A grilled cheese sandwich at its most basic, consists of three ingredients. Choosing the right cheese will give you the exact flavor, crunch and melt you desire. Make sure that the cheese will compliment the bread and vice versa. Texture is key, you’ll want to go for a cheese that is somewhat soft and moist. If your cheese is too cold, it may not melt before the bread is toasted. Always have it at room temperature, or if you’re short on time, cover the pan or griddle.
Top Cheese Choices
Cheddar. The most popular choice. Pick one that’s medium to sharp for a good melt-to-flavor ratio.
American. Pairs perfectly with white bread. It’s mild, salty, a little sweet and has a major melting component. A deli slice will be thicker than the plastic-wrapped versions.
Gruyère. This cheese has a nutty flavor and melts easily. It has a nice kick without being overpowering.
Gouda. The Dutch cheese is creamy, nutty and slightly sweet. A younger version will melt better.
Muenster. Popular among kids for the typically mild taste.
Parmesan. While not meant for the filling, parmesan sprinkled on the outside of your sandwich will transform it into an extra crunchy snack.
