Hamburger Hash Browns

Preheat oven to 350 degrees F (175 degrees C).

Grease a 9-inch square baking dish.

Mix hash brown potatoes, vegetable oil, and black pepper in a bowl; press into the bottom of the prepared baking dish.

Heat a large skillet over medium-high heat.

Cook and stir beef, garlic powder, and onion powder in the hot skillet until beef is browned and crumbly, 5 to 7 minutes; drain and discard grease.

Mix water and gravy mix into the cooked beef; bring to a boil.

Reduce heat, cover skillet, and simmer until water evaporates, about 5 minutes.

Fold in 1/2 cup Cheddar cheese.

Spoon beef mixture onto the potato crust.

Bake in the preheated oven for 15 minutes.

Sprinkle remaining 1/2 cup Cheddar cheese and bake until cheese is lightly browned, about 5 more minutes.
