17 - 1 teaspoon salt
18 - 6 tablespoons cold unsalted butter, cubed
19 - 3/4 cup cold buttermilk
20 - 1 large egg, lightly beaten for egg wash
# Directions:
01 - Preheat oven to 400°F.
02 - In a large skillet or Dutch oven, melt butter over medium heat. Add onion, carrots, and celery, sautéing for 6 to 8 minutes until vegetables are softened. Add minced garlic and cook for 1 additional minute.
03 - Sprinkle flour over the vegetables and cook, stirring constantly, for 1 to 2 minutes until flour is fully absorbed.
04 - Gradually whisk in chicken broth and milk, stirring continuously. Bring mixture to a simmer and cook for 3 to 4 minutes until sauce thickens.
05 - Stir in diced chicken, frozen peas, thyme, salt, and pepper. Remove from heat.
06 - Pour filling into a 9x13-inch baking dish or large pie dish.
07 - In a large mixing bowl, whisk together flour, baking powder, baking soda, and salt. Add cold butter cubes and cut in using a pastry blender or fingertips until mixture resembles coarse breadcrumbs.
08 - Add cold buttermilk and gently stir until just combined, being careful not to overmix the dough.
09 - Drop spoonfuls of biscuit dough evenly across the surface of the filling. Brush tops with beaten egg if desired for a glossy finish.
10 - Bake for 25 to 30 minutes until biscuits are golden brown and filling is bubbling at the edges.
11 - Allow pot pie to rest for 5 to 10 minutes before serving.
