How to Reheat Egg Tart [Crisp Pastry + Luscious Custard]

Egg tart is a Chinese cuisine made from the combination of Portuguese and English cuisine pastel de nata and custard tart. The best way to enjoy egg tarts is when they are warm, which is why you need to learn to reheat them if need be.
There are three ways you can reheat egg tarts. You can reheat leftover egg tarts with an oven, a microwave, or an air fryer. However, using the oven is the best way to reheat an egg tart without making a mess of it. Fortunately, all methods do not take much time and are quite easy.
Having leftover meals is mostly inevitable, but the good thing is you do not have to always throw them out. So, in addition to learning the different ways to reheat egg tarts, you will also learn how to store leftover egg tarts in this article. Let’s get to it.
How to Reheat Egg Tart Using an Oven

As I mentioned earlier, the oven is the best appliance for reheating an egg tart without making it go soggy.
Here is how to use the oven to heat your egg tart:
- First, preheat the oven to a temperature of 350°F.
- Place the egg tart on the preheated baking pan or the wire rack inside the oven. Baking on a preheated surface will prevent the bottom from going soggy.
- Heat the leftover tart for about five to seven minutes. Check the pastry after 5 minutes to ensure it doesn’t dry out. You can leave it for more than seven minutes if need be, but ensure not to let it dry out. If you are not sure your tart is hot enough, you can dip the tip of a knife into it. If the blade is warm, then so is your pastry.
- Once the tart is hot, remove it from the oven and serve.
How to Reheat Egg Tart Using a Microwave
Using the microwave is another effective way to reheat egg tarts. It is almost as effective as the oven. But, you need to pay attention to the timing. Reheating the tart in a microwave longer than it needs to be might make the pastry dry out. Also, leaving it to sit in the microwave after heating can cause it to become soggy.

Here is how to reheat egg tart in the microwave:
- Remove the tart from the refrigerator or freezer and allow it to get room temperature. Reheating chilled egg tart is not a good idea.
- Bring out the microwave-safe plate and put the tart inside. If you have more than one tart, separate them from one another, so they don’t stick together.
- Set the timer to 30 seconds and heat at a medium temperature. Heat a few more times until the egg tart is heated through.
- Once it is hot enough, give it a few seconds to cool.
- Serve immediately and enjoy your hot tart.
How to Reheat Egg Tart Using an Air Fryer
We all want our leftover meals to taste as good as freshly made ones after reheating them. Using an air fryer to reheat leftover egg tart is a great way to retain its initial texture. An air fryer can be a good substitute for the oven if you understand how it works.
Follow the steps below to reheat leftover egg tart in an air fryer:
- Allow the egg tart to get room temperature if it is chilled.
- Set the air fryer to a temperature of 350°F.
- Lay the egg tart on the basket inside the air fryer. If there is more than one, ensure you separate the tarts.
- Heat the tart for about two to four minutes.
- Check the tart after two minutes to be sure they are not drying out. Stay close to the air fryer to ensure nothing goes wrong during the process. You can reduce the temperature of the fryer if the tarts are burning.
- Remove it from the fryer basket once it is heated through.
- Serve immediately and enjoy your hot egg tart.

How to Store Egg Tart
Food poisoning can occur when you reheat leftover meals many times or improperly. To prevent this from happening, store them in an airtight ziplock bag and keep them inside the refrigerator or freezer.
The refrigerator is the best place to store leftover egg tarts. However, you can also store them in a freezer.
Here’s how to store egg tart:
- Allow the pastry to get to room temperature
- Put it in an airtight container.
- Store in the storage facility of your choice. Egg tart you store in an airtight container can last for as long as five days in the refrigerator. Alternatively, it can last much longer in a freezer.
