This savory sweet potato casserole is rich, comforting, and built for real flavor. Creamy sweet potatoes bake under a crispy topping of bacon and sharp cheddar for a dish that stands out.
Preheat oven to 400°Fahrenheit (200°Celsius), line a baking sheet, wash sweet potatoes, and prep bacon, cheese, onions, and egg.
Pierce and bake whole sweet potatoes about 1 hour until very tender, then cool slightly.
Scoop out the flesh and mash with a bit of texture.
Cook bacon until crisp, then drain and set aside.
Mix potatoes with half the bacon, onions, cheese, sour cream, egg, and seasoning, spread in a dish, top with remaining bacon and cheese, and bake 30–35 minutes until golden.
Notes
The bacon fat left in the skillet after crisping is full of flavor. If your mixture feels a little dry before you pour it into the baking dish, stir in a teaspoon of the rendered fat instead of adding more sour cream.
Smoked paprika is listed as a seasoning, but it is doing more than that here; it gives the casserole a subtle warmth that plain paprika does not. Worth using if you have it.
The casserole can be assembled the night before and refrigerated unbaked. Add the bacon and cheese topping just before it goes into the oven so they do not sink into the mixture overnight.
