Pre-heat oven to 400 degrees Fahrenheit.
Line medium baking sheet with parchment paper or aluminum foil and set aside.
Drain 12 pickle chips on a paper towel and pat dry.
Combine egg and water in one bowl and beat well.
Combine flour and cayenne in a second bowl.
Place panko bread crumbs in a third bowl.
Dip pickle slices into egg mixture, then the flour mixture, then the panko; then place in a single layer on the prepared baking sheet.
Bake pickles for 25-30 minutes, flipping once halfway through, until golden brown. Remove from oven and set aside to cool.
Season beef with salt and pepper, then form into 4 slider-sized patties (3-4 oz. each).
Grill burger patties to desired level (e.g. medium, medium-well, etc.); let rest for 1-2 minutes.
To assemble each burger, squeeze desired amount of ranch dressing on bottom bun, then top with red onion slices. Add burger patty and fried pickles. Top with top bun and enjoy!
