3. Step-by-Step Cooking Instructions & Crisping Secrets
The key to achieving that perfect crispy texture is to cook the potatoes in a hot oven (425°F/220°C) for 15 minutes, then broiling for an additional 2-3 minutes to get that golden-brown color.
To ensure even cooking, I recommend using an instant-read thermometer to check the internal temperature.
And don’t forget to sprinkle shredded cheddar cheese over the potatoes during the last minute of cooking!

Step-by-Step Culinary Timeline
1. Preheat your oven to 425°F (220°C) or air fryer to 400°F (200°C).
2. Scrub and slice each potato into 1/8-inch thick layers, leaving a 1/4-inch gap between each slice.
3. Drizzle olive oil over the potatoes, then sprinkle with salt, black pepper, garlic powder, and dried rosemary.
4. Arrange the potatoes in a single layer on a baking sheet or in the air fryer basket.
5. Bake or air-fry for 15 minutes, or until the potatoes are golden brown and crispy.
6. Sprinkle shredded cheddar cheese over the potatoes and return to the oven or air fryer for an additional 2-3 minutes, or until the cheese is melted and bubbly.
Meal-Prep Storage & Crispy Air-Fryer Reheating Guide
• Cool Before Sealing: Let cooked portions cool for 10 minutes before sealing in glass containers so steam never softens the crust (keeps 4 days in the fridge).
• Sauce on the Side: Store dips, drizzles, and fresh herbs separately until right before serving.
• 3-Minute Crispy Reheat: Reheat in a 380°F (193°C) air fryer or dry cast-iron skillet for 3–4 minutes to restore shatteringly crisp edges.
