A lot of people think that eating an animal’s liver is like eating the filter out of a car, to quote Dick Gregory. If the liver is the main filter in the body, then it must hold all the toxins it removes from the blood, right? Wrong. All the toxic compounds that the liver removes from the bloodstream are broken down into less-harmful molecules. Those molecules then enter blood or bile. Toxins in the blood are cleaned out by the kidneys and leave the body through urine. Toxins in bile leave the body through the digestive system as feces. It is safe to eat and may be one of the most nutrient-dense foods in the world because it doesn’t store toxic waste.
What the liver does hold on to are vitamins and minerals. Those nutrients are pulled from the blood during filtration and stored for distribution to other organs. A few ounces of liver contains the recommended daily amount of vitamin B12, vitamin A, riboflavin, and copper. It also has a lot of minerals and vitamins that are hard to find in other foods, like iron, phosphorus, selenium, zinc, and selenium. According to new information, the daily recommended amounts of vitamins and nutrients may be much lower than what the body really needs. Researchers have found a link between diets from around the world, especially those of people who are farther away from the global industrial food system, and very high levels of all vitamins and minerals and good health and a low rate of all diseases. Liver and organ meats are often staples of such diets, providing a concentrated source of nourishment.
Beef liver is a nutritional powerhouse, densely packed with protein, vitamins, and minerals. However, it needs to be cleaned and cooked properly to enjoy the full benefits and delicious flavor. A key step is deveining – removing the thin membrane surrounding the liver. With practice, deveining is quick and significantly improves the taste and mouthfeel of seared, sauteed, or blended liver recipes. This guide covers why deveining matters and walks through the easy process step-by-step.
Why Bother Deveining Liver?
The liver from cattle and other animals is covered by a thin, milky-colored membrane. This membrane assists with structure and blood flow when the liver is functioning within a live animal. For culinary purposes, removing this membrane prior to cooking improves liver in several ways:
-
Enhances texture – Deveining makes the liver smoother and more tender when cooked.
-
Intensifies flavor – Removing the membrane allows seasonings and sauces to penetrate and coat the liver rather than sit on top
-
Improves appearance – Deveined liver sears and cooks more evenly, without the wrinkled membrane.
-
Eases eating – The slippery membrane can make liver harder to chew and less palatable
While not absolutely necessary, taking the couple extra minutes to devein really maximizes the liver’s flavor and quality.
When to Devein Liver
For whole beef liver, it’s easiest to devein immediately after removal and before cutting into portions. However, membrane can be removed from sliced liver as well. Key times to devein:
-
After harvesting liver from a carcass, before freezing or refrigerating.
-
Right before prepping and cooking fresh liver.
-
When thawing previously frozen liver to use.
-
Before grinding liver for sausage or paté recipes.
Deveining is quick and simple enough to do on-the-spot before cooking. However, it can also be done in batches whenever working with fresh liver.
Step-by-Step Guide to Deveining Liver
Deveining only takes about 2-3 minutes for a whole liver. Follow these simple steps:
1. Place Liver Membrane-Side Up
Lay the cleaned, raw liver on a cutting board or flat work surface. Position it so the semi-transparent membrane layer faces upwards.
2. Start Peeling at One Edge
Use your fingers to loosen a half-inch corner section of the membrane from the liver tissue underneath.
3. Grab and Slowly Tear Membrane Away
Once lifted, take hold of the peeled membrane edge and slowly pull it up and away from the liver. Tear upwards with steady, even pressure.
4. Keep Pulling Until Entire Membrane Lifts Off
Continue gripping and tearing the membrane from the liver. Work carefully to remove it in one whole piece if possible.
5. Inspect Liver and Remove Any Remaining Membrane
After removing the main membrane sheet, inspect the liver for any remaining wispy pieces. Use a paring knife to trim these pieces away.
6. Rinse Liver Before Cutting or Cooking
Once deveined, give the liver a quick rinse or soak to remove any blood or residue. Pat dry and proceed with recipes as desired.
Tips for Effortless, Effective Deveining
Use these tips and tricks for flawless liver membrane removal every time:
-
Start deveining liver when very fresh. Membrane adheres more stubbornly later.
-
Work slowly and evenly to peel in one intact sheet if possible.
-
Trim veins and ducts before deveining to avoid tearing.
-
Keep the liver secured and stationary as you pull. Don’t rip your deveined progress!
-
Use a sharp paring knife to cleanly trim any stubborn bits.
-
Rinse after deveining to prepare for cooking. Pat dry thoroughly.
-
Chilling liver slightly firms the membrane for easier removal.
-
Consider wearing gloves, especially with multiple livers. The membrane is quite slippery.
Storing Deveined Liver for Later Use
Once deveined, liver holds best in the refrigerator for 2-3 days. For longer storage, deveined liver can be frozen for 4-6 months. Here are some storage tips:
-
Separate liver into meal-sized portions before bagging.
-
Exclude air by pressing out before sealing freezer bags.
-
Label bags with date and quantity for easy identification.
-
For max freshness, use refrigerated liver within 2 days, frozen within 4 months.
-
Defrost frozen liver overnight in fridge before cooking. Don’t microwave.
Proper storage keeps deveined liver in prime condition until you’re ready to cook and enjoy!

Harvesting and Cleaning Liver
The liver is on the right side of the abdomen in all animals. It is attached to the diaphragm near the spine. When gutting an animal, all the digestive organs can be removed, leaving only the liver attached. You can remove it with knife or hand; it should easily come out with a few deliberate tugs. When you tear the liver, you won’t hurt it, but you will lose valuable pieces of the organ.
All monogastric animals (like pigs, bears, and humans) and almost all ruminants (like cows, sheep, goats, elk, and pronghorn) have gallbladders that make bile. Cervids, on the other hand, like deer and moose, do not. This means that when you pull out a liver from a whitetail or mule deer, you won’t have to worry about popping the small green bag that is attached to the livers of most other animals (horses, mice, pigeons, and lampreys don’t have gallbladders). When cutting a beautiful, shiny liver from an elk, pronghorn, sheep, or cow, you must be very careful to remove the gallbladder. You can cut under it or put your fingers under the small tube that connects the bladder to the duct and gently pull on the connective membrane. This method takes some practice.
To assess liver quality, check first for any significant scarring. Scars will look like starbursts or spiderwebs. The presence of scarring can occur from cysts, abscesses, or flukes, indicating a past or current infection. Large scars usually render the meat inedible, but more negligible scarring shouldn’t affect the taste or condition. A perfect liver will have no scars. Cut into some of the bile ducts and veins and look for small worms or pus to see if there are cysts, flukes (tiny parasites that live in the ducts), or infections. Discard the liver if you find anything other than blood.
To trim the liver for cooking, cut off all connective tissue and any large veins or ducts. The veins will hold on to blood, which can cause many of the unpleasant tastes that people usually associate with the liver. The thin membrane on the liver can be pulled off if desired. Taking off the membrane will make it easier to cut and cook, but you don’t need to do that if you want to grind or blend it.
Soaking liver in milk or saltwater can pull out any leftover blood and improve the flavor. I usually cut the liver into cubes or strips, put them in ziplock bags with milk, and then freeze each one. This method has proven to be much more manageable and effective than attempting to soak an entire liver.
Liver can be eaten fresh, seared quickly in a cast iron pan, and left rare in the middle. The taste of overcooked liver often discourages people from eating it again. Putting liver on my burger every week is one of my favorite ways to eat it (and get other people to do the same). You can also grind up other organs, like the heart, with liver, meat, and fat to make a quick and healthy meal.
Any liver I could get my hands on—goat, deer, pork, elk, beef, chicken—I would turn into pate. Any kind of liver can be cooked briefly with garlic, onions, salt, and spices, then mixed with butter and cognac to make a smooth paste that can be spread on a big piece of sourdough bread. With a few pickled red onions on top, you have the perfect meal. “Is life worth living? It all depends on the liver,” said William James, an American philosopher who lived in the 1800s. ”.
