Ingredients
1/2 cup organic beef broth
2 tablespoons canola oil
1 pound cremini mushrooms, sliced (or white button, baby portabella, or mixed gourmet varieties)
2 teaspoons minced garlic
1/2 cup red wine
1/4 cup prepared demi-glace
2 tablespoons butter
1 tablespoon Cognac
Freshly ground black pepper to taste
Directions
Heat canola oil in a large sauté pan over medium-high heat. Once shimmering, add the sliced mushrooms in a single layer and cook for 3 minutes, stirring occasionally, until they soften and release their moisture.
Stir in the minced garlic and cook for 1 additional minute, stirring constantly, until fragrant.
Pour in the beef broth, red wine, and demi-glace, stirring to combine. Reduce the heat to low and simmer gently for 5–7 minutes, until the sauce is visibly thickened and reduced by approximately half.
Remove the pan from heat and stir in the butter until completely incorporated and the sauce achieves a glossy, silky finish.
Add the Cognac and season to taste with freshly ground black pepper. Stir gently to combine.
Transfer the sauce to a serving vessel and serve immediately alongside perfectly cooked steak.
Comments
Demi-glace is the real hurdle here: most Charlotte stores do not stock it, forcing a trip to a specialty grocer or online order, which turns a weeknight sauce into a project. The rest of the ingredients are routine, but the Cognac and red wine add $8–12 to what should be a $3–5 side, and you are really paying for the alcohol that cooks off. The stated 25 minutes is honest if you have the demi-glace on hand, but sourcing it adds hours or a special errand. This is a dinner-party move, not a Tuesday shortcut, and it does not reheat well—same-night only.
