Can you reheat apple crumble ?

Yes, you can reheat apple crumble by using a medium heat, be it in the oven or in the microwave. The best option is to first heat it in the microwave so it’s heated all the way through, then to leave it in the oven for another 10-15 minutes so the top gets nice and crunchy again.

The thing about apple crumble is that it can be really loose, if you don’t use a pie crust on the bottom. This makes the pie something you have to reheat in one sitting, because scooping it out will be a real mess. If your apple crumble has a pie crust, it may be easier to slice and reheat a single serving.

Now let’s take a look at how to reheat apple crumble.

1. Reheat apple crumble in the microwave

The simplest, fastest method is to use the microwave. Make sure you have a plate with raised edges, especially if the crumble is very loose and has no crust on the bottom. You also need a microwave-safe bowl on top, to make sure it doesn’t dry out on the top.

This should be done in about 2-3 minutes, depending on the strength of your microwave. Be sure to use medium heat, otherwise you’ll get too uneven a heating !

If you like you can then transfer the crumble to the oven for about 10 minutes, to make sure the top gets crispy.

If you’re reheating the entire apple crumble in its original tray, check the material. if it’s any sort of metal, do not put it in the microwave, and instead use the oven. If it’s glass or ceramic, it’s alright for the microwave as well as the oven.

2. Reheat apple crumble in the oven or toaster oven

If reheating in the oven from the fridge, know that the pie will take a while to get to the right temperature The upside to this is that you may get a crispier finish, as the oven will dry it out a little.

The downside is that it takes much longer than a microwave. Make sure you use medium-low heat in your oven, even if it takes longer. If you use high heat, the edges of the pie will start to brown and burn by the time the middle or thickest part is hot enough to eat.

On average this method can take 20-30 minutes, depending on how hot you want the pie in the first place.

3. You can eat apple crumble cold

Another option is to simply eat the pie cold, as-is. Some people even prefer it this way, since it’s a dessert and they can’t have desserts any other way. Personally, we’re fine with hot and cold pie, but if you’d rather have cold pie the apple crumble may taste even more delicious.

Can I bake apple crumble ahead of time ?

Yes, you can bake apple crumble pie ahead of time, store it somewhere cool, and serve it the next day after reheating. This way you can definitely get a nice, crispy top and the flavors will have time to really mix together.

The only downside is if you’re using pie crust on the bottom. You may end up with a soggy bottom, and it may be hard to portion the pie the next day in this case. It’s up to you how you want to bake your pie.

How long can I leave apple crumble in the fridge ?

Apple crumble can be left in the fridge for up to 3 days after baking, provided it’s kept in an airtight container and is at least room temperature when you put it in the fridge. If you’re putting the entire baking dish, opt for cling film or saran wrap, and do a double cover, to make sure the pie is properly sealed.

If you use aluminum foil it’s a very loose top, and the pie may spoil much quicker than you’d like.

Can you leave apple crumble out overnight ?

We don’t recommend leaving the apple crumble on the counter overnight, unless you have a very cold kitchen that. If you do decide to leave it out, make sure to cover it, to protect it from dust and any stray bacteria or spores. Or pets, if you have any that would be curious about that pie.

Just a few hours are fine if you’re not leaving it out for 24 hours. A warm, moist environment promotes the spread of germs, and it’s best to not risk it. Try and make room for the pie in the fridge, or at least in the pantry if it’s a cold one.

Can you freeze apple crumble ?

Yes, you can freeze apple crumble and store it for as long as 6 months. Be sure to use an airtight, freezer-safe container for this. The instructions for reheating after freezing are pretty simple. Be sure to allow the pie to thaw overnight, in the fridge, before you reheat it.

Because of this, the crumbly top may be moist at first, so it’s best if you stick it in the oven on medium-low, never mind the microwave. This way you get a nice, even heating and the top can crisp up nicely once again.


Reheating apple crumble can be done in the oven or microwave, both with their pros and cons but sometimes you don’t have a choice. If you are at work it would be really hard to reheat them in an oven since most likely there isn’t one available or you don’t have the time to reheat them this way.
