Classic Sauce Bordelaise Reduction
A rich, velvety French classic made by reducing dry red wine with shallots, thyme, and a bouquet garni, finished with bone marrow and butter. This sauce offers a deep, savory complexity with bright herbal notes, perfectly complementing grilled steaks or roasted veal.
A little context
Originating from the Bordeaux region of southwest France, Sauce Bordelaise is a cornerstone of classical French cuisine, traditionally paired with Bœuf Bourguignon or grilled entrecôte. Authentic preparation relies heavily on the inclusion of poached beef marrow, which provides a distinct unctuous texture and depth that butter alone cannot achieve. While modern variations sometimes omit the marrow, the true version is a testament to the French respect for offal and the art of reduction, serving as a sophisticated counterpoint to rich red meats.
Method
- 01
Prepare the aromatics
In a heavy-bottomed saucepan, combine the minced shallots, crushed peppercorns, thyme, bay leaves, and 15 ml (1 tbsp) of the red wine. Place over medium-high heat and cook, stirring frequently, until the shallots are translucent and the wine has completely evaporated. Do not let the shallots brown.
- 02
Deglaze and reduce
Pour in the remaining 735 ml (3 cups + 1 tbsp) of red wine. Bring to a boil, then immediately reduce the heat to a steady simmer. Allow the liquid to reduce by about two-thirds, which should take approximately 30 to 40 minutes. The sauce should coat the back of a spoon thickly.
- 03
Add stock
Stir in the beef stock and continue to simmer until the sauce reduces further to a rich, glossy consistency that clings to the spoon. This should take another 10 to 15 minutes. Taste and adjust seasoning with salt, keeping in mind the stock may already be salty.
- 04
Prepare the marrow
While the sauce reduces, place the marrow bones in a small sauté pan with just enough water to cover them. Bring to a simmer and poach gently for 10 minutes. Remove from water, let cool slightly, then scoop out the soft, gelatinous marrow. Discard the bones.
- 05
Finish the sauce
Remove the sauce from the heat. Whisk in the poached marrow until it melts and emulsifies into the sauce. If using additional butter, whisk in the cold cubes one at a time until fully incorporated. Stir in the fresh chopped tarragon.
- 06
Strain and serve
Pass the sauce through a fine-mesh sieve into a warm serving boat or bowl, pressing gently on the solids to extract flavor but leaving the solids behind. Serve immediately over grilled steaks or roasted veal. The sauce should be warm, glossy, and deeply aromatic.
Pro tips
- ✦Ensure the wine reduction is significant before adding stock; if the sauce is too thin, it will be watery and lack depth.
- ✦If you cannot find beef marrow, substitute with 60g of cold unsalted butter whisked in at the end, though the flavor profile will be less complex.
- ✦Do not boil the sauce after adding the butter or marrow, as high heat will break the emulsion and cause the fat to separate.
- ✦Use a dry, tannic Bordeaux or Cabernet Sauvignon; sweet wines will make the sauce cloying and unbalanced.
- ✦Make the reduction base ahead of time; the flavors improve when the sauce is made a day in advance and reheated gently.

Substitutions
- beef marrow → unsalted butter (traditional but less authentic; adds gloss but lacks the gelatinous richness)
- fresh tarragon → dried tarragon (use 1/3 the amount (approx 1/2 tsp); add earlier in the simmer to rehydrate)
- beef stock → chicken stock (will lighten the color and flavor; not traditional but acceptable for poultry)
Storage
Cool completely and store in an airtight container in the refrigerator for up to 3 days. The sauce will solidify due to the gelatin in the marrow. Reheat gently in a saucepan over low heat, adding a splash of water or stock to loosen. Can be frozen for up to 2 months.
What to serve with it
- Grilled Ribeye Steak
- Roasted Veal Chop
- Braised Short Ribs
- Mashed Potatoes or Pommes Anna
- Full-bodied red wine (Bordeaux or Malbec)
FAQ
Can I make this without beef marrow?+
Yes. While the marrow is the defining ingredient of an authentic Bordelaise, you can substitute an equal amount of cold butter whisked in at the end. The texture will be glossy but the flavor will lack the distinct savory depth of the marrow.
Why is my sauce too thin?+
The sauce relies on reduction, not flour thickening. If it is too thin, return it to low heat and simmer until more liquid evaporates. If you have added the butter or marrow and it is still thin, do not boil it; instead, reduce the liquid further before finishing with the fats.
Can I use red wine vinegar instead of wine?+
No. Red wine vinegar is too acidic and lacks the body and fruitiness required. It will result in a sharp, unbalanced sauce.
