An Unexpected Fan
My nephew, a notoriously picky eater who turns his nose up at anything with visible onions, surprised us all when he devoured a whole plate of these fried potatoes. He didn’t even notice the onions—they had softened and caramelized so perfectly that they simply melted into the potatoes, leaving behind only their sweet, savory essence. Now, it’s his most-requested dish when he visits.
What Makes It Special
Russet potatoes – Their high starch content ensures a crispy exterior and fluffy interior.
Yellow onions – Mild and sweet, they caramelize beautifully without overpowering the dish.
Garlic powder & red pepper flakes (optional) – Add depth and a subtle kick.
Chives (optional garnish) – A fresh, oniony finish that brightens the dish.
Making It Happen
Heat the oil in a large cast-iron skillet or sauté pan over medium-high heat. You want it shimmering but not smoking—just hot enough to crisp the potatoes without burning them.
Slice the potatoes and onions about ¼-inch thick. Uniformity is key here—too thick, and they won’t cook evenly; too thin, and they might burn.
Carefully add the potatoes and onions to the hot oil. They’ll sizzle immediately, a sign they’re on their way to crispy perfection. Season generously with salt, pepper, garlic powder, and red pepper flakes if using.
Cook, stirring often, until the potatoes are deeply golden and tender (about 10–15 minutes). For extra creaminess, cover the skillet briefly to steam them slightly.
Drain on paper towels to remove excess oil, then sprinkle with fresh chives for a pop of color and flavor.
You Must Know
✔ Use a well-seasoned cast-iron skillet for even heat distribution and the best browning.
✔ Don’t overcrowd the pan—cook in batches if needed to avoid steaming instead of frying.
✔ Adjust heat as needed—if the potatoes brown too quickly, lower the heat slightly.
✔ Let excess oil drain for a crispier texture.
Serving Ideas
Breakfast: Pair with sunny-side-up eggs and crispy bacon.
Lunch/Dinner: Serve alongside grilled sausages or roasted chicken.
Dipping sauces: Ketchup, garlic aioli, or spicy mayo.
Drinks: A cold lager, sweet iced tea, or sparkling water with lemon.
Make It Different
Buttery upgrade: Swap half the oil for butter (watch for burning).
Bacon lovers: Fry in bacon fat and crumble cooked bacon on top.
Herb variations: Try rosemary, thyme, or smoked paprika.
Spicy kick: Add cayenne or diced jalapeños.
Storage & Reheating Tips
Fridge: Store in an airtight container for up to 3 days.
Reheat: Spread on a baking sheet and crisp in a 375°F oven for 5–10 minutes, or quickly re-fry in a skillet. Avoid microwaving—it makes them soggy.
Success Tips
Pat potatoes dry before frying to prevent oil splatter.
Season in layers—a little salt while cooking, and a pinch more at the end.
For extra crispiness, press potatoes lightly in the pan to maximize contact with the heat.
Frequently Asked Questions

A: Yes! Toss potatoes and onions with a little oil and air-fry at 400°F for 15–20 minutes, shaking halfway.
Q: Why are my potatoes soggy?
A: Overcrowding the pan or not draining excess oil can lead to sogginess.
Q: Can I prep this ahead?
