Ingredients
4 large red onions (about 2 lbs / 900 g), thinly sliced
2 tablespoons olive oil
1/2 cup (100 g) granulated sugar
1/4 cup (60 ml) balsamic vinegar
1/4 cup (60 ml) red wine vinegar
1/2 teaspoon salt
1/4 teaspoon black pepper
1 sprig fresh thyme (optional)
Instructions
Heat olive oil in a large heavy-bottomed pot over medium heat. Add sliced red onions and cook, stirring occasionally, until softened and translucent, about 10 minutes.
Reduce heat to low. Add sugar, balsamic vinegar, red wine vinegar, salt, pepper, and thyme sprig if using. Stir to combine.
Cook on low heat, stirring occasionally, until the onions are very soft and the liquid has reduced to a syrupy consistency, about 35-40 minutes. The jam should be thick and dark.
Remove from heat. Discard thyme sprig. Let cool slightly, then transfer to a clean jar. Store in the refrigerator for up to 2 weeks.
Tips
For a smoother jam, pulse the finished jam in a food processor a few times.
This jam makes a great gift; sterilize the jar before filling.
Serve with cheese, on burgers, or alongside roasted pork or chicken.
