1. Preheat the Oven:

1. Preheat your oven to 375°F (190°C). Grease a 9-inch pie dish or casserole dish.

2. Cook the Sausage:

1. In a large skillet, cook the sausage over medium heat until browned and fully cooked, breaking it into crumbles as it cooks.
2. Remove the sausage from the skillet and set it aside, leaving about 2 tablespoons of grease in the pan.

3. Make the Gravy:

1. Add the flour to the skillet with the sausage grease. Stir and cook for 1-2 minutes to make a roux.
2. Gradually whisk in the milk, stirring constantly to avoid lumps.
3. Add the garlic powder, onion powder, salt, and pepper. Cook until the gravy thickens, about 5-7 minutes.
4. Stir the cooked sausage back into the gravy and remove from heat.

4. Assemble the Pie:

1. Pour the sausage and gravy mixture into the prepared pie dish.
2. Place the biscuits on top of the gravy, arranging them evenly.
3. Sprinkle shredded cheddar cheese over the biscuits, if desired.

5. Bake the Pie:

1. Bake in the preheated oven for 15-20 minutes, or until the biscuits are golden brown and cooked through.

6. Garnish and Serve:

1. Let the pie cool for 5 minutes before serving.
2. Garnish with chopped parsley for a fresh touch. Serve warm and enjoy!
