Description

Roasted Onions with Garlic and Herbs is a simple yet flavorful side dish featuring tender, caramelized onions roasted with whole garlic cloves and aromatic herbs for a rich, savory addition to any meal.


Ingredients

Scale
  • 4 medium onions (yellow, red, or a mix), peeled and quartered
  • 6 garlic cloves, peeled
  • 2 tbsp olive oil
  • 1 tsp fresh thyme leaves (or 1/2 tsp dried thyme)
  • 1 tsp fresh rosemary, chopped (or 1/2 tsp dried rosemary)
  • Salt and freshly ground black pepper to taste
  • Optional: balsamic vinegar drizzle for serving

Instructions

  1. Preheat oven to 400°F (200°C). Line a baking sheet or roasting pan with parchment paper or lightly grease it.
  2. Place the quartered onions and garlic cloves in a large bowl. Add olive oil, thyme, rosemary, salt, and pepper. Toss to coat evenly.
  3. Spread the mixture in a single layer on the prepared baking sheet.
  4. Roast for 35–40 minutes, turning once halfway through, until onions are golden and tender and garlic is soft.
  5. Optional: Drizzle with a little balsamic vinegar before serving for extra depth of flavor.
  6. Serve warm as a side dish or topping for meats, grains, or salads.

Notes

  • Use a mix of onion varieties for color and flavor contrast.
  • Leftovers can be added to sandwiches, omelets, or pureed into soups.
  • Roasting mellows the sharpness of onions and brings out their natural sweetness.
  • Double the garlic if you love a strong roasted garlic flavor.
