The Essence of Keto Baked Custard

Originating from a traditional French recipe, this Keto Baked Custard has been reimagined to cater to a low-carb diet without compromising on taste or texture. It’s a testament to the versatility of keto cooking, proving that even the most classic desserts can be enjoyed within the dietary framework.

At the heart of this dish are eggs and heavy cream, both keto staples. Eggs are a powerhouse of nutrition, offering high-quality protein and fats, while heavy cream brings in the richness and mouthfeel that’s essential to custard. The use of granulated erythritol as a sweetener keeps the sugar content at bay, ensuring that you can savor the sweetness without the carb overload.

The inclusion of a vanilla bean or extract adds an aromatic depth that elevates the custard from simple to sublime. The subtle warmth of freshly grated nutmeg complements the vanilla, adding a layer of spice that’s both comforting and intriguing.

Every ingredient in this recipe has been chosen for its ability to support a ketogenic lifestyle. The high fat content is perfect for maintaining ketosis, while the minimal carbs make it an ideal dessert or snack. It’s a dish that not only satisfies your sweet cravings but also nourishes your body with keto-friendly goodness.

Ingredients for Keto Baked Custard

Mastering the Method

Creating the perfect Keto Baked Custard is all about technique. The process begins with preheating your oven and preparing your ramekins in a deep baking dish. This ensures an even and gentle cooking environment, crucial for achieving that signature custard texture.

When whisking the eggs, erythritol, and salt, it’s important to combine them thoroughly to create a smooth base. The key to a lump-free custard lies in the tempering process. As you slowly pour the warm cream into the egg mixture, whisk continuously to prevent the eggs from scrambling.

Straining the mixture is a step you don’t want to skip. It might seem like an extra task, but it’s essential for removing any unwanted bits and ensuring a silky-smooth custard. The water bath is another crucial element. It moderates the oven’s heat, allowing the custard to cook evenly and gently.

Keep a watchful eye on your custards as they bake. They should be just set with a slight wobble in the center. Overbaking is the nemesis of custard, so start checking for doneness a few minutes before the timer goes off. Once out of the oven, patience is key. Let them cool and then chill to set completely, and you’ll be rewarded with a custard that’s the epitome of indulgence.

Variations to Savor

Almond Infused Keto Custard

For a twist on the classic, infuse your custard with the nutty essence of almond. Replace the vanilla extract with almond extract and add a sprinkle of slivered almonds on top before baking. The result is a dessert with a marzipan-like flavor that’s utterly irresistible.

Citrus Zest Keto Custard

Bring a zing to your custard by incorporating citrus zest. Lemon, lime, or orange zest can be whisked into the egg mixture, imparting a fresh and tangy note that cuts through the richness. It’s a sunny variation that’s sure to brighten your day.

Chocolate Swirl Keto Custard

For chocolate lovers, swirl in some melted sugar-free dark chocolate before baking. The chocolate will create beautiful patterns and add a decadent touch to your custard, making it a dessert that’s as visually appealing as it is delicious.

Smart Substitutions

While the original recipe is designed to be keto-friendly, there are always ways to tailor it to your preferences or pantry availability. If heavy cream is not on hand, full-fat coconut milk can be a great lactose-free alternative. It will bring a tropical twist to the custard, along with the added health benefits of medium-chain triglycerides (MCTs).

For those who prefer a different sweetener, monk fruit sweetener can replace erythritol in equal amounts. This natural sweetener is zero-glycemic and will not spike your blood sugar levels, making it an excellent choice for maintaining ketosis.

If you’re out of nutmeg, cinnamon can be a wonderful substitute. It offers a similar warm spice profile and can complement the vanilla flavor beautifully. Just a light dusting on top before baking will do the trick.

Frequently Asked Questions

Can I use a different type of sweetener? Yes, you can use other keto-friendly sweeteners like monk fruit or stevia. Just be mindful of the conversion rates as they can vary from brand to brand.

Is it possible to make this dairy-free? Absolutely! Swap out the heavy cream for full-fat coconut milk for a dairy-free version that’s just as creamy and satisfying.

How do I know when the custard is set? The custard should have a slight jiggle in the center when gently shaken. If it’s too liquid, give it a few more minutes in the oven, checking frequently.

Can I make this custard in advance? Yes, this custard is perfect for making ahead. Once cooled, cover and refrigerate. It can be made up to two days in advance.

How should I store leftovers? Store any leftover custard in the refrigerator, covered, for up to three days. Enjoy it chilled straight from the fridge!

  • Mixing bowl
  • Whisk
  • Saucepan
  • Fine mesh sieve
  • Measuring Cup or Pitcher
  • Ramekins
  • Deep Baking Dish


  • 4 large eggs
  • 2 cups heavy cream 16 fl oz / 473 ml
  • cup granulated erythritol 2.8 oz / 80 g
  • 1 vanilla bean, split and scraped, or 2 tsp vanilla extract
  • ¼ tsp nutmeg, freshly grated
  • A pinch of salt


  • Preheat your oven to 350°F (175°C). Prepare six ramekins by placing them in a deep baking dish.
  • In a mixing bowl, whisk together the eggs, erythritol, and salt until well combined.
  • In a saucepan, heat the heavy cream with the vanilla bean (pod and scraped seeds) or vanilla extract until it is just about to simmer. Remove the vanilla bean pod if used.
  • Slowly pour the warm cream into the egg mixture, whisking continuously to temper the eggs and prevent them from scrambling.
  • Strain the mixture through a fine-mesh sieve into a large measuring cup or pitcher to ensure a smooth custard and to remove any egg strands or vanilla pod remnants.
  • Ladle the custard mixture evenly into the ramekins. Sprinkle the tops with freshly grated nutmeg.
  • Pour hot water into the baking dish around the ramekins, being careful not to get any water into the custards. The water should come halfway up the sides of the ramekins to create a water bath.
  • Carefully place the baking dish in the oven and bake for 45 minutes, or until the custards are just set but still slightly wobbly in the center.
  • Remove the ramekins from the water bath and let them cool to room temperature. Then refrigerate for at least 2 hours to set completely before serving.
