Variations for Baked Potato Mashed Potatoes
- This recipe calls for Russet potatoes, but it’s really up to you! Yukon Gold potatoes work great for this dish too, bringing extra buttery flavor to the dish.
- For a reduced-fat version, try Neufchâtel cheese in place of cream cheese, maintaining the creaminess with fewer calories.
- Play around with fresh herbs like chives, thyme, or rosemary to give your dish an added layer of aroma and freshness.
- Another great addition to twice baked mashed potatoes is sautéed onions or caramelized shallots because they add a sweet and savory depth.
- Roasted garlic and grated Parmesan cheese add even more delicious flavor that pairs beautifully with the creamy texture.

What Size Casserole Dish Should I Use?
This recipe works great in several sizes of casserole dishes, so there’s no right answer! I recommend using a 9×9-inch or 9×13-inch casserole dish for the serving size in the recipe.
If you use the smaller size, aim to cook your baked potato mashed potatoes closer to the 30 minute mark so the potatoes cook all the way through! If the potato layer is spread thinner in your casserole dish, shoot for 25 minutes instead.
What Is the Difference Between Baked Potatoes and Mashed Potatoes?
Traditionally, mashed potatoes are made from boiled potato pieces while baked potatoes are, well, baked!
No boiling is needed for baked potato mashed potatoes, but you will need to bake twice — first to soften the spuds, then again to heat the casserole and melt the cheese.
How Do I Reheat Leftover Twice Baked Mashed Potatoes?
If you’re looking to achieve that perfect reheated crispness and even warming, simply pop the dish in a preheated oven set to 350 degrees F. When they’re heated through (about 20 minutes) and the cheese is melted and gooey again, your potatoes are ready to enjoy!
For a quicker fix, you can reheat individual portions in the microwave. Heat in 30-second intervals until warmed through.
Leftovers will keep in the refrigerator for 4-5 days tightly covered with plastic wrap, foil, or a lid. I don’t recommend freezing as the overall texture will be grainy once thawed and reheated.
