Preheat your oven to 425°F (220°C).
Wash and peel the sweet potatoes.
Cut them into even-sized cubes or wedges.
Place the sweet potatoes in a large bowl.
Drizzle with olive oil and toss to coat evenly.
Sprinkle salt, pepper, paprika, and garlic powder over the sweet potatoes.
Toss again to ensure even seasoning.
Spread the sweet potatoes in a single layer on a baking sheet.
Roast in the oven for 30-35 minutes, flipping halfway through.
Once golden and tender, remove from the oven and garnish with fresh thyme.
