This balsamic onion jam recipe delivers a sweet, rich, caramelized goodness with a savory bite. This is definitely the type of jam that elevates an ordinary grilled cheese sandwich to something a bit divine and altogether irresistible!
Put olive oil and onions in a large saucepan. Cook over medium-high heat stirring only occasionally; cook until golden, about 10-15 minutes.
Add sugar and balsamic vinegar and cook until thickened and somewhat syrup-y. Add pepper and herbs.
Ladle into sterilized half pint jars, leaving about 1⁄2” headspace.
Refrigerate after making and it can last in the fridge for 1-2 weeks.
