- 2 medium red onions
- 2 medium yellow onions
- 2 tablespoons fresh lemon juice
- 1 teaspoon Dijon mustard
- 2 garlic cloves, minced
- 1 tablespoon fresh thyme leaves
- 3/4 teaspoon kosher salt
- 1/4 teaspoon freshly ground black pepper
- 1/4 cup extra virgin olive oil
- 1 tablespoon chopped fresh cilantro
- Preheat the oven to 400°F. Cut each onion into quarters, keeping the root end still intact so wedges hold together.
- In a large bowl, combine the lemon juice, mustard, garlic, thyme, salt, and pepper. Slowly whisk in the olive oil.
- Add the onions to the bowl and mix well. Transfer the onions to a baking dish or sheet in a single layer. Bake for 30 to 45 minutes, until tender and browned at the edges. Toss the onions as necessary during cooking to ensure even browning.
- Remove onions from the oven and transfer to a serving platter. Sprinkle with the cilantro.
