Herb-Roasted Onions

Step 1: Preheat the Oven

  1. Preheat your oven to 400°F (200°C).

Step 2: Prepare the Onions

  1. Peel and trim the onions. If using large onions, slice them in half, or if using smaller onions, you can leave them whole or cut them into quarters.
  2. For whole onions, you may want to cut a small “X” into the bottom to help them cook evenly.

Step 3: Season the Onions

  1. Place the onion halves or wedges in a baking dish or on a rimmed baking sheet.
  2. Drizzle the onions with olive oil. Toss them gently to coat evenly.
  3. Sprinkle the onions with thymerosemarygarlic powderonion powdersalt, and pepper. Toss again to ensure the seasonings are evenly distributed.

Step 4: Roast the Onions

  1. Arrange the onions cut side down if you’ve halved them, or with the cut sides facing up if you’ve quartered them.
  2. Roast in the preheated oven for about 30-40 minutes, or until the onions are golden and tender. You can check the tenderness by piercing them with a fork.
  3. For a slightly caramelized effect, you can drizzle balsamic vinegar over the onions during the last 10 minutes of roasting.

Step 5: Garnish and Serve

  1. Once roasted, remove the onions from the oven and let them cool slightly.
  2. Garnish with freshly chopped parsley before serving.

Tips for Perfect Herb-Roasted Onions

  • Choosing the Right Onion: Yellow onions are the most common choice for roasting because they’re sweet and hold their shape well when cooked. However, red onions will give a slightly different, sweeter taste, while white onions are milder.
  • Customization: Feel free to experiment with other herbs like oregano, thyme, or tarragon, or even add a pinch of paprika or cumin for a different flavor.
  • Cutting the Onions: Halving the onions will give you more caramelized edges, while cutting them into wedges or quarters will result in a different texture. Both are delicious!

Serving Suggestions

  • Side Dish: These roasted onions are perfect alongside roasted meats (such as chicken, beef, or lamb), grilled vegetables, or pasta dishes.
  • Salads: Add roasted onions to a fresh salad for an extra depth of flavor.
  • Sandwiches: These caramelized onions can be used as a topping for burgers, sandwiches, or even a flatbread pizza.

Storage

  • Refrigerator: Store leftover roasted onions in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven before serving.
  • Freezer: Roasted onions can be frozen for up to 2-3 months. To freeze, spread them on a baking sheet in a single layer, freeze until firm, then transfer to a freezer-safe bag. Reheat in the oven or on the stovetop.

Final Thoughts
