THE BEST STEAK COMPOUND BUTTER

 

Romain Avril

đŸ„© L’EntrecĂŽte Sauce (CafĂ© de Paris–style compound butter)

This is a take of the legendary l’Entrecîte sauce, inspired by the iconic Parisian steak houses where simplicity meets obsession.
A deeply aromatic butter sauce loaded with fresh herbs, Dijon mustard, anchovies, capers, spices, and just enough acidity to cut through a perfectly seared ribeye.It’s not a poured sauce —
it’s a butter that becomes a sauce, melting slowly over hot steak and mixing with resting juices to create something rich, savoury, and unmistakably French.
Paired with entrecîte and fries, this sauce doesn’t need reinvention — only respect.

Method
 

Sweat the shallots
  1. In a small pan, gently cook shallots in a tiny knob of butter or neutral oil.
  2. No colour. Let cool completely.
Build the butter
  1. In a bowl, cream the soft butter with Dijon until smooth.
Fold everything in
  1. Add shallots, garlic, herbs, anchovy paste, capers, spices, Worcestershire, cognac, lemon juice + zest.
  2. Mix gently — do NOT whip air into it.
Taste & adjust
  1. It should be: Herbal 🌿, Savoury 😈, Slightly tangy 🍋, Deeply buttery 🧈
Rest (non-negotiable)
  1. Wrap in parchment or plastic, roll into a log.
  2. Refrigerate at least 2 hours (overnight is better).
đŸ”„ To serve (this is the magic)
  1. Grill or pan-sear entrecĂŽte / ribeye hard.
  2. Rest steak properly.
  3. Slice a thick coin of the butter on top.
  4. Let it melt with steak juices → instant sauce.
  5. Serve ideally with fries or mash. No discussion.

Notes

💡 Chef notes (very French, slightly judgmental)
If your butter melts into oil → it was too warm or overmixed
If it tastes flat → you forgot acidity
If it tastes salty → congratulations, anchovies did their job
