How to make it

  • Preheat oven to 450°F. Combine all onions and shallots in large bowl. Drizzle evenly with olive oil, then sprinkle with thyme, coarse salt, and pepper; toss gently to coat. Spread out in single layer on large rimmed baking sheet.
  • Roast onions until tender and beginning to brown in spots, 25 to 30 minutes. Scatter bread pieces on another rimmed baking sheet. Bake bread until golden brown, 7 to 8 minutes. Cool bread on baking sheet. Arrange onions in single layer in large casserole dish. DO AHEAD: Onions and croutons can be made up to 1 day ahead. Cover onions and refrigerate.
  • Store croutons in airtight container at room temperature. Bring onions to room temperature before continuing.
  • Preheat oven to 400°F. Spoon broth over onions to moisten. Scatter croutons over; sprinkle with cheese. Bake until heated through and cheese is melted, about 20 minutes. Sprinkle with sea salt flakes and serve.
