RECIPE: Onion Mashed Potato Casserole

Sharing is caring!

Onion Mashed Potato Casserole is a recipe of cheesy, onion, goodness that everyone is sure to love!  This can be made with real potatoes or you can alter the recipe a bit to use boxed mashed potatoes instead.  Either way, it is a delicious and filling side dish that is perfect for any meal.

Just a tidbit of advice here:  If you have picky kids, be aware – this stuff doesn’t look all that great because the Lipton turns the potatoes into a tan/brown color.  However, once I convinced my boys that it was really good, they LOVED it. 🙂  We like to serve this with Saucy Parmesan Chicken, the flavors compliment each other very well!


Psst: I just love the small candy/trifle bowl that I found at Goodwill. 🙂
