Soubise Sauce is an onion-based sauce thicker and part of the bechamel sauce family. It is a part of French cuisine, and people generally serve this with meats, game, poultry, and vegetables.


The sauce got its name from  Charles de Rohan, Prince de Soubise. It was documented in the recipe book of Auguste Escoffier in which he had added a thickened béchamel to butter-stewed onions. There is a variance of this sauce that uses cooked rice and bacon fat. But even Escoffier prefers bechamel over that version.

Variations of Soubise Sauce

This sauce is one of the basic and is experimental also. Even if this sauce itself is a variation of the bechamel sauce, you can still derive more variation from it.

Green Garlic Soubise Sauce

The variation includes chopped green garlic/garlic cloves, boiled rice, and heavy cream. This sauce goes well with braised meat, especially a significant cut, but you can also use herbs like parsley or thyme in it.

Soubise Sauce With Cheese

It is similar to the previous version with the elimination of garlic. However, you can still experiment with a bit of garlic if you like. Starchy rice is cooked and pureed along with the cooked onions and when combined with the cream and cheese. Gruyere or Emmenthal cheese is preferred for this.

Three Ingredient Soubise Sauce

It is the easiest and also slightly tricky version. It requires only three ingredients- salt & pepper, onions, and cream. The amount of onion will increase tremendously. The trick here will be to cook/caramelize the onion without burning or changing its colour to brown. You may add a little bit of water to prevent that.

TR’s Extra Shots

  • Replacements – Replace it with heavy cream if you do not have premade bechamel sauce or cannot make it.
  • Pre-Preparation – You can make the onion and herb mixture in green garlic soubise beforehand and store it in an airtight container.
  • Flavours – This sauce is versatile. You can add more complementary ingredients to enhance its flavours. Curry powder, paprika, or other similar spice powder is okay to use.
  • Freshness – It is preferable to make this sauce when eating and avoid using the stored one. It tastes different after thawed and also tends to get more liquid afterwards.
  • Storing – If you still need to store the sauce, you can put it in the refrigerator. It will be good enough for 4-5 days. After making it, let it cool down completely before putting it in the fridge and wrapping plastic over it.
