​The Ultimate 3-Ingredient Low-Carb Baked Egg Custard

 

​Creamy, Dreamy, and Guilt-Free in Just 40 Minutes
​This elegant dessert proves that you don’t need sugar or complex ingredients to achieve a decadent, melt-in-your-mouth finish. By using heavy cream and a high-quality sugar alternative, this custard remains keto-friendly while maintaining the nostalgic flavor of a traditional French Crème Renversée.

​Ingredients

​3 Large Eggs: Fresh, room-temperature eggs provide the best structure and "lift."
​2 Cups Heavy Cream: For a rich, velvety mouthfeel. (For a lighter version, you may use half-and-half).

​1/3 Cup Granulated Sweetener: Use a 1:1 sugar replacement like Erythritol, Allulose, or Monk Fruit.

​Pro Tip: While this is a 3-ingredient base, a pinch of sea salt or a teaspoon of pure vanilla extract will significantly elevate the flavor profile without adding carbs.
​Instructions

​1. Preparation and Preheating

​Preheat your oven to 325°F (160°C). Place 4 to 6 ceramic ramekins into a deep baking dish. Boil a kettle of water; this will be used for the bain-marie (water bath) to ensure the eggs cook gently without curdling.

​2. Temper the Custard Base
​In a medium mixing bowl, whisk the eggs and your chosen sweetener until well-combined and slightly frothy. In a small saucepan, heat the heavy cream over medium heat just until it begins to simmer (do not let it reach a rolling boil).
​Slowly pour the warm cream into the egg mixture in a thin stream, whisking constantly. This "tempering" process prevents the eggs from scrambling.

​3. The Water Bath Method
​Divide the mixture evenly among the ramekins. Carefully pour the boiling water into the outer baking dish until it reaches halfway up the sides of the ramekins. This surrounding steam ensures a perfectly smooth, crack-free surface.

​4. Bake to Perfection
​Bake for 30–35 minutes. The custards are done when the edges are set but the centers still have a slight, uniform jiggle when nudged.

​5. Cooling and Serving
​Remove the ramekins from the water bath immediately and let them cool to room temperature. For the best texture, refrigerate for at least 2 hours before serving.
