Method
- Heat the oven to 425°F and lightly grease an 18x13-inch rimmed baking sheet with 1 tablespoon of the olive oil.
- Toss the potatoes in a large bowl with the remaining 2 tablespoons olive oil and the ranch seasoning mix, then add the Parmesan and toss until evenly coated.
- Arrange the potatoes in a single layer on the baking sheet, cut sides down where possible, and roast for 35 to 45 minutes without turning, until tender and deeply golden and crisp underneath.
- Let the potatoes rest on the baking sheet for 5 minutes before serving.
Notes
For the crispiest undersides, arrange the potatoes cut sides down where possible and leave them undisturbed while roasting. Refrigerate leftovers for 3–4 days; freezing is not recommended because the potatoes can lose their crisp texture. For a dairy-free version, use dairy-free ranch seasoning and Parmesan-style cheese.
