Preheat oven to 400 degrees F. Line a large rimmed baking sheet with parchment paper.
Place potato slices in a single layer on the prepared baking sheet. Drizzle olive oil over the tops and brush to coat. Place in a single layer on the prepared baking sheet. Sprinkle with salt. Bake in the preheated oven for 30 minutes.
Remove from oven and top with cheese and bacon. Bake for another 5 minutes, or until cheese has melted. Serve warm, finger-food style.
Notes
Swap out red potatoes for sweet potatoes or Yukon golds.
These are great cold the next day too, so refrigerate any leftovers!
Swap out toppings with other toppings of your choice (broccoli, cauliflower, sausage, chicken, tomatoes).
