Ingredients Notes

The magic of this dish comes from a few simple ingredients that work together perfectly.

Potatoes – I recommend using Yukon Gold or Russet potatoes for the best texture. Yukon Golds have a naturally buttery flavor and hold their shape well, while Russets crisp up beautifully on the edges.

Onions – Sweet yellow onions work best here, as they develop a rich caramelized flavor when roasted. However, red onions or white onions also work if that’s what you have on hand.

Olive oil – This is key for achieving crispy edges. A good quality extra virgin olive oil helps the potatoes brown beautifully and adds great flavor. You can also use avocado oil for a higher smoke point.

Seasonings – A simple mix of salt, black pepper, garlic powder, and paprika enhances the natural flavors of the potatoes and onions. Paprika adds a touch of smokiness, while garlic powder gives it that extra depth of flavor.

Optional add-ins – If you want to take things up a notch, consider adding fresh rosemary, thyme, or Parmesan cheese for extra flavor.

How To Make Oven Fried Potatoes & Onions

Making this dish is easier than you think and requires very little hands-on time.

Start by preheating your oven to 425°F. A high temperature is key for getting those crispy, golden-brown edges on the potatoes. While the oven heats, line a large baking sheet with parchment paper or lightly grease it with oil.

Next, wash and slice your potatoes into thin wedges or rounds—about ¼-inch thick. Keeping them uniform ensures even cooking. Then, thinly slice the onions into rings or half-moons.

In a large mixing bowl, toss the potatoes and onions with olive oil, salt, black pepper, garlic powder, and paprika. Make sure everything is evenly coated so every bite is packed with flavor.

Spread the mixture out on your prepared baking sheet in a single layer. Avoid overcrowding—this allows the potatoes to crisp up instead of steaming.

Roast in the oven for 25-30 minutes, flipping the potatoes halfway through for even browning. You’ll know they’re done when they’re crispy and golden on the outside, with soft, tender insides.

For extra crispiness, you can broil them for 2-3 minutes at the end—just keep an eye on them to prevent burning!

Storage Options

If you have leftovers (which is rare because they’re so good!), here’s how to store them:

• Refrigerator: Store cooled potatoes and onions in an airtight container for up to 4 days.
• Freezer: While freezing isn’t ideal for roasted potatoes, you can store them in a freezer-safe bag for up to 2 months. Reheat in the oven for the best texture.
• Reheating: Warm them up in a 375°F oven for 10-15 minutes to crisp them back up, or heat in a skillet with a little oil over medium heat.

Variations and Substitutions

This recipe is super customizable, so feel free to mix things up!

• Add cheese – Sprinkle shredded Parmesan or cheddar over the potatoes in the last 5 minutes of baking for a cheesy twist.
• Make it spicy – Add a pinch of cayenne pepper or red pepper flakes for a little heat.
• Herb-infused – Toss in some fresh rosemary, thyme, or parsley for an herby kick.
• Switch up the potatoes – Try using red potatoes or baby potatoes for a different texture.
• Add bacon – Cook and crumble some crispy bacon over the top before serving for an extra savory touch.
