Preheat oven to 350°F. Line a baking sheet with parchment paper and lightly grease.
Roll out crescent dough into a rectangle and press any seams together if needed.
Spread a thin layer of ranch dressing over the dough.
Layer on the mozzarella, rotisserie chicken, and bacon.
Roll tightly from the long side into a log, then slice into 1-inch pinwheels.
Place slices on prepared baking sheet. Optional: Chill in the fridge for 45–60 minutes to help them hold their shape.
Bake for 18–22 minutes or until golden.
While baking, stir garlic into melted butter.
Once baked, brush pinwheels with garlic butter and drizzle with extra ranch. Garnish with parsley if desired.
