To Serve
- Grilled sourdough or ciabatta
- Grilled steak or fish
- Olive oil for finishing
Heat the olive oil in a large skillet over medium heat. Add the sliced red onion and sauté for 8–10 minutes, stirring occasionally, until the onions begin to soften.
Add the sliced garlic, red pepper flakes, golden raisins, and fresh thyme. Continue sautéing for another 4–5 minutes, allowing the garlic to become fragrant and the raisins to soften.
Stir in the honey and red wine vinegar, then season with kosher salt and black pepper. Continue cooking for another 4–5 minutes, stirring occasionally, until the onions are tender and the mixture becomes glossy, jammy, and lightly caramelized.
Transfer the onion agrodolce to a serving bowl and garnish with additional fresh thyme leaves.
Serve warm or at room temperature with grilled steak or fish, crusty bread, or as part of a Mediterranean-style antipasto platter.
- Slice the onions evenly: Slice the onions about ¼ inch thick so they hold their shape when sautéed.
- Add vinegar at the end: Stir in the red wine vinegar during the last minute of cooking to keep things bright and tangy.
- Adjust taste as needed: Add another drizzle of honey or red pepper flakes for heat or if you prefer a more sour flavor, add another splash of vinegar.
- Serve warm or at room temperature: Onion agrodolce is delicious at any temperature.
