Step 6: Arrange on a Baking Tray
Preheat the oven to 425°F, or 220°C.
Line a baking sheet with parchment paper or lightly grease it with oil. Arrange the potato rounds in a single layer. Do not stack them.
Leave a little space between each slice. If the potatoes are too close together, they will steam instead of crisp.
Sprinkle the remaining parmesan mixture over the top of the potatoes.
Step 7: Bake Until Golden
Place the tray in the preheated oven and bake for 25 to 30 minutes.
After about 15 minutes, carefully flip each potato slice. This helps both sides become golden and crispy.
Continue baking until the potatoes are tender inside and the cheese is browned on the outside. The edges should look crisp, and the tops should have a golden parmesan crust.
If you want a darker, crispier top, turn on the broiler for 1 to 2 minutes at the end. Watch carefully because cheese can burn quickly.
Step 8: Let Them Rest Before Serving
Once the potatoes are done, remove the tray from the oven and let them rest for 3 to 5 minutes.
This short resting time helps the parmesan crust firm up. If you move them immediately, the cheese may still be soft.
After resting, transfer the potato rounds to a serving plate.
Step 9: Garnish and Serve
Sprinkle fresh parsley over the hot potato rounds for color and freshness.
Serve them warm with your favorite dipping sauce. Ranch, garlic aioli, sour cream, or spicy mayo work especially well.
These crispy parmesan potato rounds can be served with grilled chicken, steak, burgers, roasted vegetables, or even as a snack on their own.
Air Fryer Method
You can also make this recipe in an air fryer.
Preheat the air fryer to 400°F, or 200°C. Arrange the coated potato slices in a single layer in the basket. Cook for 15 to 20 minutes, flipping halfway through.
The air fryer makes the potatoes extra crispy, but you may need to cook them in batches depending on the size of your air fryer.
Pan Method
For a quicker version, you can cook the potato rounds in a skillet.
Boil the potato slices for 5 minutes first to soften them slightly. Drain and dry them well. Then coat them with the parmesan mixture and cook in a lightly oiled skillet over medium heat until both sides are golden and crispy.
This method gives a nice crust, but baking is easier when making a large batch.
Helpful Tips for Best Results
Do not skip drying the potatoes. Moisture is the enemy of crispiness.
Use fresh parmesan if possible. It melts and browns better than some pre-packaged cheeses.
Do not overcrowd the tray. Give the potatoes enough space to roast properly.
Slice the potatoes evenly. Uneven slices may cook at different speeds.
Use parchment paper for easier cleanup, but make sure the potatoes still have enough oil and butter to brown well.
For extra flavor, add a pinch of cayenne pepper, Cajun seasoning, rosemary, or dried thyme.
Flavor Variations
For a spicy version, add cayenne pepper, chili flakes, or Cajun seasoning.
For a herb-style version, use rosemary, thyme, parsley, and oregano.
For a loaded potato version, top the baked rounds with sour cream, crispy bacon bits, green onions, and extra cheese.
For a garlic butter version, brush the potatoes with melted garlic butter after baking.
For a smoky version, use smoked paprika and a small pinch of chipotle powder.
Storage and Reheating
Store leftover potato rounds in an airtight container in the refrigerator for up to 3 days.
To reheat, place them in the oven at 375°F, or 190°C, for 8 to 10 minutes. You can also reheat them in an air fryer for 4 to 6 minutes.
Avoid microwaving if possible because the potatoes will become soft and lose their crispy texture.
Final Thoughts
Crispy Parmesan Potato Rounds are easy, affordable, and full of flavor. They are crunchy on the outside, soft inside, and coated with a rich garlic parmesan crust that makes every bite satisfying.
This recipe is perfect when you want a side dish that feels special without requiring much effort. Whether served with dinner, offered as a party appetizer, or enjoyed as a snack, these golden potato rounds are a simple comfort-food favorite.
