Kirkland Signature Fresh Steelhead Fillet is a farm-raised, boneless, skin-on fillet sold by the pound. Steelhead trout (Oncorhynchus mykiss) is the anadromous form of rainbow trout, prized for its vibrant pink-orange flesh, mild flavor, and rich, flaky texture that closely resembles Atlantic salmon. Costco sources this steelhead from farm-raised operations and sells it fresh, never frozen, providing consistent quality and availability year-round.

The fillet is skin-on and boneless, making it easy to prepare with minimal effort in the kitchen. Steelhead is highly versatile and well-suited for pan-searing, grilling, baking, poaching, broiling, or cedar plank cooking. It pairs well with lemon, herbs, capers, dill, and simple butter sauces. Its rich fat content makes it forgiving to cook, staying moist even with high heat.

Steelhead trout is an excellent source of omega-3 fatty acids, high-quality protein, vitamin B12, vitamin D, and selenium. It provides a nutritional profile comparable to Atlantic salmon at a typically lower price point, making it one of the best value seafood options at Costco.
