Ingredients for this Oven Fried Potatoes & Onions

• 4 medium russet potatoes, scrubbed and diced (leave the skins on for texture)
• 1 large yellow onion, sliced thin
• 3 tablespoons olive oil (or melted butter for extra flavor)
• 1 teaspoon garlic powder
• 1 teaspoon smoked paprika
• ½ teaspoon dried thyme
• Salt and freshly ground black pepper, to taste
• Optional: chopped parsley or chives for garnish

Step 1: Preheat and Prep

Start by preheating your oven to 425°F (220°C). While it heats, line a large baking sheet with parchment paper or lightly grease it with cooking spray to prevent sticking. This ensures the potatoes get that signature crisp without burning or sticking to the tray.

Step 2: Slice and Dice

Dice your potatoes into bite-sized chunks—about ¾-inch pieces work best for even cooking. Slice the onion thinly into half-moons so it cooks down and caramelizes beautifully in the oven without burning.

Step 3: Season Generously

In a large mixing bowl, combine the diced potatoes and sliced onions. Drizzle with olive oil or melted butter, then add garlic powder, smoked paprika, thyme, salt, and pepper. Toss everything well to coat evenly; every piece should be glistening with flavor.

Step 4: Spread and Roast

Pour the seasoned potato and onion mixture onto the prepared baking sheet. Spread them out into a single layer—don’t overcrowd the pan. This is key to getting crispy edges rather than steaming the veggies.

Roast in the oven for 35–40 minutes, flipping halfway through. The potatoes should be golden brown and crispy on the outside, while the onions will turn soft, sweet, and slightly caramelized.

Step 5: Finish and Serve

Once done, remove from the oven and let rest for a couple of minutes. Sprinkle with freshly chopped parsley or chives if you like a pop of color and freshness. Serve immediately while hot and crisp—these are best enjoyed straight from the tray!

Storage Instructions

To store leftover Oven Fried Potatoes & Onions, allow them to cool completely before transferring to an airtight container. Keep them in the refrigerator for up to 4 days.

To reheat, the best method is using the oven or air fryer to restore their crispiness. Preheat the oven to 400°F (200°C) and bake for 8–10 minutes, or toss them in the air fryer for 5–7 minutes. Microwaving is quicker but will result in softer, less crispy potatoes.

You can also freeze them, though texture may suffer slightly. Place cooled potatoes in a single layer on a baking sheet to freeze individually first, then transfer to a freezer-safe bag. Reheat directly from frozen in the oven for best results.

Frequently Asked Questions

What type of potatoes work best for oven frying?

Russet potatoes are ideal for this recipe because they get fluffy inside and crisp outside. Yukon Golds can also work for a creamier texture.

Can I use red onions instead of yellow?

Absolutely! Red onions bring a slightly sweeter and sharper flavor. They caramelize nicely and add beautiful color, too.

Do I need to peel the potatoes?

Not at all. Leaving the skins on adds texture, flavor, and nutrients. Just be sure to scrub them clean beforehand.

Can I add other vegetables?

Yes! Bell peppers, mushrooms, or zucchini make great additions. Just keep pieces uniform in size to ensure even roasting.

How do I make them extra crispy?

Spread the mixture in a single layer, don’t overcrowd the pan, and use a hot oven (425°F or higher). A metal baking sheet also helps with crisping.

Is this dish gluten-free?

Yes, it’s naturally gluten-free as long as all your spices and seasonings are certified gluten-free.

Can I prepare this in advance?

You can dice the potatoes and onions and store them in cold water up to a day ahead. Drain and pat dry before roasting to prevent sogginess.

What can I serve with Oven Fried Potatoes & Onions?

They pair beautifully with breakfast eggs, roasted meats, or even as a topping for a veggie bowl. They’re versatile enough for any meal of the day!
