Slow-Roasted Onion Dip

Like the one you make with the packet of soup mix, but with no weird chemicals and 1,000 percent tastier. While most dips like this require you to babysit caramelizing onions on the stovetop for what feels like forever, our (relatively) hands-off version lets the oven do most of the work. It's kind of counterintuitive, but you want to keep the onions and garlic in a mound on the sheet pan rather than spreading them out; this allows them to steam and soften without browning too quickly.
