Sous-vide steak cooking: Why color isn't a key indicator

Written by Morgane Dumollard | Dec 9, 2024 4:52:28 PM

Many of us rely on color to tell if beef steak is done, assuming a nice shade of pink or brown means it’s ready. But color can be misleading, leading to steak that’s either undercooked, overcooked, or dry. Enter sous-vide cooking under the guidance of our Chef Cyrille Lecossois, Senior Lecturer at EHL and sous-vide expert: Sous-vide cooking uses precise temperature control to guarantee perfectly tender, juicy beef steack every time. Let’s dive into why sous-vide is the foolproof method for mastering steak doneness.

Why color isn’t the best guide for cooked beef steak?

Many people judge beef steak doneness by color, assuming pink means medium or brown means well-done, but color can be misleading. Factors like cut, cooking method, and lighting affect appearance, leading to steak that’s undercooked or dry and overdone. Instead of relying on color, focusing on internal temperature provides a foolproof way to perfect beef steak doneness.

The importance of temperature in sous-vide steak cooking

Sous-vide cooking uses precise temperature control to achieve doneness. By sealing beef steak in an airtight bag and cooking it in a constant-temperature water bath, sous-vide ensures even cooking from edge to center. This method allows you to set an exact temperature for your preferred doneness, locking in juices and flavors for consistently tender, juicy steak every time.

For beef steak, ideal sous-vide temperatures range as follows:

  • 56 °C for rare, resulting in tender, juicy meat with a vibrant color.
  • 58 °C for medium-rare, balancing tenderness and firmness.
  • 60 °C for medium, offering a more traditional texture while staying juicy.

Step-by-step guide to sous-vide steak cooking

Gather your tools: you’ll need a sous-vide cooking machine, a vacuum sealer, and vacuum cooking bags.

The vacuum bag acts like a second skin, protecting food from outside elements like heat, water, microbes, and bacteria, while keeping it completely safe. The bag creates a barrier without any chemical exchange between the bag and the food, ensuring no health risks and preserving the quality and taste of your ingredients.

Prepare and seal the steak: lightly season the beef steak with salt, pepper, and any preferred herbs like rosemary or thyme. Place the seasoned steak in a vacuum cooking bag. Seal tightly, using a vacuum sealer.

Always start with chilled (refrigerator-temperature) beef steak for sous-vide, but never frozen. If the steak is frozen, make sure to fully thaw it before cooking for the best, most even results.

Optional searing: for a caramelized crust, heat a skillet with oil and sear the beef steak for 1 minute per side before cooking.

Pasteurization: submerge the bag in simmering water at 83 °C for 4 minutes

Set the temperature: fill the sous-vide machine with water and set up the temperature based on desired doneness:

  • 56 °C for rare, resulting in tender, juicy meat with a vibrant color.
  • 58 °C for medium-rare, balancing tenderness and firmness.
  • 60 °C for medium, offering a more traditional texture while staying juicy.

Cook the beef steak: submerge the bag in the water and cook for 1 to 4 hours, depending on the thickness of the beef steak, the thicker the longer.

Cooling step, the 10/10/2 rule: 10 minutes at room temperature, then 10 minutes in cold tap water, finally 2 minutes in an ice bath.

Regenerate before eating: if you want to eat it hot, submerge the bag in water at 58 °C for 10 minutes. It is also possible to eat it cold.

Serve and enjoy! Serve the beef steak as is or with your favorite side dishes.

Common mistakes to avoid with sous-vide steak cooking

Sous-vide is reliable, but a few mistakes can impact results. Here’s how to avoid them:

Not sealing the bag properly: any air in the bag can cause uneven cooking. Use a vacuum sealer with vacuum cooking bags to remove all air.

Setting the wrong temperature: stick to recommended temperature. Correct temperature ensures the ideal steak texture.

Failing the cooling steps: properly cooling sous-vide steak is essential if you plan to store it for later. Cooling helps preserve texture and flavor and ensures food safety for future use.
