Calories 79kcal
Ingredients
- 1/4 cup olive oil
- 1 tablespoon butter
- 6 large yellow onions thinly sliced (about 6 pounds, see note 1)
- 1 teaspoon sugar
- Salt and freshly ground black pepper
Instructions
- In a large, deep skillet or Dutch oven over medium heat, add olive oil and butter and stir until melted. Add onions, sugar, 1/2 teaspoon salt, and a pinch of pepper.
- Cook, stirring often, until the onions are deep golden brown and richly colored, about 45 to 60 minutes. Reduce heat if they begin to darken quickly. Season to taste with salt and pepper.
Notes
- Onions: You can caramelize any kind of onion, but I prefer to use yellow onions because they have the perfect balance of sweet and savory flavor. Speed up prep time by running the onions through a food processor rather than cutting onions by hand.
- Yield: 6 pounds of yellow onions will yield about 3 c. caramelized onions. It's enough for 12 servings, 1/4 c. each.
- Storage: Once they've cooled, transfer them to an airtight container and refrigerate them for up to 1 week.
