Making a frittata is always fun – and they make a great breakfast-on-the-go.

But what’s the best way to reheat a frittata so the egg stays light and fluffy instead of becoming rubbery?

I did an experiment to find out.

How you store the frittata is important too, so I’ve also included some tips on keeping it fresh.

In a rush? Here’s the short answer:

The best way to reheat a frittata is in a skillet. Heat some oil or butter on medium heat. Add the frittata when the pan is hot. Reheat the frittata for 2-3 minutes, then flip it over and repeat for a further 2 minutes. If it’s still not hot enough, flip it and repeat before serving.

A note on my experiment

I looked in my veg draw on Saturday morning and realized I needed to use most of it PRONTO.

And what’s the best thing to make with nearly gone off veg?

A frittata!

Once the frittata was made (and I’d taste-tested it), I put it in the fridge.

The following day, I tried out five different methods to reheat the frittata:

In the oven/toaster oven (worked well but a bit slow)
In the microwave (quick and convenient)
In a skillet (my favorite method)
In an air fryer (quick and gives a crispy texture)
In a toaster (see below)

The skillet gave the tastiest results and would be my go-to method in the future.

The oven and the air fryer are great too and mean less washing up!

I wasn’t a massive fan of the microwave, but if you’re really pressed for time, then it’s the best option.

Reheating frittata in the oven/toaster oven

Lightly grease an oven-safe dish and preheat the oven to 350°F (180°C). Place the frittata in the dish and cover it with foil. Heat the frittata for 10 minutes or until heated through. Remove the foil for the last few minutes of heating to crisp the top.

Times will vary depending on the size of your frittata and the type of oven you’re using.

I was heating a slice of frittata in a small oven.

How to reheat frittata in the oven/toaster oven:

Lightly grease an oven-safe dish or baking tray (ignore this step if your frittata is already in an oven-safe dish).
Preheat your oven to 350°F (180°C).
Cover the frittata with foil and heat for 10 minutes. Times will vary, so always check your frittata is hot all the way through before serving it.

Whole frittatas and frozen frittata will take longer than 10 minutes, while if you’re using a toaster oven, the process will be quicker.

The foil helps trap moisture and make sure the frittata doesn’t dry out.

Feel free to skip the foil if your frittata is a bit soggy.

Tip: sprinkle some cheese over the top of the frittata and wait for it to melt to add some delicious cheesy goodness!

My verdict

My frittata turned out great – it wasn’t overcooked, and the eggs still had a fluffy texture. The cheese took my breakfast to the next level.

The only downside is that it can be pretty slow if you’re using a conventional oven, especially for just a slice.

Reheating frittata in the microwave

Place a slice of frittata on a microwave-safe plate and cover it with a damp paper towel. Microwave on 50% power in 30-second intervals until it is hot. Remove the slice from the microwave and allow it to rest for 1 minute before serving.

How to reheat frittata in the microwave:

Place a slice of frittata on a microwave-safe plate.
Cover the frittata with a damp paper towel.
Set your microwave to 50% power and heat the frittata for 30 seconds at a time.
Remove the slice from the microwave and allow it to rest for 1 minute before serving.

Eggs are very susceptible to turning rubbery in the microwave, which is why I recommend using 50% power.

The lower power gives you more control over the heating process and means the eggs are less likely to overcook.

I also sometimes line the plate with a dry paper towel to soak up any excess liquid that leaks out of the frittata (more likely if you’ve used watery vegetables).

My verdict

The microwave doesn’t give the best results in terms of texture, but the convenience and speed make this a very attractive method.

Reheating frittata in a skillet

Heat some oil or butter in a skillet on medium heat. Add the frittata when the pan is hot. Heat the frittata for 2-3 minutes, then flip it over and repeat the process for a further 2 minutes. If they’re still not hot enough, then flip them and repeat before removing them from the pan.

How to reheat frittata in a skillet:

Heat some oil or butter in a skillet on medium heat.
Add the frittata to the hot pan, and heat it for 2-3 minutes.
Flip the frittata and heat the other side for a further 2 minutes.
Keep heating and flipping until the frittata is piping hot.

As the frittata is heating, periodically check it to make sure it’s not starting to burn.

If it’s getting too well-done and the middle isn’t warm yet, turn the heat down.

I prefer to use butter in the pan rather than oil because I like the flavor better.

My verdict

This was my favorite method.

The frittata tasted great and I liked the browned texture on the outside.

The downside of using a skillet is the extra washing up!

Reheating frittata in an air fryer

To reheat frittata in an air fryer, set it to 300°F (150°C). Arrange slices of frittata in the basket, leaving a gap between each piece. Heat the frittata slices for 3-4 minutes. Check that they are hot in the middle and heat for longer if needed.

How to reheat frittata in an air fryer:

Preheat the air fryer to 300°F (150°C).
Place your frittata in the basket, leaving gaps between any slices.
Heat the frittata slices for 3-4 minutes before checking if it’s hot all the way through.
Heat for a further 1-2 minutes before checking again.
Continue until hot all the way through.

I recommend cutting smaller slices when you’re heating in the air fryer.

This ensures the frittata heats up in the middle before the edges start to dry out or burn.

If you want a crispy outside on the frittata, brush it with some butter before putting it in the air fryer.

My verdict

This method works well if you are in a rush and want a good, quick method.

The egg was slightly overcooked on the outside for my liking, but the frittata still tasted nice.

Reheating a frittata in a toaster

To reheat your frittata in a toaster, make a makeshift toastie pocket using a cut piece of parchment paper. Wrap the parchment paper around the frittata and gently place it in the toaster. Reheating a frittata in this way will take 1-2 minutes.

This is a really quick and easy method. Why didn’t anyone think of this sooner?!

What can you do with leftover frittata?

If you want to try something different, then you can breathe new life into your frittata by turning it into:

Gourmet sandwiches… a slice of frittata placed between two slices of bread and some cheese. Lunch heaven!
Egg fried rice. Shred the frittata and stir it into your fried rice near the end. An excellent way to sneak some extra veggies in.
A salad. Boiled eggs are a big thing in salads, so why not frittata too?
A breakfast burrito. A thin frittata makes the perfect addition to a breakfast burrito. Much less messy to eat than scrambled eggs.

How to store frittata

The best way to store a frittata is in an airtight container in the fridge. The frittata will last 3-4 days. A good tip is to line your container with a paper towel to soak up any excess liquid that leaks out of the frittata. If you have several layers, separate them with more paper towel or some parchment paper.

If you want to have something that’s easy to grab out of the fridge in the morning, you can also wrap individual slices of frittata in plastic wrap.

Can you freeze frittata?

Frittatas freeze well for 1-2 months. I’ve found it’s best to be picky with the fillings if you plan to freeze your frittata. Watery vegetables like spinach, tomatoes, or zucchini don’t survive in the freezer as well as things like potatoes, peppers, or meat.

How to freeze frittata:

Portion out the frittata and chill it in the fridge until cold (this helps it freeze quickly).
Line a baking tray with parchment paper and place the frittata on top, separating slices.
Place the frittata in the freezer for 1-2 hours (this is known as flash freezing).
Place the frozen slices in freezer bags and remove as much air as possible before sealing.
Label and date the bag before putting it back in the freezer.

Alternate options:

Wrap the frittata in a layer of plastic wrap followed by foil (good for whole frittatas).
Place frittata slices straight into a freezer bag and separate them with parchment paper (instead of flash freezing).

The frittata must be allowed to cool to at least room temperature before freezing because otherwise, the condensation will turn to ice in the freezer and ruin the texture of the egg.

I like the flash-freezing method because it makes it easy to just grab a slice of frittata and go.

Remove the air from the freezer bag by dunking it in a bowl of water.

The water pressure will force the air out, and you can seal the bag. You can also suck it out with a straw.

The less air in the bag, the less chance there is of the frittata developing freezer burn.

How to reheat frozen frittata

You can thaw your frittata in the fridge overnight or reheat it straight from frozen in the oven or the microwave. The oven is better because the microwave can leave the eggs a little rubbery. Preheat the oven to 350°F (180°C) and heat the frittata for around 20 minutes (less in a toaster oven).
