Place the pretzels in a large resealable ziplock bag. Mix together the seasonings with the oil and butter and pour over the pretzels. Shake the bag to coat all the pretzels. 

Let the pretzels sit for 15 minutes and then shake the bag and flip it over to the other side. Let it sit another 15 minutes. 

Preheat the oven to 250 degrees. After 30 minutes of marinating the pretzels, spread the pretzels evenly on a large cookie sheet and bake at 250 degrees for 30-45 minutes, stirring halfway through the baking time. You'll know the pretzels are done when no more oil seems to appear on the pretzels and they look well dried. 

Let cool. Store in an airtight container.
