Ingredients Notes

The beauty of this recipe lies in its simplicity, but each ingredient plays a key role in flavor and texture. Let’s break it down.

Russet potatoes are the star here. Their starchy nature makes them ideal for roasting—giving you those golden, crunchy edges and a fluffy center. You can use Yukon Golds if that’s what you have, but russets really shine when oven-fried.

Yellow onions bring a touch of sweetness as they caramelize in the oven. They balance the savory, salty notes from the potatoes and spices. Slice them a little thicker so they don’t burn before the potatoes are done.

Olive oil is the key to getting everything crisp without deep frying. It helps the potatoes brown beautifully while adding just a hint of flavor. Make sure to coat everything evenly so you don’t end up with dry or undercooked bits.

Paprika and garlic powder add depth without overpowering. You can switch it up with smoked paprika or add a dash of cayenne if you like a bit of heat. Salt and pepper, of course, are a must—don’t be shy with the seasoning!

As for equipment, you’ll need a large baking sheet (preferably metal for best crisping), parchment paper (optional for easier cleanup), and a big mixing bowl to toss everything together. A good sharp knife makes prep quicker too.

How To Make This Oven Fried Potatoes & Onions Recipe

Making oven fried potatoes and onions is easier than you think—just a few simple steps and your oven does the heavy lifting. Here’s how to make them perfectly every time.

Start by preheating your oven to 425°F (220°C). A hot oven is essential to get that crispy, caramelized finish. While it heats, wash and scrub your potatoes well, especially if you’re leaving the skins on (which I recommend for texture and nutrition).

Cut your potatoes into ½-inch cubes or wedges, depending on your preference. Try to keep the pieces uniform so they cook evenly. Slice your onions into thick strips, about ½ inch wide. Thinner slices will burn too fast in the hot oven.

Toss the cut potatoes and onions in a large bowl with olive oil, salt, pepper, paprika, and garlic powder. Make sure every piece is coated—this helps with even browning and flavor. Spread them out on your baking sheet in a single layer. Don’t overcrowd the pan—use two sheets if needed for extra crispiness.

Bake for 25 minutes, then use a spatula to flip the potatoes and onions. This helps both sides get that irresistible crispy finish. Return to the oven for another 20-25 minutes, or until golden brown and fork-tender. You’ll know they’re ready when the potatoes have deep golden edges and the onions are sweet and caramelized.

Once out of the oven, let them rest for a few minutes before serving. The residual heat will finish crisping them up. Sprinkle with extra salt or fresh herbs like parsley or thyme if you like.

From start to finish, this dish takes about 50 minutes, but most of that is hands-off time. It’s easy, satisfying, and makes your kitchen smell amazing.

Storage Options

Leftovers? Lucky you! These oven fried potatoes and onions store beautifully and reheat like a dream.

To store, let them cool completely, then transfer to an airtight container. They’ll keep in the fridge for up to 4 days. For best results, layer them with parchment paper to prevent sticking.

You can also freeze them if needed. Place cooled potatoes and onions on a baking sheet in a single layer and freeze until solid. Then transfer to a freezer-safe bag or container. They’ll last about 2 months this way.

When it comes to reheating, skip the microwave if you want to keep that crispy texture. Instead, reheat them in a hot skillet with a touch of oil or pop them in a 400°F oven for 10–15 minutes until warmed through and re-crisped.

These also make great leftovers for breakfast—try reheating and topping with a fried egg!

Variations and Substitutions

This recipe is endlessly customizable. Once you’ve mastered the basic version, feel free to play around with flavors and ingredients.

Swap the potatoes for sweet potatoes for a slightly sweeter twist with a caramelized finish. Just keep an eye on them—they tend to cook a little faster.

Not a fan of onions? Try bell peppers instead! They roast beautifully and add a pop of color and natural sweetness. Or go half and half with onions for a balanced blend.

Add protein to make this a full meal—sliced smoked sausage, bacon, or even leftover rotisserie chicken can be tossed in for a hearty one-pan dish. Add them halfway through roasting so they don’t dry out.

You can also change up the seasoning. Go Mediterranean with oregano, thyme, and a sprinkle of feta cheese, or try a Tex-Mex vibe with cumin, chili powder, and a drizzle of lime juice before serving.

Don’t be afraid to experiment! This recipe is forgiving, flexible, and always delicious.
