Demi-glace is an amazing sauce to serve with red meats, like roasts and grilled steaks and such. The only difficult thing about it is that making it from scratch can be quite time-consuming.

Fortunately, you can save a lot of time by making your demi-glace with store-bought beef stock or beef broth.

Purists might raise their eyebrows at this, but the reality is that if something's too hard to make, you're probably not going to make it. Which is a shame, because everyone should be able to enjoy the deep, rich, sumptuous flavor of demi-glace, which is pretty much the ultimate sauce.

No, it's not literally the ultimate sauce. You can, in fact, use demi-glace to make other sauces. Add some red wine and reduce it for a bit and you have the classic red wine sauce. Do the same with mushrooms and shallots and you have a traditional mushroom sauce.

Demi-glace is made by combining a mixture of half basic brown sauce and half brown stock (such as beef stock) and then simmering until it's reduced by half. The shortcut here is that instead of making the stock from scratch, we'll use store-bought stock or broth. It won't have the same body as a homemade demi-glace, but it'll save you about 8 hours.

Your best bet is to use the best quality stock or broth you can find, and stick to the low-sodium, reduced-salt (or even no-salt) varieties. Reducing concentrates the saltiness, and you don't want your finished sauce to taste like a salt-lick.

You'll need some cheesecloth for straining the sauce and also for making the sachet d'epices, as well as some cooking twine for tying it up.

What You'll Need

  • 5 cups beef stock
  • 1/2 cup chopped onions
  • 1/4 cup chopped celery
  • 1/4 cup chopped carrots
  • 1 fl. oz. clarified butter (2 tablespoons)
  • 1/4 cup all-purpose flour
  • 1 bay leaf
  • 1 tsp. dried thyme
  • 6 to 8 fresh parsley stems
  • 8 to 10 whole peppercorns

How to Make It

  1. Place the bay leaf, thyme, parsley stems and peppercorns onto a square of cheesecloth and tie it up into a bundle with cooking twine.
  2. Heat the butter in a heavy-bottomed pot over medium heat, and add the chopped onions, celery, and carrots. Saute them for a couple of minutes, until the onion is partially translucent.
  3. Sprinkle in the flour and stir to form a paste. Cook for about 3 minutes, stirring frequently until the flour is lightly browned, but by no means burned.
  1. Now, whisk in 3 cups of the beef stock.
  2. Bring to a boil over medium-high heat, then lower heat to a simmer, add one of the sachets and reduce for about 20 minutes or until the total volume has reduced by about one-third.
  3. Remove pan from heat and retrieve the sachet (and set it aside). Carefully pour the sauce through a wire mesh strainer lined with a piece of cheesecloth.
  4. Now, return it to the pan and stir in the remaining two cups of stock and return the sachet to the pot.
  5. Bring back to a boil and then lower to a simmer. Simmer for about 50 minutes or until the sauce has reduced by half.
  6. Discard the sachet. Strain the sauce through a fresh piece of cheesecloth. Season to taste with Kosher salt. (But if you're using the demi-glace to make another sauce, season at the very end.)

Demi-glace will keep in the fridge for a couple of weeks, and in the freezer for months.
