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!
Carbs in Traditional Custard Pie
According to Cronometer, a commercially prepared custard pie with one piece being 105 grams, or 1/6 of an 8 inch pie has 21.8 grams of total carbs and 12 grams of sugar.
Our Keto Lemon Custard Pie has 2 grams of total carbs which will not spike your blood glucose and will not cause sugar cravings either. It’s a win win!
KETO LEMON DESSERT RECIPES
I’m a lemon lover all the way so I have a few delicious 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. If you like single serving type keto recipes I have a recipe for mini lemon meringue pie and sugar-free lemon curd parfaits.
I’ve also got an 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!
USE A WATER BATH FOR SUGAR-FREE LEMON PIE
The first time I made this keto lemon pie, 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 gorgeous pie presents so beautifully for a party, especially Easter or Mother’s Day!
But you certainly don’t need a special holiday to enjoy this delicious lemon pie, it’s fantastic all through the year, weekend or weeknight. This delicious treat is a winner and a very easy recipe!
TIPS FOR SWAPPING INGREDIENTS
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 to replace coconut flour.
If you don’t have lemon stevia you can use plain stevia or even vanilla stevia. If you use plain stevia or vanilla I would recommend adding some lemon extract to compensate since the lemon stevia adds more lemon flavor.
If you don’t use stevia at all, you can use whatever sugar substitute sweetener you prefer that would equal about 1/2 -1 cup depending on how sweet you prefer your delicious pie. Here is my Sweetener Conversion Chart to help you find the right amount of other low-carb sweeteners to use!
I would not suggest swapping out the heavy cream, but if you do need it dairy free, possibly using coconut milk from the can would work, although I’ve not tried it.

It was very good tasting however, mine became very watery after sitting in the refrigerator on the bottom. It was more like a cheesecake than a custard. What could have gone wrong to make it watery?
If you used my coconut flour pie crust for the pie, it could be after sitting for some time in the fridge, the coconut flour absorbs the moisture in the custard.
I only have a 9 inch pie plate….can I use ramekins? and how many?
A 9 inch pie plate will work fine. There are 12 servings for the pie so if you want to keep the nutrition info the same you would need to use 12 ramekins.
Hi there
My calorie counter says a piece is 256 calories. How many calories is in your doubke cream please?
Thank you
Doesn’t the heaavy cream have sugar in it? If so, then it isn’t sugar free.
If making 6 inch pies instead of 9 inch would the baking time be reduced to compensate for smaller pie?
Yes I’d suggest reducing by 15-20 minutes.
What size pie plate?
Hi, I am from South Africa. I noticed alot of the recipes call for liquid stevia (usually in a certain flavour). Can i substitute with Xylitol?
You sure could although I’m not familiar with how sweet the Xylitol is compared to the stevia so I wouldn’t know how much you should use, maybe just start small and increase if you need more sweetness.
I Love Custards and this was fantastic. It was very simple to make. Perfect for family or guests. YUM! I didn’t have any Lemon Stevia, but used the regular Stevia drops and added a little extra zest.
Excellent, Happy to hear, thank you!
Just wanted to let you know own that I made this with 2 cups of full fat coconut milk (canned), and it worked! It was delicious!
Thanks for sharing!
is there supposed to be stevia besides lemon liquid stevia in this recipe?? I see in your notes you say if you don’t have stevia you can use any sweetner
looks yummy
I love pies. The fact that it is a tasty dessert without any additional sugar intake makes me happy.
