What Is Offal? Types, Nutrition, Benefits, & Uses

Offal Definition & Meaning

What do liver, heart, intestines, tongue, and every strange-smelling meat your father would jokingly try to get to you eat when you were younger have in common?

They’re all offal.

Often overlooked in American cuisine, offal is finally starting to catch on, and for good reason; offal offers a rich world of flavors, textures, and nutrients. All you have to do is give it a shot!

What is offal?

Offal is a catch-all term for internal organs and entrails. It literally means “off all”, or things that have fallen off while butchering, and “waste” in German, although it in no way deserves that label because offal is incredibly tasty.

Also referred to as “variety meats”, offal can be everything from liver to bone marrow, to tripe, to heart, and it’s not animal-specific. You can attach offal to the animal you’re referring to, like beef offal or pork offal.

Outside of a culinary context, it can mean anything in the animal that isn’t going to be used for animal or human consumption.

Offal has a rich culinary history, dating back to our time as prized meats in hunter-gatherer societies [*]. While America has been reluctant to adopt offal to the same effect as some other countries, there are still a variety of dishes that utilize offal in America, and each year it seems to increase in popularity.

Some more familiar offal for Americans include calf livers and beef tongue, but opening up yourself to the world of offal includes an amazing array of international delicacies, including [*]:

  • Peru’s anticuchos – These are delicious skewers of marinated beef heart.
  • Argentina’s parrilladas – Famous for their beef, Argentina commonly prepares entire assortments of prepared offal.
  • The French foie gras – Famous in high-end restaurants, the buttery richness of duck liver is internationally renowned.
  • German leberklosse – These beef liver dumplings are a German passion.
  • Tripe and lengua tacos from Mexico – Tripe and tongue tacos are very popular in Mexican cuisine. Try a lengua taco next time you go to a stand!
  • Russia’s kholodets – Essentially Russian head cheese, this dish is made from boiled pig’s head and feet and utilizes the gelatin found in offal to create a spread.

Besides the culinary adventurism offal provides, organ meats have a lot of nutritional value.

Offal nutrition facts

While there are small variations in nutrition across the different animals and organs, most offal is highly nutritious and more densely packed with nutrients on a per-calorie basis than muscle meats.

Along with being a high protein source with plenty of essential amino acids, offal offers high amounts of folate, vitamin B12, iron, magnesium, selenium, zinc, and fat-soluble vitamins A, D, E, and K [*].

The upsides of offal

Offers lots of iron

You may be surprised to hear that iron is the most common nutritional deficiency in the U.S. Iron helps create hemoglobin, which is the substance that carries oxygen from your lungs to the rest of your body. Getting the right amount of iron can help you feel less fatigued, and offal is a great source of this essential mineral [*].

High protein keeps you full

Offal has a lot of protein per gram, so even though it’s typical to eat smaller portions of offal compared to other cuts, you still get plenty of stomach-filling proteins. This helps you stay full longer and snack less.

Contains choline which promotes brain health

Choline is another essential nutrient offered by offal. It helps liver function, healthy brain development, muscle movement, your nervous system, and metabolism, and most people don’t get enough of this nutrient either [*].

Offal is often a cost-effective option

Since offal isn’t in high demand by average American consumers, butchers often discard pieces of offal that are perfectly good (and delicious) to eat. Chances are the butchers and meat providers will sell offal at a price lower than your standard cuts.

Environmentally friendly

For similar reasons that the price of offal can be lower, you can also impact the environment by helping use more of each cow. The more we can eat from a single cow, the less we discard.

Potential downsides of offal

Requires caution when pregnant

Offal is extremely high in Vitamin A, which can contribute to birth defects in pregnant women when eaten in high quantities [*].

Is high in cholesterol

Most offal has a high amount of cholesterol, but keep in mind that eating foods high in cholesterol is not directly linked to higher blood cholesterol or heart disease risk [*].

Can be problematic for gout sufferers

Purine is linked to gout inflammation, and offal carries this compound. If you suffer from gout, you should avoid eating offal and other foods that contain purine [*].

Tends to spoil faster than other meats

Offal isn’t great for long-term storage because it goes bad faster than traditional cuts. Make sure to buy fresh from a respected meat provider or butcher and plan to eat the offal as soon as possible.

How to add offal to your diet

Getting started with offal meat is easy and absolutely worth it. You have lots of options to choose from in the world of offal, but whatever you choose, make sure you buy grass-fed offal.

Why? Offal or organ meats from grass-fed animals are chock full of nutrients, and that is a direct effect stemming from the diet and conditions in which they were raised in. Animals subjected to unnatural diets, drugs, and poor living conditions affect the health of their organs, which in turn affects their flavor and nutrient profiles [*].

At US Wellness Meats, we incorporate a 30 to 45-day rest period between grazing and increase the density of existing plants in our grass-fed cattle pastures while allowing for the re-introduction of new native plants.

As a result, all of our grass-fed cows are eating the most natural food and are treated with the utmost care. This devotion to sustainable and humane practices is exactly why our meat is so delicious and enriching.

Get started with these types of offal

A common complaint of offal is the distinctive flavor that accompanies it, much like seafood. While this is present across all offal, the ways in which you cook it, and the types of offal you choose can dramatically affect how pronounced it is.

We recommend starting with the types of offal below — think of them as your gateway to a whole new culinary world!


Sweetbreads, deliciously rich cuts of the thymus gland, are typically fried, served like gourmet chicken bites, and are a great way to experience offal.

Head cheese

Head cheese is an odd name, but don’t look past this pâté cousin. Head cheese is made from the bits left behind in the head after the brain and other organs have been removed, and the high gelatin content cooks down into a delicious spread.

Bone marrow

Bone marrow is a trendy protein source often found in pho, and we recommend getting veal bone marrow to start with.


Tongue is often braised or boiled for hours to remove the skin and is usually pickled or corned. It carries a rich flavor due to its high fat content — homemade “lengua” tacos are a great way to try this offal!


Liver is extremely rich and buttery and is probably the most popular offal in the world. Famous in French cuisine, liver is a must-try for any food lover. We recommend trying foie gras or pâté!

Get started with offal

Offal doesn’t stop there — hearts, kidneys, tripe — there are so many delicious types of offal to try, and we hope we’ve convinced you to give offal a try. These meats are absolutely delicious and shouldn’t be ignored.
