Crispy Parmesan Potato Slices: Golden, Cheesy, and Irresistibly Crunchy

Few side dishes are as simple yet satisfying as Crispy Parmesan Potato Slices. Thinly sliced potatoes are coated with savory seasonings, olive oil, and plenty of Parmesan cheese, then roasted until the edges turn beautifully golden and crisp while the centers remain tender and flavorful.

The Parmesan creates a deliciously toasted crust on the bottom of each slice, while garlic, herbs, and black pepper add extra depth. They are perfect alongside grilled chicken, steak, burgers, or roasted vegetables, but they are also delicious enough to serve as a snack with a creamy dipping sauce.

Ingredients

For approximately 4 servings, you will need:

4 medium russet or Yukon Gold potatoes
3 tablespoons olive oil
¾ cup finely grated Parmesan cheese
1 teaspoon garlic powder
1 teaspoon Italian seasoning
½ teaspoon paprika
½ teaspoon salt
¼ teaspoon freshly ground black pepper
1 tablespoon finely chopped fresh parsley, optional
¼ teaspoon red pepper flakes, optional

Choosing the Right Potatoes

Russet potatoes are excellent when you want particularly crisp edges because their lower moisture content helps them brown beautifully.

Yukon Gold potatoes are another great choice. They have a naturally buttery flavor and produce a slightly creamier center while still becoming crisp around the edges.

Whichever variety you choose, try to select potatoes that are relatively similar in size so the slices cook evenly.

How to Make Crispy Parmesan Potato Slices

Step 1: Prepare the Potatoes

Start by preheating your oven to 425°F (220°C).

Wash and scrub the potatoes thoroughly to remove any dirt. You can peel them if you prefer, but leaving the skins on gives the slices additional texture and a rustic appearance.

Pat the potatoes completely dry with a clean kitchen towel.

Slice each potato into rounds approximately ¼ inch (6 mm) thick.

Try to keep the slices as uniform as possible. If some slices are very thin while others are thick, the thinner pieces may become overly brown before the thicker ones are completely tender.

Helpful tip

A sharp knife makes it easier to create consistent slices. If you have a mandoline slicer, it can also help produce evenly sized rounds, but use it carefully.

Step 2: Remove Excess Moisture

After slicing the potatoes, place them in a large bowl and pat them gently with paper towels or a clean kitchen towel.

Removing excess moisture is one of the easiest ways to encourage better browning.

Potatoes contain a significant amount of water, and excess surface moisture can cause them to steam rather than roast. The drier the surface, the easier it is for the edges to become crisp.

For especially crispy results, you can let the sliced potatoes sit uncovered for several minutes after drying.

Step 3: Prepare the Parmesan Seasoning

In a small bowl, combine:

Parmesan cheese
Garlic powder
Italian seasoning
Paprika
Salt
Black pepper
Red pepper flakes, if using

Mix everything thoroughly.

The Parmesan should be finely grated rather than left in large shreds. Smaller particles can adhere more evenly to the potato slices and create a more consistent crust.
