In a large skillet over medium high heat break up and brown ground beef until no longer pink. Drain any excess grease.
Season with salt, black pepper and garlic powder.
Mix butter and flour into ground beef until butter melts and flour is well incorporated. Cook for 1 minute to cook the raw taste out of the flour.
Stir in milk, french onion soup, and cream of soup until well combined.
Add in O'brien style potatoes and mix well.
Stir in 4oz shredded cheese.
Turn burner down to a medium/medium low. Place lid on and cook 10 minutes. (Every few minutes take lid off and stir to make sure potatoes are not sticking to bottom of skillet.)
After 10 minutes, potatoes should be heated through and mixture should be bubbly. Turn off burner. Sprinkle remaining 4oz of cheese over mixture, place lid on to allow cheese to melt. Sprinkle with dried or fresh parsley. Enjoy.
