Mary Berry Onion Sauce Recipe
Mary Berry’s Onion Sauce is a traditional British sauce made from slowly cooked onions in a creamy, savory base. It’s a versatile accompaniment, often served with roasted meats, but it also pairs wonderfully with vegetables. The slow cooking of the onions brings out their natural sweetness, which is balanced by a rich creaminess that makes this sauce both comforting and flavorful.

Ingredients
- Onions (2 large, finely sliced): The base of the sauce, bringing sweetness and depth of flavor.
- Butter (2 tbsp): For cooking the onions and adding richness.
- Plain flour (1 tbsp): Helps thicken the sauce.
- Milk (300ml): Forms the creamy base of the sauce.
- Double cream (100ml, optional): Adds extra richness and a smooth texture.
- Bay leaf (1): Adds an aromatic depth to the sauce.
- Salt and pepper: To taste.
- Nutmeg (a pinch, optional): Adds a subtle warmth to the sauce.
Instructions
- Cook the onions: Melt the butter in a medium saucepan over low heat. Add the finely sliced onions and the bay leaf. Cook the onions gently for 10-15 minutes, stirring occasionally, until they are soft and lightly golden. Be careful not to let them brown too much, as this will affect the flavor.
- Make the roux: Sprinkle the flour over the softened onions and stir well to combine. Cook for 1-2 minutes to cook out the raw flour taste.
- Add the milk: Gradually whisk in the milk, ensuring there are no lumps. Bring the mixture to a simmer and continue to cook, stirring constantly, until the sauce thickens and becomes smooth.
- Stir in the cream: Once the sauce has thickened, stir in the double cream (if using) for an extra creamy texture. Add a pinch of nutmeg if desired, and season with salt and pepper to taste.
- Simmer and serve: Allow the sauce to simmer gently for 5 more minutes to ensure the flavors meld together. Remove the bay leaf before serving. Serve the sauce hot over roasted meats, vegetables, or mashed potatoes.
