In classical French cooking, the five mother sauces are the starting point for hundreds of derivative sauces. While this system was codified by Auguste Escoffier over a century ago, the principles remain useful for any home cook who wants to understand how sauces work.
Béchamel is a simple white sauce made from milk thickened with a roux (equal parts butter and flour). It is the base for macaroni and cheese, gratins, and creamy soups. The key is cooking the roux briefly to remove the floury taste, then whisking in warm milk gradually for a smooth result.
Velouté is made from a light stock (chicken, veal, or fish) thickened with a roux. It is the foundation for many classic sauces served with poultry and seafood. A well-made velouté is silky and light, with the flavor of the stock as its backbone.
Espagnole is a rich brown sauce made from browned bones, mirepoix, and tomato, thickened with a dark roux. It is the base for demi-glace and hearty meat sauces. While time-consuming, a batch of espagnole can be frozen and used over months to elevate simple meals.
Tomato sauce, in the classical sense, is made with tomatoes, aromatics, and sometimes a roux. In practice, a good tomato sauce is simply good tomatoes cooked slowly with onion, garlic, and olive oil. It is the most accessible mother sauce for home cooks and the foundation of countless Mediterranean dishes.
Hollandaise is an emulsion of egg yolks, butter, and lemon juice. It requires gentle heat and constant whisking to prevent the eggs from scrambling. It is the sauce for eggs Benedict, asparagus, and many fish dishes. A blender hollandaise is a reliable shortcut for home cooks.
Understanding these five sauces gives you a framework for improvising. Once you can make a béchamel, you can create any creamy sauce by adding cheese, herbs, mustard, or spices. Once you can make a tomato sauce, you have the base for pasta, pizza, shakshuka, and more. The mother sauces are not rigid rules but flexible foundations.
