Caramelized onions are one of those culinary revelations that elevate dishes from ordinary to extraordinary. The process of slowly cooking onions transforms their sharp, pungent flavor into a rich, sweet, and savory delight. These sweet caramelized onions can be used in a variety of dishes, from classic French onion soup to a gourmet topping for burgers and pizzas.
Ingredients
Scale:
4 large yellow onions, thinly sliced
2 tablespoons unsalted butter or olive oil (or a combination of both)
1 teaspoon salt
1 tablespoon sugar (optional)
1 tablespoon balsamic vinegar (optional)
Instructions
Peel and slice the onions into thin, even slices.
In a large, heavy-bottomed skillet, heat the butter or olive oil over medium heat until melted.
Add the sliced onions to the skillet, stirring to coat them in the fat.
Sprinkle the salt over the onions and stir well.
Reduce the heat to medium-low and cook the onions, stirring occasionally, for about 30 to 40 minutes.
After about 30 minutes, check for color; add a splash of water or broth to deglaze the pan if necessary.
If desired, stir in the sugar and balsamic vinegar during the last 5 minutes of cooking.
Cook until the onions are deeply caramelized and have a jam-like consistency.
Once done, remove from heat and let cool. Use immediately or store in an airtight container.
