This 2-ingredient miso butter is rich, nutty, and packed with umami flavor. It instantly upgrades baked potatoes, roasted vegetables, pasta, and more!
This miso butter recipe is 2-ingredient magic. A simple mixture of softened butter and white miso paste, it’s rich, creamy, and bursting with umami. I love keeping it on hand (or whipping it up at the last minute) to give simple meals an instant flavor upgrade. I’m currently obsessed with miso butter on a baked sweet potato, but it’s also wonderful on roasted vegetables, noodles, and more.
If you’re used to eating miso in miso soup, the combination of miso and butter might surprise you. But trust me—once you try this recipe, it’ll make perfect sense. The lightly sweet, savory miso and velvety butter are a match made in heaven.
Types of Miso Paste
Miso is a Japanese fermented soybean paste. Look for it in the refrigerated section of your grocery store. Though countless varieties of miso exist in Japan, in the US, you’ll likely find these three types:
- White miso (shiro miso) – Fermented with rice for less time than darker varieties, it has a mild, slightly sweet, and salty flavor.
- Yellow miso – Yellow miso is made by fermenting soybeans with barley. It’s bolder than white miso but still has a little sweetness.
- Red miso – Red miso is the most pungent—and least sweet—of these three types of miso. It’s fermented with barley or other grains for longer than the paler types.
I recommend using white miso in this recipe. Its sweeter, milder flavor pairs wonderfully with the butter! If you need to substitute another type of miso, start with half the amount and add more to taste.
How to Make Miso Butter
Making this compound butter couldn’t be easier: just mix 1 part white miso paste with 2 parts unsalted butter! You’ll end up with a creamy, thick paste.
Two tips:
- Make sure the butter is at room temperature so that the two ingredients are easy to combine. You can mix them with a spatula or mash with a fork if you have pockets of miso or butter that are difficult to break up.
- Use unsalted butter. Miso has a fairly high salt content on its own. Make sure to use unsalted butter for a balanced flavor. Salted butter will be too salty here.
