Preheat the Oven: Set your oven to 425°F (220°C).
Prepare the Potatoes: In a large bowl, toss the diced potatoes with olive oil, paprika, garlic powder, onion powder, cumin, chili powder, black pepper, and salt until well coated.
Roast the Potatoes: Spread the potatoes in a single layer on a lined baking sheet. Roast for 35-40 minutes, flipping halfway through for even crispiness.
Serve and Enjoy: Remove from the oven and sprinkle with extra salt if needed. Serve immediately as a side dish, breakfast hash, or a flavorful snack.
