Ingredients You’ll Need
The magic of this tart lies in its simplicity and the harmony between each component. The ingredients are straightforward yet thoughtfully chosen to create a balanced flavor and beautiful texture that elevates every bite.
- 1 1/4 cups all-purpose flour: This forms the sturdy but tender base of the crust, giving the tart its essential structure.
- 1/4 cup powdered sugar: Adds a subtle sweetness to the crust without overpowering the rhubarb or chocolate flavors.
- 1/4 teaspoon salt: Enhances all the other flavors, making their tastes pop.
- 1/2 cup cold unsalted butter (cubed): Creates a flaky, rich crust that melts in your mouth.
- 1–2 tablespoons cold water: Helps bind the dough together perfectly without making it tough.
- 4 oz dark chocolate (chopped): The star of the filling, offering a deep, intense flavor that complements the tartness of rhubarb.
- 1/2 cup heavy cream: Makes the chocolate ganache smooth, creamy, and indulgent.
- 1 teaspoon vanilla extract: Adds a warm, fragrant note that rounds out the chocolate’s richness.
- 2 cups rhubarb (cut into 1-inch pieces): Provides that signature tangy punch while roasting softens it just enough to be tender but still textured.
- 2 tablespoons granulated sugar: Balances the natural tartness of the rhubarb with just the right amount of sweetness.
- 1 tablespoon orange juice: Infuses a subtle citrus brightness that lifts the roasted rhubarb’s flavor beautifully.
How to Make Roasted Rhubarb Chocolate Tart Recipe
Step 1: Prepare the Tart Crust
Start by preheating your oven to 375°F (190°C). In a food processor, pulse together the flour, powdered sugar, and salt until well combined. Then add the cold, cubed butter and pulse until the mixture resembles coarse crumbs, almost like sand. This step ensures a buttery, flaky crust. Slowly add cold water, one tablespoon at a time, pulsing gently just until the dough holds together. Press this dough evenly into a 9-inch tart pan and prick the bottom with a fork to prevent bubbling. Chill for 15 minutes — this resting time helps the crust hold its shape during baking. Finally, blind bake the crust for about 18 to 20 minutes or until it’s a lovely light golden color, then set it aside to cool completely.
Step 2: Roast the Rhubarb
While the crust is baking, toss the rhubarb pieces in granulated sugar and that splash of vibrant orange juice. The sugar sweetens, and the orange juice adds a bright twist. Spread the rhubarb mixture evenly on a baking sheet and roast it in the oven for 15 to 20 minutes. You want the rhubarb to become tender but still hold its shape, which adds a wonderful texture contrast in the final tart.
Step 3: Prepare the Chocolate Ganache Filling
For the luscious filling, gently heat the heavy cream in a saucepan until it just begins to simmer. Pour this hot cream over the chopped dark chocolate in a heatproof bowl and let it sit undisturbed for 2 minutes; this softens the chocolate. Then stir until you achieve a perfectly smooth, glossy ganache. Pour in the vanilla extract and mix well to add that subtle aromatic depth.
Step 4: Assemble the Tart
Pour the chocolate ganache into the cooled tart shell and smooth the surface with a spatula. Gently arrange the roasted rhubarb pieces on top, making sure each slice shows off the gorgeous contrast of pink-red rhubarb against rich, velvety chocolate. Once assembled, chill the tart in the refrigerator for at least 2 hours to let it set completely so each slice holds its shape beautifully.
How to Serve Roasted Rhubarb Chocolate Tart Recipe
Garnishes
A simple dollop of whipped cream or a few fresh mint leaves can elevate this tart to even greater heights. The creaminess balances the tartness, and the mint adds a refreshing herbal note that brightens every forkful. You might also consider a light dusting of powdered sugar for an elegant finish.
Side Dishes
This tart pairs wonderfully with a scoop of vanilla ice cream or a crisp, lightly sweetened Greek yogurt to complement and cool the rich chocolate and tangy rhubarb. Fresh berries on the side also enhance the fruity flavors without overwhelming the palate.
Creative Ways to Present
For a stunning dessert display, serve individual slices on contrasting plates to highlight the colors of the tart. You can drizzle a little extra chocolate sauce or a bright raspberry coulis on the side to add a gourmet touch. Even layering the tart atop a decorative doily can give it a charming, rustic feel that’s perfect for gatherings.
Make Ahead and Storage
Storing Leftovers
Keep any uneaten tart slices in an airtight container in the refrigerator. Stored this way, the tart will stay fresh and delicious for up to 3 days. The flavors actually deepen after resting, making leftovers even more tempting.
Freezing
If you want to save this Roasted Rhubarb Chocolate Tart Recipe for later, slice it first, then freeze individual pieces wrapped tightly in plastic wrap and foil. This method helps keep the textures intact. Freeze for up to a month for best results.
Reheating
Because of the ganache filling, it’s best to enjoy this tart chilled or at room temperature. If needed, let frozen slices thaw in the refrigerator overnight and then bring them to room temperature before serving. Avoid microwave reheating to keep the crust perfect and avoid melting the ganache too much.
FAQs
Can I use frozen rhubarb for this Roasted Rhubarb Chocolate Tart Recipe?
Yes, frozen rhubarb can work if you thaw and drain it well to remove excess moisture. Keep in mind that fresh rhubarb will provide the best texture and vibrant flavor.

For the Chocolate Ganache Filling
- 4 oz dark chocolate, chopped (60–70% cocoa)
- 1/2 cup heavy cream
- 1 teaspoon vanilla extract
Instructions
- Prepare the tart crust: Preheat your oven to 375°F (190°C). In a food processor, pulse together the flour, powdered sugar, and salt until combined. Add the cold, cubed butter and pulse until the mixture resembles coarse crumbs. Slowly add cold water one tablespoon at a time, pulsing after each addition until the dough starts to come together. Press the dough evenly into a 9-inch tart pan, prick the bottom with a fork to avoid bubbling, and chill the crust in the refrigerator for 15 minutes.
- Bake the crust: Place the chilled tart pan in the preheated oven and bake for 18 to 20 minutes, or until the crust is lightly golden brown. Remove from oven and set aside to cool completely.
- Roast the rhubarb: While the crust bakes, toss the rhubarb pieces with granulated sugar and orange juice to coat evenly. Spread them out on a baking sheet and roast in the oven for 15 to 20 minutes, or until the rhubarb is tender but retains its shape.
- Make the chocolate ganache filling: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Remove from heat and pour the hot cream over the chopped dark chocolate placed in a heatproof bowl. Let it sit for 2 minutes to melt the chocolate, then stir gently until the mixture is smooth and glossy. Stir in the vanilla extract.
- Assemble the tart: Pour the chocolate ganache into the cooled tart shell and smooth the surface with a spatula. Gently arrange the roasted rhubarb pieces evenly on top of the ganache.
- Chill before serving: Refrigerate the assembled tart for at least 2 hours to allow the ganache to set properly. Serve chilled or at room temperature. Optionally, garnish with whipped cream or fresh mint leaves for an elegant touch.
