Preheat oven to 425°F or 220°C, line a baking sheet with foil, and place a wire rack on top.
Pat chicken wings completely dry with paper towels.
Toss wings with olive oil until lightly coated.
Mix ranch seasoning, dill, garlic powder, onion powder, smoked paprika, salt, and black pepper.
Season wings thoroughly with the spice mixture.
Arrange wings in a single layer on the wire rack with space between.
Bake 40–45 minutes, flipping halfway, until deeply golden and crispy.
Brush hot wings lightly with dill pickle juice.
Serve hot with ranch dressing and optional fresh dill.
