Roasted Rosemary Onions

Total Time
Prep 5 mins
Cook 35 mins

This simple preparation allows the natural sweetness of the onions to shine through. Nice accompaniment to grilled or roasted meats.

Ingredients Nutrition


  1. Pre-heat oven to 350°F (180°C).
  2. Cut onions in half, top to bottom.
  3. Trim and peel each onion half, but do not cut off the root end; this will keep the onions intact as they cook.
  4. Arrange the onions in one layer in a baking dish, cut side up.
  5. Sprinkle evenly with the vinegar, followed by the oil, salt, pepper, and chopped rosemary.
  6. Cover with foil and roast for 30 minutes.
  7. Remove the foil, and broil until lightly charred, about 5 minutes.
  8. Remove from oven and drizzle with extra olive oil, if desired, then sprinkle with rosemary leaves and serve.

Cooking Light has been recommending variations of this recipe for years. I was pleased to find the recipe on 'zaar and finally decided to try it. Delicious! I used dried rosemary and it still tasted very good. Thanks for posting!

I made these to go with a roast last night and they were so tasty! I used dried rosemary because that's what I had on hand and they were delicious. The savory smell as they were roasting in the oven was a wonderful added bonus! For some reason, mine fell apart and didnt' stay in complete halves, but they were so tender and juicy, it wasn't a big deal to us! I will make this over and over again and may even try it on the grill in the future!

This smelled so good cooking in the oven! I had fairly large onions, so cooked about 20 mins. longer. I also used dried rosemary, the dish was still delicious! Thanks!
