The inspiration for this delightful Blueberry White Chocolate Ganache Tart sprang from my fiancé’s gentle request for a white chocolate creation. Frankly, I’m not usually the biggest enthusiast of white chocolate, often finding it overly sweet. However, I was utterly captivated by this tart from the very first bite. The texture is divine – sumptuously silky and smooth, especially when allowed to warm slightly to room temperature before serving. It delivers a perfect symphony of flavors: initially sweet, followed by a delightful, subtle tang from the blueberries, which then blossoms into a full, natural blueberry essence. And let’s not overlook that captivating color – entirely natural and undeniably stunning!

Whether you’re a seasoned baker or a curious beginner, the steps are straightforward, promising a rewarding experience with spectacular results. Get ready to impress your guests, or simply treat yourself, with this magnificent creation that proves white chocolate can indeed be the star of a truly balanced and flavorful dessert.
Essential Ingredients for Your Blueberry White Chocolate Ganache Tart
Crafting this incredible tart begins with selecting high-quality ingredients. Each component plays a vital role in achieving the perfect texture, flavor, and visual appeal. Here’s what you’ll need, along with a few pro tips:
- Unsalted butter: For the sweet tart crust, ensure your butter is at perfect room temperature. This allows it to cream smoothly with sugar, creating a tender, flaky crust.
- Granulated sugar: Used in both the crust and the ganache (indirectly, through the white chocolate) to provide sweetness and structure.
- All-purpose flour: The backbone of our delicate pâté sucrée, giving it just the right amount of structure without being tough.
- Eggs: One large egg, also at room temperature, is crucial for binding the tart dough and ensuring a consistent, smooth mixture.
- Blueberries: You can use either fresh or frozen blueberries. If using frozen, there’s no need to thaw them beforehand; they’ll cook down beautifully regardless. These provide the natural color and tangy fruit flavor that defines this tart.
- White chocolate: This is where quality truly shines. Opt for the best quality white chocolate you can find – it makes a significant difference in both taste and the ganache’s texture. I highly recommend Callebaut white chocolate chunks. While white chocolate chips can work in a pinch, they often contain stabilizers that prevent them from melting smoothly, leading to a less luxurious ganache. Investing in good couverture chocolate is key for a truly successful tart.
- Heavy whipping cream: The essential liquid for our ganache, providing richness and the perfect creamy consistency when combined with white chocolate.
- Kosher Salt: A tiny pinch enhances all the other flavors.
- Vanilla paste or extract: Adds a layer of warm, aromatic sweetness that complements both the blueberries and white chocolate. Vanilla paste offers a more intense flavor and visible specks.
- Egg whites (for Swiss Meringue – optional): For an elegant, toasted topping, egg whites are combined with sugar to create a stable, glossy meringue.
Mastering the Sweet Tart Crust (Pâté Sucrée)
The foundation of this tart is its crust – a sweet tart crust, also known as pâté sucrée. This dough is one of the most beloved and forgiving in the pastry world, making it ideal for both beginners and experienced bakers. Its tender, buttery texture and subtle sweetness perfectly complement the rich ganache filling.
The process for making pâté sucrée is remarkably similar to making sugar cookies. You start by creaming together softened butter and granulated sugar until light and fluffy. This step incorporates air, which contributes to the crust’s delicate texture. Next, a single room-temperature egg is added, binding the mixture, followed by a pinch of salt and the all-purpose flour. The ingredients are combined until a soft, pliable cookie-like dough forms.
A crucial step for a perfect sweet tart crust is chilling the dough. It will need to chill for at least 2 hours in the refrigerator. This rest period allows the gluten to relax, preventing shrinkage during baking, and makes the dough much easier to handle. So, plan your baking schedule accordingly!
Once adequately chilled, your dough is ready to be rolled out. Lightly flour your work surface and rolling pin, then roll the dough to an even thickness of about ⅛ to ¼ inch. Don’t worry if it cracks a little; pâté sucrée is incredibly forgiving, and any small imperfections can be easily patched later. Aim for a diameter approximately 2 inches wider than your chosen tart pan.
Carefully transfer the rolled dough into an 8-inch or 9-inch tart pan with a removable bottom. Gently press the dough into the bottom, corners, and up the sides of the pan to ensure an even shell. To remove excess dough, simply roll your rolling pin over the top edge of the pan. Any leftover dough scraps can be used to patch any thin spots or small tears, ensuring a strong and beautiful crust.

Crafting the Luminous Blueberry White Chocolate Ganache
The star of this tart is undoubtedly the ganache – a velvety, fruit-infused dream that marries the creamy richness of white chocolate with the vibrant essence of fresh blueberries. Here’s how to create this stunning filling:
Begin by preparing your blueberries. In a small saucepan over medium heat, gently cook down the fresh or frozen blueberries. As they warm, use the back of a wooden spoon to mash them, encouraging them to release their juices. Continue cooking until the mixture is liquidy and bubbling. This process concentrates their flavor and creates a beautiful, intense puree.
Next, pass the blueberry puree through a fine-mesh sieve into a bowl. Press firmly on the solids to extract as much liquid and flavor as possible, leaving behind only the skins and seeds. From this exquisite blueberry liquid, measure out exactly ¼ cup – this will be the essence of your ganache.
In a separate saucepan, heat the heavy whipping cream. Stir it occasionally to prevent scorching, and watch it closely until it just comes to a gentle simmer. Meanwhile, precisely chop your high-quality white chocolate and place it into a heatproof glass or metal mixing bowl. Uniformly chopped chocolate ensures even melting.
The moment the heavy whipping cream reaches a simmer, remove it from the heat and pour it directly over the chopped white chocolate. Immediately add the measured blueberry puree and a teaspoon of vanilla extract or paste to the bowl. Now, the critical step: allow the mixture to stand undisturbed for a full minute. This crucial “resting” period allows the hot cream to melt the chocolate thoroughly without over-agitating it, which helps prevent a split or grainy ganache.
After the minute has passed, begin stirring the mixture gently. Use a small spatula or spoon and start stirring from the center of the bowl, slowly expanding your stirs outwards. Continue until the mixture is completely homogenous, smooth, and glossy. You’ll notice the beautiful purple hue develop as the ingredients combine. Pour this exquisite blueberry white chocolate ganache into your pre-baked and cooled tart shell. Carefully transfer the tart, uncovered, to the refrigerator to set for a minimum of 2 hours. This chilling time is essential for the ganache to firm up to its perfect sliceable consistency.
Frequently Asked Questions About White Chocolate Ganache and Tarts
While you technically can, it is highly recommended to avoid white chocolate chips for ganache. White chocolate is notoriously trickier to work with compared to dark or milk chocolate due to its high milk solids and fat content, and absence of cocoa solids. High-quality white chocolate melts smoothly and evenly. Chocolate chips, on the other hand, often contain stabilizers (like soy lecithin) that are designed to help them hold their shape during baking, making them resistant to smooth melting. This becomes an even bigger issue with white chocolate chips. If you must use them, you will likely encounter unmelted pieces. Simply strain your ganache through a fine-mesh sieve into the cooled tart shell to remove any stubborn lumps.
A grainy or oily white chocolate ganache usually indicates that the heavy cream was either too hot, or you started stirring too soon after pouring the cream over the chocolate. White chocolate contains milk solids and cocoa butter but lacks cocoa solids, which normally help absorb the melting fat. Without sufficient time for the chocolate to melt gently (the “standing minute”), or if the cream is excessively hot, the cocoa butter can separate from the milk solids, resulting in an unappetizing split, oily, or grainy texture. Patience is key here.
Don’t despair if your ganache splits! It’s often salvageable. The most common fix is to gently warm the ganache over a double boiler (a bowl set over a pot of simmering water, ensuring the bowl does not touch the water). Stir continuously until it comes back together and becomes smooth. If it still resists, try adding a very small amount of warm milk (or even water) – about a teaspoon at a time – and continue stirring until the ganache emulsifies and achieves a smooth, unified consistency. Be careful not to add too much liquid.
Absolutely! This Blueberry White Chocolate Ganache Tart is an excellent make-ahead dessert. You can bake the tart shell a day or two in advance and store it at room temperature in an airtight container. The ganache filling can be made and poured into the cooled shell, then refrigerated for up to 3-5 days. For the best serving experience, allow the tart to come to room temperature for about 30 minutes before slicing, which enhances its silky smooth texture and flavor.
This tart is stunning on its own, but you can elevate it further. Garnish with fresh blueberries, a dusting of powdered sugar, or a sprig of fresh mint for a pop of color. If you prefer not to use Swiss meringue, a dollop of freshly whipped cream provides a lovely contrast. For an extra treat, serve it with a side of raspberry coulis or a scoop of vanilla bean ice cream.

Ingredients
Sweet Tart Dough
- 6 T unsalted butter room temperature (85g)
- ⅓ cup granulated sugar 67g
- ⅛ tsp kosher salt
- 1 large egg room temperature
- 1 ¼ cup + 2T all-purpose flour 165g
Ganache filling
- 1 cup fresh or frozen blueberries
- 12 oz white chocolate chopped, high quality recommended
- 1 cup heavy whipping cream 238 g
- 1 tsp vanilla paste or extract
Swiss Meringue (Optional Topping)
- 2 large egg whites
- ½ cup granulated sugar 100g
- Pinch salt
- 1 tsp vanilla paste or extract
Instructions
Sweet Tart Dough
- In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), cream together the room temperature butter, granulated sugar, and salt until the mixture is smooth and light. Incorporate the large egg, mixing until just combined, then scrape down the sides of the bowl to ensure everything is fully mixed. Finally, add the all-purpose flour and mix on low speed only until it’s just incorporated, forming a soft dough. Be careful not to overmix.
- Gently gather the dough, wrap it tightly in plastic wrap, and flatten it into a disc about 1 inch thick. Place this disc in the refrigerator to chill for approximately two hours. This chilling step is essential for easier rolling and a tender crust.
- Once chilled, remove the dough from the fridge and plastic wrap, allowing it to sit at room temperature for about 15 minutes to soften slightly. Lightly flour your work surface and rolling pin. Roll out the dough evenly to a thickness between ⅛ to ¼ inch. This dough is very forgiving, so if any cracks appear, they can be easily patched later. Roll the dough wide enough so it’s roughly 2 inches larger in diameter than your tart pan.
- Carefully transfer the rolled dough into your tart pan. Gently press it into the bottom, snugly against the corners, and up the sides of the pan. To remove any excess dough, simply roll your rolling pin over the top edge of the tart pan. Use any dough scraps to patch small holes or reinforce thin spots in the crust.
- Place the prepared tart shell into the freezer for 15 minutes. Meanwhile, preheat your oven to 325℉ (160℃). After chilling, remove the dough from the freezer and use a fork to dock (prick) the bottom of the tart shell multiple times. Line the shell with parchment paper and fill it completely with pie weights (or dried beans/rice) to prevent the crust from puffing up.
- Bake the weighted crust for 10 minutes. Carefully remove the pie weights and parchment paper, then continue baking for another 10-15 minutes, or until the crust is lightly golden brown and the bottom no longer appears moist or raw. Transfer the baked tart shell to a wire rack to cool completely before filling.
Blueberry White Chocolate Ganache
- In a small saucepan set over medium heat, cook down the fresh or frozen blueberries. Use the back of a wooden spoon to mash them as they cook, helping them release their juices. Continue cooking until the blueberries have broken down into a liquid and the mixture is bubbling gently.
- Carefully pour the cooked blueberry mixture through a fine-mesh strainer into a clean bowl. Press firmly on the solids with the back of a spoon to extract all the delicious blueberry liquid. Measure out exactly ¼ cup of this strained blueberry liquid and set it aside.
- Place your finely chopped white chocolate into a heatproof mixing bowl and set it aside. In a clean saucepan, heat the heavy cream over medium-high heat until it just begins to simmer, stirring occasionally to prevent it from scorching. Once simmering, immediately pour the hot cream over the chopped white chocolate, then add the measured blueberry liquid and vanilla extract. Allow this mixture to stand undisturbed for about one minute. After the minute, gently stir (do not whisk vigorously) the mixture from the center outwards until it comes together into a completely smooth, glossy, and vibrant ganache.
- Pour the luscious blueberry white chocolate ganache into your completely cooled tart shell. Carefully transfer the tart, uncovered, to the refrigerator and chill for at least two hours, or until the ganache is fully set.
- Before serving, remove the tart from the refrigerator and let it sit at room temperature for approximately 30 minutes. This allows the ganache to soften slightly, enhancing its silky texture and maximizing its flavor.
Swiss Meringue (Optional)
- Fill a saucepan with about 1 inch of water and bring it to high heat to create a double boiler. Place a heatproof bowl securely over the saucepan, ensuring the bottom of the bowl does not touch the simmering water.
- Add the egg whites, granulated sugar, and a pinch of salt to the bowl. Whisk gently but continuously until the mixture is warm to the touch and the sugar granules have completely dissolved. You can test this by rubbing a small amount of the mixture between your fingers – it should feel perfectly smooth. If you are using a thermometer, aim for a temperature of around 160℉ (71℃).
- Once the sugar has dissolved and the mixture is warm, immediately transfer it to the bowl of a stand mixer fitted with the whisk attachment (or use a handheld mixer). Begin whipping on medium speed for about a minute, then increase to high speed and continue whipping until stiff, glossy peaks form. When the meringue is ready, it should be firm enough that the bowl can be inverted without any movement or sliding of the meringue. Finally, add the vanilla extract or paste and mix briefly to combine.
- Once your meringue is prepared, you can pipe it onto the cooled tart in any decorative pattern you desire. Gently toast with a kitchen torch for a beautiful finish, if desired.
Notes
This beautiful tart can be stored in an airtight container in the refrigerator for up to 5 days, maintaining its delightful texture and flavor.
The success of this recipe heavily relies on the quality of your white chocolate. For optimal results and a perfectly set, firm ganache, I strongly recommend using high-quality brands like Callebaut white chocolate chunks or Valrhona white chocolate feves. Based on testing, brands like Ghiradelli have not yielded sufficiently firm results for this particular ganache recipe. Investing in premium white chocolate truly makes a difference here.
