Cooking the Perfect Tenderloin Roast Using Sous Vide

Tenderloin roast is known for its tenderness and rich flavor. Cooking it using sous vide ensures you get the perfect doneness from edge to edge, with a juicy and tender result every time. In this blog post, I’ll guide you through the steps to cook a delicious tenderloin roast using sous vide, with a sear before sealing to enhance the flavor.

Ingredients

  • 1.5-2 kg beef tenderloin roast
  • Salt
  • Freshly ground black pepper
  • Garlic powder (Optional)
  • Fresh herbs (rosemary, thyme, or your favorite herbs)
  • Olive oil or butter (for searing)
  • Optional: garlic cloves, shallots, or other aromatics

Equipment

  • Sous vide precision cooker
  • Large pot or container for the water bath
  • Vacuum sealer and bags or resealable plastic bags with the water displacement method
  • Cast iron skillet or heavy-bottomed pan

Instructions

Step 1: Prepare and Sear the Tenderloin Roast

  1. Season the Roast: Generously season the beef tenderloin roast with salt, pepper, and garlic powder. You can also add fresh herbs, garlic cloves, or shallots for extra flavor.

  1. Pre-Sear the Roast: Heat a cast iron skillet or heavy-bottomed pan over high heat and add a tablespoon of olive oil or butter. Once the oil is shimmering or the butter is melted, sear the roast on all sides until a deep, brown crust forms, about 1-2 minutes per side. This step enhances the flavor by developing a rich, caramelized crust.

  1. Let it Cool: Allow the seared roast to cool slightly before sealing. This prevents the meat from cooking further and helps retain its juices.

Step 2: Vacuum Seal the Roast

  1. Vacuum Seal the Roast: Place the cooled, seared roast in a vacuum-seal bag or a resealable plastic bag. If using a vacuum sealer, seal the bag according to the manufacturer’s instructions. If using a resealable bag, use the water displacement method to remove the air. To do this, slowly lower the bagged roast into a pot of water, letting the pressure of the water push the air out, then seal the bag just above the waterline.

Step 3: Sous Vide Cooking

  1. Set Up the Water Bath: Fill a large pot or container with water. Attach your sous vide precision cooker to the side and set the temperature to 56°C for medium-rare, or adjust according to your preferred doneness:
    • Medium-rare: 54°C to 57°C
    • Medium: 60°C to 63°C
    • Medium-well: 65°C to 68°C

  1. Cook the Roast: Once the water bath has reached the desired temperature, place the bagged roast into the water. Make sure it is fully submerged. Cook for 2 to 4 hours.

Step 4: Finishing the Roast (Optional)

  1. Remove and Dry: After the cooking time is complete, remove the roast from the bag and pat it dry with paper towels. A dry surface is crucial for achieving a good final sear.

  2. Final Sear: Heat a cast iron skillet or heavy-bottomed pan over high heat again and add a tablespoon of olive oil or butter. Sear the roast on all sides for 1 minute per side to re-crisp the crust and enhance the flavor.

  3. Rest and Slice: Let the roast rest for a few minutes before slicing. This allows the juices to redistribute throughout the meat.

Step 5: Serve

Slice the tenderloin roast against the grain and serve with your favorite sides. The beef will be perfectly cooked edge to edge, juicy, and full of flavor.
