Twice Baked Potato Casserole Recipe
Last weekend we had an awful rainstorm, it felt like the sunny sky didn’t exist anymore!
It was one of those days where I felt so unmotivated and just wanted to watch Netflix. But I also need some comfort food. Like mashed potatoes and that’s where this recipe comes in.
This is a great way to use up leftover potatoes. Just like all my favorite dishes but in casserole form. Craving more potatoes? Check out Dickey’s potato casserole and mashed potato casserole.

Bacon is a classic, but don’t stop there! Some fun toppings to try are corn, cilantro, broccoli, chili, or meat!
How to Make Twice Baked Potato Casserole

How long does it last?
Keep any leftovers in the refrigerator, in an airtight container, for four to five days.

Serving Suggestions
This is a delicious side dish, a main dish if you want a meatless meal! As a side dish, serve it along with a rotisserie chicken, pork chops, or even meatloaf.
Tips for the Best Casserole
- You can use creamy or chunky potatoes. For more color, try Yukon gold or mini red potatoes and leave the skins on.
- Shred your own cheese. Store bought shredded cheese doesn’t melt as well.
- A potato masher makes the perfect consistency in my opinion!
- Avoid extra prep fuss and buy Pre-made mashed potato and precooked bacon or cooke the bacon and potatoes ahead of time.
- Make this in the slow cooker too!
- Serve your potato casserole with filling entrees like chicken, or crisp salad.
- Make and freeze in advance for up to two months to have an easy dinner ready ahead of time!
