Slow-baked maple-glazed onions and Brussels sprouts is a fantastic cool-weather side dish. Perfect for holidays or as a delicious, everyday way to use up surplus onions.
Slow-baking onions in a blend of broth, maple syrup (or agave), and olive oil heightens their mellow sweetness.
This method works especially well with onions that start out a with a bit more natural sweetness than ordinary yellow onions — though those are beyond fine to use in this dish. Brussels sprouts make a perfect partner for the onions.
