One of my favorite things ever is showing you how to make desserts low carb. This low carb keto custard recipe was one of the easiest ones to make, because it’s not that different from regular custard. This dish has no flour to begin with, so we just swap in a low carb sweetener. And since keto egg custard is baked in individual ramekins, it has built-in portion control!

Even though the total time for this low carb custard recipe is around 40 minutes, most of it is hands-off time in the oven. The actual active prep process is super quick!

Plus, you only need 5 ingredients. I wouldn’t be surprised if you have everything you need to make this keto vanilla custard at home right now.

How To Make Egg Custard

Keto egg custard looks really elegant, so you’d never guess how easy it is to make. But it is.

While you preheat the oven, beat the eggs to make them frothy, like this:

Next, heat cream, powdered Besti, and sea salt in a small saucepan over medium-low heat. Stir occasionally, until the temperature reaches 180 degrees F. Be careful not to overheat!

After removing from heat, add in the vanilla extract.

Next, start whisking the eggs and slowly pour the cream mixture into the eggs in a thin stream. It’s important to pour slowly and keep whisking constantly as you do this! This is called tempering.

Set out 6 ramekins and divide the mixture among them. Sprinkle with a little bit of nutmeg if you’d like.

Use a baking pan with tall sides and place the ramekins inside. Then, add enough water to reach halfway up to the top of the ramekin dish. The water will reduce sudden temperature changes, so the custard cooks evenly and doesn’t crack or overcook.

Bake for approximately 30-40 minutes, until just barely (but not fully!) set.

Allow the custard to cool and rest until it reaches room temperature before serving.

My Recipe Tips

• It’s best to use a thermometer to test that the custard has reached 180 degrees F, but if you don’t have one, watch for bubbles. Small bubbles will begin forming around the edges when it’s done. Don’t let it boil!
• If you have any lumps in the custard, you can strain it before baking. Use a mesh strainer and place it over a bowl, then pour the contents. Then you can toss any lumps out.
• Keto vanilla custard can taste egg-y if you overheat it. If it comes to a boil, then the eggs will cook and end up tasting like… well, scrambled eggs. No, thanks! Always use a whisk when mixing the ingredients in this keto custard recipe to make sure nothing sticks to the pan. And most importantly, pour very slowly and whisk quickly when tempering, to avoid cooking the eggs.
• Keep an eye on the keto egg custard – it should be jiggly when done. It’s ready when it’s barely starting to set, and a knife inserted in the center comes out clean.

Frequently Asked Questions

• What Does Custard Taste Like? If you’ve never tasted homemade custard before, you’re in for a treat! It has a velvety texture that is deliciously sweet.Baked keto custard tastes very similar to the inside of creme brulee, just without the crunchy top. Also, creme brulee is often made with just the yolks, while this custard includes the whole eggs. Don’t worry if you’re low carb, though – this keto vanilla custard uses a natural sugar-free sweetener, so it tastes sweet without any sugar. And, my family and friends can’t tell the difference when I make this low carb custard recipe.
• Is Custard The Same Thing As Pudding? No, low carb egg custard and pudding are not the same things. Custard is creamy, is made with eggs and baked in a water bath. Pudding doesn’t necessarily require eggs and milk is the main ingredient. Regular versions are often thickened with cornstarch, but I have a low carb pudding recipe coming soon for you!
• Do I Serve Custard Warm Or Cold? You can serve this low carb custard recipe either warm or cold depending on your preference, but I much prefer it cold. Top it with some strawberries and whipped cream if you’d like!
