Step-by-Step Beginner-Friendly Instructions

Preheat & Prep: Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Cube the Potatoes: Carefully cut your sweet potatoes into 1-inch, uniform cubes to ensure even roasting. 🔪
Season: Toss the cubes in a large bowl with a splash of oil, salt, and pepper. Spread them in a single layer on the baking sheet.
Roast: Bake for 25–30 minutes, flipping halfway through, until the edges are golden brown and tender inside.
Make the Butter: While the potatoes roast, whisk together the softened butter, miso, maple syrup, and rice vinegar in a small bowl until smooth.
Combine & Serve: Once the potatoes are hot out of the oven, toss them immediately with the miso butter glaze until coated. Sprinkle with green onions and sesame seeds before serving! 😋

💡 Pro Tips Section

Storage: Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or air fryer to regain crispiness.
Perfect Texture: Ensure the potatoes are dry after washing to achieve maximum caramelization rather than steaming.
Customization: If you love a little heat, add a half-teaspoon of chili flakes or sriracha to the butter mixture.

Variations

Want to turn this into a main dish? Add some roasted chicken thighs seasoned with soy sauce to the same baking sheet for an easy one-pan meal. The juices from the chicken will only enhance the miso butter glaze.

FAQ

Can I use red miso? Yes, but be aware that red miso is much saltier and stronger than white miso. Reduce the amount by half if using a darker variety.

Is this recipe vegan? Simply substitute the dairy butter with a high-quality plant-based butter stick, and it remains perfectly delicious!
