- Spatula
Step-by-Step Instructions
Step 1: Prepare the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a baking dish or line a baking sheet with parchment paper.
A hot oven helps the potato edges become golden and crisp.
Step 2: Wash the Potatoes
Wash the potatoes very well under cold water.
Scrub the skins to remove any dirt.
You can peel the potatoes if you prefer, but leaving the skins on gives more texture and helps the slices hold their shape.
Step 3: Slice the Potatoes
Slice the potatoes into thin rounds, about ¼ inch thick.
Try to keep the slices even so they cook at the same speed.
If some slices are too thick, they may stay firm while the thinner slices become crisp.
A mandoline slicer works well, but a sharp knife is also fine.
Step 4: Make the Garlic Parmesan Mixture
In a large bowl, combine olive oil, melted butter, minced garlic, salt, black pepper, paprika, garlic powder, oregano, dried parsley, and Parmesan cheese.
Stir until everything is well mixed.
The mixture should look rich, glossy, and full of seasoning.
Step 5: Coat the Potato Slices
Add the sliced potatoes to the bowl.
Toss gently until every slice is coated with the garlic Parmesan mixture.
Use your hands or a spoon to separate the slices so the seasoning gets between them.
This step is important because each potato slice needs flavor.
Step 6: Arrange the Potatoes
Arrange the potato slices in a baking dish in a circular pattern or overlapping rows.
You can also spread them flat on a sheet pan for crispier edges.
If you want the beautiful look from the image, arrange the slices slightly overlapping in a round baking dish.
Pour any remaining garlic butter mixture over the top.
Step 7: Bake
Bake uncovered for 35–45 minutes, or until the potatoes are tender and golden.
The edges should be crisp and lightly browned.
If the tops brown too quickly, cover loosely with foil for the last 10 minutes.
If you want extra crispiness, bake for a few more minutes uncovered.
Step 8: Add Extra Parmesan
During the last 5 minutes of baking, sprinkle a little extra Parmesan cheese over the potatoes.
Return to the oven until the cheese melts and turns golden.
This gives the potatoes a delicious savory crust.
Step 9: Garnish
Remove the potatoes from the oven.
Sprinkle with fresh parsley while they are still hot.
You can also add extra black pepper, chili flakes, or a little lemon zest for freshness.
Step 10: Serve Hot
Serve immediately while the potatoes are warm and crisp.
They taste delicious with sour cream, garlic sauce, ranch dressing, ketchup, spicy mayo, or aioli.

- Do not slice the potatoes too thick.
- Coat every slice with seasoning.
- Use both olive oil and butter for flavor.

Best Potatoes to Use
The type of potato you use changes the texture.
| Potato Type | Result |
|---|---|
| Yukon Gold potatoes | Creamy and buttery |
| Russet potatoes | Fluffy and crisp |
| Red potatoes | Firm and rustic |
| Baby potatoes | Tender and pretty |
| White potatoes | Balanced texture |
Yukon Gold potatoes are one of the best choices because they become creamy inside and golden outside.
Russet potatoes are great if you want a crispier finish.
How to Make the Potatoes Extra Crispy
For crispier potatoes, use a sheet pan instead of a deep baking dish.
Spread the slices in a single layer.
Do not overcrowd them.
You can also soak the sliced potatoes in cold water for 20 minutes, then dry them very well before seasoning. This removes extra starch and helps the edges crisp better.
Make sure the potatoes are dry before adding oil and butter.
Wet potatoes will steam instead of roast.
Delicious Variations
Cheesy Garlic Potato Slices
Add mozzarella or cheddar cheese during the last 10 minutes of baking.
This makes the potatoes extra cheesy and comforting.
Spicy Parmesan Potatoes
Add chili flakes, cayenne pepper, or Cajun seasoning.
This version has a warm spicy kick.
Lemon Herb Potatoes
Add lemon zest and fresh thyme after baking.
This gives the potatoes a fresh and bright flavor.
Bacon Parmesan Potatoes
Sprinkle cooked bacon bits over the potatoes before serving.
The bacon adds smoky flavor and crunch.
Ranch Potato Slices
Add ranch seasoning to the oil mixture.
Serve with extra ranch dressing for dipping.
Rosemary Garlic Potatoes
Use fresh rosemary instead of oregano.
This version pairs beautifully with roasted chicken or steak.

Make-Ahead Instructions
You can slice the potatoes a few hours ahead.
Place the slices in cold water to prevent browning.
Before baking, drain them and dry them very well with paper towels.
You can also mix the garlic Parmesan seasoning ahead of time.
For the best texture, bake the potatoes fresh right before serving.
Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days.
The potatoes will soften slightly after chilling, but they still taste delicious when reheated.
Keep them covered so they do not dry out.
Reheating
Oven Method
Place the potatoes on a baking sheet.
Reheat at 375°F (190°C) for 10–15 minutes, or until hot and crisp.
Air Fryer Method
Air fry at 350°F (175°C) for 5–7 minutes.
This is the best way to bring back crispiness.
Microwave Method
Place one portion on a microwave-safe plate.
Heat for 1–2 minutes.
The microwave is quick, but the potatoes will be softer.
Freezing
Freezing is not recommended for this recipe.
Cooked potato slices can become soft and watery after thawing.
For best results, enjoy them fresh or refrigerated for a few days.
Common Mistakes to Avoid
Slicing Potatoes Too Thick
Thick slices take longer to cook and may not become crispy.
Keep slices around ¼ inch thick.
Not Drying the Potatoes
Moisture prevents crispiness.
Dry the potato slices well if you soak them first.
Underseasoning
Potatoes need enough salt, garlic, herbs, and cheese.
Taste your seasoning mixture before adding it to the potatoes.
Overcrowding the Pan
Crowded potatoes steam instead of roast.
Use a large dish or sheet pan if needed.
Not Baking Long Enough
The potatoes should be golden and tender.
If they are still firm, bake a little longer.
