Preheat oven to 250 degrees F.
Divide the pretzels into two large roasting pans (disposable aluminum pans are great for this). Stir the oil, ranch mix, dill, and garlic powder in a small bowl until well combined. Pour evenly over the pretzels, stirring to coat. Bake for 1 hour, stirring halfway. Serve and store at room temperature.
No Bake Method: Instead of baking the oiled pretzels, leave them to soak for several hours, while occasionally stirring.
Recipe Note: This recipe makes a huge amount, but can easily be halved.
