French sauce Soubise is a classic creamy onion sauce that pairs beautifully with lamb dishes, enhancing their flavors with its rich and velvety texture. This sauce is a staple in French cuisine and showcases the delicate taste of onions combined with the creaminess of béchamel. Below is a step-by-step guide on how to make French sauce Soubise for lamb.

Ingredients

  • 2 large onions, finely chopped
  • 2 tablespoons butter
  • 1 cup heavy cream
  • 1 cup béchamel sauce (see below for preparation)
  • Salt and white pepper to taste
  • Nutmeg (optional, for flavor)

Béchamel Sauce Preparation

Béchamel sauce is a fundamental element for many French sauces, including Soubise. Here’s how to make it:

  • Ingredients for Béchamel:
    • 2 tablespoons butter
    • 2 tablespoons all-purpose flour
    • 2 cups whole milk
    • Salt and white pepper to taste
    • A pinch of nutmeg (optional)

Instructions:

  • Melt the butter in a saucepan over medium heat. Once it’s bubbling, add the flour and whisk it together to form a roux, cooking for about 2 minutes without browning.
  • Gradually whisk in the milk, continuing to stir until the mixture thickens and comes to a gentle boil. Season with salt, white pepper, and nutmeg.
  • Remove from heat and set aside.

Making the Soubise Sauce

Now that you have your béchamel prepared, it's time to make the Soubise sauce.

Instructions:

  • In a skillet, melt the butter over medium heat. Add the finely chopped onions and a pinch of salt. Sauté the onions gently for about 15-20 minutes until they are soft and lightly caramelized. Make sure not to brown them too much, as the subtle flavor is key.
  • Once the onions are cooked, transfer them to a blender or food processor. Blend until smooth, and if needed, add a little water to achieve your desired consistency.
  • In a mixing bowl, combine the smooth onion mixture with the prepared béchamel sauce and heavy cream. Stir well until fully incorporated.
  • Season the sauce with salt, white pepper, and a touch of nutmeg if desired. Simmer on low heat for a few minutes to meld the flavors together.

French sauce Soubise is especially delicious when served over roasted or grilled lamb. The creamy texture and sweet onion flavor will elevate your dish to new culinary heights.

Serve the Soubise sauce warm alongside a side of mint jelly for a classic French twist on lamb. This sauce can also complement a variety of side dishes, such as sautéed vegetables or creamy mashed potatoes.
