Grilled cheese sandwiches are a beloved comfort food, but sometimes you might have leftovers that need reheating. While some sources claim that grilled cheese sandwiches taste best straight out of the pan, you can still freeze and reheat them. The ideal reheating method depends on the time and equipment available to you. If you're short on time, you can use a microwave, but this may compromise the texture of the sandwich, making the bread soggy. To improve the texture, wrap the sandwich in a paper towel to absorb moisture. For better results, finish the sandwich in a preheated skillet to crisp up the bread.

Microwaving time: 15-second intervals
Microwaving is a quick way to reheat your grilled cheese sandwich, but it may compromise the texture and leave the bread soggy. If you're short on time, however, this method can be effective if you follow a few simple steps.
Firstly, place your sandwich on a microwave-safe plate. It is important to remove the sandwich from any foil or plastic wrapping before microwaving. If your grilled cheese is straight out of the refrigerator, heat it for 90 seconds on 50% power. If it is at room temperature, 30 seconds should be sufficient.
To ensure you do not overheat the sandwich and to monitor its progress, heat it in 15-second intervals, checking after each interval. This is particularly important if your sandwich is already warm, as you do not want to burn yourself or overcook the sandwich.
To improve the texture of your sandwich, wrap it in a paper towel before microwaving. The paper towel will help absorb any excess moisture, reducing sogginess.
After microwaving, you can finish off your sandwich in a preheated skillet for 30 seconds on each side to achieve a crisp texture.

Microwaving plate: use a microwave-safe plate
When using a microwave to reheat grilled cheese, it is important to use a microwave-safe plate. This is a crucial step to ensure the safety of your food and avoid any potential health hazards. Here are some detailed instructions on how to use a microwavable plate for reheating your grilled cheese:
First, ensure that you have a microwave-safe plate. Look for plates specifically designed for microwave use, as they are made of materials that can withstand the high temperatures and won't leach harmful chemicals into your food. These plates are usually marked with a microwave-safe symbol, which may appear as a wave pattern or the word "microwave-safe." Using regular plates not intended for microwave use can be dangerous, as they may contain materials that can leach into your food or cause damage when exposed to high heat.
Once you have your microwave-safe plate, place your grilled cheese sandwich on it. It is important to remove the sandwich from any foil or plastic packaging, as these materials can be unsafe in the microwave and may cause arcing or fires. Place the plate with the sandwich inside the microwave oven, being careful not to let the plate touch the sides, top, or bottom, as this can cause uneven heating and potential damage to your microwave.
Set the microwave timer according to the initial temperature of your sandwich. If the sandwich is at room temperature or slightly warm, start with shorter intervals of around 15 to 30 seconds. If your sandwich is cold, straight out of the refrigerator, you may need a longer duration, such as 60 to 90 seconds, but use 50% power. Every microwave is different, so adjust the timing based on your experience with your appliance. It is always better to start with shorter intervals and add more time as needed to avoid overcooking.
During the reheating process, it is crucial to monitor the sandwich closely. Microwaves can vary in intensity, and grilled cheese sandwiches can go from perfectly toasted to soggy or burnt very quickly. Check the sandwich after each interval, and if it needs more time, add another 15 seconds until it reaches your desired temperature. Remember that the goal is to melt the cheese and warm the bread without drying it out or making it soggy.
Finally, when the sandwich is heated to your liking, remove the plate from the microwave using oven mitts or potholders to protect your hands from the hot plate. Be cautious as the plate may be hot, and use a towel or oven mitt to handle it if necessary. Serve your grilled cheese sandwich on the plate and enjoy it while it's hot and cheesy!

Paper towel: wrap sandwich in a paper towel
Wrapping your grilled cheese sandwich in a paper towel before reheating in the microwave is a great way to improve its texture. This method helps to absorb the moisture that can make the bread soggy when microwaved.
To do this, place your sandwich on a microwave-safe plate and wrap it in a paper towel. You can then heat it in short bursts of 15 seconds, checking after each interval to ensure it doesn't overcook. This is especially important if your sandwich is still warm, as it will only need 30 seconds of heating. If you're taking your sandwich straight from the fridge, heat it for 90 seconds on 50% power.
If you want to further improve the texture and achieve a crispy exterior, you can finish the reheating process in a preheated skillet for 30 seconds on each side.
While the microwave is a fast option, it's important to note that it may not deliver the same taste and texture as other reheating methods, such as using a stovetop, oven, or toaster oven.

Stovetop: finish in a preheated skillet
While grilled cheese sandwiches are arguably best when fresh, you can still reheat them effectively. The stovetop method is a great option for reheating grilled cheese, especially if your sandwich hasn't been refrigerated. It's also possible to reheat cold sandwiches using this method.
To reheat your grilled cheese sandwich in a skillet, start by heating a pan over medium-high heat. Place your sandwich inside the pan and add a few drops of water. Cover the pan with a lid and let the sandwich heat up for 2-3 minutes. This helps ensure that the cheese melts to perfection. After this, remove the lid and crisp up each side of the sandwich for an additional 1-2 minutes.
You can also use a microwave to reheat your grilled cheese sandwich before finishing it in a skillet. Place the sandwich on a microwave-safe plate and heat in 15-second intervals, checking after each interval to prevent overcooking. You can also wrap the sandwich in a paper towel to help absorb moisture and improve the texture. Then, finish the sandwich in a preheated skillet for 30 seconds on each side to crisp up the bread.
If you're short on time or don't have access to a stove, there are alternative reheating methods. For example, you can use an oven, toaster oven, or air fryer. However, the stovetop method is a great option if you want to preserve the crispy exterior of your grilled cheese sandwich while achieving that gooey, melted cheese interior.

Oven: wrap sandwich in foil and bake at 350°F for 10-15 minutes
While grilled cheese sandwiches are arguably best when fresh, there are ways to reheat them while preserving their crispy exterior and gooey cheese interior. One way to do this is by using an oven.
First, preheat your oven to 350°F. While you're waiting for it to heat up, take your grilled cheese sandwich out of the fridge and unwrap it from the plastic or remove it from the sealed airtight container it was stored in. Then, wrap the sandwich in foil. Once the oven is preheated, put the wrapped sandwich inside and bake for 10-15 minutes.
The oven method is a great option if you're reheating a sandwich that's been in the refrigerator. It's also a good alternative if you don't have access to a stove or if you're short on time. However, it's important to note that grilled cheese sandwiches can be tricky to freeze and reheat due to the cheese's moisture content. High-moisture cheeses like young cheddar and American are commonly used for grilled cheese because they melt well, but they don't freeze well. When reheated, the cheese may not be as creamy as it was when the sandwich was first made.
If you're looking for a quicker reheating method, you might want to consider using a toaster oven, a stovetop, or a microwave. A toaster oven can mimic freshly made grilled cheese when used carefully. Using a stovetop with a frying pan is another popular method, as it preserves the crispy exterior while melting the cheese to perfection. Microwaving is the fastest reheating method, but it may result in soggy bread and a compromised texture.
