Fish and Sweet Potato Casserole

Like many casseroles, this Fish and Sweet Potato version lacks visual appeal. Yet casseroles have been eaten for centuries and will be for centuries to come. The resulting flavour from the mixture of fish, sweet potato and vegetables with the addition of red chilli for added flavour is worth the time taken in the slow cooker.


  • 125g/4oz Frozen White Fish
  • 1 Sweet Potato (around 125g/4oz)
  • 1 small Brown Onion
  • 50g/2oz Mixed Peppers
  • 50g/2oz Sliced Mushrooms
  • 50g/2oz Peas
  • 50g/2oz Baby Carrots
  • 50g/2oz Cauliflower Florets
  • 1 Small Red Chilli (about 2½cm/1in long)
  • (Optional) Cream Crackers
  • Salt
  • Pepper
  • bread to serve


  1. Peel and chop the onion. Put in the slow cooker pot.
  2. Peel the sweet potato then cut away the ends. Chop into 2½cm/1in pieces then add to the pot.
  3. Top and tail the chilli then slice lengthwise. Scrape out the sides and the white membranes. Chop finely then into the pot. Be sure to wash your hands at this point as chilli can sting.
  4. Add the fish and the other vegetables to the pot. I was using frozen so no preparation was required. If fresh are being used then the veggies will need to be chopped.
  5. Pour in water to cover.
  6. Add a little salt and pepper.
  7. Cover then set to cook on High for around 2 hours
  8. Two Hour Mark
  9. Stir the pot contents well so that the fish breaks up. Use the back of spoon for any larger pieces. The cauliflower will also be breaking up which is to be expected. It helps to thicken the casserole.
  10. At this point, the pot contents are likely to be more of a soup than a casserole. If a soup is the preferred choice then re-cover and cook on low for a further 2 hours. For a casserole then break up the cream crackers into very small pieces and mix in. Same 2 hour cook time.
  11. Four Hour Mark
  12. Ready to serve. Use either plates or bowls depending on the final consistency.
  13. Serve with a bread of your choice


For a slightly different flavour, substitute a dash or two of tabasco sauce for the chilli. A similar bite results yet with a subte difference.
