How to make Roasted Potatoes in Oven

4. Bake: Roast the potatoes and onions for 50-60 minutes, stirring every 20 minutes, until crispy on the edges.

How do you make crispy potatoes?

To make your potatoes crispy, you need oil and around 45 minutes to an hour of roasting time. Be sure to use a pan large enough for the potatoes to be spread out in an even layer. This will ensure that each potato has the chance to get those crispy edges!

Bake the potatoes and onions at 425 degrees for around an hour, checking to flip and stir every 15 minutes or so. Each time you flip the potatoes, use a spatula to make sure any edges are scraped from the pan. This will help get the potatoes evenly cooked and crispy on more sides.
