Wash, pat dry, and quarter potatoes (for larger ones you may need to chop into slightly smaller pieces, about 1 inch pieces).
Place chopped potatoes in a large resealable bag. Drizzle olive oil into the bag, seal, and toss to coat the potatoes.
Open the bag, sprinkle in half of the ranch seasoning, seal, toss to coat, then repeat with remaining seasoning.
Thread potatoes on skewers. Grill over low heat for 10-20 minutes (depending on your grill and the size of your potatoes) turning throughout to ensure even cooking. When fork-tender, remove from grill and serve warm with cold ranch dressing if desired. Enjoy!
Take it to the next level by serving with a delicious dipping sauce! (My family loves ranch or my personal favorite, equal parts mayo and bbq sauce!)
