Preheat your oven to 300°F (150°C).

In a large mixing bowl, combine the pretzels, roasted almonds, roasted peanuts, cheese crackers, and corn chips.

Drizzle the olive oil evenly over the mix and toss to coat all the ingredients.

Sprinkle the ranch seasoning mix over the snack mix and stir well to distribute the seasoning.

Spread the seasoned mix onto a large, parchment-lined baking sheet in an even layer.

Bake for 10 minutes, stirring halfway through to ensure even crisping.

Remove from the oven and allow to cool completely before serving or storing in an airtight container.
