The Magic of One Spoonful of Dashi Butter

The idea of “dashi butter” may sound a little unexpected at first — but also irresistibly delicious, right? We have a feeling many of you are just as intrigued as we are.

This feature began with a suggestion from one of Kayanoya’s recipe developers. A passionate butter lover herself, she had a realization one day:
“What if you combined dashi and butter? Wouldn’t that make dishes delicious without needing much seasoning?”

So she gave Kayanoya Dashi × butter a try. The result was even more delicious—and easier—than expected, so we just had to share it with you.
Spread it, sauté with it, toss it into dishes — the possibilities are endless. These dashi butter recipes might just revolutionize the way you cook.

Simply Mix and Enjoy: How to Make Dashi Butter

Start with 1 packet of Kayanoya Original Dashi Stock Powder and 50 g (about 3½ tablespoons) of unsalted butter.

Making it couldn't be easier. Simply soften the butter at room temperature, open the dashi packet, and mix the contents into the butter until well combined.

If you're making extra, try shaping the dashi butter into a log with plastic wrap and keeping it in the freezer. It's a handy way to have it ready whenever you need it—just slice off the amount you'd like to use.

How to Use Dashi Butter Packed with Umami

A quick taste of the lightly speckled dashi butter reveals its rich, mellow flavor and deep umami. Simply replacing your usual butter with dashi butter can add an extra layer of depth to everyday dishes. It's easy to imagine countless ways to enjoy it.

First, let's start with the most classic pairing for butter: bread.

As the dashi butter melts into warm toast, its distinctive aroma gently rises, while its subtle umami and natural sweetness soak into every bite. Even without toppings like cheese, it adds satisfying flavor and richness—making it a wonderful option for busy mornings.

Next, let's see how dashi butter can be used in place of cooking oil in everyday dishes.

Even thinly sliced meat becomes wonderfully flavorful when quickly sautéed in gently melted dashi butter. The butter's umami blends naturally with the meat, creating a rich and satisfying finish. A squeeze of lemon brightens the flavors and brings everything into balance.

For 200 g beef, use 10 g dashi butter.

This simple pasta is satisfying even when you're short on time or don't have many ingredients on hand. Simply toss freshly cooked pasta with a mixture of pasta water and dashi butter.

The result is surprisingly flavorful, with a rich, savory depth and just the right balance of seasoning. It's hard to believe that something so simple can deliver such a well-rounded taste.

For 80 g pasta, use 15–25 g dashi butter.

Dashi butter is just as delicious in fried rice, over a bowl of rice with a raw egg, or melted onto grilled mochi or roasted daikon. Because it's made with dashi, it pairs naturally with a wide variety of ingredients, bringing extra depth and flavor to everyday dishes.
