Chez Eddy Demi-Glace – Low Carb Low Fat

I remember the first time I tasted a truly exceptional demi-glace. It was at a small, bustling bistro in Lyon, France. The chef, a stout man with flour permanently dusted on his apron, ladled a glistening spoonful over a perfectly seared steak. The depth of flavor was astonishing – a concentrated essence of beef, vegetables, and time. It was a revelation, and from that moment, I knew I had to learn the secrets of this magical sauce. This recipe, adapted from Chef Eddy, brings that same restaurant-quality experience into your home, without the added carbs and fats that often weigh down traditional versions.

Recipe Overview

Prep Time: 30 minutes
Cook Time: 10.5 hours
Total Time: 11 hours
Yields: 8 Cups
Dietary Type: Low Carb, Low Fat

Ingredients

10 lbs veal bones or 10 lbs beef bones
2 large onions, quartered
2 medium carrots, quartered
2 small leeks, white part only, split lengthwise in half and rinsed carefully
2 stalks celery, cut into 2 inch pieces
6 medium tomatoes, whole
24 springs parsley
2 garlic cloves
2 teaspoons whole black peppercorns
1 teaspoon dried thyme
1 cup hot water
16 cups water
½ cup red wine
½ teaspoon tomato paste

Equipment Needed

Large roasting pan
Large stockpot
Slotted spoon
Fine-mesh sieve
Cheesecloth
Refrigerator

Instructions

Preheat your oven to 450 degrees F (232 degrees C). Spread the bones in a shallow roasting pan, ensuring they are in a single layer as much as possible.
Roast the bones, turning them occasionally, until they begin to brown. This process should take approximately 1 hour. Achieving a good, even browning is crucial for the color and depth of flavor in your final demi-glace.
Add the quartered onions, carrots, leeks, and celery to the roasting pan with the bones.
Continue to roast for another 45 minutes. The bones and vegetables should develop a dark golden color at this stage. Don’t be afraid of a little char – it adds complexity – but be careful not to burn them.
Carefully drain off the rendered fat from the roasting pan. Discard the fat properly (do not pour it down the drain).
Using a slotted spoon, transfer the roasted bones and vegetables to a large stockpot.
Deglaze the roasting pan by adding 1 cup of hot water to the pan. Use a spatula or spoon to scrape up any browned bits from the bottom of the pan, dissolving the flavorful cooking juices.
Pour the deglazing liquid from the roasting pan into the stockpot, ensuring you capture all those precious browned bits.
Add the tomatoes, parsley, garlic, peppercorns, thyme, and 16 cups of water to the stockpot. The water should cover the bones and vegetables completely.
Bring the mixture to a boil over high heat. Once boiling, immediately reduce the heat to the lowest setting so that the liquid gently simmers.
As the liquid simmers, skim off any foam or impurities that collect on the surface using a spoon or skimmer. This step is important for achieving a clear, clean-tasting demi-glace. Continue skimming as needed throughout the simmering process.
Cook uncovered until the liquid is reduced to half its original volume. This reduction process will take approximately 4 to 6 hours. The longer you simmer, the more concentrated the flavors will become.
Once the liquid has reduced by half, carefully strain the stock through a fine-mesh sieve lined with several layers of cheesecloth. This will remove all the solid particles, leaving you with a clear, flavorful broth.
Discard the solids (bones and vegetables) from the cheesecloth.
Wash the stockpot thoroughly to remove any remaining residue.
Return the strained liquid to the clean stockpot.
Add the red wine and tomato paste to the strained liquid in the stockpot.
Return the mixture to a boil over medium heat. Then, reduce the heat to low and simmer for another 3-4 hours, until the liquid is again reduced in half.
Occasionally remove any scum that rises to the surface during this second simmering stage.
Once the liquid has reduced again by half, carefully transfer the demi-glace to a container and refrigerate until it is completely cool.
After refrigeration, any fat will rise to the surface and solidify. Skim off the solidified fat and discard it. This step removes excess fat, contributing to the low-fat nature of this recipe.

Expert Tips & Tricks

Bone Selection: While veal bones are traditional, beef bones work perfectly well and are often more readily available and affordable. Look for bones with plenty of cartilage and marrow, as these contribute the most gelatin and flavor.
Don’t Rush the Roasting: The roasting process is critical for developing deep, rich flavors. Ensure the bones and vegetables are properly browned before proceeding to the simmering stage.
Skimming is Key: Don’t skip the skimming process! Removing impurities during simmering ensures a clean and flavorful demi-glace.
Patience is a Virtue: Making a demi-glace requires time and patience. Don’t rush the simmering process, as this is where the magic happens.
Salt to Taste: This recipe does not include salt, as the reduction process concentrates the natural salts present in the bones and vegetables. Season to taste only after the demi-glace is finished.

Serving & Storage Suggestions

Serve your homemade demi-glace spooned over grilled or roasted meats, poultry, or vegetables. It’s particularly delicious with steak, lamb chops, or roasted chicken. You can also use it as a base for other sauces, such as a classic bordelaise or a simple pan sauce.

The finished demi-glace can be stored in the refrigerator for up to 5 days. For longer storage, freeze it in individual portions using ice cube trays or small containers. Frozen demi-glace will keep for at least 6 months. To reheat, simply thaw in the refrigerator overnight or gently warm in a saucepan over low heat.

Variations & Substitutions

Herb Variations: Experiment with different herbs, such as rosemary, sage, or bay leaf, to customize the flavor of your demi-glace. Add them during the initial simmering stage.
Vegetarian “Demi-Glace”: While not a true demi-glace, you can create a deeply flavorful vegetable reduction using a similar process. Roast root vegetables like parsnips, celeriac, and beets, then simmer them with vegetable broth and herbs.
Spice it Up: Add a pinch of red pepper flakes during the simmering process for a touch of heat.
Mushroom Enhancement: Roast a pound of mixed mushrooms (such as cremini, shiitake, and oyster mushrooms) alongside the bones and vegetables for an earthy, umami boost.

FAQs (Frequently Asked Questions):

Q: Can I use a pressure cooker to speed up the process?
A: Yes, a pressure cooker can significantly reduce the simmering time. Follow the same steps for roasting and preparing the ingredients, then cook in the pressure cooker for about 2-3 hours, allowing for a natural pressure release.

Q: How can I tell if the demi-glace is reduced enough?
A: The demi-glace should be thick enough to coat the back of a spoon. It should also have a rich, concentrated flavor.

Q: Can I use store-bought beef broth instead of water?
A: While you can, using water allows for a cleaner flavor profile and better control over the final saltiness. If you do use broth, choose a low-sodium option.

Q: What if my demi-glace is too salty?
A: If your demi-glace is too salty, you can try adding a peeled potato to the simmering liquid. The potato will absorb some of the excess salt. Remove the potato before serving.

Q: How do I make sure the demi-glace is low-fat?
A: Thoroughly skimming the fat during both the simmering process and after refrigeration is crucial. Using lean bones and trimming excess fat before roasting will also help.
