Heat the oven to 350°F (176°C).
Prep the ingredients per the instructions above.
Soak the fries in cold water for 20 minutes. Then drain and dry well.
Mix together the ground beef, steak seasoning, and Worcestershire sauce. Form into even patties. Transfer to a plate, cover with plastic wrap, and reserve in the fridge until you are ready to cook (see note).
Cook the fries in an air fryer according to the instructions.
Lightly toast the buns in the oven or a toaster oven.
Heat a skillet over medium-high heat.
Cook the burger patties: add the patties to the heated skillet and cook on both sides, getting a nice crusty char to the desired doneness (see note) using a thermometer. When the burger is 3/4 of the way cooked to your liking, add the cheese and cover it with a lid to melt.
Compose the burger: Layer the bun with lettuce, burger, tomato, and onion. Serve with your favorite condiment.
Serve: Enjoy the cheeseburger with french fries, ketchup, pickle, and lemonade.
