Preheat your campfire grill or set up a campfire with a grate over the flames.
Place the frozen hash brown patties directly onto the grill or grate.
Cook the hash browns for 5-7 minutes on each side, or until they are golden and crispy.
While the hash browns are cooking, melt the butter in a small saucepan or skillet over the campfire.
Once the hash browns are cooked on both sides, brush them with the melted butter.
Season the hash browns with salt and pepper to taste.
Continue cooking for an additional 2-3 minutes, or until the hash browns are fully cooked and crispy on the outside.
Remove the hash browns from the grill and serve hot.
