How to Reheat Custard

Custard is a delightful dessert, enjoyed by many around the world.

It is typically made by heating milk, cream, egg yolks and sugar together on a stovetop.

The mixture is then cooled down and infused with vanilla flavoring.

Custard can be eaten both warm or cold and can be used in many different desserts like pies or tarts.

In this article, we will be exploring different methods of reheating custard.

Whether you’ve made too much custard and looking to store it for later use, or you want to reheat leftover custard from the fridge, we have got all your questions covered.

How to Reheat Custard

Different Reheating Methods for Custard

Before we dive into the specifics of reheating custard, let’s go over which methods are appropriate:

  • Microwave
  • Oven or Toaster Oven
  • Stovetop
  • Steaming
  • Air Fryer

All these methods are suitable for reheating custard; however each method may yield different results in terms of creaminess and consistency.

How To Reheat Custard Using Different Methods


Microwaving is perhaps one of the quickest ways to reheat custard. However, it does require some attention as you don’t want your custard turning into scrambled eggs! Here are some steps to follow:

  1. Take your container of custard and place it in a microwave-safe dish.
  2. Set the microwave power level at 50%.
  3. Microwave for 30 seconds at a time.
  4. After every 30 seconds remove the container from the microwave and stir thoroughly.
  5. Repeat until you reach the desired temperature.

Note: Be careful not to overheat as this can cause curdling.

Oven or Toaster Oven

Reheating using an oven/toaster oven requires more time than using a microwave but may yield better results in terms of consistency. Here’s how to do it:

  1. Preheat your oven/toaster oven to 325°F.
  2. Pour your custard into an oven-safe dish.
  3. Cover the dish with foil paper to prevent moisture loss.
  4. Place the dish in the preheated oven and let it heat for 15-20 minutes, or until the desired temperature is reached.
  5. Remove from oven and let cool for a bit before serving.


Reheating on a stovetop is another efficient method of reheating custard, and you have better control over the heat applied than with other methods.

  1. Pour your custard into a small pot/pan.
  2. Heat on low heat, stirring continuously so that no curdling occurs.
  3. Keep stirring until the custard reaches its desired temperature (do not boil).
  4. Remove from heat and let cool for a bit before serving.


Steaming is another gentle method of reheating custard that can help maintain its consistency and creaminess.

  1. Fill a pot with water and bring to a boil.
  2. Pour your leftover custard into a metal bowl that fits snugly on top of the pot (without touching the water).
  3. Cover tightly with foil paper or plastic wrap to prevent moisture loss
  4. Steam for about 10-12 minutes, checking regularly until desired temperature is reached.
  5. Take off from steam, let cool for some time before serving.

Air Fryer

Air fryers are becoming increasingly popular as they are safer than traditional deep fryers and require less oil use while maintaining crispness without any extra breading needed.

  1. Place your leftover custard in an air fryer safe container/dish
  2. Set air fryer at 250 degrees Fahrenheit
  3. Heat up custard for around 10-15 minutes depending on how much you have; ensure to check regularly.
  4. When custard is heated, remove from air fryer and let rest for a few minutes before serving.

Tips for Reheating Custard

Reheating custard can be tricky as it requires maintaining the right texture and flavor. Below are some tips to help you achieve optimal results when reheating:

  1. Thaw your custard if it is frozen by placing it in the fridge overnight or leaving it out at room temperature.
  2. Ensure that you use the appropriate reheating method for your custard type.
  3. Cover your custard dish tightly with aluminum foil, plastic wrap or a lid to retain moisture and prevent skin formation.
  4. Small portions of custard reheat better than large portions, so consider dividing leftovers into smaller servings before reheating.
  5. Adjust temperature settings to correspond with portion size.

Is It Safe to Reheat Custard?

Reheating any food raises safety concerns, including bacterial growth and spoilage. However, if proper procedures are followed during preparation and storage, then reheated custards should be safe for consumption.

It is important not to let the custard sit at room temperature for more than two hours, keeping it refrigerated below 40 degrees Fahrenheit when storing leftovers, and ensure multiple cycles of heating do not occur.

Safety Tips include:

  1. Checking all ingredients used in making the original batch of custards
  2. Ensuring that you heat your custards until they reach an internal minimum temperature of 165 degrees Fahrenheit
  3. Avoid reheating large batches of leftover cooked foods more than once as this increases bacterial growth chances.

Frequently Asked Questions

Can I reheat my frozen custards?

Yes! Simply thaw them out ahead of time or gently reheat them using gentle-to moderate heat methods like steaming

Can I add additional milk to my pre-made custards when reheating?

Yes, you can add milk to your custard to improve its creaminess consistency.

Can I store leftover custard after reheating it?

Storing leftover reheated custards is not recommended, as the process could affect taste and texture resulting in unsatisfactory results.

Common Mistakes to Avoid

Avoiding some common mistakes when reheating custard will help you maintain its flavor and texture. Below are a few mistakes to avoid:

  1. Overheating or uneven heating of the custard.
  2. Not allowing sufficient time for thawing out or defrosting before reheating.
  3. Using an incorrect reheating method for the specific type of heat source used.
  4. Neglecting to adjust temperature and time according to portion size while maintaining proper stirring intervals
  5. Ignoring food safety guidelines, i.e., letting sitting food sit out in room temperature before storage or ignoring expiration dates.

Reheating custards is easier than most people think! By following these guidelines on how best to reheat your pre-made desserts, you’ll be sure they taste nearly as good as freshly made ones!
