Press hash browns between paper towels to remove excess moisture. Grease a 9-in. pie plate with 2 teaspoon butter. Press hash browns onto the bottom and up the side of the plate. Drizzle with remaining butter. Bake, uncovered, at 425 for 20-25 minutes or until edges are browned.
Combine cheeses and ham; spoon into the crust. Press down. In a bowl, beat the eggs, cream and seasoned salt, pour over ham. Reduce heat to 350. Bake, uncovered for 20-25 minutes or until a knife inserted near the center comes out clean. Let stand for 10 minutes before cutting.
