Preheat oven to 425º F.

Press thawed hash browns between paper towels to remove moisture. Fit hash browns into greased 10-inch pie plate, forming a solid crust. Brush crust and top edges with melted butter. Bake for 25 minutes. Remove from oven.

Reduce oven temperature to 350º F.

Sprinkle cheeses and ham evenly over bottom of crust. Beat half and half with eggs and seasoned salt. Pour over cheeses and ham. Bake uncovered for 30 to 40 minutes, or until a knife inserted in center comes out clean. Yield: 4 servings.
