Steller sea lion heart is a dense, iron-rich organ meat prized in Alaska Native cuisine, offering a surprisingly mild, clean flavor with a firm, smooth texture akin to lean beef heart. Its nutritional profile is exceptionally lean, packing a high-protein punch with minimal fat and carbohydrates. This makes it a potent source of essential nutrients like vitamin B12 and iron in a very low-calorie package.

↓ Full nutritionIt is deeply valued for its clean, mineral-rich taste and its cultural significance as a traditional, nutrient-dense food source. Its firm texture holds up well to various preparation methods, from grilling to stewing.
As an organ meat, it can be high in cholesterol and purines, which may be a concern for individuals with gout or specific heart conditions. To mitigate, practice strict portion control (a few ounces at a time) and balance it with fiber-rich vegetables like berries or leafy greens to aid digestion.
The heart of a Steller sea lion can weigh over 11 kilograms (25 pounds), making it one of the largest hearts of any marine mammal and a massive single-serving organ.

How does sea lion heart taste compared to beef heart?
Sea lion heart is often described as milder and cleaner-tasting than beef heart, with a less pronounced 'gamey' or mineral flavor. Its texture is similarly dense and smooth but can be slightly firmer.
Is it safe to eat raw?
In traditional Alaska Native preparations, it is sometimes consumed raw or fermented. However, as with any wild game, there are risks of parasites or bacteria. Modern safety guidelines recommend thorough cooking to an internal temperature of at least 160°F (71°C).
Why is it so lean?
Heart is a constantly working muscle, so it is composed primarily of lean muscle tissue and connective tissue, with very little intramuscular fat marbling, resulting in its exceptionally low fat content.
