How to Make Fail-Proof Keto Egg Custard
This recipe is designed to be simple and straightforward. Even if you’ve never made custard before, you’ll find this process easy to follow. Let’s break it down step-by-step so you understand every detail.
Step 1: Preheat the Oven
Preheat your oven to 325°F (163°C). This low temperature ensures that your custard will bake gently, avoiding curdling or overcooking.
Step 2: Prepare the Custard Mixture
In a medium-sized mixing bowl, crack the 4 large eggs and whisk them until they are well combined. You can use a hand whisk, but if you want a smoother texture, feel free to use a hand mixer on a low setting.
Next, gradually add the ⅓ cup powdered erythritol (or monk fruit sweetener) to the eggs. Whisk the mixture until the sweetener dissolves completely, ensuring there are no lumps.
Now, slowly pour in the 1 cup heavy cream and the 1 cup unsweetened almond milk. Continue whisking until the mixture is smooth and homogeneous. Add the 1 teaspoon vanilla extract and ¼ teaspoon sea salt to enhance the flavor. The vanilla will give your custard a rich, aromatic scent, while the salt balances the sweetness.
Step 3: Strain the Mixture (Optional but Recommended)
For an extra-smooth custard, you can strain the mixture through a fine-mesh sieve before pouring it into the ramekins. This step helps remove any egg bits that didn’t fully incorporate, giving you a silky texture.
Step 4: Prepare the Water Bath
Place your ramekins in a large baking dish or roasting pan. A water bath (or “bain-marie”) is essential for custards because it ensures gentle, even cooking. Boil water in a kettle or pot, and once it’s hot, carefully pour the water into the baking dish around the ramekins. The water should reach halfway up the sides of the ramekins.
This technique prevents the custard from overcooking by insulating it from direct oven heat. It also helps the custard maintain a smooth and creamy texture.
Step 5: Pour and Bake
Carefully pour the custard mixture into each ramekin, filling them about ¾ of the way full. If you want a little extra flavor, sprinkle a pinch of nutmeg or cinnamon over the top of each one.
Place the baking dish in the oven and bake the custards for about 30-40 minutes. You’ll know they’re done when the edges are set, but the centers still have a slight jiggle. The custard will continue to set as it cools.
Step 6: Cool and Serve
Once the custards are done baking, carefully remove the ramekins from the water bath. Let them cool on a wire rack until they reach room temperature. Afterward, you can refrigerate them for a few hours if you prefer a chilled custard.
For serving, enjoy them as-is, or top with a dollop of whipped cream or a sprinkle of cinnamon for extra flavor. These custards can be served for dessert, but they also make a delightful snack or even a breakfast treat if you’re craving something rich and creamy.

Notes and Tips:
- Use Fresh Eggs: Fresh eggs are essential for a smooth, creamy custard. Older eggs can result in a more grainy texture.
- Avoid Overbaking: Custards are delicate and can curdle if overcooked. Keep an eye on them toward the end of the baking time. The center of the custard should have a slight jiggle when you remove it from the oven.
- Straining for Smoothness: If you want an incredibly silky-smooth custard, don’t skip the step of straining the custard mixture. This helps remove any bits of unincorporated egg.
- Sweetener Options: You can experiment with different keto-friendly sweeteners like stevia, allulose, or a blend of erythritol and stevia. Just be sure to use a powdered form to avoid graininess.
- Flavor Variations: While vanilla is classic, you can mix things up by adding a little lemon zest, almond extract, or even some unsweetened cocoa powder for a chocolate version of this custard.
- Serving Suggestions: This custard pairs beautifully with fresh berries, a dollop of whipped coconut cream, or even a drizzle of sugar-free caramel sauce.
