This make-ahead twice baked potato casserole delivers all the creamy, cheesy, bacony goodness of twice-baked potatoes without the fuss of individual servings. Perfect for holidays, potlucks, or busy weeknights, it can be assembled up to two days ahead and baked when you’re ready.
For best texture, ensure potatoes are fully baked and still warm when mashed. Shred cheese from a block for smoother melting. Let casserole rest after baking to allow filling to set. For a vegetarian version, omit bacon and add ½ cup extra cheese or sautéed mushrooms. For dairy-free, use plant-based alternatives (texture will be slightly less creamy).
