Organ Meats Guide — Benefits, Cooking and Recipes

Organ meats were a dietary staple for generations — prized for their nutritional density and their role in nose-to-tail cooking. Modern diets largely abandoned them in favor of muscle cuts. That shift came at a nutritional cost. Three ounces of beef liver delivers more than 3,000% of the daily vitamin B12 requirement and over 800% of the daily vitamin A requirement. No supplement comes close to that in bioavailable form.

This guide covers the most commonly available organ meats — what each one offers nutritionally, how to cook it, and why the source matters as much as the cut.

Key Takeaways

• Organ meats are among the most nutrient-dense foods available — 3 oz of beef liver contains over 3,000% of daily B12 and 800% of daily vitamin A
• Nose-to-tail eating reduces waste, honors the entire animal, and supports regenerative agriculture
• Grass-fed organ meats carry higher levels of omega-3s, CLA, and fat-soluble vitamins than grain-fed equivalents
• Most nutritionists recommend 3–6 ounces of organ meats once or twice per week
• Beef heart is the best starting point for beginners — mild flavor, familiar texture, versatile cooking options

What Are Organ Meats?

Organ meats — sometimes called offal — are the edible internal organs and non-muscle cuts of an animal. This includes liver, heart, kidneys, tongue, sweetbreads, and marrow bones. In many of the world's great food traditions — French, Italian, Mexican, Middle Eastern — these cuts are considered delicacies, not afterthoughts.

In the United States, organ meats fell out of mainstream cooking over the last several decades as the food system shifted toward boneless, skinless, easily processed muscle cuts. That shift made food more convenient and less nutritious at the same time. Nose-to-tail eating — using the whole animal rather than just the premium cuts — is a direct response to that tradeoff. It is also how every traditional food culture ate before industrialization made selective processing economically viable.

Why Organ Meats Deserve a Place on Your Plate

Modern diets favor muscle meat, but organ meats are consistently richer in vitamins, minerals, and unique compounds than any steak or roast. The Cleveland Clinic notes that organ meats are particularly high in iron, zinc, and vitamin B12 — nutrients essential for energy, brain function, and immune health.

According to a 2023 NIH review, just 3 ounces of beef liver can contain more than 3,000% of the daily vitamin B12 requirement, over 800% of the daily vitamin A requirement, and nearly the entire daily copper requirement. That concentration of nutrition in a small serving is what makes organ meats genuinely different from muscle cuts — not just marginally better, but categorically more dense.

The key distinction is bioavailability. Nutrients in organ meats are more readily absorbed than those in most plant sources or supplements, meaning your body actually uses what it takes in. For anyone eating a nutrient-dense, whole-food diet, organ meats are one of the most efficient ways to fill nutritional gaps that muscle meat alone cannot address. For more on how sourcing affects nutritional quality, our grass-fed vs. grass-finished guide covers why the animal's diet directly affects the nutritional profile of every cut.

Types of Organ Meats and Their Benefits

Liver

Liver is the most nutritionally significant organ meat available. It is loaded with vitamin A, vitamin B12, folate, iron, and high-quality complete protein. A single serving delivers more nutrition than most multivitamins — in a natural, bioavailable form the body can use immediately rather than a synthetic isolate it has to process. Grass-fed beef liver carries higher levels of omega-3 fatty acids and fat-soluble vitamins than grain-fed liver, making the sourcing decision directly relevant to the nutritional outcome.

Heart

Beef heart is the best starting point for anyone new to organ meats. It is technically a muscle organ, which gives it a texture and flavor profile closer to a lean steak than to liver or kidney. It is rich in CoQ10, an antioxidant compound that supports cardiovascular health and cellular energy production. Beef heart is also lean, versatile, and responds well to grilling, braising, or slow cooking. If you have avoided organ meats because of strong flavor concerns, heart is the place to start.

Kidneys

Kidneys are rich in vitamin B12, riboflavin, and selenium — a mineral critical for thyroid function and antioxidant defense. When properly prepared, they have a mild flavor and tender texture. Soaking kidneys in cold water or milk for 30–60 minutes before cooking reduces any strong flavor significantly. Many professional chefs consider properly prepared kidneys one of the more underrated organ meats available.

Bone Marrow

Bone marrow delivers healthy fats, collagen, and key minerals including phosphorus and calcium. It is a staple in classic preparations like roasted marrow bones and ossobuco, and one of the simplest organ preparations to execute at home. For a full step-by-step guide on how to prepare, cook, and serve bone marrow, see our bone marrow cooking guide.

Beef Shank

Beef shank is a cross-cut portion of the leg that contains marrow and significant connective tissue. Long, slow braising breaks that connective tissue down into gelatin, producing a rich, deeply flavored broth and fall-off-the-bone meat with joint-supporting compounds. It is one of the most forgiving cuts to cook — the longer it goes, the better it gets.

How to Cook Organ Meats — Tips for Success

Source quality first. The difference between grass-fed and grain-fed organ meats is more pronounced than with muscle cuts, because organ meats concentrate whatever the animal was exposed to — including hormones, antibiotics, and the fat-soluble vitamins that accumulate from a grass diet. Start with grass-fed, pasture-raised organ meats from a source you can verify.

Use them fresh or freeze immediately. Organ meats are more perishable than muscle cuts. If you are not cooking within 1–2 days of receipt, freeze immediately in airtight, vacuum-sealed packaging.

Soak when appropriate. Soaking liver or kidneys in cold salted water or milk for 30–60 minutes before cooking mellows strong flavors without affecting nutritional content. This step is optional for heart and not applicable to marrow bones.

Match the cooking method to the cut. Liver and heart respond to high-heat, quick searing — 1–3 minutes per side. Tongue, shank, and other connective-tissue-rich cuts need low and slow braising, typically 3–4 hours at 325°F. Marrow bones roast at high heat (425–450°F) for 15–20 minutes.

Use a thermometer. Liver and heart should reach an internal temperature of 160°F. Tongue should be fork-tender at 195°F or above. Marrow is done when it pulls slightly from the bone walls and jiggles gently.

Health Benefits of Organ Meats

Organ meats are nutrient-dense enough that small, regular portions — 3–6 ounces once or twice a week — deliver meaningful nutritional impact. This fits naturally into a grass-fed beef-centered diet that prioritizes quality and nutritional density over volume.

Drawing from Cleveland Clinic and NIH research, the primary benefits are:

High bioavailable nutrition. Nutrients in organ meats are more readily absorbed than those in most plant sources or synthetic supplements. The body uses what it takes in rather than processing isolates it was not designed to metabolize.

Energy production support. Rich in iron, B vitamins, and CoQ10 — compounds that directly support cellular energy metabolism and help address fatigue at its nutritional root rather than masking it.

Brain and neurological health. High B12 and choline levels in liver and heart support cognitive function, memory, and neurological integrity — nutrients that are chronically under-consumed in most modern diets.

Joint and connective tissue support. Collagen and glycine from cuts like shank and marrow support connective tissues, joint health, and skin elasticity in ways that muscle meat alone does not provide.

Whole-animal utilization. Eating organ meats reduces waste, supports the economics of regenerative ranching, and honors the full value of the animal. A rancher raising 100% grass-fed beef produces organ meats alongside every muscle cut. Buying them supports that entire operation.

Organ Meats in Global Cuisine

Nose-to-tail eating is not a trend — it is the historical baseline. Every major food culture used the whole animal before industrialization made selective processing economically dominant.

In France, pâté and foie gras elevate liver to gourmet status. In Mexico, tacos de lengua — beef tongue — are street food staples eaten daily by millions. Italian ossobuco showcases beef shank braised with vegetables, wine, and stock until fall-off-the-bone tender. Spanish cocido madrileño features beef offal in a hearty one-pot meal that has fed families for centuries. Scottish haggis, Peruvian anticuchos, Filipino dinuguan — organ meats appear in virtually every traditional cuisine in the world because they were the most nutritious, most available, and most economical cuts on the animal.

The American abandonment of organ meats is the historical anomaly. The rest of the world never stopped eating them.

Organ Meat Recipes to Try at Home

Pan-Seared Grass-Fed Beef Liver with Caramelized Onions

Ingredients: 1 lb grass-fed beef liver sliced 1/2-inch thick, 2 tbsp butter, 3 large onions sliced thin, salt, pepper, fresh parsley, lemon.

Method: Caramelize onions in butter over low heat for 20–25 minutes until deeply golden. Season liver with salt and pepper, then sear in a hot cast-iron skillet for 2–3 minutes per side until just cooked through — do not overcook, liver toughens quickly. Serve over the onions with a squeeze of fresh lemon and a scatter of parsley.

Slow-Braised Beef Shank with Red Wine

Ingredients: 2–3 lb grass-fed beef shank, 1 bottle dry red wine, 4 cups beef stock, carrots, celery, garlic, bay leaves, thyme, salt, pepper.

Method: Brown shank pieces in a Dutch oven over high heat, then set aside. Sauté carrots, celery, and garlic in the same pot, deglaze with wine, return shank to pot, add stock and herbs. Cover and braise at 325°F for 3–4 hours until fork tender. Serve with crusty bread to absorb the braising liquid.

Roasted Bone Marrow with Sea Salt and Parsley

Ingredients: 4 grass-fed split marrow bones, coarse sea salt, fresh flat-leaf parsley, toasted sourdough.

Method: Soak bones in salted cold water for 12–24 hours. Pat dry, place cut-side up on a baking sheet, season with salt. Roast at 450°F for 15–20 minutes until the marrow pulls from the bone walls and has a golden surface. Scoop onto toasted bread, finish with flaky salt and parsley. For the full method with troubleshooting tips, see our complete bone marrow cooking guide.

Storing and Freezing Organ Meats

Refrigerate fresh organ meats at 32–34°F and use within 1–2 days of purchase or thawing. Organ meats are more perishable than muscle cuts and should not sit in the refrigerator for extended periods.

Freeze in airtight, vacuum-sealed packaging for up to 3 months. Label packages with the cut type and freeze date. Ferguson Farms organ meats ship frozen and vacuum-sealed — move them directly to your freezer on arrival if you are not cooking within 48 hours.

Thaw in the refrigerator overnight. Never thaw organ meats at room temperature, which creates conditions for bacterial growth. Cold water thawing in a sealed bag is an acceptable faster alternative when refrigerator thawing time is not available.

Where to Buy Quality Organ Meats

Quality organ meats are available from local butchers, farmers markets, and direct-to-consumer sources. The most important factor is sourcing: grass-fed, pasture-raised organ meats from animals raised without added hormones or antibiotics are meaningfully different from conventional organ meats in both nutritional profile and flavor.

Ferguson Farms carries 100% grass-fed beef organ meats — liver, heart, kidney, marrow bones, and more — sourced from trusted ranch partners in Central Florida and shipped frozen nationwide. Every product is raised without added hormones, antibiotics, or GMOs. For a full picture of our sourcing standards, visit our sourcing protocols page.

Frequently Asked Questions About Organ Meats

What are organ meats and why should I eat them?

Organ meats are the edible internal organs of an animal — liver, heart, kidney, tongue, marrow, and others. They are among the most nutrient-dense foods available, delivering concentrated amounts of vitamin B12, vitamin A, iron, CoQ10, and other compounds in bioavailable form that muscle cuts do not provide at the same density. A small serving once or twice a week significantly expands the nutritional range of a meat-based diet.

Which organ meat should I try first?

Beef heart is the best entry point. It has a texture and flavor closer to lean steak than to liver or kidney — mild, firm, and familiar enough that most people who are cautious about organ meats find it approachable. Once comfortable with heart, beef liver delivers the highest nutritional payoff of any organ meat.

How often should I eat organ meats?

Most nutritionists recommend 3–6 ounces once or twice per week. Organ meats are nutrient-dense enough that small, regular portions deliver meaningful benefit. Daily consumption of liver in large quantities is not recommended due to the very high vitamin A content, which can accumulate at high doses.

Do grass-fed organ meats taste different from conventional?

Yes, meaningfully so. Grass-fed organ meats have a cleaner, more mineral-forward flavor than grain-fed equivalents. The fat composition is also different — higher in omega-3s and CLA — which affects both flavor and nutritional profile. The difference is more pronounced in organ meats than in muscle cuts because organs concentrate the fat-soluble compounds from the animal's diet.

How do I reduce the strong flavor of liver or kidney?

Soak in cold salted water or milk for 30–60 minutes before cooking. This draws out compounds that contribute to strong flavor without affecting the nutritional content. Drain, rinse, and pat dry before cooking. Pairing with caramelized onions, fresh parsley, or a squeeze of lemon at serving also cuts the richness significantly.

Are organ meats safe to eat?

Yes, when properly sourced and cooked. Cook liver and heart to an internal temperature of 160°F. Source from grass-fed, pasture-raised animals raised without antibiotics or added hormones — this matters more for organ meats than for muscle cuts because organs are the body's processing centers and reflect the animal's diet and environment more directly. If you have specific health conditions, consult a healthcare provider before significantly increasing organ meat consumption.
