2. Try Mayo Instead of Butter
Most of us use butter to help toast the bread for grilled cheese and add flavor to it. If you want to add a little bit more flavor, try using mayonnaise instead. The mayonnaise can do everything butter can do and will make the bread golden brown and delicious.
It has the perfect amount of tanginess to give the grilled cheese a bit more flavor. It works well with the nuttiness of the cheese and brings out the flavors of your bread as well. If you don’t think grilled cheese is a grilled cheese without butter, you can add both and still get good results. Just butter the inside of the bread and add the mayo to the outside pieces that will touch the surface of the pan.
Even though the butter isn’t being toasted onto the bread, it will still get warm, and when it melts, it will release all its flavor into the sandwich.
