- Toast the pecans lightly in a dry skillet for a nuttier flavor.
- Use pure vanilla extract for the best aroma; imitation can taste harsh.
Troubleshooting
Casserole is dry after baking.
Add an extra tablespoon of butter or a splash of milk to the mashed potatoes before spreading.
Marshmallows burn before the center is hot.
Cover the dish loosely with foil for the first 10 minutes of baking, then uncover to brown the marshmallows.
Sweet potatoes are lumpy.
Mash while the potatoes are still hot and use a potato masher or hand mixer for a smoother consistency.
