Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
4 medium yellow potatoes, scrubbed and sliced into thin rounds
3 tablespoons olive oil
1/4 teaspoon garlic powder
1/4 teaspoon onion powder
1/4 teaspoon paprika
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 cup grated Parmesan cheese
1 tablespoon chopped fresh parsley (optional for garnish)
Directions
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or lightly grease it to prevent sticking.
Wash the potatoes thoroughly and scrub the skins clean. Do not peel them. Slice the potatoes into thin rounds about 1/4 inch thick so they cook evenly.
Place the potato slices in a large mixing bowl. Add the olive oil and toss until all slices are well coated.
Sprinkle the garlic powder, onion powder, paprika, salt, and black pepper over the potatoes. Toss again to distribute the seasonings evenly.
Arrange the potato slices in a single layer on the prepared baking sheet. Make sure the slices are not overlapping to allow them to crisp properly.
Sprinkle the grated Parmesan cheese evenly over the top of the slices.
Bake in the preheated oven for about 25 to 30 minutes, flipping the slices halfway through the cooking time.
Continue baking until the potatoes are golden brown and crispy around the edges.
Remove from the oven and sprinkle with chopped parsley if desired. Serve warm with ketchup, yogurt dip, or your favorite sauce.

Storage/Reheating
Store leftover potato slices in an airtight container in the refrigerator for up to 3 days.
To reheat, place the slices on a baking sheet and warm them in the oven at 375°F (190°C) for about 8 to 10 minutes until they become crispy again.
You can also reheat them in an air fryer for 4 to 5 minutes for the best crisp texture.
Avoid reheating in the microwave if possible, as it can make the potatoes soft instead of crispy.
FAQs
Can I use a different type of potato?
Yes, you can use russet potatoes, red potatoes, or Yukon gold potatoes. Each type will give a slightly different texture but will still taste great.
Do I need to peel the potatoes?
No, the skins help add texture and flavor. Just make sure the potatoes are thoroughly washed and scrubbed.
How thin should the potato slices be?
About 1/4 inch thick works best. Thin slices cook evenly and become crispy without burning.
Why are my potato slices not crispy?
This usually happens when the slices overlap on the baking sheet or if there is too much moisture. Make sure the slices are arranged in a single layer.
Can I make this recipe without Parmesan cheese?
Yes, the recipe will still be delicious without cheese. You can replace it with nutritional yeast or simply leave it out.
Can I prepare the potatoes ahead of time?
You can slice the potatoes ahead and store them in cold water in the refrigerator for a few hours to prevent browning.
What sauces go well with these potato slices?
They pair well with ketchup, garlic yogurt sauce, ranch-style dips, or a simple tomato sauce.
Can I cook these in an air fryer?
Yes. Cook them at 380°F (193°C) for about 12 to 15 minutes, shaking halfway through for even cooking.
How do I make them extra crispy?
Make sure the slices are dry before adding oil and avoid overcrowding the baking sheet.
Can I freeze oven baked potato slices?
Freezing is not recommended because the texture can become soft when reheated. They taste best when freshly baked.
