Ingredients:
- 2 cups All-Purpose Flour
- 1 tablespoon Baking Powder
- 1 teaspoon Salt
- 1/2 cup (113g) very cold Unsalted Butter, cubed
- 3/4 cup cold Buttermilk
- 1 pound Ground Pork Sausage
- 1/4 cup All-Purpose Flour
- 3 cups Whole Milk
- 1 1/2 teaspoons freshly ground Black Pepper
- 1/2 teaspoon Salt
- 1 large Egg (for wash, optional)
- 1 tablespoon Milk or Water (for wash)
Instructions:
- Preheat oven to 425°F (220°C). Lightly grease a 9x13 inch baking dish.
- Make the Biscuit Dough: In a bowl, whisk together 2 cups flour, baking powder, and 1 teaspoon salt. Cut in the cold butter using a pastry blender until the mixture resembles coarse crumbs. Gradually add the cold buttermilk, mixing until just combined. Do not overmix.
- Shape Biscuits: Turn dough onto a lightly floured surface. Pat or lightly roll to about 3/4-inch thickness. Cut into 9 to 12 rough squares or rounds.
- Cook the Sausage: Brown the ground pork sausage in a large, deep skillet over medium heat, breaking it up as it cooks. Drain off all but 2 tablespoons of the rendered fat.
- Make the Roux: Sprinkle 1/4 cup flour over the sausage and reserved fat. Cook, stirring constantly, for 1 minute.
- Form the Gravy: Gradually whisk in the cold milk until smooth. Bring to a simmer, stirring occasionally, until the gravy thickens enough to coat the back of a spoon (about 5-7 minutes).
- Season the Gravy: Remove from heat. Stir in 1 1/2 teaspoons of black pepper and 1/2 teaspoon of salt. Taste and adjust seasoning as necessary.
- Assemble the Casserole: Pour the hot sausage gravy evenly into the bottom of the prepared 9x13 inch baking dish.
- Top with Biscuits: Arrange the raw biscuit pieces evenly over the top of the gravy, allowing them to touch. Brush lightly with the egg wash if using.
- Bake for 25–30 minutes, or until the biscuits are puffed, golden brown, and cooked through.
- Rest and Serve: Let the Biscuits and Gravy Casserole rest for 5 minutes before serving warm.
