My dad loves Vidalia onions and I made this for Father's Day. We all thought it was delicious but he was especially pleased. The onions carmelized well and had extraordinary flavor that was perfect with the mashed potatoes. A nice side dish that would go with many things. Thank you Diggy.

I had 3 large baking potatoes that were in the "use or toss" mode. So I tried this recipe. I figured you can't go wrong with mashed potatoes, caramelized onions and cheese. Everyone loved it and requested that it be made again. . . soon. It was so easy and delicious.

loved the flavor of the caramelized onions in the mashers!! it's this sweet, almost red wine-like flavor! i used roasted garlic instant mashed potatoes and skipped the cheese. made this early in the day, then baked at dinnertime! thanks for posting, this was fantastic!
