I used to not like onions. I know what you’re thinking, who was I? And I totally agree. Who doesn’t like onions? First of all, they’re on everything. Second of all, they’re so delicious!! The first time I consciously had caramelized onions (and also watched someone make them) was back when Dave and I first started dating, and it was actually an important day in our relationship. Perhaps this is where my new love for onions comes from! There are so many great things you can do with them, but often they are an add-on to a dish, and not the dish themselves. So when I saw this tart, I just had to try it. And oh my god, it is amazing. The combination of balsamic vinegar and onions is a truly good partnership.
This dish is the perfect appetizer because it’s surprisingly light! It’s also a great dish to make while making other things, because while you don’t actually have to do a ton of work, the onions do have to sit on the stove for an hour to an hour and half. So it’s perfect to do while you’re preparing something else.
