In a mixing bowl, add flour and salt. Mix until well combined.

Add the butter and mix until the mixture resembles crumbs.

Add cold water one tablespoon at a time. Mix until it forms a ball.

Using a cling wrap, wrap the ball and refrigerate for 4 hours.

Preheat the oven to 350°F.

After 4 hours, place the ball on a floured surface.

Roll the dough out to fit a 10-inch pie plate. Place the crust in the pie plate and press the dough evenly into the bottom and sides of the pie plate. Use a fork to poke the bottom of the crust. Bake for 3 minutes.

In a microwave-safe bowl, add cream cheese and ½ cup of Parmesan cheese. Microwave for 30 seconds. Mix the cheeses until well combined. Spread this over the par-baked pie crust.

Then, add the ham cubes.

In a medium bowl, whisk eggs, heavy cream, scallions, and salt. Pour this over the ham.

Place the asparagus on top. Sprinkle remaining Parmesan cheese. Bake for 45-48 minutes until eggs are set.

Remove from the oven and allow it to cool for 10 minutes before slicing.
