Line a baking sheet with aluminum foil and arrange the bacon in a single layer on the foil. Bake for 12 minutes or until crispy.
Transfer the cooked bacon to a paper towel lined plate and allow to cool.
Add the potatoes to the baking sheet and toss in the bacon fat to coat. Arrange the potatoes in a single layer and sprinkle with the parmesan cheese.
Return the baking sheet to the oven and roast for 10-15 minutes. Stir the potatoes and roast for an additional 15-20 minutes until golden brown and crispy.
Season the potatoes with salt and pepper. Crumble the reserved bacon and toss with the potatoes.
Serve immediately.
Notes
Potatoes can be served hot or at room temperature.
