The Ultimate Guide to Reheating Frozen Quiche

As quiche contains a couple of different ingredients, reheating it can become tricky. Due to the high egg content, reheated quiche can sometimes turn out watery, or the crust might become soggy.

If the quiche contains bacon, such as a quiche Lorraine, the bacon might become soggy in the microwave. It is important to know which ingredients are in your quiche when deciding how to reheat it.

How to Reheat Frozen Quiche in the Oven

Your quiche will taste fresh and as-new when reheated in the oven. The quiche would have initially been cooked in the oven, so it makes sense then that the oven would be the best option to bring back its great texture and flavor.

To reheat quiche in the oven:

  • Preheat the oven to 350 degrees Fahrenheit. 
  • Place the quiche into the oven, in an oven-safe dish (I personally use this quiche dish I found on Amazon), and leave it to reheat for 15 to 20 minutes if the quiche has been in the fridge, whereas a frozen quiche can be reheated in 30 to 35 minutes.

You need to be sure to cover the quiche with aluminum foil to prevent it from losing any moisture. When you take the quiche out of the oven, you should let it sit on the counter for 15 minutes, still covered with aluminum foil, before serving. 

Pros of Using the Oven

The oven is the preferred way to reheat quiche, it keeps the flavor of the filling and keeps it moist, but still helps to keep the crust flaky.

You can heat up a larger portion of quiche in the oven, compared to smaller microwaves. You are also able to reheat quiche from frozen in the oven, without having to leave it to thaw beforehand.

Cons of Using the Oven

The one con of using the oven is that you need to allow it to reheat before placing the quiche into the oven. This can take some time, but the wait is definitely worth it.

You also need to make sure that the quiche is covered with aluminum foil, to prevent it from drying out.

How to Reheat Frozen Quiche in the Microwave

The microwave is the best option to use if you want to reheat your quiche in next to no time at all. If you are taking some quiche to work, you don’t have to worry about finding an oven somewhere, you simply have to use the microwave in the office kitchen.

Using the microwave will not give you the same great results as when using the oven, but if done correctly, you can still enjoy some delicious quiche.

It is never really advised to reheat eggs in the microwave, as they turn out rubbery, but if you do it properly, you can avoid this when reheating quiche in the microwave.

You will need to defrost the quiche before placing it in the microwave. You can either do this by leaving it in the fridge to thaw overnight, or by using the defrost function on the microwave.

When this is done, place the quiche in the microwave at 50% power. You will need to set it at 50% to stop the eggs from overcooking and to keep them fluffy.

Place the quiche on a microwave-safe plate and leave it to warm in the microwave for 3 minutes.

Leave it to sit for a minute once it has been taken out of the microwave, for the heat to distribute evenly. If it needs some more reheating time, place it back into the microwave for 30 seconds until reheated.

Pros of Using a Microwave

The microwave is obviously one of the quickest ways to reheat frozen quiche.

Not only does it reheat the quiche quickly, but the defrost function on the microwave can thaw the quiche quickly for you as well. You will have a deliciously reheated quiche in a matter of minutes.

Cons of Using a Microwave

You run the risk of drying out the quiche and landing up with a soggy crust when using the microwave. You need to be sure to reheat the quiche on half power to ensure the eggs do not dry out and turn rubbery, and that you do not land up with a soggy crust.

How to Reheat Frozen Quiche in the Toaster

Using a toaster is possibly the least popular method of reheating quiche, and it only works with a firm quiche that will not crumble apart.

It gives a better reheating than that of the microwave, but you need to ensure that you keep an eye on the quiche to ensure that it does not burn.


To reheat quiche in the toaster, it needs to be at room temperature first. Leave it to thaw in the fridge overnight, or place it to defrost in the microwave.

When it is at room temperature, place the piece of quiche into the toaster for a few minutes, continuously checking the temperature until it is ready to be eaten.

Pros of Using a Toaster

The toaster, like the microwave, offers up a quick solution to reheating quiche. It takes a few minutes and you do not need to wait for the toaster to heat up.

If kept in the toaster for the right amount of time, the eggs will still be soft and the quiche will taste just as good as when first cooked.

Cons of Using a Toaster 

The biggest downside to using a toaster is that the quiche can burn quickly if left in for even 30 seconds too long. Keep a continuous check on the quiche while it is in the toaster, and turn it on to medium power if it allows for it.

Storing Quiche

How well you store your quiche will play a factor in how well it reheats. You can choose to store a whole quiche in the freezer, or individual slices to portion out for a few meals.

When the quiche has finished baking, leave it to cool down to room temperature. Try not to cover the quiche, as this could result in the crust becoming soggy.

Once the quiche has cooled down, wrap it with plastic wrap tightly, and then cover it with aluminum foil. You can either choose to cover the whole quiche this way or each slice individually.

It is really important to make sure the quiche has cooled down completely before wrapping it for freezing, as any additional heat can cause condensation which could cause it to become soggy.

Place the quiche in the freezer completely wrapped up. When freezing quiche, you should try not to add too many vegetables, and rather add in blanched or frozen vegetables which have been thawed and drained. This way they will remain firm and crisp when reheated.

Reheating Frozen Quiche

Quiche can be the perfect meal to cook ahead of time, and to freeze to enjoy at a later stage. Freezing quiche is fairly simple, you just need to ensure that it is protected from moisture and freezer burn.

When it is time to reheat the quiche, you can choose to do so in the oven, microwave, or even the toaster. The oven is the best method to use to reheat frozen quiche, and you can even place the quiche in the oven from frozen. However, if done right, all the above methods can reheat quiche deliciously.
