- 2 pounds Russet Potatoes (peeled and cut into 1‑inch cubes)
- 1 large Yellow Onion (thinly sliced)
- 3 tablespoons Olive Oil (extra‑virgin, for roasting potatoes)
- 2 tablespoons Unsalted Butter (cut into small pieces, for caramelizing onions)

Instructions
Prep Potatoes
Wash, peel, and cut the russet potatoes into uniform 1‑inch cubes. Place them in a large mixing bowl and rinse under cold water to remove excess starch, then pat dry with a clean kitchen towel.

Add 3 Tbsp olive oil, 1 tsp sea salt, ½ tsp black pepper, and the thyme leaves to the bowl. Toss until every cube is lightly coated.

Roast Potatoes
Spread the seasoned potatoes in a single layer on a baking sheet. Roast in a pre‑heated oven at 425°F for 30 minutes, turning once halfway through for even browning.

While potatoes roast, heat a large skillet over medium‑low heat. Add 2 Tbsp butter and let it melt, then add the sliced onion. Sprinkle a pinch of salt and cook, stirring occasionally, for 15 minutes until the onion is deep golden and sweet.
Time: PT15M
Combine and Finish
When the potatoes are crisp and golden, remove them from the oven. Transfer to a serving platter, top with the caramelized onions, and finish with a light drizzle of olive oil and a sprinkle of flaky sea salt.

Troubleshooting
Potatoes turn out soggy instead of crisp.
Make sure the potatoes are completely dry before oiling, spread them in a single layer, and keep the oven temperature at 425°F. Increase roasting time by 5‑10 minutes if needed.
Onions burn before becoming sweet.
Reduce the heat to low, add a splash of water or a pinch of sugar, and stir more frequently. Caramelization should be slow and gradual.
Storage
Refrigerator: Store in an airtight container for up to 3 days; reheat in a hot oven to restore crispness.
Freezer: Not recommended – texture degrades after freezing.
Room temperature: Can sit at room temperature for up to 2 hours; keep covered.
Make-Ahead Tips
- Slice the onion a few hours ahead and store in a sealed bag in the fridge.
- Par‑cook potatoes for 10 minutes, cool, then finish roasting just before serving.

Low‑heat caramelization slowly breaks down the onion’s natural sugars, creating a deep, sweet flavor and a silky texture that a quick sauté cannot achieve. This method also prevents the onions from turning bitter.
Can I make the crispy roasted potatoes with caramelized onion ahead of time and how should I store them?
Yes, you can roast the potatoes and caramelize the onions up to a day ahead. Store each component separately in airtight containers in the refrigerator, then reheat the potatoes in a hot oven (425°F) for 5‑10 minutes and gently warm the onions on the stovetop before serving.
What texture and appearance should I look for when the potatoes are done?
The potatoes should be golden‑brown and crunchy on the outside while remaining fluffy inside. A fork should pierce the interior easily, and the surface should have a glossy sheen from the olive oil.
