120g flour
1 teaspoon chopped fresh thyme
9g white sugar
3.5g salt, divided
1 pinch of freshly ground black pepper
300ml milk
3 large eggs
1 tablespoon of lemon zest
2 tablespoons of butter
450g fresh asparagus, trimmed and cut into 5cm pieces
Step 1
Preheat the oven to 175 degrees C (350 degrees F). Grease a 23cm pie dish.
Step 2
In a large bowl, combine the flour, thyme, sugar, 3g of salt, and pepper. Gradually whisk in the milk, then add the eggs and lemon zest, whisking until the batter is smooth.
Step 3
Melt the butter in a heavy skillet over medium heat. Add the asparagus and the remaining 1.5g of salt; cook, stirring occasionally, until the asparagus is vibrant green and coated with butter, for about 1-2 minutes.
Step 4
Transfer the asparagus to the prepared pie dish and pour the batter evenly over the top.
Step 5
Bake in the preheated oven until the flan is puffed and golden brown around the edges, for 40 to 45 minutes.
