomes dry and rubbery, so it’s important to do it gently and safely. The best method is using a low-temperature oven to warm the fish until it reaches an internal temperature of 54°C to 63°C (130°F to 145°F). This helps preserve its moisture and texture.
Whitefish reheats best when covered in a sauce or wrapped loosely in foil before placing it in the oven. This prevents it from drying out. Thin, breaded fish is better reheated under the grill or in an air fryer to maintain its crispness. Whichever method you choose, the fish should flake easily with a fork when done. This ensures it stays tender and flavorful.
How long do you reheat cold Pizza in the microwave?
Microwave your pizza slice on medium heat for 30–60 seconds. To keep the crust from going soggy, place a small cup of water in the microwave alongside the pizza. If it’s not hot enough, continue heating in 20-second intervals, rotating the slice for even warming.
This method gives you soft, gooey cheese and a slice that stays moist—not rubbery!
Can You Reheat Chicken?
Reheat roast chicken by adding it to a new dish like curry or risotto. Ensure it’s hot all the way through, with an internal temperature of at least 74°C (165°F). Cover the chicken with aluminum foil in the oven to keep it moist while reheating. You also get more information’s from our latest article of Can You Reheat Chicken?

Some Additional Tips
1. You should not defrost food at room temperature. It is best to leave to thaw in the fridge overnight because bacteria thrive when temperatures climb above 8°C (46.4°F). You can also use the defrost setting on your oven if you are short on time. There are different methods of freezing between fruits and Thanksgiving turkey.
2. Sometimes you need to cut your food into small and equally sized pieces to help the reheating process more quickly and evenly. Bite-sized pieces will definitely take less time to reach a safe temperature than big chunks.
3. Take your sweet time to reheat your favourite food as reheating slowly helps retain its flavour and texture. Foods that should be crisp (such as the skin on a jacket potato or golden breaded chicken) reheat best on a lower temperature in the oven – around 170°C (340°F) should do the trick. Do not wrap these foods too tightly in foil; otherwise, water will become trapped, making your food soggy.
4. Before reheating rice in the microwave, drop an ice cube into it. This will help keep the grains moist when recooking. Make sure it is piping hot throughout before serving and serve immediately. Cooking rice perfectly is an art and you need sheer patience and dedication to do so.
5. You should always check food labels in case they include any instructions for reheating later. Follow them carefully if they do. Stir throughout heating if required, especially to avoid cold spots in sauces and soups and allow the food to stand if instructed.
