Step 1: Preheat oven to 375 degrees.

Step 4: Add potatoes and 3 tablespoons maple syrup, 2 tablespoons butter, and the salt; stir.
Step 5: Preheat broiler.
Step 6: Spray six (broiler proof) 1-cup gratin dishes or one (broiler proof) 6-cup baking dish with cooking spray.
Step 7: Spoon sweet potato mixture into dishes, and smooth tops. Drizzle with remaining maple syrup. Dot with remaining butter.
Step 8: Broil until tops are sizzling and browned, 3 to 4 minutes.
