Preheat the oven to 425°F (or cook fries in the air fryer per directions in the notes).
Add the fries to a rimmed baking sheet and cook for 25-30 minutes or until extra crisp, stirring after 15 minutes.
Once the fries are crisp, remove them from the oven and turn the broiler on to 500°F.
Top the fries with cheddar and bacon and place back into the oven for 1-3 minutes or until the cheese is melted.
Top with green onions. If using, drizzle with brown gravy and top with sour cream. Serve immediately.
