This is an easy casserole that is enjoyed year-round.  It’s a hearty and filling side dish for summer cookouts, potlucks and holiday meals.  I’ve made this casserole for years and it’s always a winner!

How I Came Up With This Recipe

Several years ago I had a couple of good friends to show up unexpectedly on a Sunday evening.  I had just finished grilling steaks and had 2 baked potatoes that had just come out of the oven.

I wanted them to stay for dinner, so I put the baked potatoes in a big bowl, chopped them up and added butter, sour cream, shredded cheese, mushrooms, sliced green onion, bacon pieces, salt and pepper.  I combined all of the ingredients, transferred it to a casserole dish and baked until the cheese melted.

It was such a hit that I’ve been making it ever since and always get asked to bring it when a side dish is needed for a potluck or cookout.

Why I Bake Potatoes In Foil For This Recipe

Baking the potatoes in aluminum foil keeps the skin soft and the potato moister inside, which allows for the potato skin to be included in the casserole.

How to Make This Baked Potato Casserole Ahead of Time

Cover and refrigerate the casserole until it’s ready to be baked.  Remove from the fridge and allow to come close to room temperature before baking.

There’s nothing more comforting than buttery, creamy potatoes surrounded by melted cheese, bacon pieces, mushrooms and green onions.  I eat leftovers for breakfast (if there are any leftovers!).  It’s that good.
