Step-by-Step Instructions
Step 1: Prepare the Fruit Filling
Start by preparing your strawberry and rhubarb filling. Combine the sliced strawberries, chopped rhubarb, and 1/4 cup of sugar in a medium-sized saucepan over medium heat. Stir occasionally, allowing the mixture to simmer for about 10 minutes until the fruit begins to soften and release its juices.
Step 2: Make the Custard
While the fruit is cooking, it’s time to prepare the custard. In a separate bowl, whisk together the eggs, milk, heavy cream, remaining sugar, and vanilla extract until smooth. Be sure to whisk continuously to prevent any lumps from forming.
Step 3: Combine the Fruit and Custard Mixture
Once the fruit has softened, remove it from the heat and add the cornstarch, stirring to thicken the mixture. Pour the custard mixture over the fruit, ensuring that everything is well combined. Add the melted butter to enhance the richness of the dessert.
Step 4: Bake the Dessert
Pour the combined fruit and custard into a greased baking dish. Bake in a preheated oven at 350°F (175°C) for about 30 minutes, or until the custard is set and the top has a golden-brown hue. The consistency should be firm, but still creamy.
Step 5: Cool and Serve
Let the dessert cool for at least 15 minutes before serving. This dessert is best served warm, with a dollop of whipped cream or a scoop of vanilla ice cream to complement the flavors.

Healthier Alternatives for the Recipe

- With a Light Fruit Salad: Balance the richness of the custard with a refreshing fruit salad made from seasonal fruits like blueberries, kiwi, and melon.
- Warm with Tea or Coffee: This dessert pairs beautifully with a hot cup of tea or coffee, making it perfect for an afternoon treat.

Common Mistakes to Avoid
Here are a few common mistakes to avoid to ensure that your Strawberry Rhubarb Custard Dessert turns out perfectly:
- Overcooking the Fruit: Be careful not to overcook the strawberries and rhubarb. You want them to soften, but still hold their shape for a pleasant texture.
- Not Whisking the Custard Properly: If the custard isn’t whisked thoroughly, it can form lumps. Be sure to whisk continuously until the mixture is smooth.
- Using Too Much Sugar: The sweetness of the strawberries and rhubarb should shine through, so don’t overwhelm the dish with sugar. Taste the fruit before adding the full amount of sugar and adjust accordingly.
Storing Tips for the Recipe
This dessert is best served fresh, but if you have leftovers, here’s how to store them:
- Refrigerating: Store any leftover custard in an airtight container in the refrigerator for up to 3 days. The custard may firm up slightly, so be sure to reheat it gently in the microwave or oven.
- Freezing: If you want to freeze the dessert, place individual portions in freezer-safe containers. To reheat, thaw in the fridge overnight, then warm in the oven at 300°F (150°C) for about 10 minutes.
