In a medium-sized mixing bowl, add 2 tablespoons of light olive oil, 1/2 teaspoon garlic powder, 1/4 teaspoon onion powder, 1/2 teaspoon salt, and a dash of black pepper. Add the frozen hash browns and stir with a spatula to evenly coat.
Air Fryer Method: Do not preheat the air fryer. Wrap the air fryer tray with parchment paper and press down into the air fryer basket. Dump in the seasoned hash browns. Cook at 385°F for 15-20 minutes, stirring every 5 minutes, until they are golden brown.
Skillet Method: Bring a skillet to medium/high heat and add the seasoned hash browns. Cook until the hash browns are crispy and golden brown, flipping occasionally, about 10-12 minutes. Set aside.
Oven Method: Line or lightly grease a baking sheet with parchment paper. Spread the seasoned hash browns in an even layer. Bake the hash browns for 20-25 minutes, flipping halfway through, then every 5 minutes until golden brown and crispy. If you prefer extra crispiness, leave them in for a few more minutes.
