Ingredients
- 4 large eggs
- 2 cups whole milk
- 1/3 cup granulated sugar
- 1 teaspoon pure vanilla extract
Instructions
Step 1: Prepare the Custard Dish
Lightly butter a heatproof 1-quart baking dish or soufflé dish that fits inside your slow cooker.
Make sure the dish has enough room around it for hot water to circulate.
Step 2: Warm the Milk
Pour the milk into a small saucepan and warm over low heat until it is steaming but not boiling.
Remove from the heat and allow it to cool slightly.
Warming the milk helps the sugar dissolve and makes it easier to combine with the eggs.
Step 3: Whisk the Eggs and Sugar
In a medium mixing bowl, whisk the eggs and granulated sugar until thoroughly combined.
Slowly pour the warm milk into the egg mixture while whisking continuously.
Add the vanilla extract and mix until smooth.
For an extra-silky custard, strain the mixture through a fine-mesh sieve before pouring it into the prepared dish.
Step 4: Fill the Dish
Pour the custard mixture into the buttered heatproof dish.
Cover the dish tightly with aluminum foil to prevent condensation from dripping onto the surface.
Step 5: Prepare the Slow Cooker
Place a folded kitchen towel or silicone trivet in the bottom of the slow cooker.
Set the custard dish on top.
Carefully pour hot water into the slow cooker until it reaches approximately halfway up the sides of the custard dish. Keep the water below the rim of the dish.
Step 6: Slow Cook Until Set
Cover the slow cooker with its lid.
Cook on LOW for approximately 2–3 hours, checking toward the end of the cooking time.
The custard is ready when the edges are set and the center still has a slight jiggle. An instant-read thermometer inserted into the center should register at least 160°F (71°C).
Cooking time varies depending on the slow cooker and the size of the custard dish.
Step 7: Cool and Chill
Carefully remove the custard dish from the hot water bath.
Remove the foil and allow the custard to cool briefly.
Refrigerate promptly and chill for at least 2–3 hours before serving.
Serve chilled for a classic, silky egg custard.
Tips for the Best Egg Custard
- Avoid boiling the milk: Hot milk is helpful, but boiling can make the mixture harder to combine smoothly.
- Temper the eggs: Add the warm milk gradually while whisking to prevent scrambled egg pieces.
- Strain the mixture: This removes small bits of egg and helps produce a smoother texture.
- Use LOW heat: Gentle cooking helps prevent a rubbery custard.
- Cover the dish: Foil keeps condensation from making the custard watery.
- Watch the center: A slight jiggle is normal; the custard will firm up further as it chills.
Easy Recipe Variations
These additions are optional and will increase the ingredient count.
- Cinnamon custard: Sprinkle ground cinnamon over the top before serving.
- Nutmeg flavor: Add a pinch of freshly grated nutmeg.
- Caramel topping: Drizzle caramel sauce over individual portions.
- Lemon custard: Add a little finely grated lemon zest.
- Maple flavor: Replace some of the sugar with maple syrup, adjusting the sweetness to taste.

Storage Instructions
Refrigerator: Store covered in the refrigerator for up to 3 days.
Freezer: Freezing is not recommended because the custard may become watery or grainy after thawing.
Serving: Keep refrigerated until ready to serve. Do not leave egg custard at room temperature for more than 2 hours.
Frequently Asked Questions
Why is my egg custard watery?
Watery custard can result from overheating, undercooking, or condensation dripping into the dish. Cover the dish tightly and cook gently until the custard is properly set.
Can I use low-fat milk?
Whole milk gives the richest and creamiest result. Lower-fat milk can be used, but the custard may be less rich.
Can I cook egg custard without a water bath?
The water bath is recommended because it helps distribute heat gently and evenly. This reduces the risk of overcooking the eggs.
How do I know when the custard is done?
The edges should be set while the center has a gentle jiggle. For food safety, the center should reach at least 160°F (71°C).
Can I make this custard ahead of time?
Absolutely. Prepare it the day before, cool it promptly, cover, and refrigerate. It is especially delicious served cold.
Can I make individual portions?
Yes. Divide the mixture among small heatproof ramekins that fit inside your slow cooker. Cooking time will be shorter, so begin checking for doneness earlier.
