Creating your own White Castle hamburgers copycat version can be accomplished with these simple steps:

1. Prepare the Pan: Preheat a griddle or skillet over medium heat.
2. Mix Ingredients: In a large bowl, combine ground beef, chopped onion, salt, pepper, garlic powder, onion powder, and Worcestershire sauce. Mix until well blended.
3. Shape Patties: Divide the mixture into 12 equal portions. Flatten each portion into thin patties—similar to the original White Castle burger size.
4. Cook Patties: Place the patties onto the heated griddle. Cook for about 2-3 minutes on one side, then flip.
5. Add Cheese: If using cheese, place a slice on each patty after flipping. Cook for an additional 2-3 minutes until the cheese is melted and patties are cooked through.
6. Prepare Buns: While the patties are cooking, lightly toast the slider buns on the griddle until golden brown.
7. Assemble the Sliders: Place each cooked patty on a bottom bun. Top with pickles and the top bun for the perfect slider.
8. Serve: Arrange the burgers on a platter for easy serving and enjoy!

Following these steps will make the process enjoyable and rewarding, resulting in delicious copycat sliders that everyone will adore.
