In a mixing bowl, combine the flour, paprika, salt, and black pepper.
Dip the onion rings into the buttermilk and then coat them with the seasoned flour mixture.
Heat oil in a deep fryer or a large pot to 350°F (175°C).
Fry the coated onion rings in batches until they are golden brown and crispy. Remove them from the oil and drain on paper towels.
Prep the Cheeseburger:
Mix together the ground beef, steak seasoning, and Worcestershire sauce. Form into even patties.
Heat a grill or grill pan over medium heat.
Add the patties to the grill and cook on both sides, achieving the desired doneness using a thermometer. When the burger is ¾ of the way cooked to your liking, add the cheese and cook until melted.
Assemble the Burger:
Spread your favorite condiments on the inside of the bun.
Place the patty on the bun with lettuce, tomato, and onion.
Serve: Enjoy your cheeseburger with onion rings and a cold cola.
