When you cook a steak, you’ll notice that it releases a reddish liquid. This is commonly referred to as the “juice” in steak. But what exactly is this steak juice? Is it blood, water, fat or something else entirely?
The juice that comes out of steak when you cook it is actually a complex mixture of water, proteins, minerals and other compounds. It’s not blood, as is commonly believed. Let’s take a closer look at what makes up the juice in steak and why it’s an important component of a properly cooked steak.
Myoglobin
The major component of steak juice is a protein called myoglobin. Myoglobin is found in high concentrations in muscle tissues and is what gives muscle its red color.
When steak is raw, the myoglobin proteins contain iron atoms that are in the ferrous state (Fe2+). This causes them to appear deep red in color, hence giving raw steak its reddish hue.
During cooking, the iron atoms convert to the ferric state (Fe3+) and the protein becomes denatured. This causes the myoglobin to turn brown. The denaturing of the proteins allows the myoglobin to leach out of the muscle fibers into the surrounding juices.
So in essence, the reddish color of steak juice is coming primarily from the myoglobin protein that is released from the meat as it cooks.
Water
The second major component of steak juice is water. Raw steak consists of about 75% water. As the proteins denature during cooking, they lose their ability to hold on to water molecules, allowing some of the water to leach out into the juices.
Heat from cooking causes the water molecules to vibrate rapidly and loosen up, facilitating the release of water from within the steak.
So in addition to the myoglobin, a significant portion of steak juice is simply water inherently present in the meat that gets released during cooking.
Fat
Fat can also contribute to the juices in steak. As the trimmings and marbling in steak melt during cooking, some of the rendered fat can blend with the water and myoglobin to become part of the juice. The amount of fat will depend on the cut and grade of the steak.
Fattier cuts like ribeye will release more melted fat into the juices compared to leaner cuts like tenderloin. Heavily marbled steaks will also tend to have more fat content in their juices.
So while myoglobin and water make up the majority of steak juice, melted fat certainly plays a role as well, especially in juicier cuts of meat.
Minerals
Steak contains various minerals like iron, zinc, phosphorus and B vitamins. Small amounts of these minerals will leach into the surrounding juices as the proteins denature during cooking.
Iron is especially important, as it contributes to the color of the juice through the myoglobin protein as described earlier. But many other minerals are present in trace amounts as well.
Flavor Compounds
In addition to the major components described above, steak juice contains many flavor compounds that contribute significantly to its taste.
When steak is cooked over high heat, amino acids and sugars within the meat react at high temperatures to produce complex molecules that add flavor. Compounds like pyrazines, furans, and thiazoles emerge, giving steak juice its signature savory, meaty taste.
Maillard reactions between amino acids and sugars create flavors that people describe as “beefy” or “meaty.” Caramelization from the cooking process also creates nutty, roasted flavors.
These flavors get carried into the released juice, giving it the distinct savory taste associated with cooked steak. So while water and myoglobin make up the bulk of steak juice, the smaller flavor molecules are largely responsible for its taste.
Why Steak Juice Matters
Some people think that steak juice is wasted product that gets left behind on the plate. But retaining juices is vital for a properly cooked, flavorful steak. Here’s why:
Keeps Steak Moist
The juices in steak largely consist of water and fat that keep the meat hydrated and tender during cooking. Allowing the juices to evaporate away leads to a drier, tougher finished steak. Keeping juices locked in maintains moisture.
Concentrates Flavor
When steak juices are retained, the dissolved myoglobin, fat, minerals and flavor compounds all get concentrated within the meat itself as it cooks. This leads to more intense, beefy flavor in each bite.
Facilitates Browning
Rendered fat in steak juice helps facilitate the Maillard reaction and caramelization that leads to flavorful browning on the steak’s surface. Keeping juices present provides the necessary fat and moisture for optimal browning.
Makes a Sauce
The collected juice on a plate makes the foundation for a delicious sauce or gravy. Whisking in some butter or cream transforms simple steak juice into a rich, meaty sauce.
Indicates Doneness
The amount of clear vs. red/pink juice that runs off a steak can be used to gauge doneness. More clear juice indicates a more well-done steak.
Conclusion
While we commonly think of steak juice as a single substance, it’s actually a complex blend containing water, fat, myoglobin, minerals, and concentrated meat flavor. Allowing these juices to collect in the meat instead of running off leads to more tender and flavorful results.
Retaining the steak juice keeps the meat moist and concentrates the flavor within each bite. So next time you’re cooking steak, be sure to keep those valuable juices where they belong – in the meat!
What are some other names people use for steak juice?
Steak juice doesn’t have an official name, so people use a variety of colorful terms to describe it. Here are some common ways people refer to those savory meat juices:
– Beef Jus – A French term meaning “meat juice” that is sometimes used for the juices released by steak while cooking.
– Au Jus – From the French “with juice”, referring to a sauce made from the pan juices of cooked meat. Often used to describe steak juice.
– Meat Drippings – A descriptive term referring to the juices that drip from steak as it cooks.
– Beef Drippings – Same idea as meat drippings but specifying that the juices came from beef.
– Meat Juice – A plain and literal way to describe the liquid from cooked meat.
– Steak Blood – While not technically blood, the red color of myoglobin-rich steak juice leads some to describe it as blood.
– Mojo – An informal term meaning energy, flavor, or appeal. Used to highlight the flavor punch provided by steak juices.
– Nectar of the Gods – Humorous hyperbole that references mythology to describe savory steak juices as a heavenly delicacy.
Conclusion
While it doesn’t have any single definitive name, steak juice goes by many colorful descriptive terms referencing its origins, flavor, color, and appeal. The juices released by cooked meat go by various names but ultimately provide key moisture and flavor.
What are some tips for getting the most juice out of a steak?
Getting plenty of savory, flavorful juice from a steak requires proper cooking technique. Here are some tips to maximize the amount of juice you get:
Choose Juicy Cuts
Some cuts are naturally juicier than others. Ribeyes, New York strips and porterhouses have generous marbling that bastes the meat in its own fat during cooking. Lean cuts like filet mignon release less juice.
Don’t Overcook
Well-done steak squeezes out all the moisture and doesn’t retain as much juice. Cook to medium rare or medium to get the most juice. Check temperature with a meat thermometer.
Salt Ahead of Time
Salting steak at least 40 minutes before cooking gives the salt time to dissolve some muscle proteins. This helps retain moisture during cooking.
Pat Steak Dry
Blotting steaks with a paper towel removes excess surface moisture that can inhibit browning and flavor development.
Preheat Pan or Grill
Starting with a very hot cooking surface helps sear the meat, trapping in juices instead of slowly drawing them out.
Rest Afterwards
Letting the steak rest after cooking allows the juices to redistribute evenly throughout the meat. Slice immediately and you’ll lose juice.
Don’t Pierce Meat
Flipping or poking steak frequently squeezes out juices. Use tongs and flip only once during cooking.
Conclusion
Using the right cut, salt, temperature, and cooking method allows you to maximize the amount of flavorful juice you get out of a steak. Proper juiciness results in tender, beefy, and flavorful meat.
What types of steak produce the most juice?
Certain cuts of steak are naturally juicier due to their high fat content and marbling. Here are some steaks that tend to produce abundant, flavorful juice:
Ribeye
This well-marbled steak contains lots of fat ribbons throughout the meat. During cooking the fat melts, bastes the meat, and mixes into delicious juice.
Striploin or New York Strip
Also a marbled cut, the striploin contains a generous fat cap that renders and contributes juice. The striploin is a crossover between tender and juicy.
Porterhouse
Being a large steak with a T-bone and tenderloin, the porterhouse has plenty of fat to produce juice. The bordering fat and bone also protect the meat.
Tenderloin
While lean, the tenderloin’s fine grain and tender texture allow it to release a moderate amount of juice. Don’t overcook this lean cut.
Flat Iron
This well-marbled shoulder cut stays tender and produces ample juice. It offers great value compared to pricier loin cuts.
Hanger
From near the diaphragm, the hanger steak is loose-grained and well-flavored. It delivers great juiciness for its leanness.
Conclusion
For the juiciest results, go for steaks like ribeye, striploin, and porterhouse that combine tender textures with plenty of marbling and fat. This renders into flavorful juices during cooking while keeping the meat moist and tender. Lean cuts can still produce decent juice as long as you don’t overcook.

What are some common myths about the juice in steak?
There are some widespread misconceptions and myths floating around about the savory juices released by cooked steak. Here are some common steak juice myths debunked:
Myth: It’s blood from the meat
This is perhaps the biggest myth about steak juice. Many people believe the red liquid coming from steak is blood. In fact, it’s myoglobin – a protein that stores oxygen in muscles. Blood is removed during slaughter.
Myth: Juice indicates better quality meat
Some think more juice automatically means better quality steak. But in fact, lower quality steaks pumped with saltwater solutions can release even more juice. High juice alone doesn’t signify quality.
Myth: The more juice the better
While flavorful, excessive amounts of juice can mean the meat was undercooked and fibers weren’t allowed to properly coagulate and firm up. Some moisture loss concentrates flavor.
Myth: Juice should always be clear
Some cooks believe clear juice when cutting shows perfect doneness. But properly cooked medium-rare steak will still release some reddish myoglobin-rich juice.
Myth: Juice should be discarded
Pouring off juice means wasting incredible flavor. Well-cooked steaks with strained juice lose moisture and beefy taste. Retaining juice concentrates flavor.
Conclusion
Steak juice is a complex, flavorful product of cooking. But certain myths persist about its meaning and origins. Knowing the real science behind steak’s juices helps you better cook and appreciate this carnivorous nectar.
