I often forget how much I like lemon desserts. Being the chocoholic that I am, I will reach past the sweet lemon treats for the gooey dark stuff. Keto chocolate cake or rich keto chocolate mousse almost always wins out.

But one bite of something like this keto instant pot cheesecake and it all comes rushing back to me. That bright lemony flavor just dances on your tongue.

And once you try making keto cheesecake in a pressure cooker, you may never make it any other way again! But just in case, I’ve included oven-baking instructions too.

Keto Instant Pot Cheesecake

There is some sort of magic that occurs when cooking cheesecake in a pressure cooker. It’s not really any easier than oven-baked cheesecake, but the consistency is simply amazing. It’s so creamy and dense, and less prone to cracking or sinking.

I have a few other flavors as well, including keto pecan pie cheesecake and cookies and cream cheesecake. Every time I bake cheesecake in an Instant Pot, it turns out perfectly.

This keto lemon cheesecake came out so beautifully, I found I didn’t want to dress it up with anything but a little whipped cream and some long strands of lemon zest

Ingredients

Keto instant pot cheesecake requires the same basic ingredients as regular cheesecake. You will need:

Almond flour (see Frequently Asked Questions for alternatives)
Powdered sweetener
Butter
Lemons (juice and zest)
Cream cheese
Lemon extract
Eggs
Heavy whipping cream
Salt

How to make keto lemon instant pot cheesecake

Putting together the crust and the filling is similar to an oven-baked cheesecake. However, you do have to take some extra precautions to make sure no water leaks into the cake during cooking. Here are my best tips for getting it right:

Prepping the cake

Use the right size pan: Cooking cakes in an Instant Pot requires a 7-inch pan to fit inside properly. They aren’t too expensive and that smaller size is useful for other recipes too.
Prep the crust: This is an almond flour crust but you can use any nut or seed meal instead. Press firmly and evenly into the bottom.
Use powdered sweetener: I use Swerve Confectioners the crust, the filling, and the topping, as it helps eliminate any grittiness. You can add up to 1 cup in the filling, depending on how sweet you like it.
Lemon zest, lemon juice, AND lemon extract: Too much lemon juice will result in thin filling that won’t set. The addition of the zest and the extract provide the best flavor.
Add some egg yolks: You could just use two whole eggs, but the yolks give the cheesecake a natural yellow color.
Don’t over-beat: As with any cheesecake, it’s important to mix in the eggs and cream until just combined. Over-beating whips too much air into a cheesecake filling, causing it to rise more rapidly, and then fall and crack.

Cooking the cheesecake

Wrap the pan in foil: This step is absolutely critical so don’t even think about skipping it. You need to wrap the bottom of the pan tightly so water doesn’t get forced into the seam between the bottom and the sides of the pan.
Top with some paper towel and more foil: The paper towel layer helps absorb any moisture that sneaks in there, but you don’t want it to touch the top of the cake. Then you wrap more foil around the top to provide another layer of protection.
Prepare the pot: Add a cup of water to the bottom of the Instant Pot and set the trivet in there. Carefully lower the foil-wrapped pan onto the trivet (or use a trivet with handles).
Cook on manual high: Every Instant Pot is a bit different so cooking on manual allows us all to use the same function.
Allow the pressure to release naturally: Don’t vent the lid when cooking is complete, simply allow the pressure to release naturally. The cake will continue to cook in this state.
Chill the cake: Once the Keto Instant Pot Cheesecake is done, remove the foil and paper towel, allow to cool completely, and the refrigerate 3 hours until set.

Frequently Asked Questions

I don’t have a pressure cooker. Can I make this in the oven?

I have included oven-baking instructions in the Notes section of the recipe. If you use a larger pan (8 or 9 inches), you will need to double the crust and the cheesecake will bake through faster.

Can I use a different sweetener?

You can but if you use allulose in the filling, you may find that it takes much longer to set properly in the fridge.

Do I really need to wrap it in all that foil?

Yes, you absolutely do. Pressure cookers create a high pressure environment that can force moisture into the pan. If you don’t wrap it thoroughly, moisture will get into the seams at the bottom or in through the top and make it very soggy.

Can I make this as plain cheesecake, without the lemon?

You bet! Just add a bit more cream to the fill-in (2 to 3 tablespoons) and some vanilla extract.

Storage Information

Store the cheesecake in the fridge, tightly wrapped, for up to a week. You can also freeze it for up to a month. I recommend leaving the whipped cream topping off until the cake is thawed.

Equipment

Ingredients

Crust

½ cup almond flour
1 teaspoon freshly grated lemon zest
2 tablespoon powdered Swerve Sweetener
⅛ teaspoon salt
1 ½ tablespoon butter melted

Cheesecake Filling

1 lb cream cheese well softened
⅔ cup powdered Swerve Sweetener (more if you like it sweeter)
1 teaspoon freshly grated lemon zest
¼ cup fresh lemon juice
1 teaspoon lemon extract
1 large egg room temperature
2 large egg yolks room temperature
2 tablespoon heavy whipping cream

Garnish

⅓ cup heavy whipping cream
1 tablespoon powdered Swerve Sweetener
Lemon zest or lemon slices

Instructions

Crust

Line the bottom of the springform pan with a circle of parchment paper cut to fit. Grease the paper and the sides of the pan.
In a medium bowl, whisk together the almond flour, lemon zest, sweetener, and salt. Stir in the melted butter until the mixture begins to clump together.
Press firmly and evenly into the bottom of the prepared pan and set aside.

Cheesecake Filling

In a large bowl, beat the cream cheese until smooth, then beat in the sweetener. Then beat in the lemon zest, lemon juice, and lemon extract until well combined.
Add the egg and egg yolks, and beat in until just combined, then beat in the whipping cream until just combined. Do not overbeat.
Pour the filling over the crust and gently shake the pan back and forth to even out the top.

To cook

Wrap the bottom of the springform pan tightly in a large piece of foil. Place a piece of paper towel over the top of the springform pan (not touching the cheesecake) and then wrap foil around the top as well. Your whole pan should be mostly covered in foil to keep out excess moisture.
Add 1 cup of water to the bottom of the pressure cooker. Set the cheesecake on the trivet and carefully lower into the pot. (You can also simply use the trivet that came with your IP and lower the cheesecake in by hand).
Close the lid and set the Instant Pot to manual mode for 35 minutes on high. Once the cooking time is complete, let the pressure to release naturally (do not vent it).
Lift out the cheesecake and let it cool to room temperature, and then refrigerate for 3 or 4 hours, or even overnight.

Garnish

In a medium bowl, whip the cream with the sweetener until it holds stiff peaks. Pipe decoratively or spread on the top of the cheesecake.
Decorate with lemon zest or lemon slices.

Notes

Oven instructions:

No need to wrap the pan in foil.
You may also want to bake the bottom crust for 10 minutes at 325F to help it firm up.
Bake the cheesecake at 300F for at least 30 minutes. Check on it every 5 minutes after that. Because I did not try this in the oven, I can’t tell you exactly how long it will take to bake.
The edges should be set but the center should still jiggle slightly when the pan is shaken.
