Demi-Glace Sauce is a finishing sauce you will find in every fine dining kitchen, the one that delivers that wow factor. It takes time, so pick a rainy day and make a big batch, then let my step-by-step instructions walk you through a foolproof version.

What is Demi Glace?
A classic Demi Glace is when you use equal parts Espagnole sauce (French mother sauce) and veal stock, and then reduce it down by half. The name "demi-glace" means half glaze.
Today, we are going to simplify the process by reducing veal stock with a mirepoix and red wine to concentrate the flavor and remove excess water, resulting in a beautiful sauce, the same classic technique used in my Chicken Demi-Glace.
We will start by making our own Veal Stock, or if you can't find veal bones, try my Instant Pot Beef Bone Broth. Once your sauce is ready, spoon it over Red Wine Braised Short Ribs, or drizzle it onto a perfectly cooked Sous Vide Ribeye Steak.
Ingredients & Substitutions
- Veal Stock - Follow my veal stock recipe, or if you can't find veal bones, make my Instant Pot Beef Bone Broth.
- Vegetables - Finely diced celery, onions, and carrots were cooked in a small amount of canola oil. I have seen some chefs use finely diced shallots instead.
- Tomato Paste - A small amount of tomato paste is used to help caramelize the vegetables.
- Sugar - ½ teaspoon of sugar helps caramelize the vegetables; this step is optional.
- Red Wine - Use a Cabernet Sauvignon, Merlot, or Pinot Noir.

How to Make Demi-Glace
Step 1. Caramelize Vegetables
Place canola oil in a large saucepan (I use a Dutch oven) over medium-high heat. Add the onion, carrot, and celery. Cook until lightly browned (1-2 minutes). Add the sugar and cook until caramelized (not burnt).
Stir in the tomato paste and cook it for another couple of minutes to remove the acidity and add flavor.
Step 2. Deglaze with Wine
Pour in the red wine and scrape up all those browned bits (the fond) and cook until reduced by 75 percent (3 to 4 minutes).
Step 3. Add the Veal Stock
Pour in the veal stock and bring to a gentle simmer
Step 4. Reduce
Let simmer and reduce for 2 hours over a medium-low heat.
Step 5. Strain
Place a fine mesh strainer over a bowl and pour reduced veal stock through it to catch the mirepoix (finely diced vegetables).
Step 6. Reduce Again
Return the liquid to the pot, bring to a slow simmer, and reduce until you have 2 cups of demi-glace left (it will coat the back of a spoon).
Serve: Use the sauce right away or cook it to room temperature and freeze it in ice cube trays.
Chef Tips
- Skim often: Skim every 15 to 20 minutes to remove impurities and keep the sauce clear.
- Caramelize Vegetables: Lightly caramelize the diced vegetables and avoid burning them because scorched veg will ruin the entire batch.
- Choose a good wine: You want to deglaze with a red wine that won't break the bank, but something you would drink.
- Reduce low and slow: Let the veal stock reduce over a medium-low heat for 2 hours for that rich flavor.
- Spoon coat test: Dip a spoon into the sauce. It should coat the back of the spoon, and when you swipe a finger through it, the line should stay put.
