First spray the bottom of your 9 x13 pan with pam. Then add onion flakes to liking. I coated the entire bottom very well and then some. Take your ground beef and lightly spread while smashing down over the onion flakes to cover your entire pan. Season the top with your seasoning. Just one sprinkle evenly all over ground beef. Bake at 400 for about 20 minutes. Then take it out, and add six slices of cheese and put back in oven to melt about 5 minutes. Take out and cut in 24 pieces. 6 rows of 4 should do it. Serve with pickles and ketchup for the traditional White castle style. Enjoy!
