Espagnole
Brown stock, browned vegetables, and brown roux. Depth requires actual browning, not a darker filter.
Ingredients
- 1 tbsp neutral oil
- 40 g unsalted butter
- 40 g all-purpose flour
- 100 g onion, diced
- 50 g carrot, diced
- 50 g celery, diced
- 25 g tomato paste
- 1 litre unsalted brown beef or veal stock
- 1 bay leaf
- 2 thyme sprigs
- 5 black peppercorns
Measures: 1 tbsp = 15 ml; 1 tsp = 5 ml. Yields are approximate. Pan width and heat affect reduction time; the texture gets the final vote.
Method
Brown the vegetables
Heat the oil in a heavy saucepan. Cook onion, carrot, and celery over medium heat for 10–15 minutes until well colored. Add tomato paste and cook 2 minutes; transfer everything to a bowl.
Build a brown roux
Add the butter to the pan, then flour. Cook over medium-low heat, stirring, until nut brown, about 8–12 minutes. Lower heat if it develops dark specks.
Combine and simmer
Gradually whisk in stock, loosening the roux fully. Return vegetables and add bay, thyme, and peppercorns. Simmer gently, uncovered, for 45–60 minutes, skimming and stirring occasionally.
Strain
Strain without forcing the vegetables through. Aim for about 650 ml; thin or reduce as needed. Leave lightly seasoned if it will become demi-glace.
Checkpoint: Brown, savory sauce with gentle body, no burnt taste, and no raw-flour finish.
Failure modes and fixes
Bitter roux cannot be patched with sugar. Restart it. Oversalted stock becomes oversalted sauce; begin with unsalted stock.

Use as a base for demi-glace, or spoon a small amount over roast beef.
Storage and reheating
Cool promptly in shallow containers and refrigerate within 2 hours (1 hour above 90°F / 32°C). Keep at 40°F / 4°C or colder for 3–4 days, or freeze in portions. Bring reheated cooked sauces to a rolling boil; for butter-finished sauces, ideally store the base and add fresh butter after reheating. Cream sauces may separate after freezing.
