Add the onion slices to the bowl with the potatoes.
4. Season and Coat
Drizzle the olive oil over the potatoes and onions.
Add the garlic powder, paprika, thyme or rosemary (if using), salt, and pepper.
Toss everything together until the potatoes and onions are evenly coated.
5. Arrange on the Baking Sheet
Spread the seasoned potatoes and onions in a single layer on the prepared baking sheet. Avoid overcrowding to ensure even cooking and crispiness.
6. Bake
Place the baking sheet in the preheated oven and bake for 25–30 minutes.
Halfway through cooking, flip the potatoes and onions with a spatula to ensure even browning.
Continue baking until the potatoes are golden and crispy, and the onions are caramelized.
7. Serve
Remove from the oven and let cool for a few minutes.
Garnish with fresh parsley for a pop of color and flavor (optional).
Serve warm as a side dish or snack.
Tips for Perfect Oven-Fried Potatoes & Onions
Uniform Slices: Slice the potatoes evenly to ensure they cook at the same rate.
Dry the Potatoes: Pat the sliced potatoes dry with a paper towel before tossing with oil to help them crisp up.
Use High Heat: Baking at 425°F ensures a crispy, golden exterior.
Don’t Crowd the Pan: Overcrowding can lead to steaming instead of frying, so use two pans if needed.
