It is a treat when you discover something new and truly unexpected. Especially when you realize you have not been using sous vide to it’s fullest potential.  I was not aware you could use sous vide for making all sorts of confit. With his love for artisanal cooking his recipe is created and shared by Joris: an onion sous vide. He is making a whole range of vegetable confits.

Sous Vide Onion Confit Ingredients:

  • 1kg of onions, cut into 2.5 cm slices
  • 6 garlic cloves
  • Salt & Pepper to taste
  • 2 tablespoons of fresh Thyme
  • 480 ml of Olive Oil
  • 240 ml of vegetable oil


  • Combine onions and garlic in a sous-vide bag (or vacuum bag), season with salt & pepper and let them sit for about 10 minutes to absorb the salt
  • Cover the onions with the oil, seal the sous vide bag
  • Place in sous vide machine at 80°C for 6 hours
  • Strain, reserving the oil for another use. 
  • Refrigerate the onions in a jar until ready to use. 
  • This should keep at least for 3 months.
