In the vast range of products offered by Costco, one has managed to conquer the most demanding palates: professional chefs agree that the best Costco product is pure Irish Kerrygold butter. This intensely flavored, creamy-textured ingredient is considered by many to be a culinary gem, ideal for both savory dishes and desserts.

Kerrygold butter is made with milk from grass-fed cows in Ireland. This natural diet gives it its characteristic golden color and a smooth, creamy, and slightly sweet flavor that sets it apart from the rest.

Furthermore, Costco sells it in packs of four eight-ounce bars for around $19, well below the cost at other retailers, where a single bar can cost up to $6.

Simply Recipes consulted several renowned chefs and recipe developers, who all agreed that this product was their favorite at Costco.

Erin Clarke, author of the blog Well Plated, was clear: “Kerrygold butter is the best of the best.”

Meanwhile, Joanne Gallagher of Inspired Taste added that she always has a stash of this butter in her kitchen. She uses it not only for its flavor, but for the quality of the final result in any recipe.

Kat Marris, recipe developer at Green Chef, explained that this butter elevates sauces by giving them a silky texture and a deeper flavor.

Melanie Gunnell of Mel's Kitchen Cafe swears it's perfect for baking, even when it's only available in a salted version, like at Costco. She simply adjusts the salt in her recipes to balance the flavors.

"I refuse to bake with any other butter," Marris said.

This European-style butter contains less water than conventional American butter, giving it a denser texture and richer flavor. This makes it an excellent choice for everything from cookies and cakes to breads, sauces, pies, and professionally finished savory dishes.

The chefs we surveyed agree that buying this product at Costco is not only a smart decision for its flavor and quality, but also for the savings that come with buying it in bulk. In an environment where food prices continue to rise,having high-end ingredients at an affordable price can make a big difference in any home kitchen.
