This low carb 3-ingredient baked egg custard is exactly the kind of comforting treat my grandpa used to make when the pantry was almost bare. It’s warm, sweet, and simple enough to throw together after a long workday, using just eggs, cream, and a low-carb sweetener. Everything bakes up into a smooth, pale yellow custard with golden brown edges and a light dusting of nutmeg on top—nothing fancy, just the kind of dessert that quietly hits the spot every single time.
Serve this custard warm, straight from the oven after it’s had a few minutes to set, or chill it in the fridge for a firmer, pudding-like texture. It’s great on its own in small foil trays, but you can also pair it with a handful of fresh berries or a dollop of unsweetened whipped cream if you want to dress it up without adding many carbs.
A cup of coffee or decaf tea on the side makes it feel like a cozy, end-of-day ritual, especially on cold evenings.
Low Carb 3-Ingredient Baked Egg Custard
Servings: 4
Ingredients
4 large eggs
2 cups heavy whipping cream
1/3 cup granular low-carb sweetener (erythritol, monk fruit blend, or similar), plus a little extra to taste if needed
Ground nutmeg, for dusting on top (optional but recommended; not counted as one of the 3 main ingredients)
Directions
Preheat your oven to 325°F (165°C). Set two small foil trays (about 5x7 inches or similar) on a rimmed baking sheet to make it easier to move them in and out of the oven.
In a medium mixing bowl, whisk the eggs until the yolks and whites are fully blended and slightly frothy, but not foamy. This helps the custard bake up smooth.
Add the heavy whipping cream and the low-carb sweetener to the eggs. Whisk until the sweetener is mostly dissolved and the mixture looks uniform and pale yellow. Taste a small spoonful and add a bit more sweetener if you prefer a sweeter custard.
Carefully pour the custard mixture into the two foil trays, dividing it as evenly as you can. The trays should be no more than about 3/4 full so the custard has room to puff slightly.
If using, lightly dust the surface of each tray with ground nutmeg. A thin, even sprinkle is enough to give that classic warm flavor and the light brown speckled look on top.
Pour hot tap water into the rimmed baking sheet around the foil trays, creating a shallow water bath that comes about halfway up the sides of the trays. This helps the custard bake gently and prevents curdling.
Carefully slide the baking sheet into the preheated oven. Bake for 30–40 minutes, or until the custard is set around the edges with a slight jiggle in the center when you gently nudge the tray. The surface should be pale yellow with lightly golden brown edges.
Remove the baking sheet from the oven and carefully lift the foil trays out of the water bath. Let the custard cool on the counter for at least 10–15 minutes before serving warm, or let it cool completely and then chill in the fridge for 2–3 hours for a firmer texture.
Just before serving, you can add an extra light dusting of nutmeg on top if desired. Serve directly from the foil trays, scooping out portions with a spoon or cutting into squares once fully chilled.
Variations & Tips
To keep this true to the spirit of a pantry-bare, 3-ingredient recipe, the base is just eggs, heavy cream, and a low-carb sweetener, with nutmeg as a classic optional touch. If you want to tweak it, you can swap part of the heavy cream with unsweetened almond milk or another low-carb milk alternative for a lighter custard (just know it may not be quite as rich or firm). For a slightly different flavor, add a splash of vanilla extract or a pinch of cinnamon to the custard mixture before baking.
If you prefer individual portions, divide the custard into 4–6 small foil cups or ramekins and reduce the baking time, checking for doneness around 20–25 minutes. For an ultra-smooth texture, strain the custard mixture through a fine-mesh sieve into the foil trays before baking to catch any eggy bits.
Food safety tips: Always use fresh, clean eggs and avoid consuming the custard mixture raw. Make sure the custard reaches at least 160°F (71°C) in the center for safe consumption; it should look set around the edges with just a slight wobble in the middle. Cool leftovers promptly, cover, and store in the refrigerator, and enjoy within 3–4 days. Reheat gently in a low oven or enjoy chilled.
