Miso Butter has become one of my favourite condiments, or rather flavouring ingredients, and I’ve been making a batch almost every week. I use it melted over sweet potatoes or steamed green beans, with grilled fish or salmon, to sautee mushrooms, as a dip with radishes and in many more ways. In this recipe, I will teach you how to make miso butter, freeze it and use it in different ways.
I’m so excited to share this recipe with you guys. It’s one of those ingredients you might spot in a hip Asian fusion restaurant but given how easy it is to make at home, I have no idea why I didn’t start whipping my own batch sooner. Better later than never!
What Is Miso Butter?
It’s pretty much what it sounds like – a mixture of miso paste and softened butter. I use a couple of other ingredients in my recipe but in its most basic form, it is just those two.
Miso butter is the most delicious and versatile condiment that is full of that savoury, salty umami flavour and can be used in many ways as a sauce, spread, filling or seasoning.
Miso is a Japanese paste made from fermented soybeans and koji (think of it as a fungus fermenting starter culture), plus rice, barley and other ingredients.
I have a whole article on miso and its nutritional profile here, but in a nutshell, it is a fermented food and even though its made from soybeans and say brown rice or barley, the fermentation reduces the number of antinutrients that are usually present in those foods and are sometimes avoided.
This tasty butter is gluten-free, keto and low-carb friendly and is high in vitamins A, K and D.
What Kind Of Miso Should I Use?
There are a few different types of miso on the market and it can be confusing as to which one to buy.
Ideally, you should be getting the unpasteurised, fresh fermented miso that is kept in the refrigerated section of the supermarket. This is when all that beneficial bacteria are alive and…well…beneficial. It also tastes better in my opinion.
If you can’t get fresh, unpasteurized miso, the paste you find in a packet in a pantry section of the store will still work as the flavour additive.
You can use white or brown miso paste in this recipe. Brown miso has a slightly stronger flavour and will give you a darker miso butter but either can be used. I used brown miso.
Where To Get Miso?
Fresh, unpasteurized miso paste is usually sold in a jar or a tub and you’re most likely to find it in health food stores and places that tend to sell healthy foods (e.g. Whole Foods, Harris Farm etc) and Asian grocers.
Although, these days you can usually find it in large supermarkets as well. Look for it near tofu or tempeh products in the refrigerated section. Otherwise, you can get it online and the pasteurised, packet miso is quite easy to find.
How To Make Miso Butter
For this recipe, I made a large batch of miso butter as I wanted to show you how to freeze it for later.
Often, I will whip up a couple of tablespoons of the stuff to use with grilled fish or veggies for dinner. But, it’s super handy to have ready-to-go miso butter in the fridge or freezer to save time.
For the most nutritious miso butter, you will need good quality, unsalted butter (ideally grass-fed) and unpasteurized miso paste (brown or white). I like to add a little Sriracha hot sauce and garlic to my batch but you can omit those if avoiding garlic or chili.
Step 1. Take the butter out of the fridge and cut it into cubes. Leave it to soften on the counter or you could pop it in a bowl in a microwave for 15-20 seconds or in a hot oven. Don’t melt the butter, just let it soften slightly.
Having said that, sometimes I use this recipe to make miso butter sauce, in which case I melt the butter and mix it with miso, Tamari and Sriracha and it’s fabulous over veggies, rice, quinoa or with grilled protein.
Step 2. Place all ingredients in a food processor and blend together until whipped and smooth. You might need to scrape the ingredients off the sides halfway. Have a little taste. Good, eh?
How to use miso butter
Or rather, how would you not use miso butter?
It’s incredible with baked or roasted vegetables (try my OMG-so-good miso butter baked sweet potatoes!) or stirred through steamed vegetables of any kind (especially green beans). I like sauteing mushrooms and onions in miso butter and adding it to scrambled eggs.
You can use it to make miso butter with fish or salmon (melted over the top) or bake miso butter chicken.
Try grilled steak with miso butter sauce or stir it through quinoa or brown rice for a tasty plant-based dish. I also love adding a dollop inside portobello mushrooms and roasting, grilling or BBQing those till the butter is melted into the flesh of the mushroom.
Stir it through zucchini or any noodles of choice and add to flavour cauliflower rice (or regular rice).
Use it as a dip with radishes, raw carrots or spread over rice crackers or sourdough toast.
Finally, add a dollop to any stew or soup to enhance its flavour and texture.
How To Store & Freeze Miso Butter
Once the butter is whipped, transfer it into a container or a bowl and store in the fridge covered with a lid. It will keep quite well in the fridge (a few weeks, similarly to butter) but for longer storage, you can freeze it.
In fact, I like freezing it in a log shape, which you could then move to the fridge for everyday use.
Cut a large piece of parchment paper and place the miso butter in the middle. Shape it into an oval lump, then wrap gently into a log or a roll with parchment paper and twist the ends. It will look like a confetti bonbon.
Pop it in the freezer and voila! After an hour or so, the butter will freeze in this shape and next time you unwrap it, you can simply slice off as little or as much as you need.
