A savory and comforting French side dish featuring caramelized onions braised in broth and wine.

Ingredients

Scale
  • 1214 small yellow onions, peeled
  • 2 tablespoons olive oil
  • 2 tablespoons unsalted butter
  • Salt and freshly ground black pepper, to taste
  • 1 teaspoon sugar (optional, for extra caramelization)
  • 3 garlic cloves, minced
  • 1 tablespoon fresh thyme leaves (or 1 teaspoon dried)
  • 1/2 cup dry white wine (or broth)
  • 1 1/2 cups beef or vegetable broth
  • 1 tablespoon balsamic vinegar
  • Fresh chopped parsley (for garnish)

Instructions

  1. Heat olive oil and butter in a large deep skillet over medium heat.
  2. Add whole peeled onions and sear, turning occasionally, until golden brown on all sides (8–10 minutes).
  3. Season with salt, pepper, and sprinkle with sugar if using.
  4. Add minced garlic and thyme. Cook 1 minute until fragrant.
  5. Pour in white wine and simmer 2–3 minutes, scraping up browned bits.
  6. Add broth and balsamic vinegar. Liquid should come halfway up the onions.
  7. Cover and simmer gently for 25–30 minutes until onions are tender and sauce thickens.
  8. Remove lid for last 5 minutes to reduce and glaze the onions beautifully.
  9. Sprinkle with fresh parsley and serve warm.

Notes

  • Use pearl onions for a more elegant look.
  • Keep heat moderate to avoid burning.
  • Let sauce reduce until glossy and thick.
  • Add a splash of cream at the end for richness.
