Roasted Onion Halves

Directions

1. 1
   Preheat the oven to 400°F Grease a small baking or roasting pan with a little olive oil or line it with parchment paper. Rub the onions with the 2 tablespoons olive oil and sprinkle them all over with salt and pepper.
2. 2
   Put the onions cut side down in the prepared pan. Roast, undisturbed, until they start to brown, about 20 minutes. Use a spatula to turn them over. Top with the thyme if you like, then return them to the oven for another 15 to 25 minutes, depending on how tender you want them. Check for doneness by sticking a sharp-tipped knife or skewer into the side of one. Serve hot or at room temperature.
