Ingredients Notes

The beauty of this recipe lies in its simple ingredients, each playing a key role in flavor and texture.

Russet potatoes are my go-to for this dish. They crisp up beautifully in the oven, thanks to their high starch content. If you prefer a creamier texture, Yukon Golds are a great alternative.

Yellow onions add a touch of sweetness as they roast. You can also use red onions for a slightly bolder flavor.

Olive oil helps the potatoes crisp up without making them greasy. Avocado oil is another great option, especially if you prefer a higher smoke point.

Seasonings like salt, pepper, garlic powder, and paprika bring out the best in the potatoes. Feel free to add fresh herbs like rosemary or thyme for an extra layer of flavor.

A large baking sheet is essential to ensure the potatoes crisp up properly. Overcrowding the pan can lead to steaming instead of roasting, so use two sheets if needed.

How To Make Oven-Fried Potatoes & Onions

Making these crispy, flavorful potatoes couldn't be easier. Let’s break it down step by step.

Start by preheating your oven to 425°F. While it heats, scrub and cut your potatoes into thin slices or small wedges—about ¼-inch thick for the best texture.

Next, slice your onions thinly. You want them to be thin enough to caramelize as they roast but not so thin that they burn before the potatoes are done.

In a large mixing bowl, toss the sliced potatoes and onions with olive oil and seasonings. Make sure everything is evenly coated so each bite is packed with flavor.

Spread the mixture out in a single layer on a baking sheet. If the potatoes overlap too much, they won’t crisp up as well, so give them some space!

Bake for 30-40 minutes, flipping halfway through. You’ll know they’re ready when the potatoes are golden brown and crispy on the edges, and the onions are soft and caramelized.

Storage Options

If you have leftovers (which is rare!), store them in an airtight container in the fridge for up to 4 days.

To reheat, pop them back in a 400°F oven for 10-15 minutes to regain their crispiness. You can also use an air fryer for a quick reheat.

Freezing isn’t recommended, as the texture of the potatoes can become grainy when thawed.

Variations and Substitutions

This recipe is easily adaptable to suit your preferences.

For a spicy kick, add a pinch of cayenne pepper or red pepper flakes.

If you love cheesy potatoes, sprinkle some grated Parmesan or sharp cheddar over the potatoes in the last 5 minutes of baking.

For a garlic lover’s twist, roast a few whole cloves of garlic alongside the potatoes and onions, then mash them up and mix in before serving.

Want extra crispiness? Add a tablespoon of cornstarch to the potatoes before tossing them with oil—it helps create an extra crunchy coating.

No matter how you customize them, these oven-fried potatoes and onions are guaranteed to be a hit. Enjoy!
