1 Â Â bunch asparagus, trimmed and chopped into 3-in (7 cm) pieces
2 Â Â teaspoons kosher salt, divided
2 Â Â teaspoons freshly ground black pepper, divided
8 Â Â tablespoons unsalted butter
2 cups   all-purpose flour (250 g)
½   teaspoon baking powder
¾ cup   grated parmesan cheese, divided (80 g)
¼ cup   cold water (60 mL)
⅓ cup   sour cream (75 g)
⅔ cup   half & half (160 mL)
1 ½   cups shredded cheddar cheese (150 g)
1 cup   cherry tomato, halved (200 g)
Preheat   the oven to 375˚F (190˚C).
Heat a   drizzle of olive oil in a 10-inch (25 cm) cast-iron skillet over medium   heat. Add the asparagus, ½ teaspoon salt, and ½ teaspoon pepper. Sauté for   5-6 minutes, until the asparagus is bright green but still firm. Turn off   the heat. Transfer the asparagus to a bowl and set aside to cool.
Add   the butter to the hot skillet and let it melt from the residual heat.   Allow the pan to cool with the butter in it.
Once   the cast iron is mostly cooled (warm to the touch is okay), add the flour,   ½ teaspoon salt, 1 teaspoon black pepper, baking powder, and ½ cup   Parmesan cheese, stirring with a spatula until the texture is sandy. Add   the water and stir to combine. Using your hands, press the dough evenly   over the bottom and about 2 inches (5 cm) up the sides of the pan. Use a   fork to crimp the edges of the dough against the side of the pan. Set   aside.
Add   the eggs and sour cream to a medium bowl. Whisk to combine. Add the   half-and-half, remaining teaspoon of salt, and remaining ½ teaspoon pepper   and whisk until fully incorporated.
Scatter   the cheddar cheese evenly over the crust. Arrange the asparagus over the   cheese. Sprinkle the remaining ¼ cup (25 G) Parmesan evenly over the   asparagus. Slowly pour the egg mixture into the skillet. Do not overfill.   Top with the cherry tomatoes, cut sides up.
Carefully   transfer the quiche to the oven and bake for 45-50 minutes, until the   center is set and the edges are golden. Let cool for at least 30 minutes   before serving.
Serve   the quiche straight from the pan. Note: Use a spatula to cut, instead of a   knife, so as not to scratch your pan.
