For the Sweet Potatoes
• Sweet Potatoes – The star ingredient provides natural sweetness and a creamy texture; opt for small to medium-sized ones for individual servings (200-250g each).

For Garnishing
• Sesame Seeds – Offers a nutty flavor and extra crunch; black or white sesame seeds can be used or substituted with chia or pumpkin seeds if unavailable.

Step‑by‑Step Instructions for Miso Sweet Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 200°C (400°F). While it warms up, grab a baking tray and generously grease it with coconut or olive oil to ensure the sweet potatoes won’t stick. The warmth of the oven will help achieve that perfect crispy skin you desire for your Miso Sweet Potatoes.
Step 2: Prepare the Sweet Potatoes
Wash the sweet potatoes thoroughly, removing any dirt. Inspect each one and cut away any damaged spots. Once cleaned, lay them flat on the greased baking tray. Bake these sweet potatoes in the preheated oven for about 30 minutes, or until a knife slides easily through their tender flesh—this will indicate they’ve cooked perfectly.
Step 3: Mix the Miso Butter
While the sweet potatoes are baking, it’s time to prepare your flavorful miso butter. In a food processor, combine softened butter, brown miso, finely diced garlic, and Sriracha. Blend them until smooth and creamy. This savory mixture will add a delicious umami richness to your Miso Sweet Potatoes, so feel free to taste and adjust the seasoning as needed.
Step 4: Add the Miso Butter
As soon as the sweet potatoes are done baking, carefully remove them from the oven. Using a sharp knife, make a slit in one side of each sweet potato, allowing steam to escape. Add about a tablespoon of the miso butter inside each potato while it’s still hot, letting the butter melt into the sweet flesh. This will create an irresistible creamy texture.
Step 5: Garnish and Serve
Before serving your Miso Sweet Potatoes, sprinkle them with sesame seeds for added crunch and a lovely nutty flavor. For an extra touch, consider pairing them with a side salad of arugula dressed with olive oil and lemon juice. Serve these deliciously infused sweet potatoes warm, and watch as everyone at the table enjoys this delightful Japanese fusion side dish.
