Potato Stuffed Baked Onions

READY IN: 1hr 20mins
Recipe by sugarpea

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.

Wow, were these ever great Sugarpea!!...I used large Vidalia onions for these, and also I added some fresh minced garlic and 2 Tbsp grated Parmesan cheese into the mashed potato/cream mixture otherwise made as directed. We had these with grilled T-Bone steak...a match made in heaven LOL!!..yummmmmmm...I can't wait to make these again, I will make lots next time and freeze them.... thanks SO much Sugarpea for sharing such a winning recipe, we all loved these!....Kittencal
