Prepare the Potatoes

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C). This high temperature will help the potatoes crisp up nicely.
2. Slice the Potatoes: Wash and peel your potatoes if you prefer (the skins are optional). Slice them into thin rounds, about 1/4-inch thick. The thinner the slices, the crispier they’ll get, so aim for uniformity to ensure even cooking.
3. Season the Potatoes: Place the sliced potatoes in a large bowl. Drizzle with olive oil, then sprinkle on garlic powder, onion powder, paprika, salt, and pepper. Toss everything together, making sure all the slices are coated evenly with the seasoning.
4. Prepare the Baking Sheet: Line a baking sheet with parchment paper or lightly grease it with cooking spray. This will prevent the potatoes from sticking and ensure they bake evenly.

Cook the Potatoes

1. Arrange the Potatoes: Spread the seasoned potato slices in a single layer on the baking sheet. Be sure they’re not overlapping too much to allow for even crisping.
2. Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes, flipping the potatoes halfway through for even cooking. Keep an eye on them as they bake—once they’re golden and crispy, they’re ready to come out!
3. Check for Crispiness: Depending on how thin you’ve sliced your potatoes, you may need to bake them a bit longer. If you want them extra crispy, feel free to add a few extra minutes of baking time.

Serve and Garnish

1. Garnish: Once your Sliced Potatoes are done baking, remove them from the oven and let them cool for a few minutes. Garnish with freshly chopped parsley if desired, and serve immediately!
