INGREDIENTS You Need
This Sourdough Blueberry Brioche Tarts ingredient list is all about bold flavors that actually work together! Here’s exactly what you’ll gather for this delicious magic:
- 1 cup sourdough brioche dough (if you don’t have a starter, store-bought brioche dough works fine too!)
- 1 ½ cups fresh blueberries (or frozen, just thaw and drain for that perfect blueberry filling tart)
- ¼ cup granulated sugar
- 1 tablespoon cornstarch (to thicken that luscious blueberry filling tart)
- 1 teaspoon lemon zest (this gives a fresh, zingy punch)
- ½ teaspoon vanilla extract (adds warmth and depth)
- 1 large egg (for brushing the crust golden)
- 1 tablespoon butter, melted (brush on top for that glossy finish)
- Powdered sugar for dusting (optional but highly recommended!)

No worries if you don’t have cornstarch — arrowroot powder or tapioca starch work wonders as a natural thickener in your Sourdough Blueberry Brioche Tarts.
You can grab all these ingredients during your normal shopping trip, and they’re all flavor boosters that turn this simple fruit tart baking into a celebration of taste.
Quick tip for busy weeknights: prepare your sourdough brioche dough in advance or grab a ready-made one, and the blueberry filling tart can be mixed ahead, saving you precious time.
I love adding extra lemon zest to my Sourdough Blueberry Brioche Tarts for that fresh, springy kick that wakes up the blueberry filling tart like nobody’s business.
This recipe’s ingredient lineup balances tangy, sweet, and buttery notes perfectly — promise you’re going to love it!
Let’s Make Some!
Are you ready to watch the magic happen? These Sourdough Blueberry Brioche Tarts come alive step-by-step, and I’ll be right here cheering you on!
- Prep Your Dough: Roll out your sourdough brioche dough on a floured surface until it’s about ¼ inch thick. I find this thickness perfect for making homemade brioche tartlets that puff up beautifully but still hold that tart filling without sogginess.
- Cut and Place: Use a round cutter (about 3-4 inches in diameter) to cut circles from the dough. Gently press these into a greased tartlet pan or mini muffin tin. This is the part where your homemade brioche tartlets start taking shape!
- Make the Blueberry Filling Tart: In a saucepan, combine your blueberries, sugar, cornstarch, lemon zest, and vanilla extract. Cook over medium heat, stirring regularly, until it thickens into that perfect blueberry filling tart consistency. The smell right now? Absolutely incredible!
- Fill the Tart Shells: Spoon a generous amount of the warm blueberry filling tart into each dough shell. Don’t be shy — we want flavor explosions in every bite.
- Brush and Bake: Whisk your egg with a splash of water and brush the edges of the dough for a golden, glossy finish. Pop those beauties into a preheated 350°F oven and bake for around 18-22 minutes. Your kitchen will smell like a bakery dream.
- Cool and Dust: Let the tarts cool for at least 10 minutes before popping them out. A light dusting of powdered sugar brings that final pop of sweetness and wow factor.
In my kitchen, this whole process usually takes under an hour, which makes these Sourdough Blueberry Brioche Tarts a perfect weeknight winner that doesn’t sacrifice on taste.
