Why You'll Love This Oven-Fried Potatoes & Onions

Get ready to fall in love with a recipe that's as easy as it is delicious. These oven-fried potatoes & onions are a game-changer for any meal of the day.

First, this dish is incredibly simple to prepare. With just a handful of ingredients and minimal effort, you can achieve restaurant-quality roasted potatoes right at home.

It's also budget-friendly. Potatoes and onions are some of the most affordable staples in any kitchen, making this a cost-effective way to add something special to your meal.

Ingredients Notes

The magic of this dish lies in the perfect combination of simple ingredients, each playing a crucial role in achieving that crispy, caramelized finish.

Russet potatoes are the best choice for this recipe because of their high starch content, which helps create a crisp exterior while keeping the inside tender. If you prefer a creamier texture, Yukon Gold potatoes are a great alternative.

Yellow onions add a mild, slightly sweet flavor that complements the potatoes beautifully. If you love a more intense onion taste, red onions or even shallots can be used instead.

Olive oil is key to getting that golden, crispy texture. Be generous with it, ensuring that every potato slice is well-coated. For an extra depth of flavor, you can mix in a little melted butter as well.

Seasonings make all the difference. A simple mix of salt, black pepper, and garlic powder enhances the natural flavors, but you can also add smoked paprika or cayenne for a bit of heat.

A large baking sheet is essential for spreading out the potatoes and onions in a single layer, allowing them to roast evenly without steaming.

How To Make This Oven-Fried Potatoes & Onions

Making this dish is incredibly simple, and the oven does most of the work for you.

Start by preheating your oven to 425°F. While the oven heats, scrub and slice your potatoes into thin, even rounds. Keeping the slices uniform ensures they cook evenly and crisp up nicely.

Next, peel and thinly slice your onions. The thinner they are, the more they'll caramelize and become deliciously sweet and golden.

In a large bowl, toss the sliced potatoes and onions with olive oil, salt, black pepper, and garlic powder. Stir well to ensure every piece is evenly coated. For an extra crisp factor, let them sit for a few minutes while the oven finishes preheating.

Spread the mixture in a single layer on a baking sheet. Overcrowding the pan will cause steaming instead of crisping, so if necessary, use two sheets to give everything enough space.

Bake for 25-30 minutes, flipping halfway through to ensure both sides get evenly browned. The edges should be golden and crispy, while the onions become beautifully caramelized.

Storage Options

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To keep them from getting soggy, place a paper towel in the container to absorb excess moisture.

For longer storage, you can freeze them. Spread the cooked potatoes and onions on a baking sheet and freeze until solid before transferring to a freezer-safe bag. They’ll keep for up to 2 months.

To reheat, bake them at 400°F for about 10 minutes, or until they regain their crispiness. Avoid microwaving, as it tends to make them soft rather than crispy.

Variations and Substitutions

This recipe is highly adaptable, allowing you to tweak it to your taste or dietary preferences.

For a heartier dish, add sliced smoked sausage or crumbled bacon before baking. The fat from the meat will infuse the potatoes and onions with incredible flavor.

If you love herbs, sprinkle in fresh rosemary or thyme before roasting. They add an aromatic depth that pairs beautifully with the caramelized onions.

Swap out olive oil for melted butter if you prefer a richer taste. A combination of both creates an even more indulgent, crispy finish.

For a spicy kick, add a pinch of cayenne pepper or red pepper flakes. This balances out the sweetness of the onions and gives the dish a little heat.

No russet potatoes on hand? Try sweet potatoes for a slightly sweeter, more nutrient-dense variation that roasts up just as beautifully.

Experiment with different flavors and add-ins to make this dish your own. No matter how you customize it, oven-fried potatoes & onions are sure to become a household favorite.
