Ingredients
To make the most glorious Mashed Sweet Potatoes with Miso Butter, you will need:
-
2 lbs. sweet potatoes (peeled and cut into 1-inch pieces): This creamy, vibrant root vegetable is a star of the show! With its luscious, orange flesh, it’s sweet, nutritious, and comforting.
-
1/4 cup (plus 2 Tbsp.) unsalted butter, softened: Rich and creamy, the butter adds a decadent touch to the wholesome sweetness of the potatoes.
-
1 Tbsp. miso paste: This fermented soy product introduces a unique umami flavor that will elevate your dish to new heights.
-
1/4 tsp. black pepper: A gentle hint of warmth that compliments the sweetness of the potatoes perfectly.
-
3/4 cup vegetable broth (warmed): This adds a touch of moisture and flavor, making your mashed potatoes irresistibly creamy.
-
1/2 tsp. kosher salt: Essential for bringing all the flavors together.
-
Fresh thyme leaves for garnish: These little green leaves provide a beautiful touch, both visually and in terms of aroma.
Step-by-Step Directions
Creating these mashed sweet potatoes with miso butter is a straightforward process that anyone can master. Follow these easy steps:
-
Begin by placing the sweet potato pieces in a large steamer basket over a pot of boiling water. The steam will gently cook the potatoes until they are fork-tender. This usually takes about 30 minutes, and you’ll be able to breathe in that comforting aroma.
-
While the potatoes are steaming, prepare the Miso Butter. In a small bowl, use a fork to cream together the softened butter and miso paste until they form a smooth mixture. Sprinkle in the black pepper and set this luscious mixture aside.
-
After the sweet potatoes are tender, it’s time to mash! Use a potato masher or a ricer to mash the sweet potatoes until they reach a smooth and creamy consistency. For an even silkier texture, you could use a blender or food processor.
-
Add in the remaining 1/4 cup of softened butter along with the warmed vegetable broth and kosher salt. Mix until everything is combined and creamy.
-
Transfer the beautiful mashed sweet potatoes to a bowl and immediately top with the prepared Miso Butter. The residual heat will cause the butter to melt and create a beautiful sheen on top of your mashed masterpiece.
-
Finally, garnish with fresh thyme leaves to add an aromatic touch and elevate the presentation.
Tips & Tricks
- For extra flavor, consider adding a pinch of cinnamon or nutmeg while mashing the sweet potatoes. These spices bring warmth and depth to the dish.
