Making your own sugar free meringues is so simple! These lovely little keto cookies are light as a feather, crispy and melt-in-the-mouth sweet, just like a meringue should be. Enjoy them on their own or use the recipe for any low carb dessert that calls for meringue.
Sugar free meringues have been on my to-try list for a while and I’m so glad I finally got around to making them!
It took me a little trial and error to get it right. I am not keen on the cooling taste of erythritol when it’s overpowering. As meringues contain mainly egg whites and sugar, I originally wanted to avoid erythritol altogether.
In my first try, I chose inulin as a sweetener, which is made from chicory root. Inulin (Amazon aff link) is gently sweet, high in fibre and does not have an aftertaste at all. The result was super-crisp and bright white. However, the texture was somewhat fibrous and you all know I’m picky. A compromise was needed! That’s why I settled on using part inulin and part erythritol.
People tend to think that making meringues is difficult. Trust me, it isn’t – further on in the post I’m sharing ALL the details you need to know to get it just right.
The one thing that’s different about using erythritol instead of sugar in a meringue recipe is that the meringue cookies will turn a very light beige colour. I have made this recipe 4 times in total, using slightly different oven temperatures and lengths each time. Each time I ended up with a colour change (which does not affect the taste whatsoever!). If you should crack it and yours stay as white as freshly fallen snow, please share!!!!
How to make sugar free meringues – step by step:
1.) Put 2 very fresh egg whites into a clean, dry glass or metal bowl. Whisk with an electric mixer until stiff – but take your time! Start with a slow speed and increase the speed once the egg whites become foamy and begin to thicken.
2.) Mix the inulin and erythritol in a separate bowl. Add to the egg whites a spoonful at a time, while whisking on a high speed. Last, add the vanilla extract and continue whisking until combined.
3.) Fill into a piping bag and pipe cookie shapes onto a baking sheet lined with baking paper. If you don’t have a piping bag, simply spoon little cookie heaps onto the sheet!
Bake for 15 minutes at 110 Celsius / 230 Fahrenheit on a low shelf. Then turn down the oven to 90 Celsius / 200 F continue to bake for around 45 more minutes. CHECK THE COOKIES REGULARLY to make sure they don’t turn brown!!! Then turn off the oven and leave the meringues inside for at least another hour so they can dry out.
How to get stiff egg whites – every time
I used to have a Huuuuuge problem turning egg whites into cloudy peaks until I did some research. Your egg whites will be stiff without fail if you
- use extra fresh eggs
- use a glass or a metal mixing bowl. Plastic does not work.
- make sure said mixing bowl is perfectly clean – no fat residue, no water droplets
- mix using a traditional electric mixer (like the one in the recipe steps image, with metal whisks)
- don’t try this recipe with a hand whisk. You’ll never get the stiff peaks you’re after
- take your time and mix slowly first. Then increase the speed once the eggs are frothy and are starting to firm up. If you mix at a high speed right from the beginning, you’ll create large air bubbles with no staying power and your meringues will deflate.
Some meringue recipes recommend using cream of tartar to increase the stiffness of egg whites. You can add 1/4 teaspoon of cream of tartar to your mix if you wish. I have not found it necessary when following the steps above.
Personally, I have not found any benefit in using room temperature eggs over eggs that are straight from the fridge.
Keto meringues recipe tips
I have made this recipe several times before I was happy with it. Here is what I learned:
It seems impossible to make sugar free meringues that stay completely white AND are crispy. My best batch (see images) ended up ever so slightly beige on top. This does not affect the taste!
The oven time will depend on the size of the meringues (and on your oven!!). My meringues were only about 1 inch in diameter. Larger meringues will need longer than small ones. ALWAYS Keep a close eye on them and if they brown, remove them from the oven. Turn the oven on the lowest setting (mine is 50 C / 120 F), wait for the oven to cool a little, then return the meringues into the oven and leave for a couple of hours. If you have a fan oven, use the fan setting. I think the air circulation helps the meringues to dry.
The meringues will be soft while they’re warm. They crisp up as they cool down and should NOT stick to the baking paper. If they do, they need more drying time at 50C / 120 F.
You can make the recipe with only powdered erythritol – simply use 4.5 tablespoons of erythritol or an erythritol mix such as Swerve.
How about almond meringues? Simply use 1/2 teaspoon of almond extract instead of the vanilla.
Or lemon meringues? You can replace the vanilla extract with 1 teaspoon of lemon juice and add an additional teaspoon of lemon zest to the mix.
Chocolate fans – try dipping the bottoms of the meringues into melted sugar free or dark chocolate (minimum 85% cocoa solids)!
Store your meringues in an airtight cookie jar. They will soften up over time if kept outside because they attract the moisture in the air. If you want to crisp them up again, simply pop them in the oven at 180C / 350 F for a few minutes.
