Sauce Ingredients

  • 1 tbsp (15g) unsalted butter
  • ½ tbsp sunflower oil
  • 2 shallots (peeled and chopped finely)
  • ¼ tsp salt
  • ¼ tsp black pepper
  • 1 garlic clove (peeled and minced)
  • 2 tbsp cognac
  • 180 ml (3/4 cup) beef stock (water plus 2 stock cubes is fine)
  • 1 tsp Worcestershire sauce
  • 2 tsp Dijon mustard
  • 120 ml (1/2 cup) double (heavy) cream

Instructions

  1. Heat Butter and Oil: Add the butter and sunflower oil to a frying pan and heat over medium heat until the butter is fully melted.
  2. Sauté Shallots and Garlic: Add the finely chopped shallots, salt, pepper, and minced garlic to the pan. Cook for 2-3 minutes, stirring frequently, until the shallots begin to soften but not brown.
  3. Deglaze with Cognac: Pour in the cognac and let it bubble for about 1 minute to cook off the alcohol and incorporate the flavors.
  4. Add Stock and Seasonings: Stir in the beef stock, Worcestershire sauce, and Dijon mustard. Continue cooking for another 2-3 minutes until the sauce slightly thickens.
  5. Finish with Cream: Stir in the double cream, and if desired, add any juices from resting steak to enrich the sauce. Bring it back to a gentle simmer, then turn off the heat to avoid curdling.
  6. Serve: Pour the warm Diane sauce over freshly cooked steak immediately for a classic and flavorful accompaniment.

Notes

  • For best flavor, use fresh cognac and quality beef stock.
  • Add steak resting juices to the sauce for enhanced taste.
  • Cook over medium heat to prevent burning the shallots or cream.
  • Can be prepared while the steak is resting after cooking.
