Ingredients
Scale
- 4 large yellow or white onions, peeled and halved
- 4 tbsp unsalted butter, cut into cubes
- 2 tbsp olive oil
- 1 tsp sea salt
- 1 tsp freshly ground black pepper
- 1 tsp garlic powder
- 1 tbsp balsamic vinegar (optional for a sweet kick)
- Fresh thyme sprigs
Instructions
- Preheat oven to 375°F (190°C). Lightly grease a baking dish with olive oil.
- Arrange the onion halves cut-side up in the dish. Drizzle with olive oil, then sprinkle salt, pepper, and garlic powder evenly over them.
- Top each onion half with a cube of butter and a few thyme leaves. Optionally, drizzle lightly with balsamic vinegar.
- Roast uncovered for 40–45 minutes or until golden and tender, basting once or twice with pan juices.
- Garnish with extra thyme and serve hot as a side dish or appetizer.
Notes
- Use sweet onions for more depth and natural sugars.
- Don’t skip the butter — it helps caramelize the layers beautifully.
- For a vegan version, swap butter with plant-based margarine.
- Great make-ahead option; reheat at 350°F for 10 minutes before serving.
