This creamy keto flan tastes so indulgent, you’d never guess it’s low-carb! The rich sugar-free custard base topped with a gooey caramel sauce is a truly decadent treat.
Flan is one of my favorite desserts. The rich custard base with a sweet caramel syrup on top is such an indulgence.
So when I’m really in the mood for something decadent, I love making this low-carb flan! The taste and texture are very similar to traditional caramel custard. Many people can’t even tell the difference.
But unlike traditional egg pudding, each slice only has 0.5 net carbs! Which means that you can dive into this rich dessert totally guilt free.
The trick to making flan keto friendly is swapping out the sugar for a low carb sweetener and using heavy cream instead of condensed and evaporated milk. The rest of the ingredients for an egg custard are totally low-carb!
How to Make Keto Flan
To make the recipe, you’ll prep the sauce and custard on the stove, combine and bake in the oven, then allow to cool. It’s a very simple process that just involves some heating and mixing!
Prepare the Caramel Syrup
- In a small saucepan, heat a ½ cup of the granular sweetener with blackstrap molasses (optional) on medium-low until the sweetener has melted.
- Once melted, stir to combine and then quickly pour the mixture into the bottom of a 2-quart round baking dish or 9.5 inch deep dish pie pan.
- Let it stand for at least 10 minutes.
Prep the Custard
- In a medium saucepan, heat the cream and water to a boil, then remove from heat.
- In a medium bowl, whisk together the eggs, salt, and the remaining ⅓ cup of granular sweetener.
- To temper the eggs, add 1 cup of the warm cream mixture into the egg mixture while stirring continuously. Then, return everything to the saucepan and mix well.
- Stir in the vanilla, then pour everything over the caramelized sweetener in the prepared baking pan.
Bake the Keto Flan and Cool
- Place the baking dish in a larger baking pan. Fill the larger pan with boiling water to a depth of about 1 inch to create a water bath.
- Place both baking dishes in the oven and bake at 325°F for 55-60 minutes until the center is set. The mixture should still wiggle a bit.
- Remove the smaller baking dish with the flan from the water bath and set it on a wire rack.
- Allow the flan to cool for about an hour, then place it in the refrigerator to chill completely.
- Once fully chilled, remove from the refrigerator and run a knife along the edge of the baking dish to release the sides of the flan. Then, invert onto a rimmed serving plate to extract the flan.
Your delicious sugar-free flan is ready to enjoy! Any leftovers should be stored in the refrigerator.
Best Sweetener for Low-Carb Flan
There are many keto sweeteners to choose from when baking. The most popular ones contain erythritol, a keto-friendly sugar alcohol with zero impacting carbs.
When making the caramel syrup, I don't recommend using any sweetener with erythritol. That's because it tends to crystallize after melting and cooling. You'll get much better results using the kabocha extract sweetener BochaSweet.
You can also use an allulose sweetener blend for the syrup. But I've had the best results with kabocha extract. A erythritol sweetener blend is fine to use for the custard because it gets mixed in with other ingredients.
Baking Pans for Flan
When making keto flan, there's no need for a special mold pan. I usually just use a Pyrex pie plate or 2-quart baking dish. However, you need to be careful when running a knife along the sides as bit of custard may flake off.
You can also use 6 to 8 ramekins instead of a large pan to divide the custard into individual serving sizes. Baking time will be reduced to about 30 to 40 minutes for ramekins.
