This Parmesan potato recipe was a childhood favorite. My mom didn’t often make frozen french fries or tots (which I rely on!), so this was the closest we got to crispy, crunchy potatoes. As a kid I dipped these in ketchup, but now I much prefer a side of sour cream.
I’ve also adjusted the recipe to have a bit more spice and use cornstarch instead of the all purpose flour my mom used. I find the potatoes come out a bit crispier and it keeps this appealing side dish gluten free.
This recipe has always been free of excess oil, skipping both olive oil and melted butter in favor of cooking spray. You can use an olive oil mister in place of the cooking spray, which is what I do when making these.
Ingredients
- Russet potatoes
- Parmesan cheese
- Cornstarch
- Garlic powder
- Onion powder
- Paprika
- Salt
- Black pepper
- Sour cream (optional)
How to Make Parmesan Potato Rounds
Heat oven to 400.
Line a baking sheet with parchment paper.
In a shallow bowl, combine cheese, cornstarch, garlic powder, onion powder, paprika, salt, pepper. Set aside.
Peel the potatoes, if desired.
Slice potatoes about ¼ inch thick.
Press each side of a potato slice into the cheese mixture.
Place the slice of potato onto the prepared baking sheet, leaving a little bit of space between them.
Repeat with remaining slices, placing in a single layer on the large sheet pan.
Spray potatoes with cooking spray.
Place in the oven and cook for 15 minutes.
Flip the potatoes over, spray the second side with cooking spray, and continue to cook for another 20 mins.
Remove from the oven.
Serve with a side of sour cream.

Recipe Tips
- Use a mandolin slicer to get an even cut on your potatoes. I use the thickest slice setting available on mine.
- Do NOT rinse your potato slices or pat them dry with a paper towel. In order to make this recipe work without adding butter or oil, it's absolutely necessary to keep the starch on the potato.
FAQs and Substitutions
A mandolin slicer is the easiest way to get an even cut on your potatoes. I use the thickest slice setting available on mine.
Use fresh Parmesan cheese or the cheese in the can - it’s up to you! I photographed these with fresh Parmesan, but have eaten them many times with grated cheese from the green can and both are delicious! Reggiano cheese can be substituted for the Parmesan, if you prefer.
Peeling the potatoes is 100% optional. If you enjoy potato skin and don’t want to spend time peeling potatoes, give them a good scrub and skip the peeling!
Russet potatoes have a high starch content and will give you a crispy outside and tender inside on these Parmesan potato rounds. All that starch is also what makes the cheese mixture cling to the potato slices. Substituting a different type of potato may lead to issues with the cheese mixture sticking to the potatoes.
