Oven-Fried Onion Potatoes

These oven-fried onion potatoes provide a tremendous amount of flavor. So they’re the ideal side for any simple meat dish.

We enjoy these fries with this honey-glazed chicken because it balances the sweet and savory. Another meat it’s good with is this pecan-crusted fish.

As someone who loves to cook but not stand in the kitchen too long, I use shortcuts whenever I can. That’s the reason I keep packets of onion soup mix on hand.

Oven-Fried Onion Potatoes Ingredients

You don’t need many ingredients to make these scrumptious fries. In fact, you only need three things: a package of frozen fries, vegetable oil, and onion soup mix.

Frozen fried potatoes, cooking oil, and onion soup mix

The first time I made these, I used olive oil. It was okay, but olive oil has a low burning point, and they didn’t turn out like I wanted.

So I recommend using another type of oil. We just happened to have canola oil.

How to Make Oven-Fried Onion Potatoes

These fries are so easy to make you’ll feel like you’re missing a step. But trust me when I say it truly is a very simple process.

Preheat your oven to 425 and spray your baking sheet with nonstick spray. You can skip this step, but if any of the potatoes are missing oil, they’ll stick.

Next, put the frozen fries in a large mixing bowl. If any of them are stuck together, break them apart.

Pour the oil over the fries and then sprinkle the soup mix over them. Toss them around the bowl until all of them are covered with the soup mix.

Finally, pour the fries onto the baking sheet and spread them out into a single layer.

Put them in the oven and bake for about 25 minutes or until they are golden brown. If you use a thinner style of fries, follow the instructions on the package.
