2 lbs sweet potatoes, peeled and cut into 1-inch cubes
3 tbsp extra virgin olive oil
1 tsp dried rosemary Shop
0.5 tsp garlic powder Shop
0.5 tsp salt
0.25 tsp black pepper

Instructions

1 Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup. In a large bowl, combine the cubed sweet potatoes with the extra virgin olive oil, ensuring each piece is lightly coated. The oil will help them crisp up beautifully in the oven.
2 Sprinkle the dried rosemary, garlic powder, salt, and black pepper over the olive oil-coated sweet potatoes. Toss everything together thoroughly for about 1-2 minutes until the seasonings are evenly distributed, creating a fragrant mixture.
3 Spread the seasoned sweet potato cubes in a single layer on the prepared baking sheet. Avoid overcrowding the pan, as this will steam the potatoes instead of roasting them, preventing them from developing a nice crisp exterior. Ensure there's some space between each cube for optimal air circulation.
4 Roast the sweet potatoes in the preheated oven for 30-35 minutes, flipping them halfway through the cooking time. They are ready when they are fork-tender and have developed lovely caramelized edges with a golden-brown hue.
5 Carefully remove the baking sheet from the oven. Allow the roasted sweet potatoes to cool slightly for a few minutes before serving. They are best enjoyed warm as a delicious and satisfying side dish.

Tips & Notes

Crush the dried rosemary between your fingers before sprinkling it on. Crushed rosemary coats the cubes evenly instead of sitting on top and scorching at 400°F.
Buy garlic powder and dried rosemary labeled gluten-free. Single spices are gluten-free by nature, but some brands pack them on lines shared with flour-based blends.
Reheat leftovers in a 400°F oven or an air fryer for 8-10 minutes. The microwave turns the edges soft.
