What Kind of Potatoes Should I Use?

When it comes to oven-fried potatoes, not all varieties work the same way. I prefer using Yukon Gold or baby potatoes because they have a naturally buttery flavor and hold their shape well when roasted. Their thin skins get beautifully crisp without needing to be peeled. Russet potatoes are another option if you want an extra crispy texture, though they can be slightly drier inside. Red potatoes work too, offering a firmer bite and a pop of color. No matter which type you choose, cutting them into uniform sizes ensures even cooking.

Options for Substitutions

If you need to tweak this recipe to fit your pantry or preferences, here are some great swaps:

• Potatoes – Sweet potatoes can be used for a slightly caramelized, sweeter version.
• Onions – Swap red onions for yellow or white onions, or use shallots for a milder flavor.
• Oil – Olive oil works best, but avocado oil or melted butter will add a different depth of flavor.
• Seasonings – Experiment with garlic powder, smoked paprika, or even Cajun seasoning for a spicy twist.
• Herbs – Fresh rosemary, thyme, or parsley add a lovely finishing touch.

Ingredients for Crispy Oven-Fried Potatoes & Onions

Each ingredient in this recipe plays a crucial role in achieving the perfect balance of flavor and texture. Here’s why you need them:

• Baby or Yukon Gold potatoes – Their creamy interior and crispy skin make them ideal for roasting.
• Red or yellow onions – Adds sweetness and depth, caramelizing beautifully in the oven.
• Olive oil – Helps crisp up the potatoes and enhances their natural flavor.
• Garlic powder – A hint of savory depth without overpowering the dish.
• Paprika – Brings a subtle smokiness and a touch of warmth.
• Salt & black pepper – Essential for seasoning and bringing out the natural flavors.
• Fresh parsley (optional) – Adds a bright, fresh contrast to the crispy potatoes.

Step 1: Prep the Ingredients

Preheat your oven to 425°F (220°C). Wash the potatoes thoroughly and pat them dry. Cut them into evenly sized wedges or halves to ensure they cook at the same rate. Slice the onions into thick pieces—this helps them caramelize without burning too quickly.

---

Step 2: Season Everything

In a large mixing bowl, toss the potatoes and onions with olive oil, garlic powder, paprika, salt, and black pepper. Make sure everything is well coated so the flavors infuse properly while roasting.

---

Step 3: Arrange on a Baking Sheet

Spread the seasoned potatoes and onions in a single layer on a large baking sheet. Avoid overcrowding—this helps the potatoes crisp up rather than steam. If necessary, use two baking sheets to allow for proper air circulation.

---

Step 4: Roast to Perfection

Place the baking sheet in the preheated oven and roast for 35-40 minutes, flipping the potatoes halfway through to ensure even browning. The potatoes should be golden brown and crispy on the outside, while the onions should be caramelized and slightly charred.

---

Step 5: Garnish and Serve

Once out of the oven, sprinkle fresh parsley over the top for a burst of color and freshness. Serve immediately while hot and crispy. Enjoy as a side dish, or even as a hearty snack on its own!

How Long to Cook Crispy Oven-Fried Potatoes & Onions

The key to perfectly crispy potatoes is roasting them at 425°F (220°C) for about 35-40 minutes. Flipping them halfway through ensures even browning on all sides. If you want extra crispiness, you can leave them in for an additional 5 minutes, but be careful not to overcook the onions.

Tips for Perfect Crispy Oven-Fried Potatoes & Onions

• Use a hot oven – A high temperature helps create that irresistible crispiness.
• Don’t overcrowd the pan – Giving the potatoes space prevents them from steaming and helps them crisp up.
• Dry the potatoes before roasting – Moisture prevents browning, so pat them dry with a paper towel after washing.
• Toss halfway through cooking – Flipping ensures even browning and caramelization.
• Use the right oil – Olive oil is great, but avocado oil or melted butter can enhance the crispiness.
• Try a preheated baking sheet – Placing potatoes on a hot pan jumpstarts the crisping process.
• For extra crunch, use cornstarch – A light dusting of cornstarch before roasting adds a crispy coating.

Watch Out for These Mistakes While Cooking

Even a simple dish like oven-fried potatoes and onions can go wrong if you’re not careful. Here are a few common mistakes to avoid:

• Cutting potatoes unevenly – Different sizes cook at different rates, leading to some pieces being burnt while others remain undercooked.
• Not drying the potatoes – Excess moisture prevents them from crisping up properly.
• Overcrowding the baking sheet – This causes steaming instead of roasting, resulting in soft potatoes instead of crispy ones.
• Skipping the flip – Flipping the potatoes halfway ensures an even golden crust on all sides.
• Using too little oil – While you don’t want greasy potatoes, a good coating of oil is necessary for proper browning and crispiness.
• Cooking at too low a temperature – Anything below 400°F won’t give you that crispy, golden finish.
• Ignoring the onions – Onions can burn quickly if cut too small or placed on the edges of the pan. Keep an eye on them!
• Forgetting the seasoning – Salt, pepper, and spices bring out the best flavors—season generously!

Frequently Asked Questions

1. Can I use sweet potatoes instead of regular potatoes?

Yes! Sweet potatoes will give a slightly caramelized, sweeter flavor. Just keep in mind that they cook a little faster, so check them around the 30-minute mark.

2. How do I make the potatoes extra crispy?

For extra crunch, soak the cut potatoes in cold water for 30 minutes before baking. Then, dry them thoroughly and toss them with a light coating of cornstarch before adding oil and seasonings.

3. Can I cook these potatoes in an air fryer?

Absolutely! Air fry at 400°F (200°C) for about 20-25 minutes, shaking the basket halfway through for even crispiness.

4. What’s the best oil to use for roasting?

Olive oil is great for flavor, but avocado oil or vegetable oil work well too since they have a higher smoke point.

This usually happens if the baking sheet is overcrowded or the oven temperature is too low. Spread the potatoes in a single layer with space between them, and make sure your oven is set to at least 425°F (220°C).
