  • Transfer the baking sheet to the oven and bake until the cheesy melts, 5 to 8 minutes.

Notes

  1. Use tuna in water. Use tuna in water and drain it well. The tuna in oil is not only less healthy but will be way too oily when mixed with the mayo.
  2. Taste for salt. After you mix all the tuna salad ingredients together, taste for salt and add more if needed. You always want to wait till the very end to add any additional salt. 
  3. Fully butter the bread. Make sure the butter is softened and that you evenly spread it all over the slices of bread so that the tuna melt bakes to a crispy golden brown.
  4. Already cooked tuna melts will keep in the fridge for up to 3 days. However, they don’t tend to freeze well. To reheat, put the sandwiches in the oven at 350°F (177°C) on a sheet pan for about 10 minutes.
