As of December 2025, we’ve revised cooking times for all our proteins to reflect improved food safety guidance.

Check out the latest recommended times in our Cooking Guidelines.

Before you start

  • Pull out 2 medium frying pans, a measuring jug, a peeler & a sieve

Prep & soften the veg

  • Peel and finely dice the parsnip and carrot into 1cm chunks. Finley dice the shallot
  • Heat a medium frying pan with 2 tsp oil on medium-high heat. Once hot, add the carrot, parsnip and shallot and cook for 6-8 mins, until softened
  • Add the garlic herb paste and cook for 1 min

Make the stock mixture & prep

  • Meanwhile, dissolve the half pack of cornflour in the jug with 50ml cold water (25ml for 1 person). Add the stock powder and top up with 100ml hot water (50ml for 1 person)
  • Finely chop the dill. Drain and rinse the beans. Pick any woody stalks from the kale

Get your simmer on

  • Add the beans and stock mixture to the veg pan, then simmer for 5 mins, until reduced by half
  • Add the cream and continue to simmer for 8-10 mins, until thickened
  • In the final 3-4 mins of cooking, add the kale and half the dill, stirring to wilt. Add a splash of water if it becomes too dry

Get sizzlin'

  • Meanwhile, season the tuna with salt and pepper
  • Heat the other medium frying pan with 1 tbsp p oil on medium-high heat. Once hot, add the tuna and cook for 7 mins per side, until golden and cooked through

Plate up

  • Check your fish is cooked through; it should be steaming hot, opaque and separate easily with a fork
  • Share the bean cassoulet between bowls, topped with the tuna. Sprinkle over the remaining dill
