Food Pros Say This One Costco Product Is Worth Stocking Up On


Chefs and food experts agree that Costco isn’t just for bulk snacks and family-sized essentials. Hidden among its aisles of everyday goods is one standout product that culinary professionals swear by for its unmatched flavor and value. When four seasoned food pros were asked to share their favorite Costco buy, they all pointed to the same item: a rich, golden staple that has earned permanent space in their kitchens.
Why Culinary Pros Love Costco

Many chefs say Costco has become a go-to source for premium ingredients without the premium price tag. The warehouse retailer offers everything from quality produce to European-style dairy that rivals what’s found in professional kitchens. According to Simply Recipes, even experienced food experts appreciate Costco’s consistency and bulk pricing, which make it easier to cook for large groups or test recipes while keeping costs down without cutting corners on quality or flavor.
The One Product Chefs Can’t Stop Buying

When four culinary professionals were asked to share their favorite Costco find, they all gave the same answer: Kerrygold Pure Irish Butter. This European-style butter is known for its rich, creamy flavor and smooth texture that elevates both simple dishes and complex recipes. It has become a kitchen essential for chefs who value quality ingredients that deliver consistent results, earning its reputation as one of Costco’s most worthwhile staples.
A Butter Known for Its Quality and Flavor

Kerrygold Pure Irish Butter is crafted from the milk of grass-fed cows raised on lush Irish pastures. This natural diet gives the butter its signature golden color and subtly sweet, creamy taste. Unlike many mass-produced options, Kerrygold is churned using traditional methods that preserve its rich texture and flavor. Chefs say that quality difference is noticeable in every bite, whether it is spread on bread or melted into a sauce.
Chef Kat Marris Praises Its Silky Quality

Kat Marris, senior recipe developer at Green Chef, says Kerrygold butter adds a silky, professional finish to sauces and sautés. She uses it for searing, glazing, and creating compound butters that enhance meats and vegetables. Marris explains that its smooth consistency and rich fat content make it easier to build flavor in layers, helping even simple weeknight meals achieve a restaurant-level taste and texture that stand out every time.
How Food Blogger Erin Clarke Uses It

Erin Clarke, author of The Well Plated Cookbook, calls Kerrygold butter her everyday essential for home cooking. She uses it in recipes that highlight its creamy flavor, such as pastas, tarts, and biscuits. Clarke says its smooth texture and golden richness enhance both sweet and savory dishes, adding that it melts beautifully into baked goods and sauces. For her, it is the kind of ingredient that always makes food taste better.
Melanie Gunnell Uses It for Baking

Food blogger and cookbook author Melanie Gunnell says she buys Kerrygold butter from Costco regularly and calls it “amazing for baking.” While Costco carries the salted version, Gunnell notes it still performs beautifully in desserts when the added salt is adjusted. She uses it for cookies, pies, and breads, crediting its smooth texture and rich flavor for creating tender, golden results that elevate homemade treats to a more professional standard.
Why Butter Quality Matters to Chefs

Chefs agree that high-quality butter can completely transform the outcome of a dish. European-style butters like Kerrygold have a higher fat content and lower water percentage, which lead to richer flavors and flakier textures in baked goods. The difference is especially noticeable in pastries, sauces, and spreads, where every ingredient counts. For many culinary professionals, butter quality is the foundation of great cooking, not just a finishing touch.
Premium Butter for Less

Costco offers Kerrygold Pure Irish Butter in boxes of four eight-ounce bars, typically priced around $19 depending on location. At other retailers, a single bar can cost about $6. That makes Costco one of the best places to stock up on premium, grass-fed butter without overspending. For chefs and home cooks alike, the value is hard to beat, especially for an ingredient that delivers consistent quality every time.
Food Experts Agree on This Costco Must-Have

Four culinary professionals — Erin Clarke, Melanie Gunnell, Kat Marris, and Joanne Gallagher — all named Kerrygold as their top Costco pick. Despite their different cooking styles, they praised its taste, versatility, and reliability across recipes. Each chef said the butter consistently performs well in both savory and sweet dishes, making it a dependable ingredient that meets professional standards and offers strong value for its quality.
Why Kerrygold Butter Stands Out Among Costco Finds

With its smooth texture, rich flavor, and affordable bulk pricing, Kerrygold Pure Irish Butter has become a trusted choice among chefs and home cooks. The brand’s grass-fed production and traditional churning methods deliver quality that stands out in any recipe. As Simply Recipes notes, it remains one of Costco’s most consistently praised products, offering shoppers a reliable way to buy premium butter at a reasonable price.
