Add onions, thyme, honey and 1/4 tsp. salt; cook until onions are softened, 5 to 7 minutes; remove thyme. Melt the remaining 2 Tbsp. butter in a large saucepan over medium heat. Add flour and cook 1 minute. Slowly whisk in cream and broth, bring to a simmer, and cook until thickened, about 2 minutes. Stir in 2 Tbsp. chives, 3/4 tsp. salt and 1/4 tsp. pepper. Spread half of the sauce into prepared baking dish. Shingle half of the potatoes in baking dish, sprinkle with 3/4 C. Gruyere and half of the onions. Repeat with remaining potatoes, cheese and onions. Pour remaining sauce over the top and press slightly with a spatula to compact. Cover dish with aluminum foil that has been sprayed with cooking spray. Bake for 1 hour. Uncover and continue to bake for about an hour longer. Let the casserole cool 10 minutes, and then sprinkle with remaining 1 Tbsp. chives. Serves 8. |
