How To Reheat Croissant?

This post may contain affiliate links. Please read my disclosure policy.

I always like to spoil myself with good and fresh pastries for my breakfast. I mean, it’s almost the only thing that keeps me sane during the rest of the day. Nothing beats some fresh out of the oven baked goodies, and don’t even get me started on the croissants. Definitely my personal favorite.

Unfortunately, I am always faced with the dilemma of getting these “fresh out of the oven croissants”. On most days I am left with stale croissants from the previous days, which used to be a problem for me.

Not anymore though. Because today, I am going to share with you How to reheat croissants in not one or two ways, but five different methods, in addition to the different ways of storing your croissants, and what to do with any stale croissants so that you won’t have any chance to spare even a bite of your croissants.

A note on my trials:

These are the best five conventional methods I tried with my croissants:

  • The microwave (covered with damp paper towel and another time without the paper towel)
  • The oven (covered and uncovered with aluminum foil)
  • Air fryer
  • The toaster
  • The stovetop (using butter)

I am going to number the different methods of reheating the croissants starting with the worst, in my opinion, finishing with the best. And in each one, I am going to state my opinion and any useful tip that might help you.
Now you get to choose the best way that suits you!

How to reheat croissant in air fryer?

How you reheat croissants in the Air fryer

Well, it’s definitely not my favorite method, mostly because it’s hard to really control the exact time to reheat your croissants without them drying out. That’s why I tried to lower the temperature a bit.

Steps of reheating:

  • Align your croissants on the Air fryer tray.
  • Put the tray in a preheated air fryer at 250F/120 C. Leave them to heat for 1-2 minutes.

My final opinion:

This method is not really recommended, as despite lowering the temperature enough, yet it still somehow dry out.

But don’t lose hope there are many other more successful methods.

How to reheat croissants in microwave?

The reason why I gave this method a somehow low rate isn’t because the croissants aren’t sufficiently reheated or anything, but rather because not everyone likes the end result, which is buttery, greasy, and soft croissants. A lot of people prefer the crusty on the outside, soft on the inside croissants. I can’t really blame them. The microwave method doesn’t really focus on the quality as much as the efficiency of reheating.

Steps of reheating:

  • Cover the plate containing the croissants with a damp paper towel.
  • Leave it in the microwave to heat for 10-15 seconds.
  • Take it out of the microwave and enjoy.

My final opinion:

Not everyone will like this method of reheating, that’s why you should consider this before trying it. Whether you would like the croissants to be greasy and buttery, baring in your mind the whole layers will be a bit mixed, or whether you like your croissants with the signature flaky layers. In both cases is microwave is a fast method of reheating your bakery, but after about 10 minutes it might be a bit dry, that’s why it must be eaten immediately.

How to reheat croissants in a toaster?

I definitely think it’s a good alternative to using the microwave to reheat your croissants. It’s really easy and takes no time.

Steps of reheating:

  • Using a bread knife, cut each croissant in half.
  • Toast each half for a minute or more, according to your preference, on a low setting toaster.
  • After it’s done, spread some butter, Nutella, Jam, or cheese on it and enjoy.

My final opinion:

The outcome is certainly more satisfying, at least for me. It results in a crispy on the outside, yet soft on the inside delicious croissants.

How to reheat croissants on the stovetop or in a sandwich press?

Don’t be discouraged by how unusual this may sound. It’s one of the best methods of reheating your leftover croissants. The results are chief’s kiss.

Steps of reheating:

  • Just like the toaster method, cut each croissant into two halves.
  • Align each half on the cut side facing the buttered-up pan.
  • Leave them for a few minutes till they turn crispy golden brown. Enjoy.

My final opinion:

Butter makes everything better. That’s why I LOVE this method. It’s not that healthy, of course, but it’s worth it I can assure you. You will have yourself one crusty and buttery side, and another soft and warm side. Make sure not to close the lid though, so that it doesn’t become soggy.
And of course, you can do this in the sandwich press as well.

How to reheat croissants in an oven/toaster oven?

How to reheat croissants in an oven-toaster oven

This is the best way to reheat croissants. Once you try it, you will know why. I am going to spoil it out for you!
It’s because the resulting bakery is exactly like the freshly baked ones!

Steps of reheating:

  • On a baking tray, align your croissants and cover them with foil.
  • Transfer the tray to a preheated oven at 300°F/150°C for 4-5 minutes in a conventional oven or 2-3 minutes in a toaster oven.
  • Uncover the foil for 2 minutes before taking it out of the oven.

My final opinion:

The perfect method for the perfect outcome. Flaky and layered croissants on the outside with soft and buttery inside just like the freshly baked ones. And you get to heat large batches at a time.

How to reheat ham and cheese croissants?

Just put them in a preheated oven at 300°F/150°C for 4-5 minutes and that’s it!
Don’t forget to cover the tray so that cheese can melt and turn into a lovely mushy mess.

How to reheat a chocolatine (chocolate croissant)?

Same as reheating the ham and cheese one. Using an oven. Set the temperature to 300°F/150°C and leave it for a few minutes.

What to do with stale croissants?

No croissant too far gone. In fact, it’s exactly like the stale bread, which means you can make Croissant French toast, bread pudding but using croissants. Sweet Croissant brittle filled with sugar, caramel all baked in the oven. Yum yum.

Don’t forget the croissant toasties, made with ham and cheese, or the fancier version of it, Croissant croque madame.

How to reheat incredibly stale croissants?

In this case, you will do a bit of mix between two methods of reheating. Where you will put your croissants in the microwave first for 5 seconds, then transfer them to the oven. The idea behind this is in the microwave itself, it helps soften the croissants a bit so that the oven doesn’t dry it out. The trick is in being quick in transferring the croissants from the microwave to the oven.

How to freeze croissants?

It’s actually pretty easy. The secret lies in freezing fresh pastries as soon as they reach room temperature after taking them out of the oven. All you need to do is to put them in a freezer bag and suck all the air using a straw, through leaving a small hole for the straw where you will suck the air from. Tightly close the bag, and that’s it. Leave it in the freezer for up to one month. Whenever you crave them, pull them out of the freezer and let them thaw for a few hours. It will be as good as the fresh ones.

How to reheat frozen croissants?

This is another way of heating your frozen croissants instead of waiting for them to thaw. Which is transferring them to a preheated oven at 350°F/180°C for 7-8 minutes after removing them from the freezer bag. You can also thaw the frozen croissants overnight and bake them for 4-5 minutes in a preheated oven at 300°F/150°C for the ultimate outcome.

Finally, I am going to show the recipe of the best way to reheat your croissants:
