- 4 large potatoes: Starchy and firm, ideal for baking and slicing thin.

- 1 teaspoon salt: Enhances all the flavors and balances the seasoning.
- 1/2 teaspoon black pepper: Gives a subtle kick without overpowering the dish.

How to Make Crispy Parmesan Baked Potato Slices Recipe
Step 1: Preheat and Prep
Start by heating your oven to 400°F (200°C). Washing your potatoes thoroughly under running water is essential to remove any dirt since we’re keeping the skins on for extra texture and nutrition. Then, dry them with a clean towel — this step ensures the olive oil and seasoning will stick perfectly.
Step 2: Slice Your Potatoes Thinly
Using a sharp knife or a mandoline slicer, slice the potatoes into thin rounds about 1/4 inch thick. Thin slices mean you’ll get that coveted crispy edge while keeping some tenderness inside. Consistent thickness helps them bake evenly.
Step 3: Season and Coat
In a large bowl, whisk together the olive oil, salt, black pepper, garlic powder, and grated parmesan cheese. Then, add the sliced potatoes and gently toss to coat every slice. This mixture is the secret to getting both flavor and crispiness.
Step 4: Arrange and Bake
Lay the potato slices in a single layer on a parchment-lined baking sheet — giving each slice some breathing room helps them crisp up nicely. Sprinkle any leftover seasoning mixture evenly over the top. Bake for 30 to 35 minutes until they turn tender with edges golden and crisp.
Step 5: Garnish and Enjoy
Once out of the oven, sprinkle fresh chopped parsley to add a burst of color and freshness. Let the slices cool slightly so they firm up just right, then dive into your Crispy Parmesan Baked Potato Slices Recipe with delight.
How to Serve Crispy Parmesan Baked Potato Slices Recipe

Garnishes
Adding a sprinkle of fresh parsley not only brightens the dish visually but introduces a fresh, herbaceous note that balances the rich parmesan and garlic. For an extra touch, a little grated lemon zest or a drizzle of a light garlic aioli can elevate this snack into gourmet territory.
Side Dishes
These crispy potato slices pair beautifully with grilled chicken, steak, or roasted veggies. They also make a welcome crispy contrast alongside saucy pasta dishes or a vibrant salad. In fact, they can effortlessly replace regular fries for a fresh twist.
Creative Ways to Present
Try stacking the slices with layers of melted cheese and crispy bacon bits for a loaded potato stack. Alternatively, serve them as a base topped with a dollop of sour cream and chives to turn this into an impressive appetizer. Their golden color and texture make them a visually stunning and crave-worthy addition to any table.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To keep their crispiness, separate layers with parchment paper to avoid sogginess caused by moisture buildup.
Freezing
You can freeze the potato slices before baking by laying them flat on a tray and freezing until solid, then transferring to a freezer-safe bag. When ready to enjoy, bake them directly from frozen, adding a few extra minutes to the bake time for best results.
Reheating
Reheat leftovers in a preheated oven at 375°F for about 10 minutes or until warmed through and crisp again. Avoid microwaving as it tends to make the slices soft and less appealing.
FAQs
Can I use a different type of cheese instead of parmesan?
Absolutely! While parmesan adds a unique nutty crunch, you can experiment with other hard cheeses like pecorino romano or asiago for a similar effect.
Are these potato slices gluten-free?
Yes, the Crispy Parmesan Baked Potato Slices Recipe is naturally gluten-free, making it a great snack for those avoiding gluten.
Can I make this recipe vegan?
To keep it vegan, simply swap the parmesan cheese with a plant-based cheese alternative or nutritional yeast for a cheesy flavor without dairy.
What’s the best potato to use for these slices?
Russet potatoes are ideal due to their high starch content, which helps achieve that crisp texture. However, Yukon Golds also work well and give a slightly creamier bite.
How thin should the potato slices be?
About 1/4 inch thick is perfect. Thinner slices can burn quickly and thicker ones won’t crisp as nicely, so aim for that balance.
Final Thoughts
There’s something truly satisfying about the simplicity and crunch of this Crispy Parmesan Baked Potato Slices Recipe. It’s a dish that feels both comforting and special, perfect for sharing or indulging solo. Give it a try—the golden edges, garlicky cheese crust, and fresh parsley finish will have you coming back for more every time.
