Ultimate Grilled Sweet Potato Casserole Recipe for Summer BBQ

Grilled Sweet Potato Casserole makes a flavorful, easy side for holiday dinners or weeknight meals. Whole sweet potatoes can be cooked on the grill alongside your main dish, then mashed with butter and brown sugar and finished with crisp bacon and chopped pecans for a savory-sweet casserole without marshmallows.

This version pairs beautifully with grilled ham, turkey, or pork chops and offers a smoky depth from the grill plus a satisfying mix of textures from creamy potatoes to crunchy pecans and bacon.
