Preheat the oven to 250°F.

Place the melted butter, Worcestershire sauce, and dry ranch mix in a small bowl and stir until well combined.

Pour the Chex cereals, Cheez-Its, pretzels, and oyster crackers onto a rimmed baking sheet and drizzle with the seasoned butter. Mix well.

Bake for 45 minutes in the preheated oven, stirring every 15 minutes.

Remove the pan from the oven and allow the mixture to cool to room temperature before storing it in an airtight container.
