This golden onion pie is a magnificent example of rustic home baking, combining a soft, enriched yeast dough with a deeply savoury filling. The secret lies in the slow-cooked onions, which are caramelised until sweet and tender before being folded into a rich custard of soured cream and egg yolks. The addition of finely chopped bacon provides a subtle smoky depth that perfectly offsets the natural sweetness of the onions.
Ideal for a comforting weekend lunch or a seasonal supper, this substantial savoury pie sits somewhere between a classic quiche and a traditional brioche tart. Serve slices while they are still warm from the oven, accompanied by a crisp green salad tossed in a sharp mustard vinaigrette. The richness of the pastry and the creamy filling make it a wonderful centrepiece for any informal gathering.

Ingredients for Golden Onion Pie

1/4 teaspoons sugar
250g plain flour
1/2 teaspoons salt
1 large egg
1/2 stick unsalted butter, melted and cooled
1.6kg onions, thinly sliced

1/2 stick unsalted butter
240ml soured cream
2 large egg yolks

How to make Golden Onion Pie
Stir together yeast, milk, and sugar in bowl of a stand mixer fitted with paddle attachment (or in a bowl to mix by hand) and let stand until foamy, about 5 minutes. (If mixture doesn't foam, start over with new yeast.)
Add flour, salt, egg, and butter and mix at low speed (or stir) until a dough forms. Increase speed to medium-high and beat 3 minutes (or knead by hand 5 minutes).
Sprinkle dough lightly with flour and cover bowl with a kitchen towel (not terry cloth). Let dough rise in a draft-free place at warm room temperature until doubled, 1 1/2 to 2 hours.
Cook onions and bacon in butter with 1 teaspoon salt and 1/2 teaspoons pepper in a 12-inch heavy skillet, covered, over medium-high heat, stirring occasionally, until onions are softened, about 20 minutes.
Remove lid and cook, stirring occasionally, until onions are golden, 20 to 30 minutes. Cool onions.
Whisk together soured cream and yolks, then stir into onions.
Preheat oven to 191°C with rack in middle.
Roll out dough on a lightly floured surface with a lightly floured rolling pin into a 12-inch round. Fit dough into springform pan (stretching slightly if necessary to hang over edge) and spread filling evenly in it. Fold edges of dough over filling, leaving some filling exposed in centre. Let pie stand 20 minutes at room temperature.
Bake until crust is golden-brown and filling is bubbling, about 11/4 hours. Cool slightly before serving.
