- Servings: 8
Ingredients
For the Tart Crust:
- 1 ¼ cups all-purpose flour
- ½ cup unsalted butter, chilled and cubed
- ¼ cup granulated sugar
- 1 large egg yolk
- 2 to 4 tablespoons ice water
- A pinch of salt
For the Filling:
- 2 cups rhubarb, chopped
- 1 cup granulated sugar
- 3 large eggs
- 1 cup heavy cream
- 1 teaspoon vanilla extract
- 2 tablespoons all-purpose flour
- A pinch of salt
- Optional: powdered sugar for dusting

Step-by-Step Instructions
Prepare the Tart Crust:
- In a large mixing bowl, combine the all-purpose flour, sugar, and salt.
- Add the cubed butter to the flour mixture. Using a pastry cutter or your fingers, mix until the mixture resembles coarse crumbs.
- Stir in the egg yolk. Gradually add ice water, one tablespoon at a time, until the dough come together. Be careful not to overmix.
- Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes.
Pre-bake the Crust:
- Preheat your oven to 375°F (190°C).
- Roll out the chilled dough on a lightly floured surface until it is about ¼ inch thick. Carefully transfer it to a 9-inch tart pan, pressing it into the bottom and up the sides.
- Trim the edges and place a piece of parchment paper over the crust. Fill with pie weights or dried beans to prevent bubbling.
- Bake in the preheated oven for 15 minutes. Remove weights and parchment paper, then bake for an additional 10 minutes until lightly golden. Set aside to cool.
Prepare the Rhubarb Filling:
- In a large bowl, combine chopped rhubarb and ½ cup sugar. Let it sit for about 10 minutes to release moisture, then drain any excess liquid.
- In a separate bowl, whisk together the eggs, remaining sugar, heavy cream, vanilla extract, flour, and salt until smooth.
Assemble and Bake the Tart:
- Spread the rhubarb evenly over the cooled crust. Pour the custard mixture over the rhubarb, ensuring it’s evenly distributed.
- Bake in the oven for 25–30 minutes, or until the custard is set and a knife inserted in the center comes out clean.
Cool and Serve:
- Allow the tart to cool completely on a wire rack before slicing.
- Dust with powdered sugar before serving, if desired.
Pro Tips for Perfect Results
- Chill Your Ingredients: Keep your butter and water cold for a flakier pie crust.
- Do Not Overmix the Dough: Overmixing can develop gluten, resulting in a tough crust.
- Monitor Baking Time: Ovens vary; keep an eye on your tart to prevent overbaking.
- Fresh Rhubarb is Key: Use fresh, firm rhubarb for the best flavor and texture.
- Let It Cool Completely: Cooling naches the tart allows for easier slicing and enhances flavor as it settles.
Variations and Substitutions
- Healthier Swaps: Substitute half of the heavy cream with Greek yogurt for a lighter custard that still provides creaminess.
- Add Citrus: Lemon or orange zest in the custard can brighten the flavor profile even more.
- Nut Crust: Swap half of the flour for ground almonds or hazelnuts for a nuttier tart crust.
Storage and Reheating Tips
- Storage: Store any leftovers in the refrigerator in an airtight container for up to three days.
- Reheating: To reheat, place slices in a 350°F (175°C) oven for about 10 minutes, or you can microwave them for 30 seconds or so, being careful not to overheat.
