Preheat the oven to 425°F. Line a baking sheet with parchment paper or foil for easier clean up.

Wash, peel and chop the sweet potatoes into ½-inch cubes. They should be the same size so that they cook evenly. This should give you about 6 cups worth.

Add the chopped sweet potatoes to a large bowl. Drizzle 3 Tbsp olive oil, and sprinkle 1 tsp salt, ½ tsp ground black pepper, ½ tsp paprika, ½ tsp garlic powder, ¼ tsp ground cumin, and ¼ tsp onion powder over the sweet potatoes. Toss the ingredients together evenly.

Spread the seasoned sweet potatoes onto the prepared baking sheet in a single layer. Place in the oven to bake at 425°F for 40 minutes, flipping them halfway through. The sweet potatoes will have crispy edges but still be tender inside when they’re done.
