Add the spring onion whites and simmer until just starting to soften, about 5 minutes. Season with 1 1/2 teaspoons salt and a few grinds of pepper. Remove the thyme sprigs and bay leaves. Stir in about half of the spring onion greens.
• Spread the potatoes in a 9-by-13-inch baking dish. Pour the cream mixture over the top and gently stir, pressing and submerging the potatoes to make an even layer. Cover with foil and bake until the potatoes are tender and the cream is bubbling, 45 to 55 minutes.
• Uncover the potatoes and sprinkle with the cheese. Bake until the cheese is golden, 10 to 15 minutes. Let cool 15 minutes. Sprinkle with the remaining spring onion greens just before serving.

Layer one-third of the grilled sweet potatoes and onions on top of the Gruyere. Repeat twice¿one-third of the cheese, one-third of the vegetables¿to create three even cheese-vegetable layers. Pour the half-and-half mixture over the top, cover with foil and bake for 35 to 40 minutes. Uncover and continue baking until the sweet potatoes are tender and the gratin is golden brown, another 15 to 20 minutes. Let rest for 15 minutes before serving.
