    This dish is a simple slow cooker ratatouille with added chicken ideal for Spring and Summer. Easy to prepare and full of goodness.

    Red serving dish with chicken and ratatouille stew, on wooden background with vegetables at the rear.

    It’s that time of year when it is warming up and yet sometimes is still freezing.

    A hot dish like this can be served whether it is a warmer or colder day so is a good all-rounder!

    French ratatouille

    We all love ratatouille, that French classic with its combination of onions, courgettes (zucchini), peppers and aubergine (eggplant).

    That combination of summer vegetables always makes me think of summer and the fresh vegetables I buy at open-air markets when in France.

    My baked ratatouille is a great option as well as a side dish to bread and cheese in high summer.

    I cook my slow cooker ratatouille using passata which ensures a thick delicious sauce rather than a thin watery sauce which slow cooker dishes sometimes sadly produce.

    The colours are so bright and vibrant, you can almost see the goodness with this palette of natural brights.

    There is no need for a lot of added ingredients when you base your dish on simple vegetables.

    Just seasoning, herbs and a few leaves of fresh basil are all that is needed!

      Great and very easy in the summer using fresh ingredients. I did add dried oregano, dried basil/parsley/thyme to the vegetable and stirred it around before adding the chicken on top & seasoning the chicken. They were the only changes I made from the recipe as written. Delicious-thank you!
