Melt butter in a large skillet over medium-low heat. Add panko and toast until golden brown, about 3-4 minutes.
Reserve some panko and chopped pickles for topping, and add the remaining panko, chopped pickles, sour cream, ranch seasoning, and pickle juice to a bowl and stir to combine.
If you are serving immediately, top with chopped pickles, toasted panko, and dill.
If you are serving later in the day, store it in an airtight container in the fridge without the toppings. When you are ready to serve, transfer to a serving bowl and add the pickles, panko, and dill.
Notes
Store this fried pickle dip in an airtight container in the fridge for up to 4 days.
If making ahead of time, reserve some toppings on the side to add when you serve. You may need to refresh the dip by stirring in a bit of extra pickle juice.
Serve with chips, pretzels, cucumbers, carrots or celery.
