Cheesy Mashed Potato Casserole

No more boring mashed potatoes! It is no big secret that more butter, more cheese and more sour cream turn a plain old potato into the star of the meal. Our Cheesy Mashed Potato Casserole is a perfect dish for family get-togethers, potlucks, or just a regular Tuesday night.

This recipe is inspired by my husband’s sweet aunt. I can’t remember it word for word, because she was telling me the recipe while we were eating it. My focus was on getting another forkful in my mouth. But I think I got it pretty close. Butter, sour cream, cheese. Yep! My kind of recipe from my kind of lady!

There are no special skills required. If you can hold a fork, you can make this cheesy and easy side dish!

Cheesy Mashed Potato Casserole…ultimate comfort food!

Cook up your mashed potatoes like you normally would. Cover with cold water and bring to a boil. Try to cut the potatoes into evenly sized pieces…but don’t sweat it if they aren’t.

Say no to boring mashed potatoes! Load your spuds up with delicious cheddar cheese, sour cream and oh-yeah butter, and give your meal a special side.

 

You want to make sure the potatoes drain well and dry. This will give you the best, fluffiest potatoes. After we drain ours, we toss them back into the warm cooking pan and place them on the stove top for a few minutes.

After you spread the potato mixture into a prepared casserole dish, sprinkle the top with the remaining cheddar cheese. (You can use any cheese, actually, we just love cheddar. Monterrey jack would be excellent…or pepper jack if you want to spice it up!)

Bake until delicious and bubbly. (Our Bacon & Green Bean Casserole would be a great companion for this dish! Or how about Honey Butter Carrots. Yum.)

There are very few things we love more than warm, melty and browned cheddar cheese. Especially on top of buttery, creamy mashed potatoes.

Talk about a splurge-worthy side dish, our Cheesy Mashed Potato Casserole is a hit with everyone.
