    Preparation and Cooking Overview

    Making homemade sugar-free custard is easier than you would think. First, combine warm cream with whisked eggs, then pour it into ramekins, and finally bake using a water bath. The result will be perfectly set edges with a luscious, slightly jiggly center.

    Chef's note

    This keto recipe offers a low-carb version of the basic traditional custard. If you want some extra flavors, add a pinch of ground cinnamon or nutmeg to the custard mixture before baking. They add warm spice perfect for holiday parties.

    How to Make Keto Custard: Step-by-Step Guide

    Cooking Methods

    • Baking in a water bath

    Preparation Steps

    1. Gather and measure all the ingredients.
    2. Place your ramekins or custard cups in a deep baking dish.
    3. Separate 4 egg yolks in a small bowl.

    Cooking Instruction

    1. In a medium saucepan, heat the heavy cream over medium heat until it just starts to simmer. Remove from heat and set aside.
    2. Then in a mixing bowl, whisk the egg yolks, keto sweetener, vanilla extract, and salt until fully combined.
    3. Slowly pour the warm cream into the egg mixture, whisking constantly to avoid cooking the eggs.
    4. Once combined, strain the mixture through a fine mesh sieve to remove any egg solids (optional for an ultra-smooth custard).
    5. Pour the custard mixture into the prepared ramekins.
    6. Fill the baking dish with hot water until it reaches halfway up the sides of the ramekins.
    7. Bake for 30-35 minutes or until the custards are set around the edges but still slightly jiggly in the center.
    8. Remove from the oven and let the custards cool in the water bath for 10 minutes, then transfer to a wire rack to cool completely.

    Chef's pro tip

    To make sure your custard comes out smooth, it’s important to whisk the eggs thoroughly and slowly add the hot cream to temper them.

    What to Serve with Keto Custard?

    You can enjoy this keto custard on its own, or top it with a few fresh berries for added flavor and texture. Alternatively, dust it with cinnamon or a light sprinkling of powdered erythritol for a finishing touch.

    How to Make It Healthier

    To cut down on calories or fat, replace half of the heavy cream with unsweetened almond milk. This will still give you a rich texture but with fewer calories.

    Storage Instructions

    Once baked, the custards can be stored for days, making them perfect for meal prep or entertaining. The best storage practice is:

    • To refrigerate: Store leftover custard in the fridge in an airtight container or cover the ramekins with plastic wrap. The custards will stay fresh for up to 3 days.

    Recipe Wrap-Up and Conclusion

    This Keto Custard recipe is a must-try for anyone who loves creamy, indulgent desserts but wants to keep their carbs low. It’s rich, smooth, and has just the right amount of sweetness, making it the perfect treat for any time of the day. Give it a try and enjoy a guilt-free, keto-friendly dessert that’s sure to impress!

    Frequently asked questions

    Yes, you can substitute heavy cream with full-fat coconut milk for a dairy-free keto custard.

    The water bath helps the custard cook evenly and prevents it from curdling.

    Yes, but using only egg yolks gives the custard a creamier texture. If you use whole eggs, the custard may turn out slightly firmer.

    Grainy custard is usually caused by overcooking or failing to temper the eggs properly. To avoid this, whisk constantly while adding the warm cream.

    Yes, you can use other keto-friendly sweeteners like monk fruit or stevia. Feel free to adjust the quantity to taste.

    No, it's not recommended to make the custard mixture ahead of time due to the raw eggs. For best results, prepare and bake the custard on the same day.
