Form your patties so they are ¼ to ⅓ of an inch wider than the diameter of the buns you'll be serving them on. For a 6-ounce patty, they will end up between ⅓ and ½ inch thick. Season your patties with salt and pepper, then place them on a baking sheet. Refrigerate your patties for 10-15 minutes.
While the patties chill in the refrigerator, preheat your grill or stovetop griddle over medium-high heat.
Grill the burger patties to your desired doneness, about 4-5 minutes per side for medium-rare and 9-10 minutes for well-done. In the final minute of grilling, add a slice of cheese to each patty and cover with a lid to help the cheese fully melt.
Buns
Lightly spread butter on each cut side of the burger bun. Make sure to spread it to the edges.
On a griddle over medium-high heat, place the buttered side of the buns and cook for 1-2 minutes, until golden brown.
Burger Assembly
Remove the pickle slices from their liquid and let them drain on a piece of paper towel. This will help prevent your bun from getting soggy.
Spread mustard evenly on the top half of each burger bun and set aside.
On the bottom bun, add the diced onion,s then the cooked burger. Place 3-4 pickle slices on top of the burger patty, then top with the mustard-coated top bun.
