In a gallon zip-top bag, combine olive oil, onion powder, garlic powder, ranch seasoning, dill pickle juice, and dried dill. Close and shake to combine.
Add mini saltines to bag, close again, and gently turn bag to coat crackers in seasoning mixture.
Arrange crackers on a rimmed baking sheet and bake until golden brown and oil has absorbed, about 15-20 minutes. Enjoy!
