Your steak isn't truly "bleeding" blood; the red liquid is mostly water mixed with myoglobin, a natural protein that gives meat its color, and this liquid escapes when muscle fibers contract during cooking and relax during resting, making the steak juicier if rested properly, but can spill if cut too soon. The liquid, called purge, is normal and safe, but letting the steak rest allows the fibers to reabsorb it, preventing it from pouring out.
It's a common misnomer to refer to the red fluid in steak as blood. It's not blood, the meat juice is called myoglobin, and it results from the breaking down of muscle tissue and fat due to the cooking process. It's perfectly safe to eat, and actually quite tasty.
The red liquid seeping out of a cooked rare steak isn't blood. It is, in fact, a mixture of a protein called 'Myoglobin' and water. Myoglobin helps muscle tissue store oxygen and just like Hemoglobin, contains iron that turns red when it binds with oxygen.
Remove meat from the pan to rest in a warm place and cover loosely with foil. This lets the natural juices equalise throughout it, making the steak more tender and easy to carve. It also means that no blood will run out of the meat.
Eating beef that is slightly pink inside after cooking is generally safe, especially if it's been cooked to the recommended internal temperature. However, if you're concerned about safety, you can use a meat thermometer to ensure it reaches at least 145°F (63°C) for medium-rare or 160°F (71°C) for medium.
And that is why I have said to the Israelites, “You must not eat any creature's meat that still has blood in it. Every creature's life is its blood. Anyone who eats that kind of meat must be separated from the community of Israel.”
While a meat thermometer is the best tool, certain visual and textural cues can help identify undercooked meat:
The 3-3-3 rule for steak is a simple guideline for getting a great sear and even cooking: sear one side for 3 minutes on high heat, flip and sear the other side for 3 minutes, then reduce heat and cook for another 3 minutes (or use indirect heat) to finish to your desired doneness, then rest. This method, often adapted for thicker cuts, focuses on building a crust and gently bringing the interior to temperature for a juicy result, with some variations suggesting a 3-3-2-2 rule for more precise control.
A good-quality raw steak should feel firm to the touch and slightly moist. Steaks that are wet, slimy, exceedingly dry, sticky, slippery, or crusty could be spoiled. If you push your finger into the surface of the steak, the meat should bounce back, not stay pushed in.
This protein, mixed with water, gives the meat its red hue and turns brown when cooked due to the heat changing its structure. So, when you see red juice on a steak, it's just myoglobin doing its job, and it's perfectly safe to eat.
Washing or rinsing steak is not necessary, according to the USDA. "While washing meat and poultry to remove dirt, slime, fat or blood may have been appropriate decades ago when many slaughtered and prepared their own food, the modern food safety system doesn't require it.
As for the "blood", it's mostly myoglobin, which is a fluid found in muscles that contains oxygen. If a steak is "bloody" you're just seeing the myoglobin leak out, which is why it's recommended to let your steak rest after cooking.
The “blood” is myoglobin and needs to be reabsorbed by the meat, this process happens during resting. All of the juice that's within the meat redistributes leaving every mouthful tender and juicy.
Any red fluid you see coming out of your steak is likely water and myoglobin, not blood. What happens when you cook meat? – Myoglobin is made of a protein and a heme ring, which contains an iron atom, both of which change when meat is cooked: The protein denatures, and the state of the iron changes.
Contrary to popular belief, it's not blood. This liquid is a combination of water and myoglobin, a protein that transports oxygen in muscle cells. As the meat ages, the muscle tissue breaks down, causing the liquid and myoglobin to leak out.
Use the following timing recommendations to learn how long to rest steak so that the flavorful juices have time to distribute through your meat:
The Bavette steak, often known as the butcher's secret, has long been a hidden gem in the world of beef. This cut, taken from the lower sirloin, boasts a texture similar to flank or skirt steak but with a richer flavor profile that rewards careful preparation.
It is a protein called myoglobin, which distributes oxygen to the muscles. It is also what gives the meat and its juices a red hue, and it's perfectly normal to find in packaging. All blood has been removed from the carcass during the slaughtering process. There is no such thing as a bloody steak.
Later, in the New Testament, Jesus swept away these rules and “declared all foods clean” (Mark 7:18-19): “There is nothing outside the man which can defile him if it goes into him; but the things which proceed out of the man are what defile the man.”
Red meat contains saturated fats, which Hwang describes as fats that are solid at room temperature. While she notes that the body needs fat, too much saturated fat can increase the risk of heart disease and stroke. Meats that are high in saturated fats are also high in calories.
What is the liquid coming out of steak? Even the rarest and reddest of steaks is actually bloodless. Instead, what you're looking at is a combination of water, which makes up about 75 per cent of meat, and a protein found in muscle tissue called myoglobin.
Cooking Techniques
The high, direct heat cooks the steak quickly, sealing in juices. Broiling: Many restaurants use broilers that reach extremely high temperatures, cooking the steak from above. This method is excellent for achieving a caramelized crust while keeping the inside tender.
Rare (125–130°F)
The rare steak temp hovers between 125–130°F, yielding a cool, red middle with a super-soft texture that's tender to the point of buttery. You'll notice a slight sear on the outside, just enough to develop a hint of charred flavor, while the inside remains mostly untouched by heat.
