Cooked slowly at high temperatures, onions begin to caramelize and become quite sweet. Usually looked at as an underlying component to flavor a dish, these onions are the star. Definitely worth a try!
These onions can be served hot or prepared ahead of time and served at room temperature. Leftovers can be added to a sandwich or homemade pizza – if there are any leftovers.
- 2 tablespoons freshly squeezed lemon juice
- 1 teaspoon Dijon mustard
- 1 minced garlic clove
- ½ tablespoon minced fresh thyme leaves (or ½ teaspoon dried thyme leaves)
- ¾ teaspoon kosher salt
- ¼ teaspoon freshly ground pepper
- ¼ cup olive oil
- 1 large or 2 medium red onion(s) cut into wedges
- 1 Spanish onion cut into wedges (Here’s an instructional video.)
- ½ tablespoon minced fresh parsley
- In a large, zip-top, plastic bag combine the lemon juice, mustard, garlic, thyme, salt, pepper and olive oil.
- To prepare the onions, remove the stem end (pointed end) of each onion and carefully slice off the brown part of the root end so that you leave the root intact.
- Remove the onion’s peel and cut each onion in half from root to stem.
- Continue to cut each onion half into wedges through the root so that the wedge remains whole. (View a tutorial on cutting onions into wedges.)
- Add the onions to the bag with the marinade and place into the refrigerator for 30 minutes.
- After 30 minutes, preheat the oven to 400 degrees.
- Remove the onions from the bag with a slotted spoon and place them on a baking sheet. Reserve the marinade.
- Bake the onions for 15 minutes then toss the onions so that the other sides can cook evenly.
- Put the onions back into the oven for another 15 to 30 minutes or until tender and browned.
- Remove from the oven, drizzle with the reserved marinade and sprinkle with parsley. Serve warm or at room temperature.
