Some recipes have a bunch of good things in them, and a lot of necessary but less exciting greens to cut through the fat of, say, a few chunks of cheese or slices of avocado.This is not one of those recipes. It has all of the best things and none of those healthy interruptions: We're talking crispy bacon, heavy cream, sherry, onions, and two tablespoons of butter under a warm, gooey blanket of melted aged Cheddar. The only greenery you'll see are the chives on top, which are there purely to enhance the umami onion vibes.
This pearl onion gratin is also easy to make, and the return on investment is huge. Plus, the clock is ticking on winter, as well as your time to enjoy such a rich dish with zero guilt. It's time to turn on the broiler.
