Add the mini pretzels to a large mixing bowl, ensuring enough space for easy mixing.
In a small bowl, combine vegetable oil, ranch seasoning mix, garlic powder, onion powder, smoked paprika, dried dill, and cayenne pepper. Stir thoroughly until the mixture is smooth and evenly blended.
Gradually pour the seasoning mixture over the pretzels, tossing gently as you pour to ensure even distribution. Continue mixing until all pretzels are fully coated with the seasoned oil.
Allow the coated pretzels to rest for 15 to 20 minutes. Stir every 5 minutes to help the seasoning absorb evenly into the pretzels.
For a crispier texture, preheat the oven to 250°F (120°C). Spread the pretzels in a single layer on a parchment-lined baking tray. Bake for 20 minutes, stirring halfway through to ensure even drying and crisping.
Remove the pretzels from the oven and allow them to cool completely on the tray. This step is important as it helps the pretzels firm up and develop a crunchy texture.
Once fully cooled, transfer to a serving bowl or store in an airtight container for later use.
