Prepare garnishes as desired. Recommend 1 lettuce leaf in halves, 2 thin tomato slices, 3-4 rings of red onion, and 3 pickle chips per burger.
To make the hamburger patties, divide the ground beef as desired into 2 or 4 portions. Roll each into a ball then flatten between palms. Season each flattened patty with salt and pepper.
Heat a large griddle or skillet over medium heat. Lightly butter each half of each bun and place butter-side down on the griddle. Cook until each bun is lightly browned. Place on plates and arrange with garnish.
Heat a large skillet over medium-high heat for 1 minute. Place the hamburger patties onto the skillet, leaving space between them. After 3 minutes, flip the patties. Cook for an additional 2 minutes (or longer, depending on your desired doneness.) If desired, add cheese to each patty. Cover if able to help the cheese melt for approximately 2 minutes. Remove from heat.
Place each patty on a bun and serve.
