Cheesy Mashed Potato Casserole
Creamy, cheesy and delicious! This Cheesy Mashed Potato Casserole is a wonderful side dish for all kinds of dinners. Feel free to add crispy, crumbled bacon and green onions on top!
I loved this side dish. I had one change to the recipe, only because I misread the instructions. I had added the shredded cheese to the mashed potato mixture, instead of reserving it for the top. I quickly grated some extra Monterey Jack to add to the top. Because of this, I had extra cheesy potatoes but as you might guess, nobody minded.
We used Monterey Jack, but you can change the cheese if you’d prefer. I would highly suggest grating the cheese yourself, as it lends itself to melted much better than pre-grated cheese sold in a bag. Many thanks to The Southern Lady Cooks for this recipe. Enjoy!

Can you make ahead?
I'm not sure Kim. I would think you can but I haven't tested it.
