To Assemble the Gratin
To cook the onions: In a medium skillet, heat the olive oil over medium heat. Add the onions and sauté, stirring frequently, until limp and golden brown, about 20 minute Reduce the heat to medium-low if they're browning too quickly. Add the garlic and sauté until soft and fragrant, 1 to 2 minutes. Spread the onions and garlic evenly in the bottom of an oiled 2-quart shallow gratin dish (preferably oval). Let cool.
This is AMAZING!!!! Have some nice crusty bread to sop up the luscious juices. I served this as a main dish--serves 4 as a main dish, six-eight as a side. Please be sure to let this set out before serving, as the recipe instructs--it makes it a much more cohesive gratin.
