Roasted purple sweet potatoes with olive oil, paprika, garlic, and onion powder – crispy on the outside, tender inside, and packed with flavor.

Purple sweet potatoes, with their vibrant hue and naturally sweet, earthy flavor, are as stunning as they are delicious.
I first heard about purple sweet potatoes being a superfood while watching the documentary Live to 100: Secrets of the Blue Zones. It highlighted how centenarians in Okinawa, Japan, include these vibrant potatoes as a staple in their diet, contributing to their remarkable longevity.
Inspired by their simple yet wholesome way of eating, I decided to cook purple sweet potatoes at home using one of the easiest and healthiest methods – baking them with olive oil, salt, paprika, garlic, and onion powder. The result is a flavorful, nutrient-packed side dish that’s both satisfying and nourishing.

Recipe Tips
Cut Evenly: To ensure even cooking, cut the potatoes into uniform wedges or cubes.
Crispy Edges: For extra crispiness, bake at a high temperature (425°F/220°C) and finish with 2-3 minutes under the broiler.
Season Well: Toss the potatoes with spices and oil in a bowl before spreading them on the baking sheet for even coating.
Don’t Overcrowd: Spread the potatoes in a single layer with space between them to prevent steaming.
Enhance with Herbs: Add fresh rosemary or thyme during the last 10 minutes of baking for extra aroma and flavor.
