Step-by-Step Instructions

Step 1 — Preheat the Oven and Prepare the Baking Sheet

Preheat your oven to 425°F (220°C). This high heat is essential for achieving a crispy, fried-like texture on your Oven-Fried Potatoes with Onions. While the oven heats, line a large, rimmed baking sheet with parchment paper or aluminum foil for easy cleanup.

Step 2 — Cut the Potatoes and Onions

Scrub 2 pounds of russet or Yukon Gold potatoes clean. Cut them into ½-inch to ¾-inch cubes for even cooking. Simultaneously, slice one large yellow onion into similarly sized pieces or wedges. Keeping the sizes uniform ensures everything cooks at the same rate.

Step 3 — Season the Vegetables

In a large bowl, toss the potato and onion pieces with 3 tablespoons of olive oil or avocado oil. Season generously with salt, black pepper, and any other desired spices like garlic powder, smoked paprika, or dried rosemary. Coat every piece evenly for maximum flavor.

Step 4 — Arrange on the Baking Sheet

Spread the seasoned potatoes and onions in a single, even layer on the prepared baking sheet. It is crucial that the pieces are not crowded or overlapping; this allows hot air to circulate and promotes browning and crisping instead of steaming.

Step 5 — Roast Until Golden Brown

Place the baking sheet in the preheated oven and roast for 20 minutes. After 20 minutes, use a spatula to flip and stir the potatoes and onions. This prevents sticking and helps all sides become crispy. Return the sheet to the oven.

Step 6 — Check for Doneness and Serve

Continue roasting for another 15-20 minutes, or until the Oven-Fried Potatoes with Onions are deeply golden brown, crisp on the edges, and tender when pierced with a fork. The total cooking time is typically 35-40 minutes. Serve immediately while hot and crispy.

Common Mistakes to Avoid

• Mistake: Using the wrong potato type, like waxy red potatoes, which won’t get crispy. Fix: Opt for high-starch potatoes like Russets or Yukon Golds for the best texture in your Oven-Fried Potatoes with Onions.
• Mistake: Crowding the baking sheet, which steams the potatoes instead of roasting them. Fix: Use two sheets or roast in batches to ensure each piece has space for proper browning.
• Mistake: Skipping the preheating step for the baking sheet, resulting in soggy bottoms. Fix: Place your empty sheet in the oven as it preheats for a crispy start.
• Mistake: Not drying the potatoes thoroughly after cutting, introducing excess moisture. Fix: Pat the potato and onion pieces completely dry with a clean kitchen towel before tossing with oil.
• Mistake: Adding onions too early, causing them to burn before the potatoes are done. Fix: Add the onion slices partway through the cooking time for perfectly caramelized results.
• Mistake: Insufficient oil, leaving the potatoes dry and preventing crispiness. Fix: Coat every piece evenly with a generous amount of high-smoke-point oil like avocado or canola.
• Mistake: Neglecting to flip or toss the potatoes halfway through cooking. Fix: Give the pan a good shake or use a spatula to flip for all-around golden brown Oven-Fried Potatoes with Onions.
• Mistake: Seasoning with salt too early, which can draw out moisture and hinder browning. Fix: Season with salt right after removing the potatoes from the oven for the crispiest finish.
• Mistake: Baking at too low a temperature, leading to soft, steamed potatoes. Fix: A hot oven, around 425°F (220°C), is key for achieving a truly fried texture.

Storing Tips

• Fridge: Cool your Oven-Fried Potatoes with Onions completely, then store in an airtight container in the refrigerator for up to 4 days.
• Freezer: For longer storage, freeze the cooled potatoes and onions in a freezer-safe bag or container for up to 3 months. Note that the texture may become softer upon thawing.
• Reheat: For best results, reheat on a baking sheet in a 400°F (200°C) oven until hot and crispy, about 10-15 minutes. Ensure the internal temperature reaches 165°F (74°C) for food safety. You can also reheat in an air fryer for a quicker, crispier finish.

Always allow leftovers to cool to room temperature before refrigerating or freezing to maintain food quality and safety.

FAQs

Can I use a different type of potato for these Oven-Fried Potatoes with Onions?

Yes, russet potatoes are ideal for crispiness, but Yukon Golds also work well for a creamier texture. Avoid waxy potatoes like red potatoes as they won’t get as crispy. The key is to cut them uniformly for even cooking in your Oven-Fried Potatoes with Onions.

Why aren’t my potatoes getting crispy in the oven?

Ensure your oven is fully preheated and the potatoes are in a single, uncrowded layer on the baking sheet. Crowding causes steaming. Also, make sure the potatoes are thoroughly dried after washing and coated evenly with oil.

Can I prepare Oven-Fried Potatoes with Onions ahead of time?

You can cut the potatoes and onions a few hours ahead; keep them submerged in cold water to prevent browning. Drain and pat them completely dry before tossing with oil and seasoning. For best texture, bake immediately after preparing.
