It’s no secret: Costco is a favorite stop for professional chefs and food lovers across the country. The bulk retailer is a treasure trove of pantry staples and hidden gems — including a well-stocked cheese case. All that abundance can be overwhelming, though.

“I would approach shopping at bulk retailers the same way you would with other grocery stores —  stocking up on everyday essentials that are used frequently and purchasing more specialty items for larger gatherings,” says certified cheese professional Kyra James. “Cheeses like Parmigiano Reggiano and Pecorino Romano may be used more often and therefore are worth regularly picking up in bulk.”

We tapped James and two other experts to share their favorite Costco cheeses, from classics to lesser-known picks.

Costco’s take on a classic Parmigiano Reggiano, aged for 24 or 36 months, is a no-brainer for “Cheese Sex Death” author and former cheesemonger Erika Kubick. It’s available in one-pound wedges — but she reassures us that this this “go-to” cheese is versatile and crowd-pleasing enough to work through quickly. James seconds this pick, noting its high quality at an affordable price point. Try it shaved over grilled vegetables for a brilliant summer dinner.
