Ingredients Notes

The magic of this dish lies in the perfect balance of simple ingredients. Let’s take a closer look at what makes these oven-fried potatoes so delicious.

Potatoes are the star of the show. I recommend using russet potatoes for the crispiest results, as their high starch content allows for a golden crust. If you prefer a creamier texture, Yukon Golds are another excellent option.

Onions add a subtle sweetness that perfectly complements the crispy potatoes. Yellow onions work best for a classic flavor, but red onions add a mild, slightly tangy note if you want to switch things up.

Olive oil is essential for achieving that crispy texture in the oven. Make sure to coat the potatoes evenly so they roast up beautifully without drying out.

Seasonings bring the dish to life. A mix of salt, black pepper, garlic powder, and smoked paprika creates a perfectly balanced flavor profile. You can also add a pinch of cayenne for a little heat.

You won’t need any special equipment—just a large sheet pan and parchment paper or foil for easy cleanup.

How To Make This Oven-Fried Potatoes & Onions Recipe

Creating this crispy, flavorful dish is easier than you think. Follow these simple steps to get perfect results every time.

Start by preheating your oven to 425°F (220°C). A hot oven is key to achieving crispy potatoes.

While the oven heats, wash and dice the potatoes into bite-sized cubes. Keeping them uniform in size ensures even cooking. If you have time, soak them in cold water for 20 minutes to remove excess starch—this helps with crispiness.

Next, slice the onions thinly so they caramelize beautifully while baking. Toss them together with the potatoes in a large bowl.

Drizzle olive oil over the mixture and sprinkle with salt, pepper, garlic powder, and smoked paprika. Use your hands or a spatula to mix everything well, ensuring each piece is coated in seasoning.

Spread the mixture onto a lined baking sheet in a single layer. Avoid overcrowding—this ensures the potatoes crisp up instead of steaming.

Roast for about 30-35 minutes, flipping halfway through for even browning. You’ll know they’re done when the potatoes are golden and crispy, and the onions are tender and caramelized.

Storage Options

If you have leftovers (though they rarely last long!), here’s how to store and reheat them.

Store any cooled leftovers in an airtight container in the fridge for up to 4 days. The texture won’t be as crispy, but they’ll still be delicious.

For the best results, reheat in a hot oven (400°F) for about 10 minutes to bring back some crispiness. You can also use an air fryer for a quick and even reheat.

Avoid microwaving if possible, as it tends to make the potatoes soft and a bit soggy.

Variations and Substitutions

This recipe is easy to customize, so don’t be afraid to get creative!

For extra herbaceous flavor, add fresh rosemary or thyme before baking. The fragrant herbs pair beautifully with the roasted potatoes.

If you love cheesy potatoes, sprinkle freshly grated Parmesan or cheddar cheese over the potatoes in the last five minutes of baking for a melty, crispy topping.

Want to add protein? Toss in some diced bacon or sausage before roasting. They’ll crisp up alongside the potatoes and add a smoky, savory bite.

To make it spicy, add a pinch of cayenne or red pepper flakes to the seasoning mix. A drizzle of hot sauce after baking also kicks up the heat.

Prefer a healthier version? Use sweet potatoes instead of russets. They roast beautifully and offer a naturally sweet contrast to the savory onions.

No matter how you make them, these Oven-Fried Potatoes & Onions are guaranteed to become a favorite. Whether you stick with the classic version or try a fun variation, they’re always a crispy, satisfying treat!
