Let’s dive in and make some magic happen with these sourdough blueberry brioche tarts!
Ingredients for Sourdough Blueberry Brioche Tarts
Sourdough Brioche Dough:
- 250g all-purpose flour (or bread flour for more chew)
- 50g sugar (can swap for coconut sugar or brown sugar)
- 5g salt
- 2 large eggs, room temperature
- 100g unsalted butter, softened (can use margarine for budget-friendly)
- 80g active sourdough starter (100% hydration)
- 50ml whole milk, warm
Blueberry Filling:
- 250g fresh or frozen blueberries (if frozen, thaw and drain excess juice)
- 50g sugar (adjust sweetness depending on blueberries)
- 1 tbsp cornstarch (helps thicken the filling)
- 1 tsp vanilla extract
- Zest of 1 lemon (adds brightness)
Egg wash:
- 1 egg, beaten with 1 tbsp water
Swaps & Tips:
- For a dairy-free option, use plant-based milk and butter substitutes.
- If you want to stretch ingredients, reduce sugar in the dough and increase in the filling for extra fruitiness.
- Use wild blueberries for more intense flavor, or mix berries for variety.
Step-by-Step Instructions for Perfect Sourdough Blueberry Brioche Tarts
1. Mix the Dough (15 mins active, plus rising time)
In a large bowl, combine the flour, sugar, and salt. In a separate bowl, whisk the eggs, milk, and sourdough starter. Slowly pour liquids into the dry ingredients and mix until roughly combined. Add the softened butter in chunks, then knead by hand or mixer for about 10 minutes until the dough is smooth, elastic, and slightly sticky. A good test is to gently pull the dough – it should stretch without tearing.
Mistake alert: Not kneading long enough will produce dense brioche with no lift.
2. Bulk Fermentation (4–6 hours at room temp or overnight in fridge)
Cover dough with a damp towel or plastic wrap. Let it rise until doubled—time varies with starter strength. You want to see bubbles forming on the surface as proof of fermentation.
Tip: A cooler rise develops flavor, so overnight in fridge is perfect.
3. Make Blueberry Filling (10 mins)
Combine blueberries, sugar, cornstarch, vanilla, and lemon zest in a saucepan. Cook over medium heat, stirring often until mixture thickens and berries burst (about 5 minutes). Let cool.
Sensory cue: The filling smells sweet and tangy, thick but still juicy.
4. Shape the Tarts (30 mins)
Roll out dough on a floured surface to about ½ inch thick. Cut into rounds that fit your tart pans (roughly 3-4 inch diameter). Gently press dough into pans, making sure edges are even. Spoon blueberry filling into each tart without overfilling. Cover loosely with a cloth and let tarts rest while oven preheats.
5. Bake (18–22 minutes at 375°F/190°C)
Brush the dough edges with the egg wash for a golden finish. Bake until crusts are puffed, golden, and filling is bubbling. If edges brown too quickly, cover with foil.
Mistake alert: Underbaking yields soggy bottoms; ensure crust is firm and golden.
6. Cooling & Serving (at least 20 minutes)
Remove tarts from pans carefully, let cool on wire racks. The blueberry filling will be hot and slightly runny at first but will set as it cools.
Presentation and Serving Suggestions for Sourdough Blueberry Brioche Tarts
Serve these tarts warm or at room temperature for the best flavor. The brioche tart crust is buttery and tender, perfect for savoring slowly with a cup of Earl Grey or a fresh pot of coffee. For brunch, plate the tarts with a dollop of lightly whipped cream or a spoonful of crème fraîche — their tang intertwines beautifully with the sweet blueberry filling. You can also drizzle with a little honey or dust with powdered sugar for added charm.

FAQs About Sourdough Blueberry Brioche Tarts
Q1: Can I use regular yeast instead of sourdough starter?
Yes, but the flavor will be less complex. Replace the sourdough starter with 7g instant yeast and reduce rising time since yeast works faster.
Q2: My dough is too sticky to handle. What can I do?
Lightly flour your surface and hands, but avoid adding too much flour which can dry out the dough. Also, chill the dough for 20 minutes to firm it up.
Q3: How do I know when the dough has properly risen?
It should roughly double in size and feel airy with bubbles visible through the stretched dough surface.
Q4: Can I prepare the dough or filling ahead of time?
Absolutely! Dough keeps well refrigerated overnight. Filling can be made a day ahead and refrigerated; just stir before use.
Q5: My filling is too runny after baking. How to fix?
Be sure to cook blueberry filling thick enough before filling the crust. Add thickener like cornstarch or reduce fruit juice by simmering longer.
Q6: What if I don’t have tart pans?
Mini muffin tins or ramekins work fine; adjust portion size but keep thickness consistent.
Q7: Can I freeze these tarts?
Yes, fully baked and cooled tarts freeze well up to 2 months. Reheat them in a warm oven for 10-15 minutes before serving.
