Loaded Japanese Sweet Potato

Purple Japanese Sweet Potato with all the fixins!

I love a good baked potato. While my all-time favorite comes from the legendary House of Prime Rib in San Francisco, I wanted to create a healthier, weeknight-friendly version featuring Japanese purple sweet potatoes—rich in flavor, nutrients, and vibrant color.

What’s so special about Japanese purple sweet potatoes?

There are many varieties of purple potatoes, but the most common type you’ll find in the U.S. is the Murasaki sweet potato. It’s naturally sweet, with a slightly nutty flavor and a firm texture that holds up beautifully when baked. You can find different varieties at your local Asian market or grocery store, and I highly recommend trying them all!

If you come across the Okinawan Japanese sweet potato, you’re in for a treat. This variety is packed with antioxidants and health benefits, as highlighted in the have amazing Blue Zones Kitchen cookbook. Curious about different types of potatoes, learn more here!

How to enjoy your roasted potato:

Once roasted, don’t skip the skin - it’s loaded with fiber and antioxidant! These loaded Japanese purple sweet potatoes are:

• A quick and easy weeknight dinner

• A hearty, nutritious lunch

• Perfect for appetizers when sliced into smaller portions

• A fun, color twist on potato salad

The Ultimate Topping: Miso Butter

Instead of regular butter, I love topping my baked potatoes with savory miso butter - a game changer that adds umami richness.

If you’re short on ingredients, classic butter works fine too. Want to try my easy miso butter recipe?. Get it here.

Feel free to get creative with the toppings! Whether you add toasted sesame seeds, scallions, furikake, or a drizzle of honey, the possibilities are endless. What’s your favorite way to top a baked sweet potato? Let me know in the comments!

Turn an ordinary potato into an entire meal that's both satisfying and healthy.

Ingredients

• 1-2 large Japanese sweet potatoes
• 1 tbsp extra virgin olive oil (recommend good quality olive oil)

Suggested Toppings

• Boiled broccoli, chopped in small pieces

Instructions

Directions

1. Preheat the oven to 425° F and set the rack on the top half of the oven.
2. Scrub the sweet potatoes well, removing any dirt or roots.
3. Dry well and prick the sweet potato all over, rub the outside with olive oil. Rub salt all over the potatoes.
4. Place the potatoes on a foil lined baking sheet.
5. Bake for 45 minutes to an hour, the potatoes will be done once you can easily prick them with a fork.
6. After the potatoes have cooled a bit, cut them down the middle and add miso butter and toppings.

Notes

Cooking time will vary depending on how large your potatoes are and how many you are cooking at once. Typically, you'll find that roasting a baked potato takes ~45-60 minutes. You'll know it's done when you can easily poke through the potato with a fork.
