Main course (French-inspired fine dining)
A classic French-inspired plate: perfectly seared beef tenderloin, a mosaic of wild mushrooms, and a glossy red-wine jus mounted with butter—elegant, intense, and restaurant-clean in flavor and finish. Serves 4.

(exact order, with mise en place + critical points)
Mise en place (set yourself up like a pro)
Pat the beef very dry; portion into 4 medallions and season lightly with salt (pepper later). Clean mushrooms with a brush or barely damp towel (avoid soaking—water kills browning). Slice mushrooms evenly; mince shallots; mince garlic. Cube cold butter and keep refrigerated (critical for emulsifying the sauce). Set a small pot of stock warming on low. Preheat oven to 95°C / 203°F for gentle holding (optional but helps timing).
Sear the beef (build the crust, protect the center)
Heat a heavy pan until hot; add olive oil. Lay beef in away from you; don’t move it for 2–3 minutes until a deep brown crust forms. Flip, sear 2 minutes more; add a small knob of butter and thyme, baste 30–45 seconds. Remove beef to a rack/plate and rest 8–10 minutes. Critical points: pan must be hot; meat must be dry; resting is non-negotiable for juicy slices.
Sauté mushrooms (golden, not watery)
In the same pan, add a touch more oil if dry. Add mushrooms in a single layer (work in batches if crowded). Let them brown without stirring for 1–2 minutes, then toss and continue until deeply caramelized. Season with salt near the end, add garlic for the last 30 seconds (garlic burns fast). Transfer mushrooms to a warm bowl; keep their juices.
Build the red wine jus (glossy, concentrated, balanced)
Lower heat to medium. Add shallots; sweat 60–90 seconds (soft, not browned). Deglaze with red wine, scraping fond. Reduce until syrupy—when you drag a spoon, it leaves a brief trail. Add warm stock; simmer and reduce again to a light sauce consistency. Whisk in Dijon. Critical point: reduction is your “seasoning”—too thin = weak flavor.
Mount with butter + reunite (silky restaurant texture)
Turn heat low. Whisk in cold butter a few cubes at a time to emulsify (sauce becomes shiny and slightly thick). Do not boil after butter—boiling breaks the emulsion. Return mushrooms (and any juices) to the sauce. Taste: adjust salt, add pepper now. Slide beef back in just to warm 30–60 seconds, spooning sauce over.
Plate like fine dining (clean edges, height, shine)
Slice beef against the grain or serve whole. Swipe a spoon of sauce on the plate, set beef slightly off-center, mound mushrooms beside/over, nap with jus. Finish with parsley and (optional) truffle shavings. Wipe plate rims—this single habit instantly upgrades the look.
