Master the art of French-inspired cooking with this simplified recipe for Demi-Glace—or its quicker counterpart, the Semi Demi-Glace. Perfect for elevating any dish, this velvety sauce combines a traditional roux with rich beef stock, red wine, tomato paste, and fragrant herbs like thyme and bay leaf. The recipe uses a classic reduction technique to concentrate flavors over time, yet offers two clever cheats: a prepared gravy mix for speedy thickening, or demi-glace concentrate to amplify depth with minimal effort. Whether you're creating a luxurious topping for steaks or enhancing roasted meats, this versatile sauce is your ticket to restaurant-quality meals at home. Ready in just over an hour (or less with shortcuts), it's an ideal blend of tradition and convenience.
In a medium saucepan, melt the butter over medium heat. Once melted, stir in the flour to create a roux. Cook for 2-3 minutes, stirring constantly, until the roux turns a light golden color.
Gradually whisk in the beef stock a little at a time to avoid clumping. Stir well to combine.
Add the red wine, tomato paste, bay leaf, thyme, and black peppercorns. Bring the mixture to a gentle simmer over low heat.
Simmer the sauce uncovered for about 40-50 minutes, stirring occasionally. During this time, the sauce will reduce and thicken to a rich consistency.
Once reduced, strain the sauce through a fine-mesh sieve to remove the solids, leaving behind your smooth demi-glace.
Season the sauce with salt to taste and serve over your desired dish (e.g., steak, lamb, or pork).
Optional Quick Cheat 1: If short on time, whisk in a prepared gravy mix during step 2 to thicken the sauce faster while still working to reduce the overall liquid.
Optional Quick Cheat 2: Add a teaspoon of store-bought concentrated beef stock (like demi-glace concentrate) to the sauce while it simmers for a deeper flavor without extensive reduction.
