This is the start of your onion sautéing journey. Some recipes, like pureed soups or creamy sauces, call for onions to be sautéed with no color, just soft and translucent. This process takes between 5-10 minutes over medium-low and frequent stirring.
Perfect for french onion soup, grilled cheese or topping a burger! Caramelized onions are deeply golden brown, rich and flavorful. Season them with salt, pepper and a touch of vinegar to balance out the sweetness. Stir frequently and add water to the pan while the onions are cooking to prevent sticking and scorching. This process takes between 45min-1hr over medium heat.
- 4 yellow onions thinly sliced
- 4 tbsp olive oil or butter
- splash of vinegar
- Heat a large skillet or dutch oven over medium-high heat. Add in the oil/butter followed by the sliced onions and a generous pinch of salt.
- Cook until soft and translucent then turn down the heat to medium/low. Cook slowly for 45minutes to 1 hour, stirring frequently to keep the onions from burning. If you notice the onions sticking add a splash of water to deglaze and brown bits from the bottom of the pan.
- Continue cooking and adding water as needed until the onions are deeply golden brown and super soft. Season with salt, pepper and a splash of vinegar to balance out the sweetness.
