How to Make Oven Roasted Potatoes and Onions
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C).
Line a large baking sheet with parchment paper or lightly grease it with cooking spray.
Step 2: Prepare the Vegetables
Wash and scrub the potatoes thoroughly.
Leave the skins on for extra texture and flavor, or peel them if preferred.
Cut the potatoes into evenly sized cubes to ensure even cooking.
Slice the onions into thin strips.
Step 3: Season Everything
In a large bowl, combine:
- Potatoes
- Onions
- Olive oil
- Melted butter
- Garlic
- Garlic powder
- Onion powder
- Smoked paprika
- Thyme
- Rosemary
- Oregano
- Salt
- Black pepper
Toss until every piece is evenly coated with the seasoning mixture.
Step 4: Arrange on the Baking Sheet
Spread the potatoes and onions into a single layer on the prepared baking sheet.
Avoid overcrowding the pan, as this helps the potatoes roast instead of steam.
Step 5: Roast
Bake for 25 minutes.
Remove the pan and stir the potatoes to ensure even browning.
Return to the oven and roast for another 15–20 minutes, or until the potatoes are crispy and golden brown and the onions are deeply caramelized.
For extra crispiness, switch the oven to broil for the final 2–3 minutes, watching carefully to prevent burning.
Step 6: Serve
Remove from the oven and garnish with fresh parsley, thyme, and a sprinkle of Parmesan cheese if desired.
Serve immediately while hot and crispy.
Tips for Success
- Cut the potatoes into equal-sized pieces for even cooking.
- Use Yukon Gold potatoes for a creamy interior and crispy exterior.
- Don’t overcrowd the baking sheet.
- Flip the potatoes halfway through roasting.
- A hot oven is the key to crispy edges.
- Fresh herbs added after roasting provide the brightest flavor.

Frequently Asked Questions
What are the best potatoes for roasting?
Yukon Gold potatoes offer a buttery texture with crispy edges, while Russet potatoes become extra crispy on the outside and fluffy inside.
Can I prepare this recipe ahead of time?
Yes. You can cut and season the potatoes a few hours in advance. Store them covered in the refrigerator until ready to roast.
Why aren’t my potatoes crispy?
Overcrowding the pan or roasting at too low a temperature can cause steaming instead of browning. Spread the potatoes in a single layer and roast at a high temperature.
Can I use sweet potatoes?
Absolutely! Sweet potatoes make a delicious variation and pair wonderfully with caramelized onions and herbs.
Should I peel the potatoes?
Not necessarily. Leaving the skins on adds texture, nutrients, and extra flavor. Just be sure to scrub them well before cooking.
