Caramelized Onions

Make a batch of these and keep them in the fridge!

Makes about 2 cups / Takes less than 1 hour

• 2 tablespoons olive oil
• 3 pounds sweet onions, sliced
• 2 fresh thyme sprigs
• Kosher salt
• 1 tablespoon balsamic or wine vinegar, optional

1. Combine the onions, olive oil and thyme in a large heavy skillet over moderate heat. Season with ½ teaspoon salt. Cook the mixture, stirring from time to time, until the onions are meltingly soft, browned and caramelized, 40 to 45 minutes.
2. After about 20 minutes of cooking, you will have to stir the softened onions more often, as they begin to stick to the bottom of the pan. Make sure to scrape up that browned goodness and stir it into the onions.
3. Stir in the vinegar during the last few minutes of cooking. Remove from the heat.
4. The caramelized mushrooms can be refrigerated for up to 1 week.
