Peel sweet potatoes and chunk.
Place sweet potatoes in a large kettle or stock pot; cover with water.
Add a half teaspoon of salt.
Cover with lid and bring sweet potatoes to a boil.
Boil sweet potatoes until tender – about 15-20 minutes.
Drain sweet potatoes in colander and transfer back to the stockpot.
Mash sweet potatoes with a potato masher until smooth.
Meanwhile, in a small saucepan, cook and stir the butter, cheddar cheese, half-and-half and remaining teaspoon of salt until smooth.
Add black pepper, 1 tsp. fresh, minced parsley and ½ tsp. fresh, minced chives (or you can add more seasonings, if desired)
Remove from heat; set aside.
Once sweet potatoes are mashed, stir cheese mixture into the drained, mashed sweet potatoes.
Fold beaten eggs into the sweet potato mixture.
Pour mixture into a greased 3-qt. casserole dish.
Bake, uncovered, at 375° for 35-40 minutes or until puffy and golden brown.
Sprinkle with fresh chives, and additional parsley, if desired.
