  • 2 thyme sprigs

  • 1 bay leaf

  • 1 1/2 teaspoons whole black peppercorns

  • Pinch of crushed red pepper

  • 4 tablespoons unsalted butter

  • 4 medium onions, coarsely chopped

  • 4 garlic cloves, peeled

  • 1 small baking potato, peeled and cut into large dice

  • 2 tablespoons dry white wine

  • 1 1/2 teaspoons sherry vinegar

  • Salt and freshly ground black pepper


  1. Wrap the thyme, bay leaf, peppercorns and crushed pepper in a piece of cheesecloth and secure with kitchen string. In a medium saucepan, melt the butter. Add the onions, garlic, potato, wine and the herb bundle and bring to a simmer over moderately high heat. Reduce the heat to low, cover and cook until the onions are very soft, about 2 1/2 hours.

  2. Drain the vegetables, reserving the cooking liquid; discard the herb bundle. Transfer the vegetables to a food processor and puree with 2 tablespoons of the cooking liquid and the vinegar. Pass the puree through a sieve, then transfer to a bowl, season with salt and ground black pepper and serve warm.

Make Ahead

The puree can be refrigerated for 2 days. Rewarm over low heat.
