You can make this recipe with any kind of potatoes. Baby or petite potatoes will need to be halved. Any variety will work for this recipe.

Just cut the potatoes into small uniform sized pieces so that they will cook evenly and crisp on the edges.


How to make Roasted Potatoes and Onions
- Preheat: set your oven to 425 degrees.
- Prep: Cut the potatoes into halves and dice the onion into chunks.
- Mix it up: Add the potatoes, onions, salt, thyme, garlic powder, pepper, and olive oil to a glass casserole baking dish. Use your hands to toss and combine the oil and spices into the potatoes and onions.
- Bake: Roast the potatoes and onions for 50-60 minutes, checking and stirring every 20 minutes, until crispy on the edges.


How do you make crispy potatoes?
Oil and high heat help make potatoes crispy. It’s also important to try to spread the potatoes out into an even layer without much overlapping.
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.
How to store
- Store: store leftover roasted potatoes and onions in an airtight container in the refrigerator for up to 3 days.
- Reheat: reheat the roasted potatoes in the air fryer or oven for the best texture and crispiness.

Notes
My potatoes were very small, so I just halved them. If yours are a bit larger, you may want to quarter them to get smaller pieces.
