Preheat your oven to 350°F (180°C) with the rack positioned in the center.

Generously butter an 8 to 9-inch baking dish to prevent sticking.

In a mixing bowl, whisk together milk, sugar, eggs, and vanilla extract until smooth. Gradually add flour and kosher salt.

Arrange hulled and halved strawberries evenly at the bottom of the baking dish.

Pour the creamy batter gently over the strawberries, ensuring they are fully covered.

Place the dish in the preheated oven and bake for about 1 hour.

Carefully transfer the baked flaugnarde to a wire rack to cool before serving.
