Ingredients
I tested this keto flan four times before I nailed the ratio. Creamy, sweet, zero eggy taste, and only 2.4 g net carbs per serving.
For the Caramel Base
- 1/2 cup sugar free caramel syrup
For the Flan Custard
- 3 large eggs
- 1 egg yolk
- 1 cup macadamia nut milk or nut milk of choice
- 1/2 cup heavy whipping cream
- 1/2 cup powdered erythritol
- 1 teaspoon lemon zest
- 1/4 teaspoon vanilla
How to Make Keto Flan
Step 1: Preheat the Oven
Preheat your oven to 325 degrees Fahrenheit. This ensures that your keto flan cooks evenly.
Step 2: Prepare the Caramel Base
- Pour sugar free caramel syrup into a loaf pan, ramekin, or small cake pan.
- Tilt the pan slightly to coat the bottom evenly with the caramel syrup. Set aside.
Step 3: Blend Eggs and Yolks
Add the large eggs and egg yolk to your blender. Blend until smooth for an even consistency in your custard mixture.
Step 4: Combine Ingredients
- Add nut milk, heavy cream, powdered erythritol, lemon zest, and vanilla extract to the blender.
- Blend again until all ingredients are well mixed and smooth.
Step 5: Pour Custard Mixture
Pour the custard mixture into your prepared loaf pan or cake pan over the caramel base.
Step 6: Create a Water Bath
Place the filled pan into a large baking dish. Fill it with hot water until it reaches halfway up the sides of your flan pan (be careful not to get any water into your custard).
Step 7: Bake
Bake at 325 degrees Fahrenheit for about 60 to 75 minutes. The top should be set but still lightly jiggly when done. Remove from the oven and water bath.
Step 8: Cool and Unmold
Let it cool on a rack for about 30 minutes. Then transfer it to the refrigerator for at least 8 hours to fully set. To unmold, run a knife around the edges of the loaf pan. Place your serving dish on top of the pan and carefully flip them together. If needed, let it sit at room temperature for a few minutes or place it back in warm water briefly before flipping again if it doesn’t come out easily. Enjoy!
How to Serve Keto Flan

How to Perfect Keto Flan
Creating the perfect keto flan takes some finesse. Here are some tips to ensure your flan turns out creamy and delicious every time.
- Use Fresh Ingredients: Fresh eggs and high-quality nut milk yield a smoother custard.
- Blend Thoroughly: Ensure all ingredients are blended until completely smooth for an even texture.
- Monitor Baking Time: Keep an eye on the custard; it should be set but still jiggle slightly in the center when done.
- Cool Gradually: Allowing the flan to cool slowly prevents cracks from forming on its surface.
- Refrigerate Overnight: For best results, let your flan chill in the fridge for at least 8 hours before serving to enhance flavor.
Best Side Dishes for Keto Flan
Pairing your keto flan with the right side dishes can elevate your dessert experience. Consider these options for a well-rounded meal.

Common Mistakes to Avoid
Making Keto Flan can be a delightful experience, but it’s easy to make mistakes. Here are some common pitfalls to watch out for:
-
Overmixing the Custard: Blending too long can introduce air into the mixture, resulting in a less smooth texture. Blend just until combined for the best results.
-
Wrong Baking Temperature: Baking at too high a temperature can cause the flan to crack. Always maintain a steady 325 degrees Fahrenheit for even cooking.
-
Skipping the Water Bath: Not using a water bath can lead to uneven cooking and texture issues. Ensure the pan is halfway submerged in hot water for optimal results.
-
Ignoring Cooling Time: Cutting into the flan too soon can ruin its structure. Allow it to cool completely and set in the refrigerator for at least 8 hours before serving.
-
Not Using Fresh Ingredients: Old eggs or dairy can affect flavor and consistency. Always use fresh ingredients for the best tasting Keto Flan.
-
Improper Unmolding Technique: If you don’t loosen the sides properly, your flan might break when flipping it onto a plate. Use a knife carefully around the edges before inverting.
