Reheating chicken, especially in a microwave, is a common practice in many households. We’ve all been there: enjoying a delicious chicken dinner one night and then wanting to savor the leftovers the next day. But is it safe? Concerns about food poisoning and bacterial growth often arise, leading many to question the safety of reheating chicken using this convenient kitchen appliance. This comprehensive guide will delve into the science behind reheating chicken, explore best practices, and address common concerns to help you confidently enjoy your leftover chicken while minimizing any potential risks.
Understanding the Risks: Bacteria and Reheated Chicken
The primary concern when reheating chicken, or any cooked food for that matter, is the potential for bacterial growth. Chicken, in its raw state, can harbor bacteria like Salmonella and Campylobacter. Proper cooking eliminates these harmful microorganisms. However, even after cooking, if chicken is left at room temperature for an extended period, bacteria can multiply and produce toxins. These toxins may not be destroyed by reheating and can cause food poisoning.
Temperature is key in understanding the safety of reheated chicken. Bacteria thrive in the “danger zone,” which is between 40°F (4°C) and 140°F (60°C). When cooked chicken remains within this temperature range for more than two hours, bacterial growth accelerates significantly. This is why it’s crucial to cool and refrigerate cooked chicken promptly.
The Danger Zone and Bacterial Growth
The danger zone is a critical concept to understand when dealing with food safety. The longer food sits within this temperature range, the higher the risk of bacterial contamination. Even if the chicken initially had a low bacterial count, leaving it out for an extended period can allow the bacteria to multiply to dangerous levels.
Time is also a crucial factor. The longer cooked chicken sits at room temperature, the more time bacteria have to multiply. The USDA recommends refrigerating perishable foods, including cooked chicken, within two hours. If the temperature is above 90°F (32°C), for instance, during a summer picnic, the timeframe is reduced to one hour.
Microwave Reheating: Challenges and Considerations
Microwaves offer a quick and convenient way to reheat food, but they don’t always heat food evenly. This uneven heating is a significant concern when reheating chicken, as it can create pockets where bacteria can survive.
Microwaves use electromagnetic radiation to heat food, and this energy doesn’t always penetrate thick or dense foods uniformly. The center of a chicken breast, for example, might not reach a safe temperature even if the outer edges are steaming hot.
Uneven Heating and Cold Spots
The uneven heating in microwaves can lead to cold spots within the chicken. These cold spots are areas where the temperature remains within the danger zone, allowing bacteria to persist and potentially cause illness.
Rotating the food during reheating can help to mitigate this problem. Stopping the microwave periodically and stirring or rearranging the chicken ensures that all parts of the food are exposed to the microwave energy more evenly.
Safe Reheating Practices: Step-by-Step Guide
To safely reheat chicken in the microwave, follow these guidelines:
- Proper Storage: Immediately after cooking and cooling slightly, store the chicken in an airtight container in the refrigerator. Ensure the refrigerator temperature is consistently below 40°F (4°C).
- Reheat Promptly: Don’t let the refrigerated chicken sit out at room temperature before reheating. Take it directly from the refrigerator to the microwave.
- Use a Microwave-Safe Container: Choose a container specifically designed for microwave use. Avoid using plastic containers that may leach chemicals into the food when heated.
- Add Moisture: Adding a small amount of water or broth to the chicken can help to prevent it from drying out during reheating and promote more even heating.
- Cover the Chicken: Covering the chicken with a microwave-safe lid or plastic wrap (with a vent) helps to trap steam and heat the food more evenly.
- Reheat to a Safe Internal Temperature: The most critical step is to ensure that the chicken reaches an internal temperature of 165°F (74°C). Use a food thermometer to check the temperature in multiple locations, especially the thickest part of the chicken.
- Rotate and Stir: During reheating, stop the microwave and rotate or stir the chicken to distribute the heat more evenly.
- Check Temperature Again: After rotating or stirring, continue reheating and check the internal temperature again to ensure it has reached 165°F (74°C) throughout.
- Eat Immediately: Once the chicken is reheated to a safe temperature, consume it immediately. Avoid letting it sit at room temperature again.
Using a Food Thermometer: A Must-Have Tool
A food thermometer is an essential tool for ensuring the safety of reheated chicken. Visual cues, such as steam or bubbling, are not reliable indicators of temperature. Only a food thermometer can accurately measure the internal temperature and confirm that it has reached 165°F (74°C).
Insert the thermometer into the thickest part of the chicken, avoiding bone. Check the temperature in several locations to ensure that it is consistently above 165°F (74°C).
Reheating Time and Power Levels
The reheating time will vary depending on the power of your microwave and the amount of chicken you are reheating. As a general guideline, start with 2-3 minutes on medium-high power. Then, check the internal temperature and continue reheating in 30-second intervals until it reaches 165°F (74°C).
Lower power settings can sometimes promote more even heating, but they will also require a longer reheating time. Experiment with different power levels to find what works best for your microwave and the type of chicken you are reheating.
What to Avoid: Common Mistakes When Reheating Chicken
Several common mistakes can increase the risk of food poisoning when reheating chicken in the microwave.
- Reheating Chicken Multiple Times: Reheating chicken multiple times significantly increases the risk of bacterial growth. Each time the chicken cools down and is reheated, it spends more time in the danger zone. It is best to only reheat chicken once.
- Reheating Chicken That Has Been Left Out Too Long: If cooked chicken has been left at room temperature for more than two hours (or one hour in hot weather), it should be discarded. Reheating it will not eliminate the toxins produced by bacteria.
- Overcrowding the Microwave: Overcrowding the microwave can prevent even heating. Reheat chicken in smaller portions to ensure that all pieces reach a safe temperature.
- Failing to Check the Internal Temperature: As mentioned earlier, relying on visual cues is not sufficient. Always use a food thermometer to verify that the chicken has reached 165°F (74°C).
- Using Inappropriate Containers: Avoid using containers that are not microwave-safe, as they may leach harmful chemicals into the food. Also, avoid using metal containers, as they can cause sparks and damage the microwave.
Beyond the Microwave: Alternative Reheating Methods
While the microwave is a convenient option, other methods can also be used to reheat chicken safely.
- Oven: Reheating chicken in the oven can help to retain moisture and achieve a more even temperature. Preheat the oven to 350°F (175°C), wrap the chicken in foil, and bake until it reaches an internal temperature of 165°F (74°C).
- Stovetop: Slicing the chicken and reheating it in a pan with a small amount of broth or sauce can also be a good option. Cook over medium heat, stirring occasionally, until the chicken is heated through and reaches 165°F (74°C).
Choosing the Right Method for Different Chicken Dishes
The best reheating method may vary depending on the type of chicken dish. For example, fried chicken may be best reheated in the oven to maintain its crispiness, while sliced chicken breast can be easily reheated on the stovetop.
Consider the texture and moisture content of the chicken when choosing a reheating method. Dry chicken may benefit from being reheated with added moisture, while crispy chicken may require a dry heat method to prevent it from becoming soggy.
Minimizing Risks: Additional Tips and Considerations
To further minimize the risk of food poisoning when reheating chicken, consider these additional tips:
- Cool Chicken Quickly: After cooking, cool the chicken as quickly as possible. Cut it into smaller pieces and spread it out on a clean plate to allow for faster cooling.
- Store Chicken Properly: Store cooked chicken in shallow containers in the refrigerator. Shallow containers allow the chicken to cool more quickly and evenly.
- Don’t Reheat Chicken That Looks or Smells Suspicious: If the chicken has an unusual odor or appearance, it is best to discard it. Don’t risk consuming chicken that may be contaminated.
- Be Extra Cautious with High-Risk Individuals: Pregnant women, young children, the elderly, and individuals with weakened immune systems are more susceptible to food poisoning. Take extra precautions when preparing and reheating food for these individuals.

Is it generally safe to reheat chicken in the microwave?
Yes, it is generally safe to reheat chicken in the microwave as long as you follow specific food safety guidelines. The key is ensuring the chicken reaches a safe internal temperature to kill any potentially harmful bacteria that may have grown during storage or cooling. Properly reheated chicken shouldn’t pose a food poisoning risk.
However, microwaving can sometimes heat food unevenly. This uneven heating can create cold spots where bacteria can survive, even if the rest of the chicken seems hot. That’s why using a food thermometer and following recommended reheating instructions is crucial for ensuring the safety and quality of your microwaved chicken.
What is the safe internal temperature for reheating cooked chicken?
The safe internal temperature for reheating cooked chicken, regardless of the cooking method, is 165°F (74°C). This temperature is high enough to kill any potentially harmful bacteria like Salmonella and E. coli that may have multiplied since the chicken was initially cooked. Using a food thermometer is the most reliable way to ensure this temperature is reached.
Insert the food thermometer into the thickest part of the chicken, avoiding bone. If the temperature reads 165°F or higher, you can be confident that the chicken is safe to eat. If it’s lower, continue microwaving in short intervals and checking the temperature until it reaches the required level.
How should I prepare chicken for reheating in the microwave to ensure even heating?
To ensure even heating when reheating chicken in the microwave, start by cutting the chicken into smaller, more uniform pieces. This helps the microwave energy penetrate the chicken more effectively, preventing cold spots. Also, add a splash of moisture, such as broth or water, to the container to help create steam and keep the chicken from drying out.
Arrange the chicken pieces in a single layer in a microwave-safe dish. Cover the dish with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape. This helps to trap moisture and promote even heating. Rotate the dish halfway through the reheating process to further ensure consistent temperatures.
How long should I microwave chicken to reheat it safely?
The exact time needed to microwave chicken safely varies depending on the power of your microwave and the size and thickness of the chicken pieces. A general guideline is to microwave on medium power for 2-3 minutes per piece of chicken. However, always prioritize reaching the safe internal temperature of 165°F (74°C) over adhering to a specific time.
Begin by microwaving for a shorter period and then check the internal temperature using a food thermometer. If it hasn’t reached 165°F, continue microwaving in 30-second intervals, checking the temperature after each interval, until it does. Overheating can make the chicken dry and rubbery, so aim for the minimum time necessary to reach the safe temperature.
Can I reheat chicken that has been previously reheated?
Generally, it is not recommended to reheat chicken that has already been reheated. Each reheating process provides an opportunity for bacteria to multiply if the chicken isn’t handled and stored properly. Repeated reheating increases the risk of exceeding the safe temperature window and promoting bacterial growth, potentially leading to food poisoning.
Ideally, only reheat the amount of chicken you plan to consume in one sitting. If you must reheat previously reheated chicken, ensure it reaches an internal temperature of 165°F (74°C) quickly and consume it immediately. However, for optimal food safety, it’s best to avoid reheating leftovers multiple times.
How should I store leftover chicken to ensure it’s safe to reheat later?
Proper storage of leftover chicken is crucial for preventing bacterial growth and ensuring it’s safe to reheat. Cool the cooked chicken as quickly as possible, ideally within two hours of cooking. Divide larger portions into smaller, shallower containers to speed up the cooling process. This reduces the time the chicken spends in the “danger zone” temperature range (40°F to 140°F) where bacteria thrive.
Store the cooled chicken in airtight containers in the refrigerator at a temperature of 40°F (4°C) or below. Use the leftover chicken within 3-4 days for optimal safety and quality. Always discard any leftover chicken that has been left at room temperature for more than two hours, or one hour if the ambient temperature is above 90°F.
What are the signs that reheated chicken is no longer safe to eat?
Several signs indicate that reheated chicken is no longer safe to eat and should be discarded. One of the most obvious signs is an off-putting smell or a slimy texture. These indicate bacterial spoilage. Also, look for any visible mold or discoloration on the chicken’s surface.
Even if the chicken appears and smells normal, if it has been stored improperly or for longer than the recommended 3-4 days, it’s best to err on the side of caution and discard it. If you are unsure about the safety of the chicken, it is always better to throw it away than to risk food poisoning. Food safety is paramount.
