**Preheat Oven:** Preheat your oven to 250°F (120°C). Line a baking sheet with parchment paper or a silicone baking mat.

**Prepare Seasoning:** In a mixing bowl, combine melted butter, ranch seasoning mix, Parmesan cheese, garlic powder, and smoked paprika. Stir until well blended.

**Coat Crackers:** Add the oyster crackers to the bowl and toss until evenly coated with the butter mixture.

**Bake:** Spread the coated crackers in a single layer on the prepared baking sheet. Bake for 15–20 minutes, stirring halfway through, until the crackers are golden and crispy.

**Cool:** Remove from the oven and let cool completely before serving.
