👨‍🍳 作り方

1
Preheat oven to 200°C (400°F). Line a 23-25 cm (9-10 inch) tart pan with the shortcrust pastry. Prick the base with a fork.
💡 プロのコツ: Blind baking the crust for 10-12 minutes until lightly golden can prevent a soggy bottom.
2
In a large skillet, melt the butter with the olive oil over medium-low heat. Add the thinly sliced onions and cook slowly, stirring occasionally, until they are very soft, translucent, and lightly caramelized. This can take 20-30 minutes. Season with salt and pepper.
💡 プロのコツ: Cooking the onions slowly is key to developing their sweetness and preventing bitterness.
3
In a separate bowl, whisk together the eggs, heavy cream, and milk. Season with salt, pepper, and a pinch of freshly grated nutmeg.
💡 プロのコツ: Ensure the nutmeg is freshly grated for the best aroma and flavor.
4
Spread the softened, caramelized onions evenly over the pastry base. If using, scatter the cooked lardons over the onions.
5
Carefully pour the egg and cream mixture over the onions and lardons, ensuring it fills the tart evenly.
💡 プロのコツ: Pour slowly to avoid disturbing the onion layer too much.
6
Bake in the preheated oven for 30-40 minutes, or until the filling is set and the top is golden brown. The center should be just set, not liquid.
💡 プロのコツ: A slight wobble in the center is okay, as it will continue to set as it cools.
7
Let the tart cool slightly in the pan for about 10-15 minutes before slicing and serving. It can be served warm or at room temperature.

💡 プロのコツ

✓For an authentic Alsatian flavor, consider adding a pinch of caraway seeds to the onions while they cook.
✓If you don't have shortcrust pastry, a puff pastry can also be used, though it will result in a lighter, flakier tart.
✓This tart is excellent served with a simple green salad.
