Loaded Baked Potato Casserole is a delicious side dish. It is stunning to look at and fabulous to eat.
This Loaded Mashed Potato Casserole recipe has it all. It’s creamy. It’s rich. It’s decadent. It’s loaded with bacon. It needs to be on my plate now!
This is one of those recipes that seems like it should be reserved for Sunday supper. But, lo and behold, it’s easy enough for busy weeknights. The secret weapon for this recipe is instant mashed potatoes. There’s no peeling. No boiling. No mashing.
You can prep the entire thing ahead of time (or the night before) and stash it in the fridge until you’re ready. Then, about 30 minutes before dinner, just pop the casserole in the oven.
My family could not get enough of this. I think my husband even had thirds. And, no one believed that I used instant mashed potatoes.
Instant mashed potatoes are a great culinary secret weapon. I use them in my American Pierogi recipe – it’s one of those times where instant mashed potatoes actually work better than real ones. You can also use them to thicken soups and stews. They’re really a pantry must-have.
I use instant mashed potatoes for this recipe. They taste as good as if you peeled, boiled, and mashed them yourself. But you didn’t. It can be our little secret. I’ll never tell.
Oh, and you might want to write this super easy recipe down (or print it out below) because you WILL be asked for it. That’s a given!
