Ingredients in the Twice Baked Potato Casserole Recipe…

The best thing about this recipe are the simple ingredients it uses! I bet you already have almost everything in your fridge or pantry to make this delectable dish!!

Russet potatoes, bacon, milk, sour cream, butter, cheddar cheese, a couple green onions (chives work too!), a little oil, season salt, and salt & pepper. That’s it!

Simple, right??

Preparing the Recipe…

Preheat your oven to 400 degrees.

Scrub the potatoes clean, and rub them with a little canola oil. Place them on baking sheet, and bake about 40-50 minutes. I usually poke a sharp knife in them to test doneness. You want them to be baked soft.

You can bake up the potatoes the day before. And store them in the fridge until you’re ready to assemble the casserole.

While the potatoes are baking, fry up the bacon. Crumble it.


Take out your milk, butter, and sour cream to allow it to warm a bit. If you forget to do this, don’t worry. Put these dairy items into a microwaveable dish and pop them in the micro for about 45 seconds.

Leave the skin on two of the baked potatoes, and peel the others. Cut potatoes into thirds and place in a large bowl.

adding dairy ingredients to baked potatoes

Add warmed butter, milk, and sour cream to potatoes. Also add in one cup of the cheddar cheese, half of the bacon, the season salt, and the salt & pepper. Mash away until creamy!!

Place in a greased casserole dish, and bake at 350 degrees for about 25 minutes. Add more of the shredded cheddar cheese and crumbled bacon to the top of the potatoes. Bake until the cheese is all melty and dreamy!

If you need oven space for something else, you could also heat this recipe in the slow cooker on low for 2 hours or on high for 1 hour.

Top the baked casserole with the green onions or chives.
