Caramelized Onion Cheesy Pinwheels are bursting with flavor from caramelized onions and sharp white cheddar cheese, wrapped in a flaky puff pastry and baked to a golden perfection!
Preheat a large stainless steel pan (any pan will be fine but stainless steel will give better results) on medium-high heat.
Slice the onions thin. Melt the butter in the pan and quickly add the onions. Cook, stirring often, until onions are golden browned (don't burn). Set aside.
Preheat the oven to 400. Grease a cookie baking sheet.
Spread the onions evenly over the dough and top it off with cheese, evenly. Salt to taste (just a little because cheese and onions already have a good amount of flavor).
Roll up the dough, sealing the edge, and slice it into 1-inch rolls.
Place the pinwheels on the cookie sheet and bake for 15-17 minutes, until nicely golden.
