1 (16 ounce) bag mini pretzel twists
1/2 cup vegetable oil
1 (1 ounce) packet ranch dressing seasoning
Place pretzel twists in a large bowl.
Whisk vegetable oil and ranch dressing in a separate bowl until smooth. Pour mixture over the pretzels. Gently stir to coat. Let stand 15 minutes.
Preheat the oven to 275 degrees F (135 degrees C). Gently toss pretzel mixture again; let stand 15 minutes while the oven preheats.
Divide pretzels between two large rimmed baking sheets; spread out in a single layer.
Bake in the preheated oven for 20 minutes. Remove to cool for 15 minutes. Store in an airtight container.
