Salisbury Steak with Mushroom Demi-Glace and Thyme Jus
Hand-formed beef rounds seared to a mahogany crust, finished in a silky reduction of cremini mushrooms, beef demi-glace, and fresh thyme. A refined, umami-forward reinterpretation of the American diner classic — restaurant-worthy from a single pan.

Combine ground beef, half the minced shallot, 1 minced garlic clove, Dijon mustard, 1 tbsp Worcestershire sauce, beaten egg, panko breadcrumbs, 1 tsp kosher salt, and ½ tsp black pepper in a bowl. Mix gently with your hands until just combined — do not overwork. Divide into 4 equal oval patties about 2 cm thick. Press a shallow dimple in the center of each to prevent doming. Refrigerate uncovered on a plate for 10 minutes to firm.

Heat a wide, heavy skillet (cast iron or stainless) over medium-high heat until shimmering. Add neutral oil. Season the exterior of each patty lightly with the remaining ½ tsp salt and ½ tsp pepper. Sear patties undisturbed for 3–4 minutes per side until a deep mahogany crust forms. Internal temperature should reach 160°F/71°C — confirm with an instant-read thermometer. Transfer patties to a plate and tent loosely with foil.

Reduce heat to medium. Add 1 tbsp butter to the same skillet. Once foaming, add the remaining minced shallot and cook, stirring, for 2 minutes until softened. Add the remaining 2 minced garlic cloves and cook 30 seconds until fragrant.

Increase heat to medium-high. Add sliced cremini mushrooms in a single layer as best you can. Do not stir for 2 minutes to encourage browning. Stir and continue cooking 3–4 more minutes until mushrooms are deeply golden and any liquid has evaporated.
- 5
Push mushrooms to the edges. Add tomato paste to the center and cook, pressing and stirring it into the pan, for 1 minute until it darkens slightly (this builds depth and kills raw tomato flavor).

Pour in dry red wine to deglaze, scraping up all the fond from the pan bottom with a wooden spoon. Add the remaining 1 tbsp Worcestershire sauce, beef demi-glace, beef broth, 2 fresh thyme sprigs, and bay leaf. Stir to combine and bring to a vigorous simmer.
- 7
Simmer the sauce uncovered over medium heat for 8–10 minutes, stirring occasionally, until reduced by roughly one-third and the sauce coats a spoon. If you prefer a tighter consistency, whisk in the cornstarch slurry during the last 2 minutes of simmering and stir constantly until glossy. Remove and discard the thyme sprigs and bay leaf.
- 8
Reduce heat to low. Add the remaining 2 tbsp cold butter in pieces, swirling the pan or whisking constantly to mount the sauce until it turns glossy and silky (monter au beurre). Add the remaining 3 fresh thyme sprigs and let steep 1 minute, then remove. Taste and adjust seasoning.
- 9
Return seared patties and any rested juices to the skillet. Spoon sauce generously over the top. Gently warm over low heat for 2–3 minutes — the patties should be glazed and heated through. Do not boil. Finish with chopped flat-leaf parsley. Serve immediately, spooning extra sauce tableside.
