Premium American Wagyu beef inside skirt steaks, priced per pound and sold in Costco's fresh meat department. American Wagyu is a cross between Japanese Wagyu cattle and American Black Angus, producing beef with exceptional marbling, tenderness, and rich umami flavor. Skirt steak is a flavorful, long flat cut from the plate section of the cow, known for its distinctive grain and deep beef taste.

This American Wagyu offers significantly more marbling than conventional USDA Choice or Prime beef, resulting in enhanced tenderness and juiciness. The inside skirt (also called inside diaphragm) is typically more tender than outside skirt and works exceptionally well for grilling, searing over high heat, fajitas, stir-fry, and carne asada. For best results, cook to medium-rare or medium and slice against the grain to maximize tenderness. Many Costco locations carry Imperial American Wagyu beef, which is raised in the United States and represents a more affordable alternative to imported Japanese A5 Wagyu while maintaining superior quality compared to standard beef.
