Warm a large skillet over medium heat.

Add 1/8 cup of the bacon grease.

When bacon grease is hot, carefully place potato slices in the bacon fat. If the pan is not big enough to hold all of the potatoes you will need to cook them in two batches.

While the potatoes are pan frying, place another pan over medium heat.

When grease is hot, add onions. Sauté until lightly caramelized, about 5 minutes.

Once potatoes are golden brown on the bottom, flip the individual potato slices and cook until browned on second side.

Remove to a medium bowl and cook remaining slices, if necessary.

Add sautéed onions to bowl with potatoes. Toss gently but well to combine.

Place finished potatoes in a relish dish.

Garnish with chopped parsley.

Serve hot.
