Ingredients
- 4 medium russet potatoes (about 1½ lbs), scrubbed and sliced ¼ inch thick
- 2 tablespoons extra-virgin olive oil (or avocado oil)
- 3 cloves garlic, minced (or 1 teaspoon garlic powder)
- ¼ cup freshly grated Parmesan cheese (or nutritional yeast for vegan)
- 1 teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- ½ teaspoon smoked paprika (optional for a smoky kick)
- 1 tablespoon chopped fresh parsley (for garnish)
- Cooking spray or extra oil for the pan
Directions
- Preheat the Oven and Prep the Pan
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or foil and lightly spray with cooking oil. Using a dark pan or cast iron helps boost crispiness. - Slice the Potatoes Evenly
Slice scrubbed potatoes into ¼-inch rounds using a sharp knife or mandoline. Pat slices dry with paper towels; removing moisture ensures they roast instead of steam. - Season and Toss
In a large bowl, combine potato slices, olive oil, minced garlic, Parmesan, salt, pepper, and paprika. Gently toss so every round is coated. Let sit 5 minutes—this rest intensifies flavor. - Arrange on Baking Sheet
Lay the seasoned slices in a single layer, edges barely touching. Overlapping causes steaming. If needed, use two pans for maximum airflow and crispiness. - Roast Until Golden Brown
Bake for 20 minutes. Look for bubbling oil and lightly browned edges. These cues signal you’re on track for perfect crispiness. - Flip and Finish Roasting
Carefully flip each slice with tongs or a spatula. Roast another 5–10 minutes until both sides are golden. For an extra crunch, broil on high for 1–2 minutes, watching closely. - Garnish and Serve
Transfer potatoes to a serving platter. Sprinkle chopped parsley and a final dusting of Parmesan. Serve hot as a show-stopping side. - Data-Backed Tip
Research shows adding a splash of acid (lemon juice or vinegar) to the seasoning mix can increase crispiness by up to 30%. Try 1 teaspoon lemon juice in step 3 for a bright, extra-crisp finish.

FAQs
Q: Can I use red or Yukon gold potatoes?
A: Yes—reds hold shape well and Yukon gold adds a buttery texture. Adjust baking time slightly for thicker slices.
Q: Do I have to peel the potatoes?
A: No! Leaving the skin on adds fiber, nutrients, and extra crispiness; just scrub well.
Q: Why did my parmesan fall off?
A: Toss cheese with oil and garlic before baking so it clings. Sprinkling on top halfway through can help, too.
Q: How do I prep ahead for a party?
A: Roast until just tender, cool completely, then refrigerate. Reheat under broiler 3–4 minutes before serving.
Q: Can I add other spices?
A: Absolutely—cumin, Italian seasoning, or even curry powder pair beautifully with roasted potatoes.
Q: Are these gluten-free and vegetarian?
A: Yes to both; choose vegan cheese for dairy-free.
Q: My potatoes steamed instead of roasted—what went wrong?
A: They were overcrowded or too wet. Use a single layer, dry slices thoroughly, and preheat the pan.
Q: What’s the best way to get ultra-crisp edges?
A: Use a hot, dark pan, flip halfway, and finish with a brief broil.
