How to Make Savory Miso Butter Roasted Sweet Potatoes: A Flavorful Delight

1. Preheat your oven to 425°F and line a large baking sheet with parchment paper or a silicone baking mat.
2. In a small bowl, whisk together the melted butter, miso paste, soy sauce, maple syrup, rice vinegar, smoked paprika, garlic powder, salt, and black pepper until smooth and well combined.
3. Place the cubed sweet potatoes in a large mixing bowl and pour the miso butter glaze over them. Toss gently to coat each piece evenly with the flavorful mixture.
4. Spread the coated sweet potatoes in a single layer on the prepared baking sheet, making sure they have space to roast evenly without overcrowding.
5. Roast in the preheated oven for 25 to 30 minutes, flipping the potatoes halfway through, until they are tender inside and caramelized on the edges.
6. Remove from the oven and transfer the sweet potatoes to a serving dish. Sprinkle with chopped fresh parsley for a pop of color and fresh flavor.
7. Serve warm as a delicious side to your favorite meals, enjoying the perfect balance of sweet, savory, and umami flavors.

Tips for the Best Results

• Use firm, evenly sized sweet potato cubes for uniform roasting and cooking.
• Don’t overcrowd the baking sheet; roasting in a single layer ensures crisp edges.
• Adjust the miso and soy sauce amounts to taste if you prefer a milder or stronger umami flavor.
• For extra crispiness, broil the sweet potatoes for 2-3 minutes at the end—just watch closely.
• Fresh parsley adds brightness, but toasted sesame seeds also make a delicious garnish.

Storage and Reheating

Store leftover miso butter roasted sweet potatoes in an airtight container in the refrigerator for up to 4 days. To reheat, warm them in a 350°F oven for 10 minutes or until heated through to maintain their crisp texture.

You can freeze roasted sweet potatoes for up to 2 months. Let them cool completely, spread on a baking sheet to freeze individually, then transfer to a freezer-safe bag. Reheat in the oven directly from frozen for best results.
