3heaping cups(500grams)blueberriesfresh (just over 1 lb)
1½tablespoons(12grams)cornstarch
1½tablespoons(20grams)sugar
1teaspoon(1teaspoon)vanilla extract
Prep the oven and pan: Preheat to 350°F (180°C). Oil and flour a tart pan or line it with parchment. Using a pie dish? Oil it and lay two criss-crossed strips of parchment for easy lifting.
Make the dough: Mix 1 teaspoon lemon zest, ⅓ cup sugar, ¼ cup olive oil, and ¼ cup water in a bowl.In another bowl, mix 1½ cup all-purpose flour, 1 pinch salt, and 1 teaspoon baking powder.Combine wet and dry just until a dough forms—don’t overmix. Press into a ball (no kneading needed).
Shape the crust: Press the dough into the pan, covering bottom and sides. Prick with a fork to prevent bubbling.
Add the filling: Rinse 3 heaping cups blueberries, then toss with 1½ tablespoons cornstarch, 1½ tablespoons sugar, 1 teaspoon vanilla extract, and optional lemon zest. Spread evenly into the tart shell.
Bake and serve: Bake for 30 minutes, until crust is golden. Cool for 20–30 minutes. Serve with extra lemon zest, whipped cream, or vanilla ice cream.
SUBSTITUTIONS
Flour → Use spelt, oat, or 1:1 gluten-free flour.
Sugar → Swap with brown or coconut sugar.
Oil → Any neutral oil works, or use melted vegan butter.
Cornstarch → Try arrowroot or tapioca starch.
Lemon zest → Sub with orange zest for a twist.
Vanilla extract → Almond extract works too (use half the amount).
TIPS
Use fresh blueberries for less juice and no soggy crust.
Skip lemon juice—use zest for fresh flavor without the extra liquid.
Don’t overmix the dough—just press it together gently.
Cold water = tender crust, perfect for a dairy-free tart.
Prick the crust with a fork to prevent bubbling.
Cool before slicing so the filling sets properly.
Top with lemon zest after baking for extra zing.
Make it your way: Try whole-wheat or gluten-free flour.
Serve plain or fancy with whipped cream or ice cream.
STORAGE
Store the tart at room temperature for 1 day, in the fridge for up to 3 days, or freeze it for up to 2 months—just wrap it well to keep it fresh.
