Brown Onion Sauce for Gravy

Brown Onion Sauce for Gravy

A rich brown onion gravy sauce enhanced with port wine and mushroom ketchup, perfect for roasted meats and savory dishes. The onions are fried until golden, then thickened with a roux and enriched with stock and wine.

Ingredients

  • 2 ounces Butter, clarified or ghee (Original recipe specifies 'free of water' - clarified butter or ghee works best)
  • 6 medium White onions, finely sliced (Original calls for Patna onions; use sweet white onions)
  • 1 ounce All-purpose flour (About 3 tablespoons)
  • 1.5 cups Beef or chicken stock (Use good quality stock for best flavor)
  • 0.5 teaspoon Black pepper, freshly ground (To taste)
  • 0.5 teaspoon Salt (To taste)
  • 1 tablespoon Port wine (Ruby or tawny port)
  • 1 tablespoon Mushroom ketchup or Worcestershire sauce (Worcestershire sauce is a good modern substitute)
  • 1 teaspoon Lemon juice or vinegar (Optional, for a sharper gravy)

Instructions

  1. 1Peel and finely slice 6 medium white onions into thin, even slices.
  2. 2Heat 2 ounces of butter or ghee in a large saucepan over medium heat. Add the sliced onions and fry, stirring frequently, until they turn a light golden brown color, about 10-12 minutes.
  3. 3Gradually stir in 1 ounce of flour, mixing well to coat the onions and create a roux. Cook for 2-3 minutes, stirring constantly, to cook out the raw flour taste.
  4. 4Gradually add the stock, stirring constantly to prevent lumps. Add the salt and black pepper. Bring to a boil, then reduce heat and simmer for 5 minutes, stirring occasionally.
  5. 5Pour the sauce through a fine-mesh sieve into a clean saucepan, pressing on the solids with the back of a spoon to extract all the liquid and flavor. Discard the solids.
  6. 6Return the strained sauce to low heat. Stir in the port wine and mushroom ketchup (or Worcestershire sauce). If desired, add lemon juice or vinegar for a sharper flavor. Heat through for 1-2 minutes and serve hot.
