Creole Crawfish Pie

Roll out each piecrust on a lightly floured work surface into a 12-inch round. Transfer 1 dough round to a 9-inch pie plate, pressing dough into corners and up sides of plate and leaving a 1-inch overhang. Transfer second dough round to a parchment-lined baking sheet. Place both crusts in refrigerator to chill until ready to use, at least 15 minutes or up to 1 day (covering with plastic wrap if chilling longer than 3 hours).

Melt 1/4 cup butter in a large skillet over medium-high. Reduce heat to medium, and gradually whisk in flour. Cook, stirring constantly, until roux is slightly thickened and turns the color of peanut butter, 4 to 6 minutes. (Relax, have a sip of wine, and enjoy this process. If you can make a roux, you’ve mastered the key to good Creole cuisine.)

Add onion, bell pepper, celery, and garlic to roux in skillet; cook over medium, stirring often, until onion is transparent, about 7 minutes. Add crawfish and crawfish fat from package. If your crawfish package does not have fat, add 2 tablespoons butter to the skillet. Cook, stirring often, until crawfish tails curl up, about 3 minutes. Add condensed cream of mushroom soup, and slowly stir until combined. Bring mixture to a simmer over medium; reduce heat to low. Simmer, stirring occasionally, until flavors are fully incorporated, about 5 minutes.

Add sugar, Creole or Cajun seasoning, onion powder, basil, rosemary, and garlic powder to crawfish mixture in skillet, and stir until incorporated. Taste and add additional Creole seasoning, basil, and/or rosemary to taste. Remove from heat. Let cool, uncovered, until mixture is room temperature, 30 minutes to 1 hour. Meanwhile, preheat oven to 400°F with oven rack in lower third position.

Remove chilled piecrusts from refrigerator. Pour crawfish filling (about 4 cups) into prepared piecrust in pie plate. Cover pie with rolled-out piecrust. Using your fingers, press and seal edges together. Trim overhang to about 1/2 inch; fold overhang underneath itself, and crimp decoratively as desired. Whisk together beaten egg and 1 tablespoon water in a small bowl. Lightly brush egg wash over top of piecrust. Using a sharp knife, cut a few small slits into pie top for steam to escape.

Place pie on a baking sheet, and bake in preheated oven until top is golden brown, 40 to 45 minutes. Remove from oven, and let rest about 10 minutes. Garnish with scallions, and serve.
