How to Make Low Carb Baked Egg Custard

1. Preheat the oven

Set your oven to 325°F (165°C). Place your baking dishes in a deep tray for a water bath.

2. Whisk the eggs

In a bowl, whisk eggs until smooth and fully combined.

3. Add cream and sweetener

Pour in heavy cream and sweetener. Mix until smooth and slightly pale.

4. Pour into baking dishes

Divide evenly into ramekins or foil trays, leaving a little space at the top.

5. Add nutmeg (optional)

Lightly sprinkle nutmeg over the top for a warm, classic flavor.

6. Bake in a water bath

Add hot water to the baking tray (halfway up the sides of the dishes). Bake for 30–40 minutes.

7. Check for doneness

The edges should be set, while the center has a slight jiggle.

8. Cool and serve

Let cool for 10–15 minutes or refrigerate for a firmer texture.

Tips for the Best Custard

✔ Always use a water bath
This prevents curdling and keeps the texture silky.

✔ Don’t overwhisk
Too much air can create bubbles instead of smooth custard.

✔ Watch the jiggle test
Slight wobble in the center means it’s perfectly baked.

✔ Chill for best texture
Overnight refrigeration makes it even creamier.

✔ Strain for extra smoothness
Optional, but gives a restaurant-style finish.
