Recipe Notes

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.

What kind of potatoes are best for twice baked potato casserole?

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.

Can I make this casserole ahead of time?

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.

Can I use pre-made mashed potatoes?

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.

How can I make a vegetarian version?

For a vegetarian twice baked potato casserole, simply omit the bacon – no other changes needed.

Can I use any kind of cheese?

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.

Can I double this recipe?

Yes! To serve a crowd (16-20 people), simply double all of the ingredients and bake in a 3-quart baking dish.

Serving Suggestions

Here are just a few of my favorite entrees to serve alongside this easy side dish!

Tips!

When it comes to bacon, you can never have too much. Measure it with your heart!
Don’t forget to remove the foil at the end! The cheese is so tasty on top from those last few minutes of baking without foil.
Use a full fat, not low fat sour cream for the most dense results.

Of all the ways to use up a few plain russet potatoes, this has got to be the most satisfying!

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.
