3 tablespoons olive oil
¾ cup freshly grated Parmesan cheese

Why You’ll Love These Potato Rounds
This recipe turns basic potatoes into something that feels much more special. The Parmesan creates a deeply golden crust while the garlic, butter, paprika, and herbs add plenty of savory flavor.
Another advantage is that there is no deep frying. High-temperature roasting gives the potatoes crisp edges while keeping the inside tender.
They are also easy to customize. You can make them spicy, extra cheesy, or serve them with several different sauces.
Choosing the Best Potatoes
Russet potatoes are an excellent choice because their high starch content produces a fluffy interior while allowing the outside to become crisp.
Yukon Gold potatoes can also be used. They have a naturally buttery flavor and creamier center, although they may not become quite as crisp.
Try to select potatoes of approximately the same width so your rounds cook evenly.
Prepare the Potatoes
Preheat the oven to 425°F (220°C).
Wash and scrub the potatoes thoroughly because the skin can remain on.
Dry them very well.
Slice each potato into approximately ½-inch-thick rounds. Keeping the slices similar in thickness is important because thin slices may burn before thicker ones become tender.
Place the rounds in a large bowl.
The Trick for Crispier Potatoes
For an especially crisp exterior, soak the sliced potatoes in cold water for about 20–30 minutes.
This helps remove some surface starch.
Drain and dry the slices extremely well with clean kitchen towels or paper towels.
Moisture left on the potatoes can create steam in the oven and prevent proper browning.
If you’re short on time, you can skip the soaking step, but don’t skip drying them.
Make the Garlic Parmesan Coating
In a bowl, combine the Parmesan cheese, minced garlic, garlic powder, smoked paprika, Italian seasoning, onion powder, salt, and black pepper.
Drizzle the potato rounds with olive oil and toss until every piece has a light coating.
Add the Parmesan mixture.
Toss gently until both sides of the potato slices are generously coated.
Arrange for Maximum Crispiness
Line a large baking sheet with parchment paper or lightly grease it.
Arrange the potato rounds in one single layer.
Don’t stack or overlap them.
Leaving a little space between each slice allows hot air to circulate and gives you better browning.
Sprinkle any remaining Parmesan mixture over the tops.
Bake Until Golden
Bake for approximately 20 minutes.
Carefully flip each potato round.
Brush or drizzle lightly with melted butter.
Return to the oven for another 10–15 minutes, or until both sides are deeply golden and the centers are fork-tender.
For extra browning like the potatoes in the photo, broil them for approximately 1–2 minutes at the end. Watch closely because Parmesan can brown very quickly.
Serve
Remove the potatoes from the oven and let them rest for about 3–5 minutes.
This short resting period helps the cheesy coating firm up and become even crispier.
Sprinkle with fresh parsley and a little extra Parmesan before serving.
They are especially delicious while still warm.
Best Dipping Sauces
These potato rounds work with many sauces. Try garlic aioli, ranch dressing, spicy mayo, sour cream and chives, honey mustard, or marinara.
For a simple garlic dip, combine mayonnaise with a little lemon juice, minced garlic, black pepper, and Parmesan.
Extra-Crispy Parmesan Version
If you love the crunchy cheese crust, sprinkle small piles of grated Parmesan directly onto the baking sheet and place one potato round on each pile.
As the potatoes roast, the cheese underneath melts and caramelizes into a crisp Parmesan crust.
Flip carefully so the crust remains attached.
Spicy Version
Add ¼–½ teaspoon cayenne pepper or crushed red pepper flakes to the Parmesan mixture.
You can also serve the finished potatoes with spicy mayonnaise or hot honey for a sweet-and-spicy contrast.
Garlic Butter Version
For an even richer flavor, combine:
3 tablespoons melted butter
2 minced garlic cloves
1 tablespoon parsley
2 tablespoons Parmesan
Brush this mixture lightly over the potatoes during the final few minutes of baking.
What to Serve With Them
These crispy potatoes make an excellent side for grilled chicken, roasted chicken, steak, meatloaf, burgers, baked fish, or sandwiches.
For parties, serve them on a large platter with two or three dipping sauces and let everyone grab their own.
Storage
Allow leftovers to cool completely before transferring them to an airtight container.
Store in the refrigerator for up to 3–4 days.
The potatoes will soften slightly during refrigeration, so reheating them correctly is important.
How to Reheat
For the best texture, reheat the potato rounds in a 400°F (200°C) oven for about 8–10 minutes.
An air fryer also works very well. Heat at approximately 375°F (190°C) for 4–6 minutes.
The microwave is convenient but will make the Parmesan coating much softer.
Common Mistakes
Cutting uneven slices: Similar thickness means more even cooking.
Using wet potatoes: Excess moisture creates steam instead of crispness.
Overcrowding the baking sheet: Give every potato round some space.
Using too little oil: A light coating helps the seasoning adhere and promotes browning.
Adding excessive salt: Parmesan is already salty, so season carefully.
Walking away while broiling: The cheese can go from golden to burned very quickly.
Frequently Asked Questions
Do I need to peel the potatoes?
No. Keeping the skin gives the rounds extra texture and helps them hold their shape. Just scrub the potatoes thoroughly.
Can I use pre-grated Parmesan?
Yes, but freshly grated Parmesan generally melts and browns better.
Can these be made in an air fryer?
Yes. Arrange them in one layer and cook at approximately 390°F (200°C) for 15–20 minutes, flipping halfway through. Cooking time depends on thickness and the air fryer.
Why aren’t my potatoes crispy?
The most common reasons are excess moisture, overcrowding, insufficient oven temperature, or slices that are too thick.
Can I prepare them ahead?
You can slice the potatoes several hours ahead and keep them submerged in cold water in the refrigerator. Before seasoning and baking, drain and dry them extremely well.
Final Thoughts
Crispy Garlic Parmesan Potato Rounds are proof that a few inexpensive ingredients can create an incredibly satisfying side dish. The combination of a crunchy Parmesan-garlic crust and a fluffy potato center makes them hard to stop eating.
Serve them straight from the oven with your favorite dipping sauce, and don’t forget those crispy Parmesan pieces left on the baking sheet—they may be the best part. 🥔🧄🧀
