Apple crumble is one of the most popular desserts out there. The rich, stewed apple base is in stark contrast to the sweet biscuit crumble, and it’s a dessert that is just begging for a topping of thick pouring cream or homemade custard!

Whether your crumble contains apples, pears, blackberries, or any other stewed fruit for that matter, you might be wondering what to do with the leftovers. Can you reheat it? 

To reheat apple crumble, pop it into the oven for around 20 to 25 minutes until hot through. If you’re short on time, you can also microwave it in a few minutes.

How to Reheat Apple Crumble

Reheating apple crumble is straightforward, but your chosen method will dictate its taste and texture. Reheating apple crumble in the oven ensures it has a relatively crispy topping while doing so in the microwave will make the crumble a little softer. 

If you’re not so concerned with a crispy top, then the microwave is your best bet as it is considerably quicker.

Another important thing to note is that you should only use the microwave to reheat portions of apple crumble. If you’re reheating a whole dish, you should do so in the microwave. 

Whichever method you choose, the result will be a hot and tasty apple crumble that can then be topped with homemade custard or thick pouring cream – perfection! Let’s dive in and take a look at each method in detail:

How to Reheat Apple Crumble in the Oven

As mentioned, reheating apple crumble in the oven will yield the most pleasing results. Here’s how to go about it: 

  1. Remove Crumble From the Fridge/Freezer
    Leave your apple crumble to stand at room temperature for around thirty minutes before you reheat it. If you have frozen your crumble, you should defrost it in advance. 
  2. Preheat Oven
    Switch on your oven and preheat to 350F or 175C. 
  3. Prepare Crumble
    If it isn’t in one already, transfer your apple crumble to an ovenproof dish. Melt a small amount of butter and drizzle it on top of the crumble to prevent it from drying out. 
  4. Reheat
    Place your apple crumble – uncovered – in the centre of your oven and allow it to reheat for 20-25 minutes. 
  5. Check for Doneness
    When you think the crumble is hot, remove it from the oven and check for doneness. If you have one, you can use a thermometer to check the internal temperature is at least 75C or 165F before serving.
  6. Serve and Enjoy
    Split your apple crumble into individual portions and serve up with custard or cream. 

How to Reheat Apple Crumble in the Microwave

If you want to reheat a portion of apple crumble more quickly, you can do so in the microwave by following these steps: 

  1. Prepare Crumble
    Add your portion of apple crumble to a microwave-safe plate or dish. 
  2. Cover
    Place a paper towel over the crumble and add the dish to the microwave. 
  3. Reheat
    On full power, reheat your crumble in thirty-second bursts. 
  4. Check for Doneness
    When you see steam coming from your crumble, check it for doneness. You can use a thermometer to check the internal temperature is 75C or 165F before serving. 
  5. Serve and Enjoy
    When piping hot, your apple crumble is ready to serve up and enjoy.

How to Reheat Apple Crumble Successfully

To have complete success when reheating apple crumble, here are our 3 vital tips to follow:

  • For Crispy Crumble, Use the Oven – If one of your favourite things about apple crumble is its crispy topping, then you should reheat it in the oven. Reheating crumble in the microwave will cause the topping to soften, which isn’t the ideal texture for some people. 
  • Reheat Custard Separately – For many, custard and crumble go hand in hand. But if you’re reheating leftovers of both, it’s a good idea to keep them separate. This is mainly to ensure they both reheat evenly and also to prevent the custard from causing the crumble to go soggy.
  • Defrost First – If you’re planning to reheat frozen apple crumble, make sure you thaw it completely beforehand. The best way to defrost frozen crumble is in the fridge overnight, but you can also do so on your microwave’s defrost setting if you’re tight for time in the kitchen.

Is It Safe to Reheat Apple Crumble?

Yes, reheating apple crumble is totally safe. Stewed apples can spoil if you leave them sitting out at room temperature, so just make sure you wrap your leftover crumble well and get it in the fridge or freezer as soon as you can.

But other than that, you shouldn’t encounter any issues when you come to reheat your apple crumble, making it an excellent dessert to prepare ahead of time. 

Reheating Apple Crumble FAQs

If you still have further questions about reheating apple crumble then these might help you out:

Can You Reheat Apple Crumble Twice?

Can You Freeze Apple Crumble?
