This recipe elevates roasted sweet potatoes with an easy-to-make, delicious miso tahini butter. Whether served as a side dish or as a main beside a big salad, this recipe is always a hit.

This is my go-to roasted sweet potatoes recipe, and it’s one I come back to again and again. The miso tahini butter takes something simple and turns it into a dish that feels genuinely special, with almost no extra effort.
It takes about five minutes of hands-on prep, then the oven does the rest. While the sweet potatoes roast, I mix together the miso, tahini, and butter—just three ingredients—and I’ll admit, I usually sneak a little taste because it’s that good. That savory, umami-rich butter is the perfect counterbalance to the sweet potatoes’ natural sweetness.
I love how versatile this recipe is. I’ll turn it into a light vegetarian lunch with a green salad, serve it alongside a bigger dinner, or put it on the holiday table for Thanksgiving or Christmas (I usually halve them then, because there’s always so much food). They also reheat beautifully, which makes them ideal for meal prep.

What is tahini miso butter?
That little bowl up there is brimming with a secret sauce that transforms nearly everything. Made of the three ingredients in the title, it couldn’t be any easier to whip up. Stir them together, and you’ve made a little potion that will give you a big bang for your cooking buck.
This recipe makes enough for the baked sweet potatoes. But you can easily make it in larger quantities and keep it in your fridge to spice up all your meals. Try it with roasted vegetables (like my miso butter roasted radishes ), steak, or sauteed mushrooms .
