Low Carb Lemon Bars

keto lemon bars - yum These keto lemon bars are a little on the tart side because as you become keto adapted, you don’t have the sweet tooth you once had. But if these keto lemon bars are too tart for you just back off on the lemon juice or add more sweetener to the lemon curd filling.

Coconut Flakes In The Shortbread Keto Crust

The buttery crust on these lemon bars has a little extra crunch from the coconut flakes. Don’t worry if you don’t like the taste of coconut. You’ll hardly notice any coconut flavor from the flakes. It’s just there for crunch and texture. You can always omit the coconut flakes if you despise coconut.

Fresh Lemon Juice For The Best Keto Lemon Bars

You can use store bought, bottled lemon juice in this recipe; however, using fresh squeezed lemon juice will provide the most flavor.

White Bubbles On The Keto Lemon Bars

If you notice some white bubbles on the top of your lemon bars, don’t worry - it’s completely normal. This is caused by air bubbles from the eggs in the keto recipe. It won’t affect the lemony flavor and you can cover it by dusting confectioner’s Swerve on top of the squares after they are cooled.

How To Get Lemon Bars Out Of The Pan For Serving

The easiest way to get any bar out of a baking dish is to first spray the pan with non-stick spray, like avocado oil spray. Then line the dish with parchment paper. Leave about two inches of parchment paper hanging out over the edges of the dish. This will serve as handles to easily lift the keto lemon bars out of the pan after baking.

Arrowroot Powder On The Keto Diet

I like to use arrowroot powder as a thickener in some of my keto recipes. It is a stronger thickening agent than flour so you need very little to thicken your recipes. Arrowroot powder is gluten free. It is the ideal thickener for paleo and grain free diets. It does contain carbohydrates; however, one tablespoon of arrowroot powder has 6.8 g net carbs. One tablespoon is enough to thicken an entire dish in most recipes. For this lemon bar recipe, that means 0.75 g carbs from arrowroot powder are going into each lemon square.

If you don’t have access to arrowroot powder, you can substitute with 1 teaspoon of xanthan gum.

I strive to find meals that your whole family can enjoy (kids and relatives too) while you are on your keto quest. You can still have your favorite foods on the keto diet, you just have to be creative with how you make them.
