Instructions
Preheat oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper.
In a large bowl, toss onion wedges with olive oil, salt, pepper, and dried herbs (if using) until evenly coated.
Spread onions in a single layer on the prepared baking sheet, positioning cut sides down for better caramelization.
Roast for 18–22 minutes until the bottoms are golden, then flip the wedges and continue roasting 15–20 minutes more, until tender with crisped edges.
Remove from the oven and drizzle with alcohol-free balsamic or lemon juice (if using). Toss lightly on the pan to coat.
Garnish with parsley and serve warm, or cool and refrigerate for up to 4 days. Reheat at 350°F (175°C) for 8–10 minutes or microwave briefly until warmed through.
