Overview of Bison Spleen

Bison spleen, also known as buffalo spleen, is an organ found in the abdominal cavity of bison. The spleen plays a vital role in the immune system by filtering out old and damaged red blood cells, as well as storing white blood cells to fight off infections. In some cultures, bison spleen has been traditionally used for medicinal purposes due to its high nutrient content.

Bison spleen is a large organ, typically weighing between 1-3 pounds in adult bison. It is located towards the back of the abdominal cavity and is connected to the stomach and intestines through several blood vessels. The spleen receives a rich blood supply, making it an important organ for filtering out impurities from the blood.

In terms of appearance, bison spleen is oblong in shape with a deep red color. It has a smooth outer surface and is covered by a thin layer of connective tissue called the capsule. The inner surface of the capsule has indentations that contain lymphoid tissue, which plays a crucial role in immune function.

Nutritional Benefits

Bison spleen has long been revered for its high nutritional value. It is a great source of iron, protein, and essential vitamins and minerals such as vitamin B12 and folate. A 3-ounce serving of cooked bison spleen provides approximately 7 grams of protein and 5% of the recommended daily intake (RDI) for iron.

In addition to these essential nutrients, bison spleen also contains trace amounts of other minerals including zinc, selenium, magnesium, potassium, and phosphorus. These nutrients are important for maintaining overall health and can help prevent deficiencies that may lead to various health issues.

Preparing Bison Spleen

When preparing bison spleen for cooking, it is important to thoroughly clean and trim the organ. Rinse the spleen under cold water and use a sharp knife to remove any excess connective tissue or fat. Once cleaned, the spleen can be cut into smaller pieces depending on the recipe being used.

Bison spleen can be prepared in a variety of ways, including sautéing, grilling, or slow cooking. It is often recommended to marinate the spleen beforehand to enhance its flavor and tenderness. Some popular marinade options include herbs, garlic, ginger, soy sauce, or vinegar.

Cooking Tips

When cooking bison spleen, it is important to keep in mind that it can become tough if overcooked. This is why many recipes suggest marinating and slow cooking methods to keep the meat moist and tender. Avoid cooking bison spleen at high temperatures as this can also make it tough.

One way to ensure tenderness when cooking bison spleen is to use a meat mallet or tenderizer tool before cooking. This will help break down the muscle fibers and make it easier to chew.

Recipe Ideas

Here are a few simple recipe ideas to help you get started with cooking bison spleen:

1) Sautéed Bison Spleen: In a pan over medium heat, add sliced bison spleen with your choice of marinade or seasoning (such as garlic powder, salt, and pepper). Cook for 5-7 minutes until fully cooked and slightly crispy.

2) Grilled Bison Spleen Skewers: Cut bison spleen into small cubes and marinate in your choice of marinade for at least 30 minutes. Skewer the pieces onto wooden or metal skewers and grill for about 10 minutes on each side until fully cooked.

3) Slow Cooked Bison Spleen Stew: Cut bison spleen into bite-sized pieces and add to a slow cooker with vegetables, seasonings, and broth. Cook on low for 6-8 hours or on high for 3-4 hours until the spleen is tender.


While bison spleen is a nutritious and delicious ingredient to add to your diet, it’s important to note that it may not be suitable for everyone. People with certain health conditions, such as iron overload disorders or autoimmune diseases, should consult their healthcare provider before consuming bison spleen.

Additionally, it is important to source bison spleen from reputable and trusted sources to ensure it is safe for consumption. Carefully handle and cook the organ to avoid any potential foodborne illnesses.

5 Health Benefits of Cooking Bison Spleen

Bison spleen may not be the most common ingredient in the kitchen, but it definitely has a lot to offer when it comes to health benefits. Here are five reasons why you should consider cooking and incorporating bison spleen into your diet:

1. Rich in Essential Nutrients
Bison spleen is packed with essential nutrients that are vital for overall health and wellbeing. It is a great source of protein, iron, zinc, and B vitamins such as vitamin B12 and folate. These nutrients play important roles in functions such as metabolism, immune system maintenance, and red blood cell production.

2. Boosts Immune System
The spleen is a key organ in the immune system, responsible for removing old or damaged red blood cells from circulation and fighting off infections. The consumption of bison spleen can help strengthen your immune system due to its high concentration of specialized cells called macrophages, which play a crucial role in defending the body against disease-causing organisms.

3. Supports Optimal Brain Function
Bison spleen contains a good amount of vitamin B12, which is essential for optimal brain function. This vitamin is involved in the production of neurotransmitters, which are chemical messengers that transmit signals between nerve cells. A deficiency in vitamin B12 can lead to symptoms like fatigue, memory loss, and mood disturbances.

4. Powerful Antioxidant Activity
Antioxidants help protect our bodies from cell damage caused by harmful molecules known as free radicals. Bison spleen contains high levels of antioxidants that can neutralize free radicals and prevent oxidative stress that contributes to chronic diseases such as cancer.

5. Promotes Healthy Blood Circulation
Iron is an important mineral required for healthy blood circulation and oxygen transport throughout the body. Those who are deficient in iron may experience symptoms like fatigue and weakness due to inadequate oxygen supply to their tissues. Bison spleen is an excellent source of iron and can help prevent iron-deficiency anemia.

Incorporating bison spleen into your diet, whether grilled, sautéed, or stewed, can provide you with numerous health benefits. Its nutrient-dense nature makes it a great addition to any meal and can help promote overall health and wellbeing.
