Sugar-Free Low Carb Custard Recipe
Introduction
This sugar-free custard is a comforting, creamy dessert perfect for those watching their sugar and carb intake. Made with simple ingredients, it offers a smooth texture and rich vanilla flavor without the added sugar. It’s a classic treat reinvented for a low-carb lifestyle.

Ingredients
- 2 large egg yolks
- 3 large eggs
- ½ cup Swerve, granular
- Pinch of salt
- 3 cups hot milk, 2% (about 120°F/49°C, not boiling)
- 2 teaspoons vanilla extract
- Ground nutmeg
- Cooking spray of choice
Instructions
- Step 1: Preheat the oven to 325°F (163°C) and spray six 7-ounce ramekins (⅞ cup) with cooking spray.
- Step 2: In a mixing bowl, beat the eggs and egg yolks just to blend. Stir in the Swerve and a pinch of salt.
- Step 3: Slowly whisk in the hot milk (about 120°F/49°C), stirring constantly. Avoid using milk that is too hot to prevent the eggs from cooking prematurely and becoming lumpy. Add the vanilla extract and whisk again.
- Step 4: Prepare a shallow roasting pan by filling it about 1 inch (2.54 cm) deep with hot water to create a water bath.
- Step 5: Divide the custard mixture evenly into the prepared ramekins. Sprinkle a little ground nutmeg on top of each.
- Step 6: Place the ramekins in the water bath and set the pan on an oven rack about one-third from the top.
- Step 7: Bake until the custard sets, checking with a knife inserted into the center—it should come out clean. This usually takes about 90 minutes, but begin checking after 45 minutes in case they set earlier.
- Step 8: Carefully remove the ramekins from the water bath using tongs and let them rest for 10 minutes before serving. Dust with additional nutmeg if desired.
Tips & Variations
- If your custard mixture becomes lumpy due to overheated milk, try straining it before baking to smooth the texture.
- Use almond milk or another low-carb milk alternative if you prefer a dairy-free option, but note that texture may vary slightly.
- For added flavor, consider stirring in a pinch of cinnamon or a splash of almond extract along with the vanilla.
- Use a kitchen thermometer to ensure the milk is at the correct temperature to avoid curdling.
Storage
Store leftover custard covered in the refrigerator for up to 3 days. Reheat gently in a warm water bath or serve chilled, depending on preference. Avoid microwave reheating as it may cause the custard to separate.

FAQs
Can I use a different sweetener instead of Swerve?
Yes, you can substitute with other granular, low-carb sweeteners like erythritol or monk fruit sweetener in equal amounts. Be cautious with liquid sweeteners as they may alter the custard’s consistency.
Why is my custard lumpy?
Lumpiness usually happens when the milk is too hot and begins to cook the eggs prematurely. To prevent this, ensure the milk is warm but not boiling (about 120°F/49°C) before combining with the eggs.

Ingredients
Custard Base
- 2 large egg yolks
- 3 large eggs
- ½ cup Swerve, granular
- Pinch of salt
- 3 cups hot milk, 2% (120°F / 49°C, not boiling)
- 2 teaspoons vanilla extract
- Ground nutmeg, for sprinkling
- Cooking spray of choice, for greasing ramekins
Instructions
- Preheat and Prepare Ramekins: Preheat your oven to 325°F (163°C). Spray six 7-ounce ramekins with cooking spray to prevent sticking.
- Mix Eggs and Sweetener: In a mixing bowl, beat the egg yolks and whole eggs just until blended together. Stir in the granular Swerve and a pinch of salt until fully combined.
- Add Hot Milk and Vanilla: Slowly whisk the hot milk (around 120°F or 49°C) into the egg mixture while stirring constantly to prevent the eggs from cooking prematurely. Add the vanilla extract and whisk again. If the milk is too hot and causes lumps, strain the mixture to fix it.
- Prepare Water Bath: Place a shallow roasting pan on the counter and fill it about 1 inch (2.54 cm) deep with hot water to create a water bath, which will gently cook the custard.
- Fill Ramekins and Add Nutmeg: Pour the custard mixture evenly into the prepared ramekins. Sprinkle a light dusting of ground nutmeg on top of each.
- Bake the Custard: Place the ramekins in the roasting pan with water and position in the oven on a rack about one-third from the top. Bake until the custards set, which usually takes about 90 minutes. Check at 45 minutes to see if done early by inserting a knife—if it comes out clean, custards are ready.
- Cool and Serve: Using tongs, carefully lift the ramekins from the water bath once baked. Let them rest for 10 minutes at room temperature. Optionally, dust with additional nutmeg before serving for extra flavor.
Notes
- Ensure the milk temperature is around 120°F (49°C) to avoid curdling the eggs when mixing.
- If lumps form due to temperature shock, straining the custard mixture can help salvage it.
- Use a water bath to maintain gentle, even heat for the perfect custard texture.
- Check custards early as baking time may vary depending on your oven.
- This recipe is diabetic-friendly due to the use of Swerve, a sugar substitute, and low in carbs.
