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

  • Preheat the oven to 240C / fan 220C / gas mark 9
  • Line a baking tray with baking parchment
  • Boil a half-full kettle
  • Pull out a large frying pan, a measuring jug, a peeler & a sieve

Roast the veg

  • Cut the carrots and parsnip into 1cm chunks (peel optional)
  • Place the prepped veg onto a lined baking tray and toss with 1 tsp oil, salt and pepper. Roast for 20-25 mins, until golden and softened

Prep the ingredients & toast the nutritional yeast

  • Dissolve the cornflour in the jug with 50ml water. Add the stock and top up with with 200ml boiling water
  • Thinly slice the onion. Finely chop or crush the garlic. Finely chop the dill. Drain and rinse the beans. Rinse the spinach
  • Heat the large frying pan on medium heat. Once hot, add the nutritional yeast and toast for 2-3 mins, tossing regularly, until golden brown. Remove from the pan and set aside

Make the cassoulet

  • Reheat the large frying pan with 1 tsp oil on medium-high heat. Once hot, add the onion and tuna and cook for 10 mins, until the tuna is cooked through, and the onion is soft. Season with salt and pepper
  • Add the garlic and garlic herb paste and cook for a further minute

Simmer time

  • Add the beans and stock mixture to the frying pan and simmer for 5 mins, until the liquid is reduced by half
  • Add the cashew cream, and continue to simmer for 3-4 mins, until thickened
  • In the final minute, add the roasted veg, spinach and half the dill to the stew, and stir to wilt. Season to taste with salt and pepper

Plate up

  • Check your fish is cooked through; it should be steaming hot, opaque and separate easily with a fork
  • Serve the tuna cassoulet into bowls. Sprinkle over the nutritional yeast and remaining dill
