When it comes to cooking the perfect steak, one of the most crucial aspects to consider is the internal temperature. This is because the temperature determines the doneness of the steak, which significantly impacts its texture, flavor, and overall dining experience. In this article, we will delve into the ideal internal temperatures for a medium steak, the science behind these temperatures, and how to achieve them.
Understanding the Doneness Scale
Before we dive into the specifics of a medium steak, it's essential to understand the doneness scale. This scale ranges from rare to well-done and is based on the internal temperature of the meat. The doneness scale is as follows:
- Rare: 125°F (52°C)
- Medium Rare: 135°F (57°C)
- Medium: 145°F (63°C)
- Medium Well: 155°F (69°C)
- Well Done: 160°F (71°C)
What is a Medium Steak?
A medium steak is one that has been cooked to an internal temperature of 145°F (63°C). At this temperature, the steak is still juicy and tender, but it has also been cooked enough to develop a nice sear on the outside and a slightly firmer texture on the inside compared to a rare or medium rare steak.

Why 145°F (63°C) for Medium Steak?
The reason why a medium steak is cooked to 145°F (63°C) is that this temperature provides the best balance of flavor, texture, and food safety. At this temperature, the steak's proteins have coagulated enough to give it a firm yet tender texture, and the heat has also broken down some of the tougher connective tissues. Moreover, cooking to this temperature helps to kill any potential bacteria that may be present on the surface of the steak.
How to Achieve the Perfect Medium Steak
Now that we understand the science behind the medium steak, let's discuss how to achieve this perfect doneness at home. Here are some steps to follow:
Preparation
Start by bringing your steak to room temperature. This helps the steak cook more evenly. Then, season your steak generously with salt and pepper on both sides. Some people also like to add other seasonings like garlic powder or paprika, but the key is to keep it simple and let the natural flavor of the steak shine through.

Cooking
Preheat your oven to 400°F (200°C). Heat a cast-iron skillet or oven-safe pan over high heat until it's smoking hot. Add a small amount of oil with a high smoke point, like canola or grapeseed oil. Place your steak in the pan and sear for 2-3 minutes on each side, or until a nice brown crust forms.
Then, transfer the pan to the preheated oven and cook until the steak reaches an internal temperature of 145°F (63°C). The exact cooking time will depend on the thickness of your steak, but it typically ranges from 8 to 12 minutes.
Resting
Once the steak has reached the desired internal temperature, remove it from the oven and let it rest for 5-10 minutes. This allows the juices to redistribute throughout the steak, ensuring a moist and flavorful final product.
Using a Meat Thermometer
To ensure that your steak reaches the perfect internal temperature, it's crucial to use a meat thermometer. Insert the thermometer into the thickest part of the steak, making sure not to touch the bone if your steak has one. Here's a table to help you understand the doneness levels based on internal temperature:
| Doneness | Internal Temperature (°F) | Internal Temperature (°C) |
|---|---|---|
| Rare | 125°F | 52°C |
| Medium Rare | 135°F | 57°C |
| Medium | 145°F | 63°C |
| Medium Well | 155°F | 69°C |
| Well Done | 160°F | 71°C |
Remember, the USDA recommends cooking steak to at least 145°F (63°C) with a 3-minute rest time to ensure food safety. However, some people prefer their steak cooked to a higher internal temperature, so adjust the cooking time accordingly if you prefer a more well-done steak.
In conclusion, cooking a medium steak to an internal temperature of 145°F (63°C) ensures a balance of flavor, texture, and food safety. By following the steps outlined in this article, you can achieve the perfect medium steak at home every time. Happy cooking!
