Ingredients

Here’s what you’ll need to make this irresistible tart:

Tart Shell: The foundation of this dessert. Made with butter, flour, and sugar, it’s perfectly crisp, rich, and buttery. It’s the perfect complement to the velvety ganache and tangy rhubarb.

Dark Chocolate: The star of the ganache. Rich and smooth, dark chocolate adds a luxurious, slightly bitter taste that pairs beautifully with the sweetness of the rhubarb.

Heavy Cream: A key ingredient for the ganache. It helps create that rich, smooth texture that makes every bite melt in your mouth.

Rhubarb: Roasted to perfection, rhubarb adds a tart, fruity layer that cuts through the richness of the chocolate. It’s the surprising yet perfect addition to this decadent dessert.

Instructions

Let’s make this dream dessert together!

Preheat the Oven: Start by preheating your oven to 375°F (190°C). This will get the oven nice and hot so that the tart shell bakes perfectly crisp.

Prepare the Rhubarb: Trim and cut your rhubarb into small pieces. Lay them on a baking sheet, sprinkle with a little sugar, and roast them in the oven for about 15-20 minutes until they’re tender and caramelized. This brings out their natural sweetness and balances their tartness.

Make the Tart Shell: In a food processor, combine the flour, sugar, and butter. Pulse until the mixture resembles coarse crumbs. Press the mixture into a tart pan, making sure to cover the bottom and sides evenly. Bake the shell for about 15 minutes until golden brown.

Make the Ganache: While the tart shell and rhubarb are cooling, it’s time for the ganache. In a saucepan, heat the heavy cream until it just begins to simmer. Pour the hot cream over the chopped dark chocolate and let it sit for a minute before stirring until smooth and glossy. It should be thick and creamy.

Assemble the Tart: Once the tart shell has cooled slightly, pour the ganache into the shell. Spread it out evenly, and then gently spoon the roasted rhubarb on top. The contrast of the rich chocolate with the tangy rhubarb is absolutely heavenly.

Chill and Serve: Let the tart chill in the fridge for at least an hour to set the ganache. After it’s chilled, slice it up and serve!

How to Serve Roasted Rhubarb Chocolate Tart

This tart is stunning on its own, but here are a few ideas for serving it up:

Fresh Cream: A dollop of whipped cream or a scoop of vanilla ice cream on the side complements the rich flavors and adds a touch of creaminess.

Fresh Berries: A handful of fresh berries like raspberries or strawberries can enhance the tart’s natural fruity notes and add a pop of color.

Mint Garnish: For an extra touch of elegance, garnish with fresh mint leaves. They add a refreshing contrast to the sweetness of the tart.

Additional Tips

Here are a few more tips to make your Roasted Rhubarb Chocolate Tart even more spectacular:

Make Ahead: You can prepare the tart shell and roasted rhubarb a day ahead. Just assemble the tart the day you plan to serve it.

Switch Up the Chocolate: If you prefer milk or white chocolate over dark, feel free to swap it out! The ganache will be a little sweeter, but it will still be delicious.

Use Frozen Rhubarb: If fresh rhubarb isn’t in season, frozen works just as well. Just be sure to thaw it and drain any excess moisture before roasting.

Storage Tips: Store leftovers in the fridge for up to 3 days. The tart shell may soften a little, but the flavors will still be amazing.

FAQ Section

Q1: Can I use a store-bought tart shell?
A1: Absolutely! If you’re short on time, a store-bought tart shell will work just fine.

Q2: Can I substitute the rhubarb with another fruit?
A2: Yes! If rhubarb isn’t your favorite, try using roasted strawberries, raspberries, or even pears. They’ll pair beautifully with the chocolate ganache.

Q3: Can I make this ahead of time?
A3: Yes, you can prepare the tart a day or two ahead. Just chill it in the fridge until you’re ready to serve.

    • Add cold butter and rub it into the dry mixture using your palms until it resembles fine breadcrumbs.
    • Make a well in the center of the mixture and add the egg yolks. Use a fork or your fingers to work the yolks into the dough.

    • Freeze the tart shell for 30 minutes until very cold.
