Pour the oyster crackers into a large mixing bowl.
Pour the butter over the crackers and toss to coat.
Sprinkle the ranch seasoning over the crackers and stir to combine.
Spread the crackers in an even layer on a baking sheet and transfer to the oven.
Bake the oyster crackers for 15-20 minutes tossing once halfway through cooking.
Remove the crackers from the oven and allow to cool to room temperature.
Transfer the crackers to an airtight container and store at room temperature or enjoy immediately.
You can make these ranch oyster crackers without baking them, too! Simply spread the crackers in a single layer on a baking sheet and allow to dry at room temperature for 3-4 hours. The baking method is much quick and more efficient for quick snacking!
