An Alsatian apple tart in which sliced apples are arranged in a pastry shell and bound by a migaine — the regional egg-and-cream custard — poured over before baking so the fruit half-bakes, half-poaches in the setting cream. The result sits between a fruit tart and a flan: tender apple, a pale set custard, and a short buttery crust. It is the everyday Sunday dessert of Alsatian homes and bakeries, dusted with sugar or cinnamon and eaten just warm. The migaine is the same egg-cream binder used in the savoury tarte flambée and quiche of the region, here turned to a sweet end.
The tarte Alsacienne belongs to the apple-baking tradition of Alsace, an orchard region of the upper Rhine where apples and other tree fruit have long been baked into custard-set tarts. Its defining element is the migaine, the Alsatian dialect term for the egg-and-cream mixture poured over the filling — the same binder that, unsweetened, sets the cheese-and-cream topping of tarte flambée and the custard of a Lorraine-Alsace quiche. Rather than a dated invention, it is a regional home and bakery standard, one of a family of Alsatian custard fruit tarts made equally with plums (quetsches), rhubarb, blueberries or cherries in their seasons. As a traditional regional preparation, no single origin date is reliably documented.
The crust shatters short and buttery at the rim, softening where the custard has soaked in. The apples are tender, almost translucent, holding their slices but yielding to a fork, faintly tart against the sweet pale custard that has set soft and barely trembling around them. A dusting of cinnamon-sugar on top adds warmth and a whisper of spice. It is gentle and homely — milky, fruity, lightly sweet — best eaten just warm so the custard is at its silkiest, with the apples still carrying a little of the orchard's acidity.
The migaine is a baked custard: eggs provide the proteins that coagulate and set the cream as it heats, turning a liquid pour into a soft, sliceable layer. The ratio matters — enough egg to set, enough cream to stay tender; too many eggs and it firms like a quiche, too few and it never sets around the fruit. Baking at a moderate temperature lets the custard coagulate gently without curdling or puffing, while the apples, half-submerged, soften and release a little juice into the cream. Pre-baking or par-cooking the apples is optional but keeps the tart from going watery, and a short blind-bake of the shell guards the base against the wet custard.
Variations
The same custard tart is made through the year with the region's other fruit — quetsche plums (the most iconic Alsatian version), rhubarb, blueberries (myrtilles), cherries or pears — the migaine staying constant while the fruit changes. Some recipes flavour the custard with vanilla, kirsch or cinnamon; some thicken it with a spoon of ground almonds or semolina to hold juicier fruit. A plainer Alsatian apple tart skips the custard entirely for a simple glazed fruit tart, but the migaine-set version is the one called tarte Alsacienne par excellence.

How it's made
7 steps · 35 min active + 55 min waiting
- 120 min
Line a tart tin with short pastry and chill, then blind-bake briefly to set the base.
Watch outBlind-bake the shell just to set it — a par-baked base stays crisp under the wet custard; skip it and the bottom goes soggy.
- 210 min
Peel, core and slice the apples evenly.
- 38 min
Arrange the apple slices in a close pattern over the pre-baked shell.
- 45 min
Whisk the eggs, cream, sugar and a little vanilla into the migaine.
- 53 min
Pour the custard evenly over the apples, filling the gaps without overflowing.
- 640 min
Bake at a moderate heat until the custard is just set and the apples are tender.
Watch outBake at moderate heat only until the custard is just set — too hot and it curdles and puffs; pull it while the centre still has the faintest wobble.
- 75 min
Dust with cinnamon-sugar and cool slightly; serve just warm.
