Preheat your oven to 400° F. Line a baking sheet with parchment paper or aluminum foil for easy cleanup. Take the frozen hash browns from the packaging and spread them out in a single layer on the prepared baking sheet. Ensure they are not touching or overlapping for even cooking.
Season the top with a pinch of salt, pepper, or your preferred seasonings. This step is entirely optional and can be adjusted to your taste at the end.
Bake the hash browns for 15-20 minutes. After the first 10 minutes, check them and flip them over with a spatula or tongs to ensure they cook evenly. Spray top with olive oil to enhance crispiness.
If you prefer your hash browns crispier, or you want to add shredded cheese to the top, you can leave them in the oven for an additional 5-10 minutes.
