How to Make Twice Baked Potato Casserole
You can jump to the recipe card for full ingredients & instructions!
- Preheat your oven and prepare a baking dish.
- Mash the potatoes, and stir in the ingredients.
- Spread potato mixture in a baking dish.
- Bake with foil, then without.
- Garnish, serve, and enjoy!
- If you’d like to use turkey bacon instead, that works too! Just make sure it’s cooked to a crumble like consistency before mixing it in with the other ingredients.
- For best results, always grate your own cheese. It makes a huge difference!
- Removing the foil at the end of the bake time makes the cheese perfectly bubbly and golden.
I love using russet potatoes for this casserole recipe. They’re typically what I choose for classic baked potatoes and mash and bake perfectly. Instead of russet potatoes, Yukon gold potatoes are great alternative.
Yes! Prepare the casserole through step 5. Cover tightly and refrigerate for up to 24 hours. When ready to bake, remove from the refrigerator and continue with step 6. Because the casserole mixture will be cold, it may need a few minutes longer in the oven to heat all the way through.
While freshly prepared mashed potatoes are best, you can certainly use pre-made (or leftover) mashed potatoes in this casserole recipe. Skip step 2, use about 4 cups of mashed potatoes and continue with the recipe in step 3.
For a vegetarian twice baked potato casserole, simply omit the bacon – no other changes needed.
Definitely. Use 2 cups of your favorite kind of shredded cheese. For best results, use block cheese and grate it yourself – pre-shredded cheese doesn’t melt as well as freshly shredded cheese.
Yes! To serve a crowd (16-20 people), simply double all of the ingredients and bake in a 3-quart baking dish.

What can I use if I don’t have a potato masher?
If you don’t have a potato masher, use a hand or stand mixer to mash the potatoes.
What can I use in place of sour cream?
Instead of sour cream, use the same amount of plain Greek yogurt. It’s just as creamy and tangy!
Can I make this recipe with sweet potatoes?
This twice baked potato casserole would be delicious with baked sweet potatoes. Swap russet potatoes for baked sweet potatoes and continue with the recipe as written.
