Making sugar free meringue is so simple! These cookies are light as a feather, crispy and melt-in-the-mouth sweet. Even better, they are only 0.2g net carbs per cookie.
Keto meringue cookies have been on my to-try list for a while and I'm so glad I finally got around to making them.
People think that making meringues is difficult. It is not! In this post, I'm sharing all the details you need to know to get it just right.
This recipe can be used for French meringue pie, Eton mess or any keto recipes that require a meringue topping.
What are meringues?
Meringues are are a popular European dessert or candy made from just 2 ingredients: stiffly beaten egg whites and powdered sugar.
The air that is whipped into the egg whites makes the egg increase in volume and creates a foam. This foam is being stabilised by the icing sugar.
Meringues are baked in the oven like cookies. They are crisp on the outside and chewy on the inside.
There are 3 types of meringue that use different cooking methods: Swiss, Italian and French.
- French Meringue: The classic one. Sugar is beaten into the egg white until it dissolves. Light and airy.
- Swiss Meringue: The sugar and egg mixture is gently heated over a double boiler. Softer and denser, often used for pavlovas.
- Italian meringue: The sturdiest - soft and creamy. A cooked meringue that uses a sugar syrup. Must be made with a candy thermometer. Used for buttercream.
My sugar free meringue recipe follows the French meringue method. Of course, I am using a sugar free sweetener instead of sugar!
In fact, I am using a combination of 2 different sweeteners for best results.
🌟 Why You'll Love This Recipe
- Crispy texture - airy and light
- Sweet vanilla flavor
- Only 3 basic ingredients
- Naturally sugar-free, gluten-free and keto
- 0.2g net carbs per meringue cookie
You only need 3 basic ingredients:
- Egg whites - must be very fresh
- Inulin - a sweetener made from chicory root (read more about inulin). The additional benefit of inulin is that it acts like a stabilizing agent as well since it's high in fiber. This means you don't need to add cream of tartar.
- Powdered sweetener - I used an erythritol monk fruit sweetener blend
- Optional: vanilla extract.
I am not keen on the cooling taste of erythritol when it's overpowering. As regular meringues contain mainly egg whites and sugar, I originally wanted to avoid erythritol altogether.
In my first try, I used only inulin. Inulin (Amazon aff link) is gently sweet, high in fibre and does not have an aftertaste. The result was super-crisp and bright white. However, the texture was somewhat fibrous.
That's why I settled on using part inulin and part erythritol.
(This section contains step by step instructions and photos that show how to make this recipe. Find the recipe card with ingredient amounts and nutritional information at the bottom of the post.)
Let's get started with making keto friendly meringue cookies!
1.) Put 2 very fresh egg whites into a clean, dry glass or metal bowl. Whisk with an electric mixer until stiff peaks form.
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 parchment lined baking sheet. If you don't have a piping bag, simply spoon little cookie heaps onto the sheet!
4.) Bake for 15 minutes at 110 Celsius / 230 Fahrenheit on a low shelf. Then turn down the oven to 90 Celsius / 200 Fahrenheit continue to bake for around 45 more minutes.
5.) 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.
Tips for stiff egg whites
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 the mixing bowl is perfectly clean - no fat residue, no water droplets, no egg yolk
- mix using a traditional electric mixer (like the one in the recipe steps image, with metal whisks)
- 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 ¼ teaspoon of cream of tartar to your mix if you wish. I have not found it necessary when following the steps above.
I have made this recipe several times before I was happy with it. Here is what I learned:
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.
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. The air circulation helps the meringues to dry.
Sugar free meringue cookies are soft while they're warm. They crisp up as they cool down and should NOT stick to the baking paper.
You can make the recipe with only powdered erythritol - simply use 4.5 tablespoons of erythritol or an erythritol mix such as Swerve.
- Almond - Use ½ teaspoon of almond extract instead of the vanilla.
- Strawberry - Add 1-2 tablespoon of freeze dried strawberry powder.
- Peppermint - Add 1-2 drops peppermint extract.
- Lemon - Replace the vanilla extract with 1 teaspoon of lemon juice and add an additional teaspoon of lemon zest.
- Chocolate - Add 1-2 tablespoon cocoa powder and dip the bottoms of the meringues into melted sugar free chocolate!
- Use food colouring to add a touch of colour.
I have not yet experimented with making sugar free meringue using the Italian or Swiss method as described earlier. I imagine a liquid sugar free syrup could work quite well. I'll keep you posted!
A mix of erythritol or erythritol blends (monk fruit sweetener or stevia) and inulin yields the best result in terms of taste and texture. Using just erythritol also works, but the taste won't be as nice. Don't use allulose as it does not set hard and you'll end up with marshmallow.
This means that they need more drying time in the oven at 50 C / 120 F.
To crisp a soft meringue, simply pop them into the oven at 180C / 350 F for a few minutes.
It seems impossible to make sugar free meringue that stays completely white AND crispy. My best batch (see images) ended up ever so slightly beige on top. This does not affect the taste!
My sugar free meringue cookies contain only 0.2g net carbs per cookie.
Store at room temperature. Store in an airtight cookie jar for up to 3 weeks. They will soften up over time if kept outside because they attract the moisture in the air. For that reason, don't store them in the fridge either.
Store in the freezer. It's possible to freeze low carb meringue cookies! Freeze in an airtight container for up to 6 months. If you find they are soft after defrosting, crisp them in the oven as above.
