01 - In a small bowl, whisk together mayonnaise, sour cream, buttermilk, dill, parsley, chives, garlic powder, onion powder, salt, pepper, and lemon juice. Cover and refrigerate until ready to serve.
02 - In a large bowl, combine drained hash browns, eggs, flour, garlic powder, onion powder, salt, and black pepper. Mix thoroughly until well combined.
03 - Heat vegetable oil in a large skillet over medium heat. Portion approximately 1/4 cup of the hash-brown mixture and shape into round patties, about the size of a slider bun. Fry patties in batches for 3-4 minutes per side until golden brown and crisp. Drain excess oil on paper towels.
04 - In a bowl, whisk together eggs, milk, salt, and pepper. Melt butter in a nonstick skillet over medium-low heat. Pour in the egg mixture and gently scramble until just set.
05 - Place a hash-brown patty on a serving plate. Top with a slice of cheese, a portion of scrambled eggs, two pickle slices, optional red onion and chives, and finally, another hash-brown patty to create a slider. Repeat this process for the remaining ingredients.
06 - Serve the sliders warm. Accompany with the chilled ranch dip, either on the side or drizzled over the sliders.
