Can You Reheat McDonald’s Filet-O-Fish The Next Day? 

Yes, you can reheat a McDonald’s Filet-O-Fish sandwich the next day after you buy it. As long as the sandwich is stored correctly to make sure it stays fresh throughout, there will be no issues with reheating it the next day. 

Reheating McDonald’s food, including their Filet-O-Fish sandwich, is simple enough. But again, it is also more complex than reheating any homemade food. Specific parameters must be considered while reheating the sandwich, especially if it is done the next day. 

These parameters are essential to ensure that the sandwich’s texture remains the same once done. But, regarding reheating the next day, proper storage is just as necessary to avoid the sandwich from getting dry or mealy in texture. 

Best Ways To Reheat McDonald’s Filet-O-Fish

As mentioned earlier, four essential ways to reheat a Filet-O-Fish sandwich exist. The four methods may give varying results as they are different. 

But overall, all four methods will surely get the job done, that too in a significant way. In this section, you will find detailed guidelines on reheating this classic McDonald’s sandwich in all the methods mentioned. 

How To Reheat McDonald’s Filet-O-Fish In Microwave? 

The microwave is the easiest and most efficient way to reheat a Filet-O-Fish sandwich. This method is quick and accessible whenever you are in a hurry, and your sandwich will be hot again soon! Here is how you can go about it. 

  1. Scrape the tartar sauce off the bun, as it will likely split during reheating. 
  2. Next, reassemble the sandwich and wrap it in a paper towel to soak the extra moisture while ensuring the buns don’t dry out. 
  3. Place the sandwich on a microwave-safe plate and heat it twice at high heat for 30-second intervals. 
  4. Once the sandwich is hot, please remove it from the microwave and let it cool down for about 30 seconds. 
  5. Apply the tartar sauce back on the buns, assemble, and enjoy your delicious sandwich! 

How To Reheat McDonald’s Filet-O-Fish In Oven?

Try the oven if you have extra time and will wait a little longer while getting crispy toasted buns. Reheating this sandwich in the oven will give it a crisper finish than the microwave does, and that too in a good way. Follow these steps to heat Filet-O-Fish in the range: 

  1. Remove the tartar sauce from the sandwich by scraping it off. 
  2. Preheat the oven to 350 degrees Fahrenheit. 
  3. Place the fried fish filet on a baking tray and heat it in the oven for 4-5 minutes.
  4. Next, remove the filet and let the buns heat for 2-3 minutes. Sprinkle a little water on the buns to prevent them from drying out. 
  5. Take the buns from the oven, spread the tartar sauce back on the buns, place the fish filet, and enjoy! 

How To Reheat McDonald’s Filet-O-Fish In Air Fryer? 

Like an oven, an air fryer is also a great way to achieve those crispy edges with this sandwich while ensuring it does not dry out. This method is similar to an oven. If you don’t have a range and want a similar texture, here is how to reheat. 

  1. Scrape off the tartar sauce in a bowl and keep it aside. 
  2. Preheat the air fryer to 400 degrees Fahrenheit. 
  3. Place the fried fish filet in the basket, and let it heat for 5 minutes. 
  4. Take the fish out and place the buns in the air fryer with the cut side facing down. 
  5. Sprinkle some water on the buns, and let them heat for 2 minutes. 
  6. Take the buns out of the air fryer, spread the tartar sauce on them, place the filet in between, and there you have it! 

How To Reheat McDonald’s Filet-O-Fish In A Pan? 

Lastly, if your kitchen lacks fancy equipment, you can still heat a Filet-O-Fish sandwich at home. Heating this sandwich in a pan is also an excellent option to keep the flavor intact. 

  1. Remove tartar sauce from the buns, keep it in a separate container, and set aside. 
  2. Place a pan on medium heat, and add the fish filet. 
  3. Cover the pan with a lid and let the filet heat up with its steam while ensuring the fire is at medium or low heat. This process should take about 4-5 minutes. 
  4. Take the filet off the pan and place the sandwich buns in the same pan, with the cut portion facing down. 
  5. Sprinkle some water on the sides of the pan, cover it with a lid, and let the buns heat for a few minutes. 
  6. Take them off the pan, reassemble the sandwich, and enjoy while hot! 

Can You Reheat McDonald’s Filet-O-Fish With The Wrapper On? 

Yes, you can reheat McDonald’s Filet-O-Fish sandwich with the wrapper on. However, this can only be done if the sandwich is reheated in the microwave. Moreover, it would still be essential to scrape off the tartar sauce before reheating to ensure it does not split. 

Tartar sauce, a derivative of mayonnaise, is a cold sauce made by emulsion. If it is exposed to high temperatures, it will split for sure. So, even if you plan on heating your sandwich in the microwave, it is best first to scrape off the tartar sauce to prevent these issues. 

Moreover, heating McDonald’s Filet-O-Fish with the wrapper on is something you should do only in the microwave and oven. Reheating with the wrapper on will not work well if the sandwich is heated in the air fryer or a pan. 

Can You Freeze A McDonald’s Filet-O-Fish? 

You can freeze a McDonald’s Filet-O-Fish sandwich if you want to eat it later. McDonald’s food is perfect for freezing and will stay the same quality while frozen if the process is done correctly. 

McDonald’s Filet-O-Fish, just like most other food that the chain has to offer, can very quickly be frozen. Freezing the sandwich will ensure it stays fresh for a couple of months and can be eaten any time then. 

But, it is also essential to know that just as the reheating process has to be done correctly, the same applies to freezing the sandwich. If the sandwich is not kept in the freezer properly, it will dry and taste rubbery. So, here is how you can freeze this sandwich while ensuring the quality remains top-notch. 

  1. Wrap the sandwich in either its original wrapping paper or in a piece of aluminum foil. 
  2. Place the sandwich in an air-tight container or bag. 
  3. If storing it in a freezer bag, remove all the excess air to avoid any freezer burn. 
  4. Place the air-tight container or freezer bag in the freezer for up to two months. 

How To Reheat A Frozen McDonald’s Filet-O-Fish Sandwich? 

Compared to other burgers and sandwiches McDonald’s offers, it is best to reheat this sandwich only when frozen. The reason again is tartar sauce. Sure, if you can manage to scrape the tartar sauce off the bun while it is still frozen, it is okay to reheat this sandwich even when it is still frozen. Regardless, here are two methods to heat this sandwich properly. 

In The Oven: 

  1. If you are reheating the frozen sandwich in the oven, make sure it is completely thawed before you do so. 
  2. Preheat the oven to 350 degrees Fahrenheit. 
  3. Scrape off the tartar sauce and wrap the sandwich in a paper towel to soak excess moisture. 
  4. Place the sandwich on an oven-safe tray and let it heat in the oven for 5 minutes. 
  5. Once hot, remove it from the range, spread the tartar sauce back on, and enjoy! 

In The Microwave: 

  1. This method can be used even while the sandwich is frozen, as long as you scrape off the tartar sauce. 
  2. Wrap the sandwich in a paper towel and place it on a microwave-safe plate. 
  3. On the first go, heat the sandwich at 50% for 30 seconds. 
  4. Then, heat the sandwich twice for 30-second intervals, but this time on full heat. 
  5. After the sandwich is hot, take it out of the microwave, spread the sauce back on, and serve hot! 

Can You Reheat A McDonald’s Filet-O-Fish More Than Once? 

Can you reheat McDonald's Filet-O-Fish More Than On

It is best to reheat a McDonald’s Filet-O-Fish sandwich only once. While reheating once is okay, more than once could cause the growth of harmful bacteria since the sandwich has undergone too many temperature changes. 

McDonald’s food is undoubtedly made to stay fresh for a long time and be reheated when necessary. However, reheating more than once is not an ideal practice since that causes too many changes to the temperature of the sandwich. 

Instant and too many temperature changes can be the perfect breeding ground for harmful bacteria to grow. If you cannot finish the sandwich after reheating it, it is best to throw it away rather than store it and reheat it again.

Is It Worth Reheating McDonald’s Filet-O-Fish At Home? 

It is worth reheating a McDonald’s Filet-O-Fish sandwich at home. McDonald’s food has been made in a way that will taste good even after it is reheated, and hence, it is undoubtedly worth storing the sandwich for the next day. 

Although it is worth reheating this sandwich at home, the eventual quality of the sandwich once it is reheated also depends on how well it was stored. If the storage and reheating parameters are adequately taken care of, I can guarantee that your sandwich will taste just as fresh and delicious as when you first bought it!
