Why This Sweet Potato Casserole is My Holiday Staple

Few dishes capture the essence of holiday comfort quite like this sweet potato casserole with marshmallows. For me, it’s the combination of silky, buttery sweet potatoes layered with golden, chewy marshmallows that wins every time. That top layer—ever so slightly crisp and caramelized—reminds me of those big family gatherings and the anticipation of diving into the buffet.

Sweet potato casserole is a crowd pleaser, and it’s always the first empty dish on the table. Whether it’s Thanksgiving, Friendsgiving, or just a proper Sunday dinner, this recipe nails that perfect balance between sweetness and comfort food satisfaction.

Here’s why I keep coming back to this dish:

  • The natural sweetness of the potatoes, only enhanced by a little brown sugar, lets the flavor shine without being overly sugary.
  • Spices like cinnamon and nutmeg add warmth and depth—I can’t skip these even for a classic.
  • The marshmallow topping isn’t just nostalgia—it creates this incredible contrast of textures that makes every bite interesting.

Pro tip: This casserole reheats beautifully and is even better as leftovers.

If you’re looking to impress with minimal effort at your next get-together or celebration, you can’t go wrong with this dish. It might just earn you the title of holiday legend.
