Raw lamb heart works well cut into thin strips and quickly seared in a hot pan, or slowly braised until tender. Trim away the tough vessels and membrane first, and make sure the centre is fully cooked before serving.
No, eating raw lamb heart is not considered safe because raw organ meat can carry harmful bacteria or parasites. Cook it thoroughly, and keep its juices and utensils separate from ready-to-eat foods.
Lamb heart has a rich, meaty flavour that is generally milder than liver. Its texture is firm and slightly chewy, so trimming it well and avoiding overcooking help make it more pleasant to eat.
To clean raw lamb heart, cut it open and remove the visible blood clots, tubes, tough outer membrane, and excess fat with a sharp knife. Trimming these parts before cooking improves the texture.
No, soaking lamb heart in milk is not necessary for safety or tenderness. Some cooks use a brief milk soak to soften its flavour, but careful trimming and suitable cooking are usually enough.
Keep raw lamb heart sealed on the lowest refrigerator shelf and cook it within one to two days. Store it away from foods that will be eaten without cooking, so its juices cannot drip onto them.
Yes, raw lamb heart can be frozen. Wrap it airtight to limit freezer burn, thaw it in the refrigerator, and cook it soon after thawing rather than refreezing it raw.
Cook lamb heart to an internal temperature of 160°F (71°C) for food safety. Check the thickest part with a food thermometer, since the outside can brown before the centre is fully cooked.
Lamb heart becomes tough when it is overcooked or cut into thick pieces that cook unevenly. Slice it thinly for a quick sear, or use a slower braise when you want a softer texture.
Lamb heart is a firm, lean muscle with a meat-like flavour, while lamb liver is softer and has a more pronounced, mineral flavour. They need different preparation: heart is typically trimmed of vessels, while liver is sliced and cooked briefly.

Raw lamb heart is the uncooked heart muscle of a lamb, sold as an organ meat. Its texture is firm and lean, with a concentrated, savoury flavour that becomes more pronounced when cooked. It is protein-rich and also provides vitamin B12 and iron.
Lamb heart is eaten in a range of cuisines, often grilled on skewers, pan-fried or added to stews; it is generally cooked rather than served raw. You can pair it with onions, herbs, flatbread or a crisp salad. Keep it chilled before cooking, use clean utensils, and cook it thoroughly instead of tasting it raw. For a lighter meal, cook it with little added fat and serve alongside vegetables.
Very high
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
