Potato Stuffed Baked Onions

Total Time

A great side to roasts and BBQ's, especially in a buffet line or at a dinner party. They can be made a day ahead and heated in the oven before serving. Any unused mashed potatoes can be put in a casserole and refrigerated up to 10 days. Simply reheat in the oven when needed. The recipe is intentionally vague about ingredient quantities other than the mashed potato stuffing. Make as many or as few onions as you need. You can make large, dinner-sized onions or tiny appetizer onions. Prep time and yield will vary accordingly.

Wonderful flavor in this recipe!! Used Yukon gold potatoes and sweet onions. Made a bit of a change -substituted plain yogurt for sour cream. Then dusted the outside of the stuffed onions w/just a pinch of sage/poultry (Bell's)seasoning as we served these with pork chops. Ummm umm good!! (Next question...Do you think these would freeze well like twice baked potatoes? I'm going to try it sometime) Thanks soooo much for posting. These are a treat!!
