In a large mixing bowl, combine the ground chuck, sour cream, ranch dressing mix, crumbled bacon, and shredded cheddar. Use your hands or a spatula to blend until just mixed; this will take about a minute. Avoid overmixing to keep your Crack Burgers tender.

Divide the mixture into six equal portions. Shape each portion into a patty, about ¾-inch thick, and use your thumb to create a slight dimple in the center of each.

Refrigerate the formed patties for about 15 minutes.

While your patties chill, preheat your grill or a cast-iron skillet over medium heat for about 5 minutes.

Carefully place the patties on the hot grill or skillet, making sure not to overcrowd the surface. Cook for about 4-5 minutes on one side, then flip and cook for an additional 4-5 minutes until they reach your desired doneness.

Transfer the cooked patties to toasted hamburger buns and layer on toppings like lettuce, tomato, mustard, and mayo. Serve immediately.
