Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish thoroughly with butter or nonstick spray to prevent sticking and ensure easy cleanup.

In a large skillet over medium heat, cook pork sausage, breaking it into crumbles with a spatula. Stir often until sausage is cooked through and no pink remains, about 8 minutes. Drain excess grease completely.

Evenly spread thawed hash browns into the prepared baking dish. Scatter cooked, drained sausage over the hash browns for an even layer.

In a mixing bowl, combine the sausage gravy mix with milk, whisking vigorously until completely smooth without lumps. Pour evenly over the sausage and hash browns to coat every part.

Sprinkle shredded sharp cheddar cheese across the surface to form an even layer. Press gently with your hand to set the cheese into the gravy.

Open the can of refrigerated biscuits and cut each biscuit into 4 equal pieces. Arrange biscuit pieces evenly over the top, overlapping slightly to cover the entire surface.

Bake in the preheated oven for 25–30 minutes or until biscuits are puffed and deep golden brown. Allow the casserole to rest for 5 minutes before serving to help set the layers.
