Baking the potatoes in their skins allows their natural sugars to caramelize for enhanced sweetness.
Line an 8-inch-square baking dish with foil.
Prick sweet potatoes with a fork in several places, then transfer to the pan.
Bake until tender, about 60 minutes.
Set aside to cool, about 20 minutes.
Reduce oven temperature to 375F.
Peel and mash the sweet potatoes.
Remove the foil from the baking dish and coat the pan with cooking spray.
Beat with an electric mixer on medium speed until smooth.
Spoon into the prepared baking dish.
Combine oats, brown sugar, butter, and pecans; mix with your fingertips until crumbly.
Sprinkle the topping over the sweet potato mixture.
Bake until the casserole is heated through and the topping is brown, about 35 minutes.
Assemble the casserole through Step 3 up to 1 day ahead and refrigerate.
