Cheese does not melt or brown
Increase the oven temperature to 425°F for the last 5 minutes or place under the broiler briefly, watching closely.
Egg mixture looks watery
Make sure the baked potatoes are well‑mashed and excess moisture is removed; you can also add a tablespoon of flour to help bind.
Storage
Refrigerator: Store leftovers in an airtight container for up to 3 days.
Freezer: Not recommended; texture may become watery after freezing.

Make-Ahead Tips
- Bake the sweet potatoes a day ahead, store them peeled and mashed in the fridge, then add eggs and cheese and finish the second bake when ready to serve.
