How to Cook Oven Fried Potatoes and Onions

Fire up your oven to a toasty 425F (220C). This high heat will help create those crispy, golden edges we all love on roasted potatoes.

Get ready to coat those veggies in deliciousness:
  • Potatoes
  • Onions
  • Olive oil

  • Optional herbs (like rosemary or thyme)

Use your hands or a big spoon to ensure every piece gets an even coating of oil and spices.

Step 3: Spread on Baking Sheet

Line a baking sheet with parchment paper for easy cleanup.

Spread out the potato and onion mixture in a single layer. Don’t crowd the pan – this helps each piece get perfectly crisp and golden.

Step 4: Roast to Perfection

Slide the baking sheet into the hot oven. Roast for 30-40 minutes, taking a moment halfway through to flip the vegetables.

You’re looking for a beautiful golden-brown color and crispy edges.
