I Swore by Kerrygold, But This Costco Butter Just Won Me Over (It's Cheaper)

I’m a big fan of Kerrygold butter. Professional bakers and chefs agree it's the best butter you can buy. So I usually pick up a four-pack when I go to Costco. On a recent trip to the store, I spied Kirkland Signature Grass-Fed Butter nearby. I was curious, so on a whim, I purchased it, and I’m so glad I did: It’s better—and cheaper!—than Kerrygold.

Why I'm Only Buying Kirkland Signature Grass-Fed Butter Going Forward

At my local Costco, Kerrygold costs $16.99, while Kirkland's costs only $11.99. That’s two pounds of butter for $5 cheaper. With grocery prices as high as they are these days, this is a big difference.

Just like Kerrygold, which has a beautiful yellow hue, Kirkland's is so beautifully yellow, it's almost orange. The butter gets its gold hue from the milk of cows that are on a 95 percent grass-fed diet in New Zealand. And as an author who wrote a book about cheese from around the world, I know that these New Zealand cows are well cared for, which means the products made with their milk are delicious.

As soon as I brought the butter home, I used it to make garlic bread, and it turned out to be one of the best garlic breads I’ve ever made. You could really taste the butter.

Then I melted some into scrambled eggs, which gave them the richest, most luscious texture. I’ve used it to make a yummy roux for macaroni and cheese, and a fantastic hollandaise sauce for eggs Benedict. You get the gist—no matter what I used the butter in, it was delicious. I can’t wait to try it on Christmas Day to make a béarnaise sauce for our traditional steak dinner. Of course, we're going to smear it on our rolls, too.

Take note that Kirkland's butter is salted—there isn't an unsalted option—so I'm extra careful about adding salt when I cook or bake with it. I hope Costco comes out with an unsalted version of this delicious butter. I'd be first in line to buy it.

In any case, my family has officially switched our go-to butter to Kirkland's.
