Purple sweet potatoes, also known as purple yams or Okinawan sweet potatoes, are a vibrant and nutritious root vegetable with a naturally purple flesh that comes from antioxidants called anthocyanins. When cooked, these potatoes have a mildly sweet flavor and a creamy texture, making them a versatile ingredient in both sweet and savory dishes. Roasting sweet potatoes brings out their flavor by caramelizing the natural sugars present in the potatoes. The high roasting heat causes the sugars to caramelize, creating a rich and sweet flavor profile. Additionally, roasting helps concentrate the sweet potatoes’ flavors, resulting in a more intense and satisfying taste.

Step-by-step: Roast purple potatoes

Peel if desired, then cut into cubes or wedges. Season – Toss the sweet potato cubes, sliced red onions, garlic powder with olive oil, salt, and pepper until evenly coated in a large bowl. Baking Tray – Spread the sweet potatoes and onions in a single layer on the prepared baking sheet.

Serve – Remove from the oven and let cool slightly before serving.
Tips for success
Evenly-Sized Pieces: Cut the sweet potatoes into uniform sizes to ensure even cooking. Coat Thoroughly: Toss the sweet potato pieces with the olive oil and seasonings until they are evenly coated to ensure they roast evenly and develop a crispy exterior. Single Layer: Spread the sweet potatoes out in a single layer on the baking sheet to allow for proper air circulation and even cooking. Preheated Oven: Ensure your oven is fully preheated before roasting the sweet potatoes to ensure they cook evenly and have a nice caramelization. Stirring Halfway Through: Stir the sweet potatoes halfway through the cooking time to ensure they cook evenly on all sides. Check for Doneness: Pierce the sweet potatoes with a fork to check for tenderness. They should be soft and easily pierced when done. Serve Immediately: For the best texture and flavor, serve the roasted sweet potatoes immediately after roasting.
