This Beautiful Sugar Free Lemon Custard Pie is Keto, Gluten Free, Grain Free and Low Carb and makes a beautiful stunning presentation for a party! Read my helpful tips below to make the perfect custard pie!

SUGAR FREE CUSTARD PIE

This amazing lemony custard pie actually forms its own crust. It's light and refreshing for a spring or summer dessert. With just a few simple ingredients you can whip this beauty up in no time for a special occasion or just a weeknight treat! Just 1 net carb per slice! 

If you're a regular follower around here, you know I love custards. Anything creamy and I'm ready to dive in. I've adapted my Coconut Custard Pie and my Crock Pot Blueberry Lemon Custard Pie to make this easy pie that is super satisfying. If you prefer individual serving desserts for easy portion control, my easy egg custard or my slow cooker maple custard would be right for you. But for those who really want a comforting custard with a delicious crust, try these personal egg custard tarts! 

KETO LEMON RECIPES

I'm a lemon lover all the way so I have a few recipes besides this one that might tickle your fancy to make. If you don't want a large pie like this in the house perhaps my Lemon Mug Cake would be best as it's just a single serving.  I've also got a, easy creamy, lemon cheesecake mousse you might love! Lemon Cheesecake Truffles for a bite sized treat! My Blueberry Lemon Custard Cake is made in the slow cooker for easy convenience! 

WHY USE A WATER BATH

The first time I made this I didn't use a water bath to bake and that was a mistake. The entire pie cooked beautifully around the edges, but the center was mush and uncooked. So the next time I made this, I made sure it went into a water bath so it would be perfectly cooked without the outer edges of the pie getting dried out.

Since the 8 inch pie dish didn't fit into a 9 by 13 baking dish, I opted for a turkey roasting pan and it fit perfectly. Lesson here is, don't forgo that step of a water bath, it's important!

KETO TOPPINGS FOR CUSTARD PIE

Some simple fresh raspberries, blueberries or blackberries would be just enough to top this custard pie. If you want to get a little more decadent add some sugar free whipped cream . You can also top this custard pie with a dairy free whipped cream if you prefer. 

This keto custard pie presents so beautifully for a party, especially Mother's Day! But you certainly don't need a special holiday to enjoy this custard, it's fantastic all through the year, weekend or weeknight, this is a winner!

TIPS FOR SWAPPING INGREDIENTS

Brenda's Notes;

• No coconut flavor is evident using the coconut flour, but if you really are opposed to using it, try some almond flour instead. You will need double the amount using fine almond flour for coconut flour.
• If you don't have lemon stevia you can use plain stevia or even vanilla stevia.
• If you don't use stevia at all, you can use whatever sweetener you prefer that would equal about ½ -1 cup depending on how sweet you prefer your pie. Here is my Sweetener Conversion Chart to help you find the right amount of other sweetener options to use! 
• I would not suggest swapping out the heavy cream, but if you do need it dairy free, possibly using coconut cream from the can would work, although I've not tried it.

Enjoy!
