Tarte aux bleuets — wild blueberry pie — is Quebec’s summer dessert, made with the small, intensely flavored wild blueberries that carpet the province’s northern regions. In a flaky, buttery crust, they bubble up into a deep purple, jammy filling that tastes like the boreal forest in a slice. It is the pie of roadside stands, family cottages, and every Quebecois grandmother’s summer table.
Why this recipe works: The filling is simple — wild blueberries, sugar, a squeeze of lemon, and just enough thickener to set the juices into a glossy jam. The berries’ natural intensity means the pie needs almost nothing else. A lattice top lets the steam escape and shows off the jewel-toned filling.
Key ingredients
- Wild blueberries: fresh in summer; frozen wild berries work beautifully year-round.
- Sugar and lemon juice: balance for the tart berries.
- Cornstarch or tapioca: the thickener — tapioca gives the clearest set.
- A flaky double crust: butter-based, with a lattice top.
Tips for the perfect blueberry pie
Toss the berries with sugar, lemon, and thickener, and let them sit for 15 minutes while you roll the dough. If using frozen berries, add them frozen and extend the baking time by 10 minutes. Bake at 425°F for 20 minutes, then 375°F until the filling bubbles thickly through the vents, 45 to 55 minutes total. Cool completely — at least 4 hours — before slicing, or the filling will run.
Variations and storage
Add a pinch of cinnamon or a spoonful of maple syrup to the filling for a Quebecois touch, or crown the pie with vanilla ice cream. The pie keeps 2 to 3 days at room temperature or 5 days in the fridge, and freezes well for 3 months.
