Prep time: 10 mins | Cook time: 30 mins | Serves: 4


What you will need:

  • 425g of Tuna (in brine or spring water)
  • 700ml Milk 
  • 1 1/2 Cups of cheddar cheese, grated
  • Half an onion, chopped
  • Half a can of sweetcorn kernels
  • Half a cube of beef stock
  • Tsp of corn flour
  • 8 Tbsp of butter
  • 4 Tbsp of bread crumbs



  • Pour the milk into a pan along with your chopped up onion and half of the butter
  • Bring the mixture to the heat but avoid boiling it so the milk doesn't burn but the butter is melted
  • Add the cornflour slowly and carefully so that it thickens but you haven't used too much
  • Once it has thickened, turn the heat off and add the stock. Then add the tuna, one cup of your cheese and your sweetcorn
  • Pre-heat the oven to 180°C and pour your mixture into an oven-proof bowl
  • While the oven is pre-heating, melt down the butter for the topping (four tablespoons) and pour in the breadcrumbs, mixing it round with the butter
  • This should make a crumble that will go on the top. Add the crumble and sprinkle the remaining half cup of cheese on the top
  • Put the tuna mornay in the oven on 180 degrees Celsius for 20 minutes. This should crisp it up perfectly
  • Enjoy
