Low FODMAP Custard (Simple, Creamy & Easy to Digest)
Custard is a simple dessert that doesn’t need much to be good. At its core, it’s just milk, eggs, and sugar cooked gently until smooth and thick. For people following a Low FODMAP diet, traditional custard can be tricky since it’s often made with regular milk or cream. This version uses lactose-free milk, which keeps the flavor and texture familiar while making it easier to digest.
This Low FODMAP custard is meant to be straightforward and reliable. It works well as a light dessert on its own, a make-ahead option to keep in the fridge, or a base for fruit and simple toppings. If you’re looking for a dessert that feels classic without being heavy, this one fits easily into most routines.
Why This Custard Is Low FODMAP
- Lactose-free milk is real dairy with the lactose removed, making it suitable for a Low FODMAP diet while still working like regular milk in custard.
- Egg yolks are naturally Low FODMAP and provide a thick, creamy texture without needing cream.
- Granulated sugar is Low FODMAP and sweetens the custard without contributing fermentable carbs.
- Vanilla extract, used in a small amount, adds flavor without triggering digestive symptoms.
Variations
- For a slightly richer custard, replace up to ¼ cup of the milk with lactose-free half-and-half if tolerated.
- Stir in a pinch of cinnamon or nutmeg after cooking for a touch of added warmth.
- For a fruit-forward option, serve the custard with Low FODMAP berries like strawberries, blueberries, or raspberries.
- Layer chilled custard with fruit in small jars for an easy make-ahead option.
Tips for Best Results
- Cooking the custard over low, steady heat helps it thicken gently and prevents curdling or graininess.
- To avoid scrambled eggs, it’s important to temper the egg yolks slowly by whisking in the warm milk a little at a time.
- Once the mixture is back on the stove, stirring constantly helps the custard thicken evenly and prevents sticking to the pan.
- If you notice small bits after cooking, straining the custard through a fine mesh sieve will smooth out the texture.
- Should the custard set too firmly after chilling, adjusting the thickness with a splash of warm lactose-free milk brings it back to a spoonable consistency.
Serving Ideas
This is an easy dessert to serve on its own, but it also pairs well with other simple treats.
- Serve it with fresh berries or spoon roasted strawberries over it for a warm-and-cool contrast.
- For a bit of crunch, try crumbling a gluten-free orange ginger snap or cranberry almond granola over the top before serving.
- Enjoy it after a savory dinner, alongside other desserts such as coconut chia pudding or coconut ginger chia crème brûlée.
