The croissant is a type of bread typical of the French bakery made with a flaky pastry; if you are here, you may know it is delicious, and if they have any filling, even better. So today, I will talk about how to store Croissants.
Due to the components of the croissant, you can only keep it for one day at room temperature. If you need to store it longer, you can refrigerate it for one week or freeze it for two months.
To know how to preserve the croissant, you must continue reading.
How to store croissants at room temperature
If you prepared or bought croissants and want to leave for breakfast or a snack the next day, you can store them as follows:
- Step 1: Wait for the croissant to cool.
If they are freshly made, you should wait for them to cool before storing them so that the internal steam does not clump them.
- Step 2: Wrap or pack each croissant.
To keep the croissant in that crunchy texture, wrap it with aluminum foil before putting it inside a paper or plastic bag. Or you can put them inside an airtight, without wrapping them.
- Step 3: Store the croissant in a dark place.
Place the croissants where the light does not stick, which is completely dry, and stay cool. In this way, the croissant can last a day at room temperature. 
After 24 hours, croissants will start to go bad, but if they only get a slightly sour taste, you can “revive” them by reheating them in the oven.
How to store croissants in the fridge
If you made or bought too many croissants, you should store them in the fridge to prevent them from becoming rancid and hardening.
- Step 1: Wait for the croissants to cool down.
If they are freshly made, wait for them to cool to room temperature before storing them so that the internal steam does not clump them down.
- Step 2: Cover each croissant.
For the croissant to maintain its texture, wrap each piece with plastic film. Then, put them inside an airtight container or bag to prevent them from absorbing moisture in their environment and the smell of other foods.
- Step 3: Enter the storage date.
Stick a dated label on the package or write the date directly on the bag. If you do not have a label, you can also write the date on some tape attached to the container or bag.
- Step 4: Store the croissants in the fridge.
Place the croissants near the door (avoid the coldest side) so you can keep croissants refrigerated for a week.
How to freeze croissants
You may be wondering, “Can croissant people be frozen?” Of course, you can, so do it from the following morning:
- Step 1: Wait for the croissants to cool down.
If they are freshly made, place the croissants on a rack to expel all the internal steam faster so it will not ruin the texture later.
- Step 2: Wrap each piece of croissant.
So that the croissant does not suffer frostbite, wrap each piece with plastic film and aluminum foil. Then, put the wrapped croissants in an airtight container or bag that resists the freezer.
- Step 3: Enter the storage date.
Stick a label with the storage date on the container or write it directly on the bag. You can also write down the date on a strip of tape attached to the container or bag in case it does not have a label.
- Step 4: Store the croissants in the freezer.
In this way, you can freeze croissants for two months. 
How to preserve stuffed croissants
Croissants can be filled just like any other type of bread, and preferably, you should eat them the same day you fill them, but if you have any leftovers, wrap them with plastic film and put them inside an airtight bag or container.
You can store stuffed croissants in the fridge, in the coldest part, for 2 to 4 days. You can also freeze them for 3 to 4 weeks, but in this case, be sure to use freezer-resistant containers and remember to set the storage date.
But before freezing them, check if you can freeze the filling. Usually, it would be best if you did not freeze creamy fillings with vegetables or fruits, but fillings with ham and cheese are ok.
To thaw the stuffed croissant, let it in the fridge overnight, then leave it for a while at room temperature, and finally, you can reheat it, as I will tell you in the next point, but its texture will not be the same.
How to reheat croissants
Reheating the croissant helps it to recover its flavor and consistency. Although it will not be as freshly made, it is better to do it before eating it.
Preheat the oven to about 180°C (360°F), then put the croissants in for 2 or 3 minutes. Remember to let the croissants at room temperature for 10 minutes or so.
If you have frozen it, you can let it in the fridge overnight or heat it frozen. You must remove the wraps and bake at 180°C (360°F) for 10 minutes. But with this method, there is a risk that the texture will change.
Croissants cannot be refrozen after being thawed or refrigerated, so thaw the right amount.
How to preserve the croissant dough
Another storage method is to store the croissant dough for those who like to prepare them at home but prefer to eat it fresh.
The answer is no if you are wondering if you can refrigerate the dough. Croissant dough has a high-fat content, and therefore it is better to keep it frozen so that it is stable since, in the fridge, it can ruin its consistency.
The best way to save it is as follows:
- Step 1: Assemble the croissants.
Do the entire process to make croissants until assembly, but do not bake them.
- Step 2: Freeze the raw croissants for two hours.
On a tray, place a layer of parchment or wax paper, then arrange the croissants side by side, but they are far enough apart to avoid sticking.
Cover the croissants with cling film and put the tray in the freezer. Freeze for two hours or until completely hard.
- Step 3: Bag the frozen raw croissants.
Once well frozen, transfer them to an airtight bag or container and resistant to the freezer.
- Step 4: Write down the storage date.
Put the date directly on the bag or container or stick a label.
- Step 5: Store raw croissants in the freezer.
You can keep the frozen croissant dough or raw croissants for about six months.
Preheat the oven to about 200°C, then bake for 30 or 40 minutes or until golden brown and crispy.
You can also freeze the dough without assembling the croissant, although later you will have to do it; leave it flattened, divide it into portions and wrap it with plastic film, then continue from step 3 of this method.
How do you know if the croissants spoiled?
You can determine if croissants are bad by checking the following:
- Taste: If they taste bad or are too rotten, do not eat them and get rid of them.
- Texture: If croissants are watery and viscous, they are no longer safe to eat.
- Smell: If they have a solid rancid or rotten smell, throw them away because they are wrong.
- Mold: When lint or green, black, or white spots begin to appear, they develop mold and should be thrown into the trash can immediately.
Why do croissants spoil?
Croissants are a type of bread; therefore, they carry yeast, and the components of this ingredient have to “age” if they are not stored in an environment that slows down or stops that process, so it does not last too long in at room temperature.
Humidity will make the croissant rubbery and promote the development and proliferation of different microorganisms harmful to health, such as mold.
One of the main threats to any bread and croissant is fungi, among which penicillium and aspergillus stand out, which develop thanks to the humidity.
Light and heat accelerate the deterioration of the bread, so when stored at room temperature overnight, the croissant should be kept isolated.
How long do croissants last?
|Croissants at room temperature||1 day|
|Croissants in the fridge (unfilled)||1 week|
|Frozen croissants (unfilled)||2 months|
|Croissants in the fridge (filled)||2 – 4 days|
|Croissant in the freezer (filled)||3 – 4 weeks|
|Frozen Croissant dough||6 months|
What is the best way to preserve croissants?
Croissant is best eaten freshly, as their flavor and consistency change over time. If you store the croissant at room temperature, it will barely last about 24 hours.
However, keeping croissants refrigerated is an alternative to consider, but they should be kept well insulated so that they do not absorb moisture or odor from other foods.
So, the best way to store the croissant, at least already baked, would be to freeze it because they will keep it for a long time.
But if you had to choose the best way to preserve the croissant, it would be to freeze it raw, so you will have a freshly made one whenever you want.
