Whiskey Steak Sauce with Brown Butter and Thyme
A rich and silky whiskey steak sauce made with browned butter, caramelized shallots, and fresh thyme. This smooth, refined sauce adds warm, aromatic depth to any cut of beef.
Ingredients
- 300 ml strong beef broth
- 3 tbsp unsalted butter divided (2 tbsp for cooking + 1 tbsp cold for finishing)
- 2 large shallots finely chopped
- 2 tbsp brown sugar
- 75 ml whiskey
- 2 fresh thyme sprigs
- Salt to taste
- Freshly cracked black pepper generous amount to taste
Instructions
Brown the butter:
- In a medium saucepan, melt 2 tbsp butter over medium heat until golden and nutty, about 2–3 minutes.
Caramelize the shallots
- Add the chopped shallots and cook for 4- 6 minutes until softened and golden. Stir in the brown sugar and cook 1–2 minutes more.
Deglaze with whiskey and Add Broth
- Increase the heat to medium-high, pour in the whiskey, and let it bubble for 45–60 seconds to soften the alcohol.
- Add the beef broth and thyme sprigs. Simmer for 7-10 minutes, until the liquid has reduced by about half.
Strain
- Remove from heat and pour the sauce through a fine sieve, discarding the shallots and thyme for a smooth, refined texture.
- Return the strained sauce to the pan (off heat) and whisk in the cold tbsp of butter until glossy.
- Add salt and a generous amount of black pepper to taste. Spoon over steak just before serving.
Notes
For a deeper thyme flavor, lightly bruise the thyme sprigs before simmering.
Reduce slightly longer for a thicker, more glaze-like consistency.
This sauce pairs beautifully with French fries, crispy roasted potatoes, oven-roasted vegetables, steak frites, or a dollop of truffle butter on top of the steak.
Reheat gently and whisk in a small piece of butter before serving to restore the shine.
