Equipment

  • Sous Vide Cooker
  • Sous Vide Container
  • Vacuum Sealer
  • Vacuum Seal Bags
  • Cast Iron Skillet
  • Metal Pot

Ingredients
  

  • 14 Ounce Beef Flank (400g)
  • 1/2 Onion
  • 5 Basil Leaves
  • 2 Garlic Cloves
  • 1 tbsp Chopped Dried Rosemary
  • 14 Ounces Tomato Purée (400g)
  • 1 tbsp Butter
  • 5 Sage Leaves
  • 1 tbsp Paprika Powder
  • 1 tbsp Curry Powder
  • 3 tsp Salt

Instructions
 

  • Set the sous vide cooker at 52°C / 125.6°F. While the water heats, we'll first prep the beef flank with a good sear.
  • Take a cast iron skillet and heat it over high heat. Once it's very hot, place the flank on it and sear all sides to lock in the juices.
  • Don’t let it cook for a long time. 30-60 seconds on each side should be enough.
  • Once the water it heated, put the beef inside the vacuum seal bag and seal it. No need to add other ingredients into the bag.
  • Cook the flank for 30 hours.
    In the meantime, we can prepare the tomato sauce.
  • Place a pot over medium heat.
  • Finely chop the 1/2 onion. When done, add 2 tbsp of olive oil and the chopped onion inside the pot.
    Fry over low heat for 2minutes.
  • Add the peeled garlic cloves and basil leaves. Also pour in the tomato purée.
  • Let it cook for 15 minutes over the lowest heat possible.
  • After 15 minutes, we have a tomato sauce that's almost ready. It still needs to be spiced and seasoned.
  • Now add everything else. Add the butter, sage leaves, paprika powder, curry powder, dried rosemary, and the 3 tsp of salt in the tomato sauce.
  • Let it cook for another 2 minutes.
    Test the sauce and if it tastes a bit acidic, add 1 tsp of sugar to compensate and remove the acidity.
  • When done, take it off the stove and keep refrigerated until the flank is done.
  • Once the meat is perfectly cooked, you just need to slice it down and serve glazed with our spiced tomato sauce.

    I love flank steak because it’s lean, but it’s always been tough to find a way to cook them to make them more tender. Sous vide is definitely a good option.
