💜 What Are Best Purple Sweet Potato Recipe?
Purple sweet potatoes—often called Okinawan sweet potatoes or Stokes Purple potatoes—have a deep, violet flesh that gets even brighter when cooked. Native to Central and South America but widely popular in Hawaii and parts of Asia, these tubers have been gaining attention across the U.S. for their unique color and high antioxidant content.
Compared to orange sweet potatoes, purple varieties tend to be slightly drier and starchier. That’s actually a good thing when roasting—they hold their shape beautifully and crisp up nicely on the edges.
🛒 Ingredients (Serves 4)
- 2 large purple sweet potatoes, scrubbed and dried
- 2 tablespoons olive oil
- 1 teaspoon sea salt
- ½ teaspoon black pepper
- 1 teaspoon garlic powder
- ½ teaspoon paprika
- 1 teaspoon fresh rosemary or thyme (optional)
- Fresh parsley, chopped (for garnish)
🧑🍳 Step-by-Step Instructions
Step 1: Preheat Your Oven
Set your oven to 400°F (200°C). Line a large baking sheet with parchment paper or lightly grease it.
Step 2: Slice the Potatoes
Using a sharp knife or mandoline, cut the sweet potatoes into ½-inch thick wedges or rounds. Keeping the skin on adds texture, fiber, and visual contrast.
Step 3: Season Generously
In a large bowl, toss the potato slices with olive oil, garlic powder, paprika, salt, and pepper until evenly coated. If using rosemary or thyme, mix those in now.
Step 4: Spread on the Pan
Arrange the potatoes in a single layer on your prepared baking sheet. Avoid overcrowding to ensure even browning.
Step 5: Roast to Perfection
Roast for 25 to 30 minutes, flipping halfway through, until the edges are crisp and the centers are fork-tender. Depending on your oven and thickness, check around the 20-minute mark.
Step 6: Finish & Serve
Sprinkle with fresh parsley before serving. Serve warm as a side, snack, or base for bowls.
