Recipe Information
Ingredients
- 6 large Yellow onions
- 3 tablespoons Olive oil
- 1 teaspoon Salt
- 1 teaspoon Sugar
Instructions
Preheat your oven to 375°F (190°C).
Peel the onions and slice them thinly into even rings or half-moons.
Add the sliced onions to a large, oven-safe baking dish or roasting pan, spreading them out evenly.
Drizzle the olive oil over the onions and sprinkle with salt and sugar. Mix well to ensure all onions are coated evenly.
Cover the baking dish tightly with aluminum foil. This will trap the steam and help soften the onions in the first phase of cooking.
Bake covered in the preheated oven for 45 minutes. Remove from the oven and give the onions a thorough stir.
Return the dish to the oven, without the foil this time. Bake for an additional 45 minutes, stirring every 15 minutes to ensure even caramelization.
When the onions are golden brown, deeply fragrant, and soft, remove from the oven.
Allow the caramelized onions to cool completely. Divide into portions and store in airtight containers or freezer bags.
Freeze for later use for up to 3 months, or refrigerate for up to a week.
