When it comes to cooking the perfect steak, achieving the right level of doneness is crucial. The doneness of a steak is determined by its internal temperature, and one of the most debated temperatures among steak enthusiasts is 145 degrees Fahrenheit. But how done is a steak at 145, and what factors contribute to this level of doneness? In this article, we will delve into the world of steak cooking, exploring the science behind doneness, the different levels of doneness, and the importance of internal temperature.
Introduction to Steak Doneness
Steak doneness refers to the degree to which a steak is cooked, ranging from rare to well done. The level of doneness is determined by the internal temperature of the steak, which is measured using a food thermometer. The internal temperature is a critical factor in determining the doneness of a steak, as it affects the texture, flavor, and safety of the meat. A steak that is cooked to the right temperature will be juicy, tender, and full of flavor, while a steak that is overcooked or undercooked can be tough and unappetizing.
Understanding Internal Temperature
Internal temperature is the key to achieving the perfect doneness. The internal temperature of a steak is measured by inserting a food thermometer into the thickest part of the meat, avoiding any fat or bone. The temperature is then read on the thermometer, and the steak is cooked to the desired level of doneness. The internal temperature of a steak is affected by several factors, including the type of steak, the thickness of the steak, and the cooking method. For example, a thicker steak will take longer to cook than a thinner steak, and a steak cooked using a high-heat method will cook faster than a steak cooked using a low-heat method.
Factors Affecting Internal Temperature
Several factors can affect the internal temperature of a steak, including:
The type of steak: Different types of steak have different levels of marbling, which can affect the internal temperature. For example, a ribeye steak has a higher level of marbling than a sirloin steak, which means it will cook faster and have a higher internal temperature.
The thickness of the steak: A thicker steak will take longer to cook than a thinner steak, which means it will have a higher internal temperature.
The cooking method: The cooking method used can affect the internal temperature of a steak. For example, a steak cooked using a high-heat method such as grilling or pan-frying will cook faster than a steak cooked using a low-heat method such as oven roasting.
The Science of Doneness
The science of doneness is complex and involves the denaturation of proteins and the coagulation of juices. When a steak is cooked, the proteins in the meat begin to denature, or unwind, which affects the texture and flavor of the meat. The denaturation of proteins is affected by the internal temperature of the steak, with higher temperatures causing more denaturation. The coagulation of juices is also affected by the internal temperature, with higher temperatures causing the juices to coagulate and become more gel-like.
Levels of Doneness
There are several levels of doneness, each with its own unique characteristics and internal temperature. The levels of doneness are:
Rare: 120-130 degrees Fahrenheit
Medium rare: 130-135 degrees Fahrenheit
Medium: 140-145 degrees Fahrenheit
Medium well: 150-155 degrees Fahrenheit
Well done: 160 degrees Fahrenheit and above
What is 145 Degrees Fahrenheit?
A steak cooked to 145 degrees Fahrenheit is considered medium. At this temperature, the steak will be cooked through, but still retain some juiciness and tenderness. The internal temperature of 145 degrees Fahrenheit is the recommended minimum internal temperature for steak, as it ensures that the steak is cooked to a safe temperature and reduces the risk of foodborne illness. A steak cooked to 145 degrees Fahrenheit will have a pink color throughout, with a hint of red in the center.

What is the ideal internal temperature for a steak to be considered perfectly done?
The ideal internal temperature for a steak to be considered perfectly done is a topic of much debate among chefs and food enthusiasts. However, according to the United States Department of Agriculture (USDA), the recommended internal temperature for cooked steak is at least 145 degrees Fahrenheit (63 degrees Celsius). This temperature ensures that the steak is cooked to a safe level, reducing the risk of foodborne illness. It’s worth noting that the internal temperature can vary depending on the type of steak, the level of doneness desired, and personal preference.
Achieving the perfect internal temperature requires careful attention to the cooking process. It’s essential to use a food thermometer to ensure accuracy, as the internal temperature can be difficult to gauge by sight or touch alone. For medium-rare steak, the internal temperature should be around 130-135 degrees Fahrenheit (54-57 degrees Celsius), while medium should be around 140-145 degrees Fahrenheit (60-63 degrees Celsius). By cooking the steak to the recommended internal temperature, you can enjoy a perfectly cooked, juicy, and flavorful steak that meets your desired level of doneness.
How does the level of doneness affect the texture and flavor of a steak?
The level of doneness significantly impacts the texture and flavor of a steak. A steak cooked to the recommended internal temperature of 145 degrees Fahrenheit (63 degrees Celsius) will be cooked to medium, which is characterized by a hint of pink in the center. This level of doneness provides a balance of tenderness and flavor, with a slightly firmer texture than medium-rare. As the steak is cooked to higher temperatures, the texture becomes increasingly firmer, and the flavor can become more pronounced.
The texture and flavor of a steak can also be influenced by the type of steak and the cooking method used. For example, a grilled steak will have a charred, smoky flavor, while a pan-seared steak will have a richer, more caramelized flavor. Additionally, the level of marbling (fat content) in the steak can impact the tenderness and flavor, with more marbling resulting in a more tender and flavorful steak. By understanding how the level of doneness affects the texture and flavor of a steak, you can choose the perfect level of doneness to suit your taste preferences.
What are the different levels of doneness, and how are they defined?
The different levels of doneness are defined by the internal temperature of the steak, as well as the color and texture of the meat. The most common levels of doneness are rare, medium-rare, medium, medium-well, and well-done. Rare steak is cooked to an internal temperature of around 120-130 degrees Fahrenheit (49-54 degrees Celsius), with a red, juicy color throughout. Medium-rare steak is cooked to an internal temperature of around 130-135 degrees Fahrenheit (54-57 degrees Celsius), with a hint of pink in the center.
As the steak is cooked to higher temperatures, the level of doneness increases, and the color and texture of the meat change. Medium steak is cooked to an internal temperature of around 140-145 degrees Fahrenheit (60-63 degrees Celsius), with a hint of pink in the center. Medium-well steak is cooked to an internal temperature of around 150-155 degrees Fahrenheit (66-68 degrees Celsius), with a slightly firmer texture and a hint of brown color. Well-done steak is cooked to an internal temperature of around 160-170 degrees Fahrenheit (71-77 degrees Celsius), with a dry, firm texture and a brown color throughout.
How do I ensure that my steak is cooked to a safe internal temperature?
To ensure that your steak is cooked to a safe internal temperature, it’s essential to use a food thermometer. A food thermometer allows you to accurately measure the internal temperature of the steak, ensuring that it reaches the recommended temperature of at least 145 degrees Fahrenheit (63 degrees Celsius). It’s also important to insert the thermometer into the thickest part of the steak, avoiding any fat or bone, to get an accurate reading.

Can I cook a steak to 145 degrees Fahrenheit and still achieve a medium-rare level of doneness?
While it’s possible to cook a steak to 145 degrees Fahrenheit (63 degrees Celsius) and still achieve a medium-rare level of doneness, it’s not always the case. The level of doneness is determined by the internal temperature of the steak, as well as the color and texture of the meat. If you cook a steak to 145 degrees Fahrenheit (63 degrees Celsius), it will likely be cooked to medium, with a hint of pink in the center. However, if you prefer a medium-rare level of doneness, you can cook the steak to a lower internal temperature, around 130-135 degrees Fahrenheit (54-57 degrees Celsius).
To achieve a medium-rare level of doneness while still cooking the steak to a safe internal temperature, you can use a technique called “carryover cooking.” This involves removing the steak from the heat when it reaches an internal temperature of around 130-135 degrees Fahrenheit (54-57 degrees Celsius), and then letting it rest for a few minutes. During this time, the internal temperature of the steak will continue to rise, reaching a safe temperature of at least 145 degrees Fahrenheit (63 degrees Celsius) while still maintaining a medium-rare level of doneness.
How does the type of steak affect the ideal internal temperature and level of doneness?
The type of steak can significantly impact the ideal internal temperature and level of doneness. Different types of steak have varying levels of marbling (fat content), which can affect the tenderness and flavor of the meat. For example, a ribeye steak has a higher level of marbling than a sirloin steak, making it more tender and flavorful. As a result, a ribeye steak may be cooked to a higher internal temperature than a sirloin steak to achieve the same level of doneness.
The thickness of the steak can also impact the ideal internal temperature and level of doneness. Thicker steaks may require a higher internal temperature to achieve the same level of doneness as thinner steaks. Additionally, the type of steak can affect the cooking time, with thicker steaks requiring longer cooking times. By understanding how the type of steak affects the ideal internal temperature and level of doneness, you can choose the perfect steak to suit your taste preferences and cooking method.
What are the consequences of undercooking or overcooking a steak?
The consequences of undercooking or overcooking a steak can be significant.
