The world of steak cooking is filled with nuances and debates, and one of the most contentious issues is the ideal internal temperature for medium rare. For years, chefs and home cooks alike have argued over the perfect temperature, with some swearing by the traditional 130-135 degrees Fahrenheit, while others claim that 120 degrees is the true mark of a medium rare steak. In this article, we will delve into the world of steak cooking, exploring the science behind internal temperatures, the history of medium rare, and the expert opinions that will finally put this debate to rest.
Understanding Internal Temperatures
When it comes to cooking steak, internal temperature is the most critical factor in determining the level of doneness. The internal temperature of a steak refers to the temperature at the thickest part of the meat, and it is measured using a food thermometer. The United States Department of Agriculture (USDA) recommends cooking steak to an internal temperature of at least 145 degrees Fahrenheit to ensure food safety. However, this temperature is generally considered to be medium or medium-well, and it is far from the tender, pink center that steak lovers crave.
The Science of Medium Rare
Medium rare is a level of doneness that is characterized by a warm red center and a juicy, tender texture. The science behind medium rare is rooted in the denaturation of proteins, which occurs when the internal temperature of the steak reaches a certain threshold. At around 120-130 degrees Fahrenheit, the proteins in the meat begin to unwind and reorganize, resulting in a more tender and flavorful steak. However, if the internal temperature exceeds 140 degrees Fahrenheit, the proteins will continue to denature, leading to a tough and dry texture.
The Role of Myoglobin
Myoglobin is a protein found in muscle tissue that plays a crucial role in the color and flavor of steak. When myoglobin is exposed to heat, it undergoes a series of chemical reactions that result in the formation of metmyoglobin, a brownish pigment that gives cooked meat its characteristic color. At 120 degrees Fahrenheit, the myoglobin in the steak is still intact, resulting in a pink or red color that is characteristic of medium rare. However, as the internal temperature increases, the myoglobin will continue to break down, resulting in a more brownish color.
The History of Medium Rare
The concept of medium rare has been around for centuries, and it is rooted in the traditional French culinary technique of cooking steak to a specific level of doneness. The term “medium rare” was first coined in the late 19th century, and it referred to a level of doneness that was between rare and medium. Over time, the definition of medium rare has evolved, and it is now generally accepted to refer to a steak that is cooked to an internal temperature of 130-135 degrees Fahrenheit.
Expert Opinions
So, is 120 degrees really medium rare? According to some experts, the answer is yes. Chef Thomas Keller, owner of the Michelin three-star restaurant The French Laundry, is a proponent of cooking steak to 120 degrees Fahrenheit. Keller argues that this temperature results in a more tender and flavorful steak, with a warm red center that is characteristic of medium rare. However, other experts disagree, arguing that 120 degrees is too low and will result in a steak that is undercooked and potentially unsafe to eat.
A Matter of Personal Preference
Ultimately, the question of whether 120 degrees is medium rare is a matter of personal preference. Some people prefer their steak cooked to a lower internal temperature, resulting in a more tender and juicy texture. Others prefer their steak cooked to a higher internal temperature, resulting in a more well-done texture. The key is to find a temperature that works for you and to use a food thermometer to ensure that your steak is cooked to a safe internal temperature.
Conclusion
In conclusion, the question of whether 120 degrees is medium rare is a complex one that depends on a variety of factors, including personal preference, the type of steak, and the level of doneness. While some experts argue that 120 degrees is too low and will result in an undercooked steak, others claim that it is the perfect temperature for a medium rare steak. By understanding the science behind internal temperatures and the history of medium rare, we can make informed decisions about how to cook our steak and ensure that it is cooked to a safe and delicious internal temperature.

What is the definition of medium rare, and how does it relate to the internal temperature of meat?
The definition of medium rare is often subjective and can vary depending on personal preferences and cultural traditions. However, in the context of cooking meat, medium rare is generally understood to refer to a level of doneness where the meat is cooked to an internal temperature that is high enough to ensure food safety, but still low enough to retain a significant amount of juiciness and tenderness. This is particularly important for red meats like beef, lamb, and venison, where the internal temperature can greatly impact the overall texture and flavor of the meat.
In terms of internal temperature, the USDA recommends cooking ground meats to an internal temperature of at least 160°F (71°C) to ensure food safety. For whole muscle meats like steaks and roasts, the recommended internal temperature is at least 145°F (63°C) for medium rare. However, some chefs and cooking experts argue that 120°F (49°C) is a more accurate internal temperature for medium rare, as it allows for a more tender and juicy texture. Ultimately, the ideal internal temperature for medium rare will depend on personal preference and the type of meat being cooked.
How does the internal temperature of meat affect its texture and flavor?
The internal temperature of meat has a significant impact on its texture and flavor. When meat is cooked to a higher internal temperature, the proteins on the surface of the meat begin to denature and contract, causing the meat to become tougher and drier. On the other hand, when meat is cooked to a lower internal temperature, the proteins remain more relaxed, resulting in a more tender and juicy texture. Additionally, the internal temperature of meat can also affect the distribution of juices and flavors within the meat, with lower temperatures allowing for a more even distribution of flavors and a more intense, beefy taste.
The relationship between internal temperature and texture is particularly important for red meats like beef, where the texture can range from tender and juicy to tough and chewy. For example, a steak cooked to an internal temperature of 120°F (49°C) will typically be more tender and juicy than one cooked to an internal temperature of 160°F (71°C). Similarly, the flavor of meat can also be affected by the internal temperature, with lower temperatures allowing for a more intense, beefy flavor and higher temperatures resulting in a more neutral, cooked flavor. By understanding the relationship between internal temperature and texture, cooks can better control the final texture and flavor of their meat dishes.
What are the risks associated with undercooking meat, and how can they be mitigated?
Undercooking meat can pose significant health risks, particularly for vulnerable populations like the elderly, young children, and people with weakened immune systems. The primary risk associated with undercooking meat is the potential for foodborne illness, which can be caused by the presence of pathogens like Salmonella, E. coli, and Campylobacter. These pathogens can be present on the surface of the meat or within the meat itself, and can survive even if the meat is cooked to a temperature that is slightly below the recommended internal temperature.
To mitigate the risks associated with undercooking meat, it is essential to handle and cook meat safely. This includes storing meat at a temperature below 40°F (4°C), cooking meat to the recommended internal temperature, and using a food thermometer to ensure that the meat has reached a safe internal temperature. Additionally, cooks can also take steps to reduce the risk of cross-contamination, such as washing their hands frequently, cleaning and sanitizing utensils and cutting boards, and separating raw meat from ready-to-eat foods. By following safe food handling and cooking practices, cooks can minimize the risk of foodborne illness and ensure that their meat dishes are both delicious and safe to eat.
How do different cooking methods affect the internal temperature of meat?
Different cooking methods can have a significant impact on the internal temperature of meat, with some methods allowing for more precise control over the internal temperature than others. For example, grilling and pan-frying are high-heat cooking methods that can quickly raise the internal temperature of meat, while slower cooking methods like braising and stewing can result in a more gradual increase in internal temperature. Additionally, the type of cooking vessel used can also affect the internal temperature of meat, with thicker, more insulating vessels like Dutch ovens and slow cookers allowing for more even heat distribution and a more consistent internal temperature.
The choice of cooking method can also impact the final texture and flavor of the meat, with some methods allowing for a more intense, caramelized crust to form on the surface of the meat. For example, grilling and pan-frying can create a crispy, well-browned crust on the surface of the meat, while slower cooking methods like braising and stewing can result in a more tender, fall-apart texture. By understanding how different cooking methods affect the internal temperature of meat, cooks can choose the best method for achieving their desired level of doneness and texture, whether it’s a rare, juicy steak or a tender, fall-apart roast.
Can the internal temperature of meat be affected by factors other than cooking time and heat?
Yes, the internal temperature of meat can be affected by factors other than cooking time and heat. For example, the thickness and shape of the meat can impact the rate at which it cooks, with thicker cuts of meat taking longer to reach a safe internal temperature than thinner cuts. Additionally, the type of meat being cooked can also affect the internal temperature, with leaner meats like poultry and pork cooking more quickly than fattier meats like beef and lamb. The presence of bones or other obstacles within the meat can also affect the internal temperature, as these can create areas of uneven heat distribution and slower cooking.
Other factors that can affect the internal temperature of meat include the starting temperature of the meat, the temperature of the surrounding environment, and the level of moisture within the meat. For example, meat that is cooked from a frozen state will take longer to reach a safe internal temperature than meat that is cooked from a refrigerated or room temperature state. Similarly, meat that is cooked in a humid environment will cook more slowly than meat that is cooked in a dry environment, as the moisture in the air can help to regulate the temperature of the meat. By understanding these factors, cooks can better control the internal temperature of their meat and achieve their desired level of doneness.
How can cooks ensure that their meat is cooked to a safe internal temperature without overcooking it?
Cooks can ensure that their meat is cooked to a safe internal temperature without overcooking it by using a combination of techniques and tools. One of the most important tools for achieving a safe internal temperature is a food thermometer, which can be used to measure the internal temperature of the meat at its thickest point. Cooks can also use visual cues like color and texture to estimate the doneness of the meat, although these can be less reliable than a thermometer. Additionally, cooks can use techniques like tenting and resting to help the meat cook more evenly and retain its juices.
To avoid overcooking the meat, cooks can also use a technique called “cooking to temperature, not time.” This involves cooking the meat until it reaches a safe internal temperature, rather than cooking it for a specific amount of time. By using a thermometer to monitor the internal temperature of the meat, cooks can ensure that it is cooked to a safe temperature without overcooking it. Additionally, cooks can also use a technique called “carryover cooking” to their advantage, where the meat is removed from the heat source when it is slightly undercooked, and then allowed to rest and finish cooking as it cools. This can help to prevent overcooking and result in a more tender, juicy final product.
What are some common myths and misconceptions about cooking meat to medium rare?
There are several common myths and misconceptions about cooking meat to medium rare, including the idea that medium rare is only suitable for high-end restaurants or special occasions. Another myth is that cooking meat to medium rare is inherently unsafe, and that it is always better to cook meat to well done to avoid the risk of foodborne illness. However, this is not necessarily true, as cooking meat to medium rare can be safe as long as it is handled and cooked properly. Additionally, some people believe that medium rare is only suitable for certain types of meat, like beef or lamb, and that it is not suitable for other types of meat like poultry or pork.
However, these myths and misconceptions can be easily debunked by understanding the science behind cooking meat to medium rare. For example, cooking meat to medium rare is not inherently unsafe, as long as it is handled and cooked properly. Additionally, medium rare can be suitable for a wide range of meats, including beef, lamb, pork, and poultry. By understanding the relationship between internal temperature and texture, and by using proper food safety techniques, cooks can achieve a delicious and safe medium rare doneness for a variety of meats.
