Ingredients Notes

The magic of these oven-fried potatoes & onions lies in a handful of simple ingredients that come together to create an incredibly flavorful dish.

Russet potatoes are my top choice for this recipe. Their starchy texture crisps up beautifully in the oven, giving you that perfect golden-brown exterior. If you prefer a waxier potato, Yukon Golds are a great alternative.

Yellow onions add a sweet, caramelized contrast to the crispy potatoes. You can also use red onions for a slightly bolder flavor, but yellow onions give the best balance of sweetness and depth.

Olive oil is the key to crispiness without deep frying. It helps the potatoes brown evenly and adds a subtle richness. You can also use avocado oil or melted butter for a slightly different flavor profile.

Seasonings make all the difference. I stick with a classic blend of salt, black pepper, garlic powder, and smoked paprika to enhance the natural flavors. If you love a little heat, try adding a pinch of cayenne pepper.

A large baking sheet is essential for even cooking. Make sure to spread the potatoes out in a single layer so they crisp up instead of steaming.

How To Make These Oven-Fried Potatoes & Onions

Making oven-fried potatoes & onions is as simple as chopping, seasoning, and roasting. Here’s how it all comes together:

Start by preheating your oven to 425°F (220°C). This high heat is key to achieving crispy potatoes. Line a large baking sheet with parchment paper or lightly grease it with oil.

Next, wash and slice the potatoes into thin rounds or wedges, about ¼-inch thick. Keeping the slices uniform ensures they cook evenly. Slice the onions into thin strips to match the size of your potatoes.

In a large bowl, toss the potatoes and onions with olive oil and seasonings. Make sure everything is well coated—this helps with crisping and flavor.

Spread the mixture evenly on the baking sheet in a single layer. If needed, use two sheets to prevent overcrowding, which can lead to steaming instead of crisping.

Roast for 30-40 minutes, flipping the potatoes halfway through to ensure even browning. The edges should be golden and crispy, and the onions should be soft and caramelized.

Once done, let them cool slightly before serving. Sprinkle with fresh herbs like parsley or chives for an extra pop of flavor.

Storage Options

If you have leftovers (which is rare!), you can store them in an airtight container in the fridge for up to 4 days. Just make sure they’re completely cooled before storing to prevent sogginess.

For longer storage, freeze them in a single layer on a baking sheet before transferring them to a freezer-safe bag. They’ll keep for up to 3 months this way.

To reheat, bake at 400°F (200°C) for about 10-15 minutes, or until crispy again. You can also reheat them in an air fryer for a quick and easy refresh.

Variations and Substitutions

The beauty of oven-fried potatoes & onions is that they’re incredibly adaptable. Here are a few ways to switch things up:

For extra crunch, add grated Parmesan cheese in the last 10 minutes of baking. It adds a savory, crispy topping that takes these potatoes to the next level.

Switch up the seasoning! Try using Italian seasoning for a herby twist, or go bold with a Cajun spice blend for a little heat.

Make it a full meal by adding sliced sausage or diced bell peppers to the mix before roasting. It turns this side dish into a hearty, one-pan dinner.

If you’re avoiding nightshades, swap out the potatoes for sweet potatoes or even parsnips for a different take on the dish.

No onions? No problem! Try using shallots or even leeks for a milder, more delicate flavor.

With so many ways to enjoy this recipe, there’s no wrong way to make it your own. Give it a try and let me know your favorite variation!
