How to Make Rhubarb Custard Tart

Pro Tips

To ensure your tart turns out perfectly, don’t pre-cook the rhubarb too much before it goes into the tart; we want it to soften beautifully in the oven while still holding its shape and a slight textural bite. When preparing your crust for this Rhubarb Custard Tart, be sure to chill it thoroughly before blind baking; this helps prevent shrinkage and ensures a crisp, sturdy base for your filling. After baking, resist the urge to slice it right away; letting it cool completely is crucial for the custard to fully set, giving you those clean, creamy slices.

My Secret Trick: A tiny pinch of freshly grated nutmeg alongside a whisper of lemon zest in the custard mixture really elevates the flavor, adding a warm, bright complexity without overpowering the rhubarb.

How to Store Rhubarb Custard Tart

• Once completely cooled, store your tart loosely covered with plastic wrap or in an airtight container in the refrigerator for up to 3-4 days.
• While technically possible, freezing is not recommended as the custard’s texture can become grainy upon thawing.
• This tart is best enjoyed chilled or at room temperature; reheating can alter the delicate texture of the custard.

Nutritional Benefits

While we certainly indulge in this for the pure joy of it, our Rhubarb Custard Tart does bring a few little bonuses to the table. Rhubarb itself is a good source of dietary fiber and vitamin K, and the eggs in the custard provide a dose of protein. It’s all about balance and enjoying delicious, seasonal treats!

FAQs

Can I use frozen rhubarb for this recipe?

Yes, you absolutely can use frozen rhubarb! Just be sure to thaw it completely and drain any excess liquid before adding it to your tart shell. This prevents a watery custard and helps maintain the integrity of your Rhubarb Custard Tart.

How do I prevent a soggy bottom crust?

The key to a crisp bottom crust is blind baking. Make sure to thoroughly chill your pie crust, line it with parchment paper and pie weights, and bake it until lightly golden before adding the filling. This creates a barrier against the moisture from the custard and fruit.

What’s the best way to tell when the custard is set?

Your custard is perfectly set when the edges are firm and slightly puffed, but the center still has a slight, gentle wobble when you gently shake the tart. It will continue to firm up as it cools, resulting in that wonderfully silky texture.

Can I add other fruits to this tart?

Absolutely! While the classic is divine on its own, strawberry is a natural pairing with rhubarb. You could also experiment with raspberries or blackberries for a delightful twist, just be mindful of their moisture content.

Ingredients

  

For the Tart Crust

• 1.5 cups All-purpose flour
• 8 tablespoons Unsalted butter very cold, diced (1/2 cup)
• 0.25 teaspoon Salt
• 4-6 tablespoons Ice water

For the Rhubarb Filling

• 3 cups Fresh rhubarb trimmed and cut into 1/2-inch pieces
• 0.75 cup Granulated sugar divided
• 1 tablespoon Cornstarch
• 1 teaspoon Lemon zest

For the Custard Topping

• 2 Large eggs
• 1 Large egg yolk
• 1 cup Heavy cream
• 1 teaspoon Vanilla extract
• 0.125 teaspoon Salt

Equipment

• 9-inch tart pan with removable bottom
• Rolling Pin
• Large mixing bowls
• Whisk
• Parchment Paper
• Pie Weights or Dried Beans

Method

 

Prepare the Tart Crust

• In a large bowl, whisk together the flour and 0.25 teaspoon salt. Cut in the very cold, diced butter using a pastry blender or your fingertips until the mixture resembles coarse meal with some pea-sized pieces of butter remaining. Gradually add the ice water, 1 tablespoon at a time, mixing until the dough just comes together. Be careful not to overmix! Form the dough into a disc, wrap tightly in plastic wrap, and refrigerate for at least 30 minutes, or up to 2 days.
• Preheat your oven to 375°F (190°C). On a lightly floured surface, roll out the chilled dough into a 12-inch circle. Carefully transfer it to a 9-inch tart pan with a removable bottom, pressing it gently into the bottom and up the sides. Trim any excess dough. Prick the bottom of the crust all over with a fork. Line the crust with parchment paper and fill with pie weights (or dried beans). Bake for 15 minutes. Remove the parchment and weights, then bake for another 5-7 minutes, or until the crust is lightly golden. Let it cool slightly on a wire rack.

Prepare the Rhubarb Filling

• While the crust cools, prepare the rhubarb filling. In a medium bowl, combine the chopped rhubarb, 0.5 cup of the granulated sugar, cornstarch, and lemon zest. Toss gently to ensure the rhubarb is evenly coated.

Prepare the Custard Topping

• In another medium bowl, whisk together the large eggs, egg yolk, the remaining 0.25 cup granulated sugar, heavy cream, vanilla extract, and 0.125 teaspoon salt until the mixture is smooth and well combined.

Assemble and Bake the Tart

• Arrange the rhubarb mixture evenly in the pre-baked tart shell. Carefully pour the custard mixture over the rhubarb, ensuring it's distributed evenly.
• Bake for 35-45 minutes, or until the custard is set (a slight jiggle in the very center is okay) and the crust is golden brown. If the crust edges start to brown too quickly, you can loosely tent the tart with aluminum foil.
• Let the tart cool completely on a wire rack for at least 2-3 hours before slicing and serving. This is crucial for the custard to fully set and for clean slices.

Notes

For a perfectly crisp crust, don't skip the blind baking step! It creates a barrier that prevents a soggy bottom from the juicy rhubarb and custard.
Make-ahead magic: You can prepare the tart dough and chill it for up to 2 days, or blind bake the crust a day in advance. Store the blind-baked crust at room temperature.
Serve this tart on its own, or with a dollop of freshly whipped cream or a scoop of vanilla bean ice cream for an extra special treat.

Conclusion

There’s something truly special about baking, especially when it results in a dessert as comforting and elegant as this one. This tart isn’t just a recipe; it’s a moment of pure, unadulterated spring joy on a plate. I sincerely hope you find as much delight in making and sharing this beautiful Rhubarb Custard Tart as I do.
