I have always been a fan of all types of cheesecakes. However, what makes this keto cheesecake extra special is that it’s topped with keto lemon curd.

Bravenly premium supplements

The generous topping of low-carb lemon curd is what makes an otherwise delicious keto cheesecake into something amazing.

If you’re a lemon lover, you’re in for a real treat!

When I tested this keto lemon cheesecake on my family, they went a bit wild over it. They kept returning for more until I had to put my mom’s hat on and remind them to save some for later.

It’s a keto dessert made with simple ingredients that features a tart lemon curd topping that makes this low carb cheesecake flat-out irresistible!

Don’t you just love it when a recipe is that well-received? 

That said, I will say that this recipe has a few extra steps over my usual offerings. But I will walk you through the recipe as best I can to ensure you get the same results I did.

If you are not one to make cheesecakes often do not be intimidated. There may be a few steps involved because of the different components, but none of these steps are challenging. 

Keto Lemon Curd Cheesecake Ingredients

This low-carb lemon cheesecake features a simple almond flour crust that will fool your taste buds into thinking it’s a graham cracker crust.

Plus, the crust ingredients consist of only almond flour, sweetener, and melted butter making it a breeze to make.

The velvety, smooth cheesecake is further enhanced with a little lemon extract. Then it’s topped with a decadent, tangy lemon curd that is perfect for when you need a keto-friendly lemon dessert.

To make this keto lemon curd cheesecake, you’ll need the following basic ingredients:

How To Make A Keto Lemon Curd Cheesecake

Before you begin to make this recipe, it’s vital that you allow your eggs and cream cheese to come to room temperature.

By taking this extra step, you ensure that the cheesecake batter mixes evenly. So don’t take any shortcuts. 

What’s also vital is that you use the correct type of cream cheese. So make sure you are ONLY using full-fat cream cheese when making a keto cheesecake. And that it’s not a cream cheese that has been whipped for airiness.

Although I made my keto cheesecake in a stand-up mixer, you could also make the cheesecake base in a high-powered blender.

Because I own a Kitchen Aid mixer, it combines my ingredients perfectly, but if you don’t have one, use the blender. Doing so will make the process easier and save you some time.

Just remember that you want your cheesecake batter to be well-incorporated and creamy.

This is why you must blend the batter long enough until you don’t see any lumps, but don’t overmix as it can cause your cheesecake to collapse when it’s being baked.

Because what you don’t want is to cut into your cheesecake and find flecks of cream cheese that have not been mixed into the batter, got it? 

Since I wanted to highlight the flavor of lemon in this recipe, I added lemon extract instead of the traditional vanilla that most cheesecakes call for.

This little bit of extract allowed the flavor of lemon to shine brightly.

Best Sugar Substitute Options

When it comes to choosing your sugar substitute for this keto lemon cheesecake, I have several for you to choose from.

My go-to choice is Lakanto Monk Fruit because the texture is spot on, and there is barely any aftertaste. It is a monk fruit and erythritol blend.

Lakanto Monk Fruit gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. It’s why it’s a great all-natural sugar substitute and has zero calories and zero glycemic index.

I’m also partial to Swerve an erythritol blend. Unlike other natural sweeteners like stevia, it has no bitter aftertaste and measures like sugar.

It’s also a sugar substitute that browns and caramelizes just like sugar. Swerve is made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives, or flavors.

You could also use the stevia and erythritol-based brand Pyure for this low-carb lemon cheesecake.

But keep in mind, if using Pyure, you will want to use 1/2 the amount called for in this recipe since it’s much sweeter.

Lastly, if you can’t easily find a more natural sugar substitute, you can also use Splenda successfully.

Keto-Friendly Cheesecake Crust

You’ll be making a gluten-free crust by using almond flour. It’s essential to make the crust for your cheesecake first since it will be baked before you add the cheesecake batter.

I make my crust with melted butter, similar to how I made my graham cracker crust before I went keto. 

To make this cheesecake crust, you must add melted butter to a mixture of almond flour, salt, and sugar substitute.

Once you combine the mixture, press the crust to the bottom of the pan, a lightly greased 9-inch springform pan.  

Then simply bake the crust in a preheated 350-degree oven for about 15-20 minutes. Or until the crust firms up and it’s lightly browned around the edges. 

How To Make A Bain-Marie For A Low-Carb Lemon Cheesecake

Most cheesecake recipes recommend the use of a bain-marie. Although that’s not always the case with my cheesecake recipes, I recommend you do so for this one. It ensures you have a creamier cheesecake.

If you’re wondering what a bain-marie is, it’s a French technical cooking term that refers to the process of using a hot water bath. It allows for an even cooking environment. 

There is a crucial step you need to do before adding your cheesecake to the bain-marie.  It’s that you completely cover the bottom and sides of your spring form pan in heavy-duty foil.

Otherwise, your cheesecake will end up a soggy mess. This is no bueno. 

To ensure you are doing this correctly, cover the springform pan with foil at least 3/4 up the sides of the pan. This will ensure that no water seeps into the cheesecake while baking.

If you do not have heavy-duty foil, use two pieces of regular tin foil stacked together that have been joined by folding all four edges together.

Then make a bain-marie by placing a large enough roasting pan in your preheated oven and adding your prepared 9-inch springform pan into the roasting pan.

Lastly, pour enough boiling water into the roasting pan to come up about 1/2 way up the cheesecake.

As you can see, it’s important to properly cover your cheesecake bottom and sides. So take your time when adding your foil, and make sure it has a tight seal. 

Make sure when you are baking the cheesecake; you resist the urge to open the door. Peeking will produce cracks on the surface of your cheesecake, so don’t.

Chilling Your Keto Lemon Cheesecake

I find that not enough cheesecake recipes explain the importance of allowing your sugar-free cheesecake to fully cool before enjoying it. But it’s a necessary step that should not be ignored. 

I feel that the texture and flavor of cheesecake are further enhanced when it’s allowed to chill for a minimum of 12 hours. I always did it when I used to make regular cheesecake, and it’s still the case when I make a low-carb cheesecake.

I get that’s a long time, but I promise you it’s worth the wait. Your taste buds will be rewarded for your patience.

Once you bake your keto cheesecake, allow it to cool completely on the kitchen counter for about an hour.  Then wrap it with cling wrap and place it in the refrigerator for 12 hours or overnight. 

This means you are looking at a minimum of 13 hours of waiting you need to factor in when making this recipe.

I assure you that properly chilling your cheesecake makes all the difference in the world.  If you want that velvety texture that only good cheesecake has, you’ll need to allow the cheesecake to sit in your fridge and do its magic.

This also allows for the flavor to mature and fully develop. You’re going to have to trust me, but it’s what needs to happen to get a perfect keto cheesecake every time. 

Keto Lemon Curd Recipe

A bowl of keto lemon curd

Without a doubt, the highlight of this cheesecake is the sugar-free lemon curd topping. If this is your first time making lemon curd, you’re in for a real tangy treat. 

Nothing compares to homemade lemon curd. You’ll be thrilled that you took the leap and tried your hand at making it.

That being said, the number one tip is to use ONLY fresh lemon juice. The stuff in the bottle just does not cut it.

The bright sunny color of this low-carb topping is sure to bring you a smile. It gets its vibrant yellow color thanks to the egg yolks, lemon zest, and freshly squeezed lemon.

But besides its cheery color, curd has the perfect blend of tangy, sweet, and creaminess.

What’s more, it’s relatively straightforward to make homemade lemon curd. Trust me, once you learn, you’ll want to make it often.

To make your keto lemon curd, you’ll need to use a double-boiler. I make my double boiler by placing a large glass mixing bowl over a pot of simmering water. 

Just make sure you do not allow the bowl to touch the hot water. What you want is hot steam to cook your curd evenly.

Once you’ve assembled your double boiler, you can quickly whisk it up. You will start by adding your butter to the bowl and allowing it to melt gently.

Then after the butter is fully melted and allowed to cool slightly, you’ll mix in your room-temperature egg yolks one at a time.

After you’ve whisked all the yolks into the butter, then add your sugar-free sweetener of choice, lemon juice, lemon extract, lemon zest, and a little bit of sea salt. 

Tips For Making A Great Keto Lemon Curd

Keep your eye on your lemon curd by constantly mixing it. Now’s not the time to step away from your stove. Ensure you continue to whisk your ingredients until the lemon curd fully thickens.

This won’t take very long because the egg yolks emulsify rather quickly. 

After your keto curd has fully thickened, you’ll need to place the curd through a fine-meshed colander. This step is essential to easily remove the grated zest and ensure it has a velvety smooth texture.

Then, place your lemon curd in a bowl and cover it with cling wrap. You will need to allow the plastic wrap to touch the curd’s surface to prevent a hard film from forming as it chills in the refrigerator. 

Topping Your Keto Cheesecake With Lemon Curd

The next day after your cheesecake has thoroughly chilled, you can add the lemon curd to your cheesecake. The nutritional facts reflect that I added the total amount of lemon curd to the cheesecake.

Because it’s so delicious, people(insert happy dance).

However, you may opt to use less and reserve the rest of the curd to enjoy ALL BY ITSELF.

But this girl wanted a generous topping, and frankly, I will bet you will too. 

Then it’s just a matter of serving or topping with your favorite seasonal fresh berries and even a few lemon slices. 

How To Slice And Store Your Keto Cheesecake

Slicing cheesecake can be a little tricky and messy. I avoid this by dipping my sharp knife in hot water and then wiping it clean before each and every cut. 

You’ll need to keep your cheesecake leftovers refrigerated. For the curd not to form a crust on the cheesecake, here again, you will need to allow the cling wrap to touch the topping.

Keto Lemon Curd Cheesecake

Yield: 10
Prep Time: 20 minutes
Cooking Time: 1 hour 30 minutes
Chilling Time: 12 hours
Total Time: 13 hours 50 minutes

This keto lemon curd cheesecake is a lemon lover's dream dessert. It's a low-carb lemon cheesecake that features a rich and tangy lemon curd topping that is low in carbs and keto friendly.


Keto Crust

Keto Cheesecake

Keto Lemon Curd

  • 1 cup of granulated sugar substitute
  • 1 cup of fresh lemon juice, about 3 large lemons
  • ¼ cup and 1 tablespoon of unsalted butter ( the additional tablespoon of butter will be added once the lemon curd is done)
  • 8 large egg yolks (room temperature)
  • 1 tablespoon of freshly grated lemon zest
  • 1/2 teaspoon of lemon extract
  • ¼ tsp of sea salt


Keto Crust

  1. Preheat oven to 350 degrees.
  2. In a large mixing bowl, using a wooden spoon, combine the melted butter, and sugar substitute and mix until fully incorporated.
  3. Next, add the almond flour and sea salt.
  4. Press the crust in a lightly greased 9-inch springform pan.
  5. Bake in a 350-degree oven for 15 to 20 minutes or until the crust is lightly browned.
  6. Allow the crust to cool in the pan before adding the cheesecake batter.

Keto Lemon Curd

  1. Create a double boiler on the stovetop by placing a large glass mixing bowl over simmering water. Do not allow the bowl to touch the water, or use a regular double boiler.
  2. Once the water begins to simmer lightly, add the 1/4 cup of butter to the mixing bowl and allow the butter to melt.
  3. To the slightly cooled butter, add eight egg yolks one at a time, making sure to whisk quickly.
  4. Next, add the sugar substitute, lemon juice, lemon extract, lemon zest, and sea salt.
  5. Combine all the ingredients and whisk until the lemon curd thickens. This will take anywhere from 5-7 minutes.
  6. Add the reserved tablespoon of butter to the warm curd and stir until thoroughly combined.
  7. After the curd is ready, you'll want to place it through a fine-meshed colander to remove the zest of the lemon and ensure it's velvety smooth.
  8. Once the lemon curd is made, place the bowl in the refrigerator with plastic wrap on the surface of the curd so that a crust does not form on top.
  9. You can store your keto lemon curd for up to a month in a sealed container in your refrigerator.

Keto Cheesecake Filling

  1. Preheat the oven to 325 degrees.
  2. In a large stand-up mixer or a large mixing bowl using an electric handheld mixer, beat softened cream cheese, lemon extract, sea salt, and sugar substitute until light, fluffy, and well incorporated.
  3. Next, add the five eggs one at a time.
  4. Alternatively, you can use a large-capacity blender to mix your cheesecake batter. In this case, you add all your cheesecake ingredients into the blender at once. But make every effort not to over blend as this can cause the cheesecake to collapse when baking.
  5. Pour the cheesecake batter into the cooled almond crust.
  6. Securely wrap the cheesecake pan with a large sheet of heavy-duty aluminum or two pieces of regular foil. Cover the bottom and most of the sides tightly with the foil. This is in preparation for the bain-marie.
  7. Place your springform pan in a large roasting pan that is large enough to accommodate the pan without touching the sides.
  8. Next, carefully pour boiling water into the roasting pan until the water reaches halfway up the sides of the springform pan.
  9. Bake your cheesecake for 70-90 minutes or until the cheesecake is just set and doesn't jiggle when moved.
  10. Do not be concerned if your cheesecake has cracks on the surface after baking. This is perfectly normal.
  11. Carefully remove the cheesecake from the roasting pan (bain-marie), run a butter knife along the sides of the cheesecake, and then release the lever of the springform pan.
  12. Allow your cheesecake to cool on the kitchen counter fully, then wrap it with cling wrap and refrigerate for at least 12 hours or overnight.
  13. Once the cheesecake has had time to chill thoroughly, add the lemon curd topping to only the top of the cheesecake.
  14. To slice your cheesecake, dip a sharp knife in hot water and wipe the blade clean each time. Serve your cheesecake after it's been allowed to come to room temperature (about 15 minutes).
  15. Store your cheesecake in the refrigerator for up to 5 days or freeze it for up to 3 weeks.
