Seattle – September 22, 2026 -- A whitefish sold in the freezer aisle of most major grocery stores is drawing new attention as a whole-food protein source, delivering 26 grams of complete protein per 3.5-ounce serving. Wild Alaska Sole, often labeled Wild Alaska Flounder in the U.S., comes from Alaskan waters and contains all nine essential amino acids the body cannot produce on its own.
The fish arrives as shoppers increasingly scrutinize where their protein comes from, not just how much of it they're eating. Many high-protein products on store shelves rely on soy or vegetable isolates, while Wild Alaska Sole offers protein in its natural, unprocessed form.
One serving delivers 104 calories and a dense nutrient profile
A 3.5-ounce serving contains 665 mg of omega-3s (EPA and DHA) for brain, heart and eye health, along with 11 mcg of vitamin B-12, 32 mcg of selenium, 300 mg of potassium and 212 mg of phosphorus. At 104 calories, the fish provides more protein per calorie than chicken or beef, according to the Wild Alaska Sole Association.
Pat Shanahan says the fish has been overlooked in freezer aisles for years
"Twenty-six grams of complete protein, all nine essential amino acids, and nothing processed along the way," said Pat Shanahan, executive director of the Wild Alaska Sole Association. He said most shoppers have never heard of the fish despite its long-standing availability, and the association wants to close that awareness gap.
Fillets cook in 3 to 7 minutes, even from frozen
The thin fillets thaw quickly and can be pan-seared, baked, poached, steamed or air-fried without prior thawing. Wild Alaska Sole is widely stocked in the freezer sections of major grocery chains nationwide.
