BBQ sweet potato and apple casserole is a unique dessert that combines grilled slices of sweet potato and apples. It is then topped with a pecan crumble.

Instead of a savory mixture like a gratin with cheese, this dessert dish is layered with a syrup and cream mixture, which keeps the dish moist and rich. It also nicely balances the tart apples.

Choose firm, sweet-tart baking apples for this dish, so they don’t fall apart on the grill or while baking. Although the sweet potato sounds like a savory ingredient it actually balances well in the final dish and is more of a neutral filler.
