What is American cheese, really? A clear look at how processed American cheese is made, why it melts so well, and how it differs from real cheese.
American cheese is one of the most familiar — and most misunderstood — cheeses in the United States. The orange square that melts perfectly on a burger inspires both devotion and snobbery. Here's a clear, honest look at what American cheese actually is, how it's made, and why it behaves the way it does.
What American Cheese Is
American cheese is a processed cheese product made by blending real cheese (typically cheddar, Colby, or similar) with emulsifying salts, and often additional milk products, water, and other ingredients, then heating and re-forming the mixture. The emulsifiers are the key: they allow the cheese to melt into a smooth, uniform, creamy texture without separating into greasy puddles. Because of how it's made and labeled, it's often called "processed cheese," "cheese product," or "cheese food," depending on how much actual cheese it contains.
Why It Melts So Perfectly
American cheese's superpower is its melt. The emulsifying salts (such as sodium citrate or sodium phosphate) keep the proteins and fats bound together when heated, so the cheese melts into a silky, even, stable sauce rather than breaking. This is why it's unbeatable on burgers and in grilled cheese — it turns molten and creamy without the oiliness or stringiness that natural cheeses can develop. Many cooks even add a slice of American cheese to natural-cheese sauces to keep them smooth.
Why It's Orange
Most American cheese is colored orange or yellow with annatto, the same natural dye used in cheddar and other cheeses. The color is purely cosmetic and has no effect on flavor. White American cheese, uncolored, is also common, especially in delis. Both taste essentially the same.
Flavor and Texture
American cheese is mild, creamy, salty, and slightly tangy, with a smooth, soft, springy texture. It lacks the complexity and sharpness of aged natural cheeses by design — its appeal is its mellow flavor and unbeatable meltability rather than depth. Quality varies widely, from deli-sliced versions with more real cheese to highly processed individually wrapped singles.
How to Use American Cheese
American cheese excels in melted applications: cheeseburgers, grilled cheese sandwiches, patty melts, breakfast sandwiches, and creamy sauces. Its smooth melt makes it ideal anywhere you want gooey, even, stable cheese. It's less suited to cheese boards or eating on its own, where natural cheeses shine, but for melting it's hard to beat.
A Note on Labeling
Not all "American cheese" is the same. Products labeled "pasteurized process American cheese" contain the most real cheese, while "cheese food" and "cheese product" contain progressively less and more additives. Deli American cheese is often higher quality than wrapped singles. Reading the label tells you how much actual cheese you're getting.
Frequently Asked Questions
Is American cheese real cheese?
It's made from real cheese blended with emulsifiers and other ingredients, then re-formed. Depending on the proportion, it's labeled as processed cheese, cheese food, or cheese product.
Why does American cheese melt so well?
Emulsifying salts keep its fats and proteins bound when heated, so it melts into a smooth, stable, creamy texture without separating.
Why is American cheese orange?
It's colored with annatto, a natural dye used in many cheeses; the color is cosmetic and doesn't affect flavor.
