Ingredients
- 2 medium red onions
- 1 medium sweet yellow onion
- 1/4 cup extra virgin olive oil
- 1 lemon juiced
- 1 teaspoon Dijon mustard
- 3 cloves garlic minced
- 2 sprigs fresh rosemary stems removed and chopped
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
Instructions
- Preheat oven to 400° F.
- Trim onion both the root and stem sides of the onion. Be sure to leave the root intact (cut so that the dried brown roots are cut off and only a white nub remains).
- Peel onions. Place onion with the cut side down on a cutting board and cut into wedges.
- Place onions onto a baking pan. Set aside.
- In a medium bowl, combine olive oil, lemon juice, mustard, garlic, rosemary, salt and pepper. Whisk until well combined.
- Pour the dressing over the onions and toss well. You can use spoons, but I think hands are the perfect tool for this job.
- Bake onions for 30 to 45 minutes, until tender and browned. Toss the onions once during cooking.
- Remove from the oven, toss again, and transfer to a serving bowl.
- Serve and enjoy!
