🥘Ingredients

For the Jam

4 large yellow onions, thinly sliced
3 tablespoons unsalted butter
1 tablespoon olive oil
1/2 teaspoon salt
1/4 cup brown sugar, packed
1/4 cup balsamic vinegar
1/4 cup red wine vinegar
1/2 teaspoon black pepper
1/4 teaspoon dried thyme

👨‍🍳Directions

1Heat the butter and olive oil in a large heavy-bottomed skillet over medium heat until the butter is melted and foamy.
2Add the sliced onions and salt, stirring to coat them evenly with the fat.
3Cook the onions over medium heat, stirring occasionally, for about 10 minutes until they become translucent and start to soften.
4Reduce the heat to medium-low and continue cooking, stirring every 5 minutes, for another 20 minutes until the onions are deep golden brown and very tender.
5Sprinkle the brown sugar over the caramelized onions and stir well to combine.
6Cook for 2 minutes, stirring constantly, until the sugar is dissolved and the mixture becomes glossy.
7Add the balsamic vinegar, red wine vinegar, black pepper, and dried thyme to the skillet.
8Stir everything together and bring the mixture to a gentle simmer over medium heat.
9Reduce the heat to low and let the jam simmer uncovered for 10 minutes, stirring occasionally, until the liquid has thickened and reduced by about half.
10The jam should be thick and sticky, coating the back of a spoon.
11Remove the skillet from the heat and let the jam cool for 5 minutes.
12Transfer the jam to a clean glass jar and let it cool completely to room temperature before sealing with a lid.
