Keto Lemon Curd Blueberry Cheesecake

You should know that ever since I shared my easy keto lemon curd pie recipe, I have been a little obsessed with finding a way to use my keto lemon curd again. So, when I finally put together this recipe together it felt a little overdue.

The combination of blueberries and lemons are one of my favorite taste profiles. And in the summertime when crazy hot humid days are the norm here in Florida, it’s an especially welcomed choice.

I love it when a recipe turns out soooo good, that it seems hard to believe that it’s a low carb healthy option. That’s what happened with this easy keto cheesecake.

I needed another excuse to use my keto lemon curd topping. And since an abundance of blueberries and lemons seem to find my kitchen every summer, I thought to combine these two iconic flavors made perfect sense.  Let’s just say, I’m glad these were in season.

Because my recipe for keto lemon curd blueberry cheesecake was a complete hit with the family. My dining room roared with joyful sounds about how the tartness of the lemon curd went perfectly with the smooth texture of the cheesecake mousse.

With each spoonful, their voices grew louder until they made those lovely tarts disappear. Frankly, I can’t blame them for their overzealous reaction, since I was pretty thrilled with this keto cheesecake too.

It’s becoming a bit of a pattern for my children to hang out at the house most Sunday afternoons after church. Besides using this time to enjoy each other’s company, I take advantage of their eager palates to test a recipe.

Inevitably, this time also becomes a planning and dreaming session about what else we can believe God for as we expand the vision of Fittoserve.

How To Make A Keto Lemon Curd Blueberry Cheesecake 

Let me walk you through the steps and tools I used so that your keto lemon curd blueberry cheesecake turns out perfectly.  I promise you can do this.

I decided to make my low carb lemon curd cheesecake into smaller tarts because I was eager to try these Tortina tart molds. They are disposable 4″ x 1.3″ molds that made my tarts feel extra fancy and made cleanup a breeze. The recipe calls for 5 of these molds but you could opt to make one large 11-inch tart and use this pan instead.

How To Use A Double Boiler For Keto Lemon Curd

A bowl of keto lemon curd

If you’ve never made a keto lemon curd, then you must. I won’t take no for an answer. Don’t let the name curd intimidate you because this requires only four simple ingredients. All you need for this low carb lemon curd is egg yolks, sugar substitute, lemon juice and butter, and a few minutes of stove time.

I make my keto lemon curd over a double boiler just to be safe, but I’ve been known to skip this step. And as long as I keep the temperature low, the lemon curd has never separated for me. But if it’s your first time, take the extra precaution and use a double boiler.

Not sure what a double boiler is? It’s pretty simple really, you’re basically mixing your ingredients inside a bowl that is placed on top of a pan of simmering water. The bowl needs to be large enough to create a seal with the bottom pan. Just don’t let the water touch the bottom of the bowl so that it doesn’t overheat.

What’s great about using a double boiler to make a keto lemon curd, is that the temperature is much lower than attempting this feat indirect heat and therefore you don’t risk the ingredients getting stuck or burning. It’s a more controlled way of cooking.

Keto Cheesecake Mousse Layer

The cheesecake layer of this tart is light, airy, creamy, and dare I say flat-out dreamy. To achieve the perfect keto cheesecake mousse filling, mix room temperature cream cheese, sour cream, cold heavy whipping cream, sugar substitute, lemon juice, lemon extract and a little unflavored gelatin powder for stability.

The cheesecake mousse layer is so good that it can stand alone as a dessert. Do you see what I’ve done for you? I’ve created two recipes in one.

Keto Almond Shortbread Crust

You’ll only need your oven for 10 minutes for this recipe because only the crust needs to be baked. The cheesecake layer doesn’t need baking.

For the almond crust, you simply melt the butter and combine it with the almond flour, sugar substitute, lemon juice, and lemon zest. Then press the mixture to the bottom of the tart pan(s). No need to press the crust to the sides of the pan.

If you are in a rush you can opt to skip the baking altogether of the crust. Yup, that’s right. Remember almond flour is just crushed almonds so it doesn’t require cooking. This would make this keto lemon curd cheesecake a no-bake option.

I chose to bake my crust because I like the flavor that is produced as the butter browns and the almonds toast. It’s worth the extra 10-15 minutes in my book. I’ll leave the decision to bake the crust or not up to you.

Do you know who else enjoyed my keto lemon curd blueberry cheesecake? Our picky son Matthew. When Matthew declared that it was the best low carb dessert he’s tasted of mine, my heart leaped for joy.

You need to understand something about Matthew, for starters, he still doesn’t want anything to do with our keto lifestyle, plus he rarely gives food complements. The kid has always been an extremely picky eater and the reason I’ve been known to lose my cool in the kitchen. This momma ain’t perfect, so don’t look surprised.

Keto Desserts Everyone Will Enjoy

I’m not kidding when I say that our Matthew may one day become a professional food critic. He has a very sensitive(discerning) palate. All this means is that this momma doesn’t expect to be showered with his compliments. So whenever he pays me one,  I’m going to keep it close to my heart.

In stark contrast, I have Randy who’s always eager to test my recipes. And who rarely if ever has anything negative to say about them. I don’t know if hubby is afraid to voice his opinion since I am the one that cooks in this relationship, or if the man just really loves my food.

Our daughter Michelle, on the other hand, strikes the perfect balance between fawning over my recipes and sharing what she feels could enhance them. While Peter her hubby, stays in the same lane that Randy does. LOL.

So needless to say having all their opinions kinda gives me a true picture and helps balance things out for this keto food blogger.

I sure hope you give this recipe a try. Once you do, make sure you remember to tag us on Instagram and Facebook. It’s what keeps this girl encouraged to keep sharing and perfecting her recipes for you.

If there is one thing I particularly proud of sharing it’s how we combined our Christian faith with the keto diet.   

In case you don’t know, Randy and I came to the keto diet looking at it from a Christian perspective. As believers, we live our entire lives supported by God’s grace.

So when the Holy Spirit led us to combine our Christian faith and the keto diet, we did so in hopes of finding lasting transformation.

Randy had been a diabetic for over 15 years and he was dealing with the consequences of this disease. I was a survivor of the Guillan Barre Syndrome and was fighting fibromyalgia and chronic sciatica.

To say we needed God’s intervention is putting it mildly. When we followed the Holy Spirit’s prompting to we got on the path to real transformation. 

Knowing firsthand the benefits of this decision we have created a closed Christian group that is using the keto diet to transform their lives.  I love how supportive and encouraging this group of believers is. It’s exciting to see how people are transforming their lives by combining this lifestyle with the Christian faith. 

The testimonies coming out of our Fittoservegroup is what motivates us to continue to share what we’ve learned.
