👨‍🍳 作り方

1. 1

   Preheat your oven to 375°F (190°C).

   💡 プロのコツ: Ensuring the oven is preheated will help the pastry cook evenly.
2. 2

   In an oven-safe skillet (about 9-10 inches in diameter), melt the butter over medium heat. Sprinkle the sugar over the melted butter and cook, stirring, until it forms a light caramel. Be careful not to burn it.

   💡 プロのコツ: Watch the caramel closely; it can go from golden to burnt very quickly.
3. 3

   Add the sliced shallots to the skillet. Cook over medium-low heat, stirring occasionally, until they are softened and lightly caramelized, about 15-20 minutes. If using tomatoes, add them during the last 5 minutes of cooking.

   💡 プロのコツ: Low and slow cooking is key to caramelizing the shallots without burning them.
4. 4

   Stir in the thyme leaves, salt, and pepper. Arrange the shallots and tomatoes evenly in the skillet.

   💡 プロのコツ: Taste and adjust seasoning as needed.
5. 5

   Unroll the puff pastry sheet and place it over the vegetables in the skillet, tucking the edges down around the sides.

   💡 プロのコツ: Gently press the pastry edges down to seal them around the vegetables.
6. 6

   Bake for 25-30 minutes, or until the pastry is golden brown and puffed.

   💡 プロのコツ: Keep an eye on the pastry to ensure it doesn't over-brown.
7. 7

   Let the tarte cool in the skillet for about 10 minutes. Carefully invert a serving plate over the skillet and quickly flip them over together to unmold the tarte onto the plate.

   💡 プロのコツ: Be cautious as the skillet and caramel will be very hot.
8. 8

   Drizzle with balsamic glaze, if desired, and serve warm.

   💡 プロのコツ: This tarte is delicious served with a simple green salad.
