This was super easy and a great way to use mashed potatoes left over from another meal. I didn't care for the texture of the baked in onion rings but DH really did. We used fat free milk and fat free sour cream with no adverse taste or texture. Thanks Kitten for a recipe I will make again.
Delicious! For those who like exact ingredient amounts, I used 2 large potatoes, 2 tb butter, 4 tb milk, and the 3 oz container of onion rings. It's the perfect size for 3 side servings. Thanks for sharing the recipe!
