How To Reheat Tempura? 3 Detailed Methods

#1. Reheating Tempura By Deep-frying

The most common method to revive uneaten fried dishes like tempura is using a deep pan or deep-fryer to heat them full of boiling oil. Yet, please be aware of the amount of oil you use for frying!

Here are the steps to do it:

  1. First, ensure that the oil in your pan or fryer comes around 350-375°F (or 177-190°C).
  2. Place some pieces into the hot oil one by one, and make sure you do not fry too many of them simultaneously.
  3. Next, wait for one or two minutes until they turn golden brown. You should also watch them carefully to avoid getting your deep-fried sushi overheated or burned. Otherwise, the food loses its good taste.
  4. Remove them from the fryer, then place the pieces on a kitchenware lined with oil absorbent papers to soak up all excess oil.
  5. Finally, grab a bite right away for good taste!

Note: When reheating the  dish by deep-frying, keep in mind that they should not be left in the oil for too long nor be clustered in the fryer. You do not want to bite soggy, oily deep-fried sushi, do you? 

#2. Reheating Tempura By Air Fryer

You can use an air fryer to reheat this fried food with little to no oil. Air fry is an amazing kitchen appliance, even when it comes to warming up different food, including fried ones.

This method is viewed as the quickest and most convenient method for busy homemakers. 

Here are the steps to do it:

  1. Start by preheating the air fryer between 350 and 400°F (or 177-204°C)
  2. Place the food you want to reheat on the frying rack as it gets hotter. Be sure to have enough space between the pieces in a single non-touching manner so that they can reheat adequately.
  3. Let them in the air fryer for about 3 minutes.
  4. Take out the tray and turn them over so that the other side can reheat evenly.
  5. Put them back in the air fryer for another 3 minutes.
  6. Check if they are ready or not. If not, put it back and reheat for 1-2 more minutes.
  7. Once done, place the pieces on paper towels or an oil drain rack (if any).
  8. Let cool and enjoy directly.

If you are reheating a large amount of deep-fried sushi, using your oven will also work quite well. As done right, this method is potentially the best way to help you bring back crispy deep-fried sushi pieces, like your first original ones.

Here are the steps to do it:

  1.  To ensure crispness, you must take the time to preheat the oven to 425°F (or 218°C). Remember to use a non-stick baking sheet and place it on the baking tray.
  2. Once it’s reached the proper temperature, take the hot tray out and spread a single layer of  deep-fried sushi on top.
  3. Next, please return it to the hot oven, and check the food every 3 minutes until it has reached the desired degree of crispiness.
  4. Remove the baking sheet from the oven and flip over the pieces to the other side.
  5. Put them back and reheat for a few more minutes.
  6. Once your food is done, take them out of the oven and gobble down those almost-as-good tempura before they cool down again.

What Are Some Useful Tips for Tempura Reheat

  • Apart from the three options described earlier, you can heat up deep-fried sushi in a toaster oven for about 6-12 minutes. Still, make sure you do not leave them in the refrigerator before reheating it by this method! Keep the cooked deep-fried sushi at room temperature instead.
  • A toaster oven is also a great option. To be more specific, let your deep-fried sushi sit in the oven for about five to ten minutes at a high temperature. Do not forget to keep track of the food, as you are reheating them at high heat!
  • Never try to reheat the dish more than once – It causes no good for your health!
  • Like other types of food, leftover tempura will only be best for you with just-once reheat. Repeatedly reheating food does not kill harmful bacteria; it stimulates toxic substances instead! 
  • Throw away tempura pieces that stay in the fridge for more than two to three days, as the texture and flavor will slump with time. Similarly, it would be best to discard tempura with an unpleasant/burning smell and those staying at normal temperature for over two hours.
  • It’s also important to keep your leftover dish in an air-tight food storage container. Do not forget to put parchment paper or wax paper between pieces so as not to let them touch each other.
  • The oil you use to reheat your dish plays a critical role as well. Amongst choices of oil such as canola, corn, peanut, safflower, etc. The vegetable one is always the best bet, while olive oil is a big NO.
  • If you want to reduce the heating time, lightly fry your deep-fried sushi before putting them in the fridge for storage. Of course, you must let them dry out of oil before storage.
