Preheat oven to 425º F.
Rinse the potatoes under cool water and pat dry. Slice them in half, or into bite-sized chunks, then place them into a large mixing bowl.
Drizzle the potatoes with olive oil, then add the grated garlic. Using your hands, mix and massage the oil and garlic onto the potatoes to ensure even coverage.
Sprinkle the Everything Bagel Seasoning over the potatoes, followed by a pinch of salt and a few cracks of black pepper; toss the potatoes to coat them.
Transfer the potatoes to a cast iron skillet or a baking sheet. Bake in the oven for 25-30 minutes or until the potatoes turn golden in color and the edges crisp up. Halfway through, flip the potatoes with a spatula to ensure an even crisp, and sprinkle the shredded cheese on top.
