Sous vide Cumberland sausages in onion soup with red lentils

From Cookipedia

This recipe would probably work just as well in a slow cooker, but as I've cracked my crockpot, sous vide it is.

I browned the sausages first just so they have a little colour. Cooked at 71°C (159.8°F), the lentils would still not be properly cooked so I boiled them for 10 minutes first. Different lentils may need longer cooking.

I've used Debbie & Andrew's Cumberland sausages, but any good quality would do.

I found the Heinz onion soup to be too sweet for my test so I would try an alternative next time. A total success nonetheless.

Probably overkill!


Works fine, but probably easier done in a pan.

Mise en place


  1. Rinse the lentils in cold running water then boil for 10 minutes, skim and discard any scum. , test them before bagging up as they won't get much softer being cooked sous-vide.
  2. Drain them in a sieve.
  3. Toss the sausages, onion and garlic in a hot pan just enough to colour the sausages. Don't let them begin to cook through.
  4. Sprinkle with black pepper and add to a sous vide bag
  5. Add the onion soup and lentils to the bag and vacuum seal. If using the Andrew James Professional Quality Vacuum Food Sealer Machine: Vacuum seal, then cancel, then manually seal, allows you to vacuum seal a liquid without drawing it all into the vacuum chamber.
  6. Cook in a sous vide bath for 8 hours at 71°C (159.8°F)

Serving suggestions

This went nicely with crusty bread to dip with.


You could cook this in a slow cooker on low for about 4 hours.
