Step‑by‑Step Instructions for Crispy Oven Baked Potato Slices
Step 1: Preheat the Oven
Start by preheating your oven to 450°F (232°C). While the oven warms up, line a rimmed baking sheet with parchment paper to ensure the potato slices don’t stick and promote even crisping. This preparation makes your cooking process smooth, setting the stage for delightful Crispy Oven Baked Potato Slices.
Step 2: Slice the Potatoes
Once your oven is preheated, take the medium yellow potatoes and slice them into ¼-inch rounds. Use a mandoline slicer or a sharp knife for uniform slices, which ensures even cooking. Place the sliced potatoes in a large bowl to make mixing with seasonings effortless and enjoyable.
Step 3: Combine the Ingredients
In the same bowl with the potato slices, drizzle in 3 tablespoons of olive oil. Add ¼ teaspoon each of garlic powder, onion powder, black pepper, and ½ teaspoon of dried parsley. Sprinkle in ½ teaspoon of salt, then mix everything thoroughly until the potato slices are evenly coated. This mixture boosts the flavors of your Crispy Oven Baked Potato Slices!
Step 4: Arrange the Potato Slices
Carefully arrange the seasoned potato slices in a single layer on the prepared baking sheet, making sure they don’t overlap. This steps enhances the crispiness by allowing hot air to circulate around each slice, promoting that golden, crunchy finish we all love.
Step 5: Bake for Crispy Perfection
Slide the baking sheet into your preheated oven and bake the potato slices for 20–25 minutes. Halfway through, flip the slices using a spatula to ensure even browning and crispiness. Watch for that lovely golden color on the edges as a sign they are nearing perfection!
Step 6: Add Parmesan Cheese
After the initial baking time, remove the baking sheet from the oven. Sprinkle the remaining 2 tablespoons of Parmesan cheese evenly over the hot potato slices. Pop the baking sheet back into the oven for an additional 3 minutes, allowing the cheese to melt and become bubbly, giving your Crispy Oven Baked Potato Slices a delightful finish.
Step 7: Serve and Enjoy
Once the cheese is perfectly melted, take the baking sheet out and let the delicious potato slices cool slightly. Serve them hot, paired with your favorite dipping sauce for an irresistible side dish that will delight your family at the dinner table!

Expert Tips for Oven Baked Potato Slices
Slice Thickness Matters: Ensure your potato slices are uniform at ¼ inch for even baking. Thicker slices may result in a chewy texture, while thinner ones can burn.

Seasoning Variations: Feel free to experiment with different spices or herbs to customize the flavor of your Oven Baked Potato Slices. Smoked paprika or Italian seasoning can add a delightful twist!
Check for Doneness: Keep an eye on your slices in the final baking stage. The perfect crisp will depend on your oven, so start checking at around 20 minutes.
Dipping Delights: Pair your crispy slices with dips like garlic aioli, ranch dressing, or a spicy salsa to elevate the flavor even more!
