I had to make a keto lemon meringue pie! Surely most of you loved a great lemon meringue back in the day so why should we miss out?

It is surprisingly easy to make this recipe. No fancy tricks needed. Just a few standard keto pantry items, eggs and lemons needed.

Let’s have a look at just how easy a great sugar free lemon meringue pie is made.

Keto Lemon Meringue Pie Ingredients

To make a keto lemon meringue pie you do need to make all the components yourself. Sadly, we don’t have keto friendly store bought pastry readily available or sugar free lemon curd.

However, in saying that both are very easy to make at home.

You will find our Keto Pie Crust Pastry is perfect for a sweet keto tart. And our sugar free lemon curd is one of our easiest and most popular recipes. Both are incredibly easy to make and taste so good no one will know they are sugar free.

Use the link provided in the recipe card to make ahead of time. Both can be made days in advance. Our Keto Pie Crust Recipe will also be available shortly on the Cookidoo.

Please take note of the tips for the ingredients and why they are used in the separate blog posts for these recipes.
I do try and make all of my keto recipes with as little ingredients as I can, but some are there for a reason and the same results are not achieved if you omit them.

HOT TIP One of my most often asked question regarding my keto pavlova recipe or meringues is; What sweetener do I use in a keto meringue? I have answered this one many times and yet some of you still go and use another and wonder why your meringue is chewy and soft. I absolutely recommend only powdered erythritol or a powdered erythritol/steviol blend. This will give you a perfect result.

How to Make Keto Meringue

For the meringue please use room temperature eggs and check the weight of the egg whites equals 240g. I use jumbo eggs and this measure gives you just enough to give a good volume of meringue on your keto pie.

Both cream of tartar and xanthan gum help to stabilise and trap air in the meringue and I do not recommend leaving them out.

Ensure your bowl is thoroughly cleaned with the vinegar and grease free. This is essential for a stiff meringue.

Whisk the eggs whites and cream of tartar until stiff peaks form. Add the sweetener one spoon at a time mixing well after each addition.

Add the xanthan gum, vanilla extract and vinegar and beat until the mixture is super thick and silky. If it is still light with small air bubbles keep mixing until it is super glossy.

Spoon the meringue onto the filled pie. Using a blow torch give it a lick of colour just before serving. I have included a baking method for those of you who do have a blow torch. Just ensure the oven is preheated before placing the pie into the oven. Keep a close eye on it as it will colour quickly.

How to Make Keto Meringue in the Thermomix

Making a keto meringue or pavlova in a Thermomix is the same basic principles.

Make sure the bowl is cleaned with a vinegar wash 5 sec/speed 8. Wipe dry with paper towel.

Insert the whisk attachment and add the egg whites and cream of tartar. Mix 3 min/37°C/speed 4/MC Off. You will see the egg whites get plenty of volume. With the lid off add the sweetener one spoonful at a time through the lid while the blades are rotating.

Add remaining ingredients and mix until super thick and glossy. Increase the time if needed but the mixture should be really glossy and taste amazing!

Notes

LEMON KETO MERINGUE PIE INGREDIENTS
Low Carb Lemon Pie Crust
Almond Flour Pie Crust – use almond flour or almond meal for the pie crust. The pastry is short and very easy to make. I use whey protein isolate in the pastry to keep the biscuit short and light. 
To make a crustless keto lemon meringue pie; spoon the lemon filling into individual ramekin or pie tins and top with whipped meringue.
LEMON FILLING
I recommend using xylitol or allulose as the choice of keto sweetener. Neither of these low carb sweeteners crystallise when chilled.
Lemon curd can re-crystalise in the fridge if you use erythritol
Use fresh free range egg yolks for a bright yellow lemon curd filling.
Use up to 1 tbsp lemon zest and half a cup of lemon juice to make this lemon pie extra citrusy!
Low Carb Lemon Meringue Pies are best served immediately.
For Thermomix® (or similar) owners erythritol for the meringue can be made into powder by mixing 10 sec/speed 10.
Shortcrust pastry can be made days ahead of time. The pastry can also be frozen.
