Combine the onions and thyme leaves in a large bowl. Drizzle with the melted butter and honey, season with salt and pepper and toss to coat thoroughly.

Step 3

Arrange the onions in a single layer on the prepared baking sheet and roast the onions until tender and lightly caramelized, 18 to 22 minutes. Transfer to a bowl and serve.

Step 4

Note: This recipe may be made ahead and reheated. Remove the onions from the refrigerator 30 minutes in advance, then heat in a covered casserole at 325°F oven for 25 to 30 minutes.
