I found this recipe at Food Cloud.com.
If you are looking for something to make with leftover mashed potatoes or if you want to make something a bit different from just a side of mashed potatoes with gravy, you need to try these. These are excellent for serving at a dinner party!
2 cups firm mashed potatoes
3 large eggs, beaten
5 slices of bacon, fried and crumbled
2 chives or green onions, finely cut
1 cup sharp cheddar cheese, shredded
1/2 cup Parmesan cheese, shredded (not the green can kind)
1 tablespoon parsley flakes
1/2 teaspoon pepper
1 teaspoon garlic powder
dash of salt
Sour cream for garnishing
Preheat oven to 400 degrees. Spray 12 muffin cups with cooking spray. In a large mixing bowl, add potatoes, eggs, bacon crumbles, chives/green onions, cheeses, parsley flakes, and seasonings. Mix well. Spoon into the muffin cups. They will puff a bit so don't fill to the top but close. You can also sprinkle a little Parmesan cheese on the top of each prior to putting oven. Bake for 30-35 minutes or until golden brown. Serve with a dollop of sour cream if you like.
NOTE: Leftover mashed potatoes seem to work better in this recipe than freshly made. I just take the leftovers out of the fridge and let the come to room temperature (about 15 minutes).
