Roasted Onion Soup

Sweet caramelized onions, bolstered by roasted shallots and garlic, combine in a luscious, but not overpowering soup.


  • 3 spanish onions, cut in half lengthwise and thinly sliced
  • 3 large shallots, cut in half lengthwise and thinly sliced
  • 1 large head garlic cloves, separated, peeled and cut in half
  • 2 teaspoons extra-virgin olive oil
  • 4 cups reduced-sodium chicken broth, divided
  • 1/4 cup brandy
  • 1 tablespoon fresh thyme, chopped
  • 1/4 cup freshly grated Parmesan cheese, preferably Reggiano
  • salt, to taste
  • freshly ground pepper, to taste


Step 1
Set oven rack at the lowest level; preheat to 450°F.
Step 2
Combine onions, shallots, garlic and oil in a large shallow roasting pan. Roast, stirring every 5 minutes, until the onions are golden, 20 to 25 minutes. Remove from the oven and pour in 1 cup of the broth; stir, scraping the bottom of the pan to loosen and dissolve any caramelized bits. (The liquid will become quite dark.)
Step 3
Transfer the onion mixture to a soup pot and add brandy, thyme and the remaining 3 cups broth. Bring to a boil; reduce heat to low and simmer, covered, for 30 minutes. Season with salt and pepper. Divide between 4 bowls and sprinkle with Parmesan.
