5 Costco Steaks Shoppers Say Are Best for the Grill

<

Few things define a proper warm-weather gathering like a well-executed steak fresh off a hot grill. Costco has quietly built a serious reputation among home cooks and backyard pitmasters for offering quality cuts at prices that don't require a second mortgage — and for good reason. Their meat department sources from reputable suppliers and turns over inventory quickly, meaning freshness is generally reliable across the board. When it comes to grilling specifically, cut selection matters enormously: thickness, fat marbling, and muscle composition all determine how a steak responds to high heat. Knowing which cuts hold up to direct flame versus those better suited to low-and-slow cooking can mean the difference between a memorable meal and an expensive mistake.

Kirkland Signature Ribeye Cap: The Best Cut at Costco

The spinalis dorsi — the ribeye cap — is widely regarded among butchers and serious grill cooks as the most coveted muscle on the animal, combining the tender texture of a filet with the rich, fatty flavor of a ribeye. Costco's butchers roll, tie, and cut the spinalis into pinwheel-shaped medallions, selling them as USDA Prime boneless ribeye cap steaks, priced around $28 per pound in-store. Reviewers are nearly unanimous: it delivers soft, tender, intense beef flavor with a dark sear on the outside and bright pink meat within. Because the cut carries exceptional natural richness, it needs nothing more than kosher salt and cracked black pepper — no marinade required. Grill over high heat for roughly 8–10 minutes, rest briefly, and you have what many consider the single best steak Costco sells.

Kirkland Signature Prime NY Strip: The Everyday Grill Hero

Costco's USDA Prime New York strip is a consistent crowd-pleaser and a fixture in the warehouse's blue-tray meat case, typically sold in four-packs at around $19.99 per pound. Prime strips from the warehouse show noticeably more marbling than their Choice counterparts, with long, clearly defined muscle fibers that deliver a markedly more tender and luscious bite when grilled to medium-rare. In head-to-head taste tests, the Prime strip's increased fat content translates to genuine, perceptible richness — one reviewer summarized the difference as striking. Each steak comes thick and heavy, often exceeding a pound, making it an outstanding value compared with the $25–$50 per pound typical of other national retailers carrying Prime-grade beef. For the guy who wants a reliable, restaurant-quality slab on the grill without the guesswork of specialty ordering, this is the benchmark cut.

Great Southern Grass Fed Ribeye: Australia's Free-Range Standout

Great Southern sources its beef exclusively from southern Australia, a region prized for lush, year-round pastures where cattle are raised entirely free-range on a pure grass-fed diet, with no added hormones or antibiotics ever used. Every steak is graded under the Meat Standards Australia (MSA) eating quality system — an independent, science-based standard that guarantees a predictable, quality eating experience in the finished product. The ribeyes come in 12-ounce individual packs (14 to a case) and ship frozen, making bulk freezer stocking straightforward for regular grillers. Grass-fed beef from this region is leaner than grain-finished beef with a cleaner, more minerally flavour profile and a firmer bite — qualities that shine under high direct heat on a charcoal or gas grill. With over 700 reviews averaging 4.4 stars on Costco's site, it's a legitimate craft alternative for the conscientious consumer who doesn't want to compromise on grill performance.

Silver Fern Farms Net Carbon Zero Box: New Zealand's Ethical Grill Pack

Silver Fern Farms is one of New Zealand's premier beef cooperatives, and the steak box available through Costco.com delivers a multi-cut selection — ribeye, tenderloin, New York strip, and top sirloin — all sourced from 100% grass-fed, Angus-breed cattle raised with no feedlots, no added hormones, and no antibiotics. Every pound of product in the box carries a certified Net Carbon Zero designation, meaning independently verified emissions from farm to fork are offset by the regenerative vegetation on supplying farms — a meaningful distinction in an era of greenwashing. The steaks are hand-selected by master graders under Silver Fern's proprietary Eating Quality system and aged a minimum of 21 days to develop tenderness and depth of flavour before packaging. New Zealand grass-fed beef typically delivers a cleaner, slightly sweeter finish on the palate compared with American grain-finished cuts, making these a notable conversation piece alongside a great pour of whisky at any backyard grill session. The box holds 4.4 stars from well over 570 Costco reviewers — a strong signal of consistent quality.

Kansas City Steak Co. Ribeye: Aged Heritage, Delivered to Your Door

The Kansas City Steak Company has been a trusted name in premium beef since 1932, and its USDA Choice ribeyes available through Costco's online portal come in 18-ounce cuts — substantial slabs suited for the serious backyard grill master. Each steak is aged up to 28 days, the same aging process the brand applies across its entire lineup, which develops the enzymatic tenderness and concentrated beefy flavour that distinguish dry-aged or wet-aged beef from fresh-cut alternatives. Available in packs of four, eight, or twelve, they're a practical buy for households that grill in volume throughout the season. Grill masters appreciate the consistent sizing and well-trimmed presentation, and the steaks hold their own on a hot grate — developing a proper crust while remaining juicy at medium-rare. At 4.4 stars across nearly 150 Costco ratings, these represent a mainstream brand with genuine craft credentials for the man who wants reliability without sacrificing pedigree.
