Expert Tips That I Recommend
- Bake sweet potatoes instead of boiling, as baking concentrates their natural sweetness and prevents excess moisture, resulting in a richer, thicker base.Â
- Layer topping evenly without pressing it down. Lightly sprinkle the topping so it crisps rather than becoming dense or soggy during baking.
- Let the casserole rest before serving. Resting helps it set properly, making it easier to slice and enhancing overall flavor.
