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.

    Another really tasty attempt, thanks Megan! The only thing that happened this time is my nice glossy meringue turned into something a bit crumbly, and I’m not sure what happened, other than I set it sit for about 15-20 min while waiting for the crust to cool. It still tastes delicious but I miss the gloss! x

    1. Megan Mad Creations Hub

      Hi Tonya, that sounds a bit weird. What kind of sweetener did you use (and brand)?

    Superb! The pastry is so close to normal pasty. Not enough pastry, though (the pastry recipe is for a 22cm pie tin, but the lemon meringue pie recipe uses a 32cm pie tin). Love the lemon curd and the meringue is perfect. Thank you for this wonderful recipe.

      I am so happy you enjoyed it Patricia

    When you mention vinegar is that malt, white, apple cider or other?

    Think I have missed it somewhere.

    1. Megan Mad Creations Hub

      It is just white vinegar sorry

    Just wondering how it should be stored, I made tarts Thanks

      Haha!

    I’m about to make this meringue topping for the lemon curd. I’ve only put 3 egg whites in so far and my grams are 217. Not sure how this works out. I’ll do the half recipe as planned and see how it goes. Appreciate your help Megan.

    1. Megan Mad Creations Hub

      Hi Trish, sorry I am not sure what you mean?

      1. Justin

        I think (please correct me if I’m wrong) Trish Warnes was in the process of adding six egg whites to achieve 240g weight as shown in the recipe, but after only three egg whites (therefore half the egg whites), she was up to 217g, meaning should she add another egg white and go over the 240g weight or …? I would assume you would aim for the 240g rather than worry about the number of egg whites, but for clarity perhaps you could confirm.

      2. Megan Mad Creations Hub

        The weight of the egg whites is preference in this recipe. The average egg white weighs around 30 grams. If someone was weighing an egg white at more than double the weight they must have been huge eggs.

    OMG! This reminds me of the lemon meringue pies that I used to eat as a kid! Bloody delicious and super easy to put together. Time saver tip; definitely make and bake your pastry pie shell the day before. Who would even know that it is a keto recipe? An absolute winner for a dessert novice like me. Thank you!

      Woohoo! Glad you enjoyed it Helen!
