Skip the crust and keep all the creamy goodness. This keto crustless cheesecake gives you the classic cheesecake experience without the carbs or hassle. It’s smooth, rich, and lightly sweet—not cloying—so each bite feels balanced.
You don’t need fancy tools or tricky techniques, just a few key ingredients and a little patience. If you’re craving an effortless dessert that fits your low-carb goals, this one’s a winner.
Ingredients
Method
- Prep the pan and oven: Preheat your oven to 325°F (163°C). Grease a 9-inch springform pan well, including the sides. For extra insurance, line the bottom with parchment and grease it too.
- Warm the ingredients: Make sure cream cheese, eggs, and sour cream are at room temperature. This helps create a smooth, lump-free batter.
- Beat the cream cheese and sweetener: In a large bowl, use a hand mixer on medium speed to beat the cream cheese and powdered sweetener until smooth and fluffy, about 2 minutes. Scrape down the bowl as needed.
- Add sour cream, vanilla, lemon, and salt: Mix in the sour cream, vanilla, lemon juice, and salt until just combined. Don’t overbeat.
- Incorporate the eggs: Add eggs one at a time on low speed. Mix until each egg is just blended before adding the next. Stop as soon as the batter looks smooth.
- Tap out air bubbles: Give the bowl a few firm taps on the counter to release excess air. This helps prevent cracks.
- Set up a water bath (optional but recommended): Wrap the outside of the springform pan with heavy-duty foil. Place it in a large roasting pan and pour hot water around it, coming halfway up the sides. This keeps the cheesecake moist and bakes it gently.
- Bake: Pour the batter into the prepared pan. Bake for 50–65 minutes, until the edges are set and the center still jiggles slightly like Jell-O. Avoid overbaking.
- Cool gradually: Turn off the oven. Crack the door open and let the cheesecake sit inside for 45 minutes. This slow cool helps prevent cracks.
- Chill completely: Remove from the water bath, discard the foil, and run a thin knife around the edge to loosen. Cool to room temperature, then cover and chill at least 6 hours, preferably overnight.
- Serve: Release the springform ring. Slice with a hot, clean knife, wiping between cuts. Add your favorite keto-friendly toppings.

Keeping It Fresh
Cheesecake loves the fridge. Store it covered in an airtight container for up to 5 days.
If you made toppings, keep them separate and spoon on right before serving to keep the texture clean.
For longer storage, freeze individual slices. Wrap each slice tightly in plastic, then place in a freezer bag. They’ll keep for about 2 months.
Thaw overnight in the fridge for the best texture, or at room temperature for 30–45 minutes if you’re in a hurry.
Health Benefits
- Low in carbs: Skipping the crust removes a major source of carbs, keeping each slice keto-friendly.
- Satisfying fats: Full-fat dairy helps you feel full longer, which can support appetite control on a ketogenic diet.
- Protein boost: Cream cheese and eggs add protein, which supports muscle maintenance and satiety.
- Customizable sweetness: Using erythritol, allulose, or monk fruit helps you control sugar intake while still enjoying dessert.
Note: Nutrition will vary based on your sweetener and serving size, but most slices land in the low-carb range when made as written.
Common Mistakes to Avoid
- Using cold ingredients: Cold cream cheese creates a lumpy batter and can lead to a dense texture. Let everything warm to room temp first.
- Overmixing the eggs: Beating on high speed whips in air, which can cause cracks. Mix on low and stop as soon as it’s smooth.
- Skipping the water bath: You can skip it, but you risk a drier texture and more cracks.
A water bath gives the creamiest results.
- Overbaking: If the center is fully firm in the oven, it’s overdone. Pull it when the middle still has a gentle jiggle.
- Rushing the chill: Cheesecake needs hours to set. Cutting in early leads to messy slices and a soft texture.
Alternatives
- Sweeteners: Allulose gives the silkiest texture and no cooling aftertaste.
Erythritol works but can crystallize slightly after chilling. A blend with monk fruit often tastes the most sugar-like.
- Dairy swaps: Replace sour cream with full-fat Greek yogurt for a tangier bite. For a lactose-lighter option, use lactose-free cream cheese and sour cream.
- Flavor twists: Add 1–2 teaspoons lemon zest, a scraped vanilla bean, or 1 teaspoon almond extract.
For chocolate, whisk in 2–3 tablespoons unsweetened cocoa and increase sweetener slightly to balance the bitterness.
- Mini cheesecakes: Divide batter among a lined muffin tin and bake 18–22 minutes. Great for portion control and faster chilling.
- Berry swirl: Simmer berries with a keto sweetener until thick, cool, and dollop onto the batter. Swirl with a knife before baking.
FAQ
How do I know when my cheesecake is done?
Look for set edges and a center that still jiggles slightly when you nudge the pan.
If it looks like firm custard in the middle, it’s overbaked. Start checking around 50 minutes, as ovens vary.
Can I make this without a springform pan?
Yes. Use a well-greased 9-inch cake pan or deep pie dish lined with parchment on the bottom.
You won’t be able to release the sides, so slice and lift carefully. A springform is still the easiest option for clean edges.
Which sweetener tastes best?
Allulose delivers the smoothest texture and least aftertaste. Erythritol is widely available and works well, though it can feel a bit cool on the tongue.
Monk fruit blends offer a nice middle ground. Adjust to your sweetness preference.
Do I have to use a water bath?
No, but it helps. If you skip it, place a pan of hot water on the rack below to add moisture, and watch the bake time closely.
The texture may be slightly firmer without a bath.
Why did my cheesecake crack?
Common reasons include overmixing, overbaking, or rapid temperature changes. To prevent cracks, mix gently, bake until just set, cool in a cracked oven door, and run a knife around the edge while it’s still warm to release tension.
How many carbs are in a slice?
It depends on your sweetener and slice size. A typical 1/12 slice often lands around 3–5g net carbs when made with allulose or erythritol and no toppings.
For exact numbers, plug your brands into a nutrition calculator.
Can I make it ahead?
Absolutely. Cheesecake improves after a night in the fridge. Make it up to two days in advance, then slice and add toppings right before serving.
Can I add a crust and keep it keto?
Yes.
Press a mix of almond flour, melted butter, sweetener, and a pinch of cinnamon into the pan, par-bake for 8–10 minutes, cool, and add the filling. Still low-carb, just not crustless.
Wrapping Up
This keto crustless cheesecake is proof that simple can be spectacular. With a handful of ingredients and a patient chill, you’ll get a creamy, elegant dessert that fits your low-carb lifestyle.
Keep the steps gentle, avoid overbaking, and let it rest overnight. Serve it plain or dressed up with berries, and enjoy a slice that tastes every bit as indulgent as the classic—without the carb-heavy crust.
