Are Classic Lemon Bars Keto?

Therefore this is not diabetic-friendly unless you adapt the recipe.

Time to enjoy a lemon ow carb recipe and welcome summer with no guilt!

How To Make Keto Lemon Bars

It’s very easy to make keto-friendly lemon bars you first need to make a low-carb shortbread biscuit using low-carb flours and keto sweeteners.

Then, you need to prepare a sugar-free lemon curd to spread on top of the shortbread base and bake the entire dessert until set.

Finally refrigerate, slice, and serve.

Ingredients

For the low-carb almond crust, you need:

• Eggs – Prefer free-range organic eggs for the best taste. Eggs are keto-friendly ingredients.
• Blanched Almond Flour – use ultra-fine almond flour and avoid almond meal that is coarse and dark in color. It makes gritty shortbread.
• Low-Carb Granulated Sweetener, like erythritol or allulose.
• Vanilla Extract
• Melted Butter or melted coconut oil for a dairy-free option.
• Pinch of Sea Salt

For the low-carb lemon curd you need:

• Fresh Lemons– squeezed to get the lemon juice and lemon zest
• Melted butter or melted coconut oil
• Eggs
• Almond Flour

Preparing The Shortbread

Preheat the oven to 350°F (180°C).

First, line an 8-inch x 8-inch square pan with parchment paper.

Make sure there’s some parchment paper overhanging on the sides. It makes it easier to remove the low-carb lemon bar from the pan later.

Spray oil over the pan to prevent the crust from sticking to it.

Next, in a large mixing bowl, combine all the shortbread crust ingredients: almond flour, egg, melted butter, vanilla extract, sweetener, and salt.

The batter should look crumbly but not dry either.

You should be able to stick ingredients together if squeezed in your hand. If not add a little bit more melted butter or coconut oil.

Baking The Shortbread

Press the shortbread biscuit at the bottom of the prepared pan to form an even layer. Use the back of a spoon or silicone spatula to smooth the layer and press it down easily.

Prick the biscuit with a fork to prevent it from puffing in the oven.

Bake in the center rack of the preheated oven at 350°F (180°C) until the crust is golden brown – about 15 minutes.

Making Lemon Curd

Meanwhile, prepare the lemon curd. In a mixing bowl, beat eggs with melted butter and lemon juice.

You don’t have to use an electric beater, use a hand whisk and beat until just combined.

Then, stir in almond flour. Set aside at room temperature until the crust is baked.

Remove the pan from the oven and immediately pour the filling on top of the baked crust.

Bake again until the curd is set. Watch it carefully and remove the pan from the oven when it’s set on top but still a bit jiggly in the middle to keep the dessert moist.

Cool completely in the pan for one hour then place the pan for 3 hours in the fridge before slicing.

This technique ensures the slice is firm and easy to slice without breaking apart.

Release the bar from the pan using the hanging part of parchment paper.

Pull out the gluten-free lemon bar from the pan and place the bar on a chopping board and cut it into 16 squares.

Serving

These keto lemon bars are delicious served with some topping like:

• Unsweetened Whipped Cream
• Freshly Grated Lemon Zest
• Coconut Yogurt
• Thin Slices of Lemon
• Dust of Sugar-Free Powdered Sweetener like powdered erythritol or powdered allulose.

Storage

These almond flour lemon bars can be stored in an airtight box in the fridge for up to 4 days.

You can also freeze lemon bars, preferably in zip-lock bags or airtight containers to keep the keto lemon bars recipe fresh and moist.

Thaw in the fridge the day before serving.

Frequently Asked Questions

Can I Replace The Almond Flour With Coconut Flour?

You can’t use coconut flour or it will be a very different ratio since coconut flour contains four times fiber.

Can I Use Packaged Lemon Juice?

You can but the flavor of the dessert won’t be as flavorsome and you will miss some lemon flavor.

You can balance that by adding 1 teaspoon of natural lemon extract to the custard.

Can I Use Almond Meal Instead Of Almond Flour?

You can but the texture won’t be the same. The crust and filling will be slightly grainy and darker in color.

How Many Carbs Are In Keto Lemon Bars?

These Keto Lemon Bars have only 2.5 grams of net carbs per serving.
