How to make loaded Mashed Potato Casserole?
- Boil the potatoes: In a large pot, add some cold water. Bring to boil over medium-high heat. Then, add some salt and the spuds. Let the spuds boil until they become tender after about 15 to 20 minutes. Then, drain.
- Mash the spuds: Using a potato masher or electric mixer, mash the spuds to have an even consistency. Then, put them back in the pot.
- Season: Add the cream cheese along with the rest of the dairy ingredients. Season with salt and pepper to taste, and stir. At this point, stir in only a cup of cheese.
- Prepare for baking: Preheat the oven. Place the potato mixture into a baking pan, or casserole dish greased with cooking spray. Sprinkle the remaining cheese on top.
- Bake: Next, cover the pan with foil then pop it in the oven for about 20 minutes. Remove the foil and add the bacon. Bake it again until the cheese toppings become bubbly.
- Serve: Garnish with the chopped herbs and serve!
Recipe Variations and Substitutions:
- Add more veggies: Feel free to add more veggies to it. Some great addition would be broccoli florets, tomatoes, French onion rings, green beans, mushrooms, etc.
- Instant Pot: Alternatively, feel free to make this dish in the Instant Pot, here is the Instant Pot version.
- Swap the Cheese: Instead of cheddar, you can always use other types of cheese entirely, or a combination of a few. Gouda, parmesan cheese, Parmigiano, Asiago, Pepper Jack, Monterey jack cheese, Gruyere cheeses are great alternative. Also, feel free to mix it with cream cheese.
- Add proteins: To make it part of your main dishes, simply add some shredded chicken, rotisserie chicken, or sausage to it.
- Milk substitute: As a milk substitute, try using cream or creme fraiche.
- Toppings: Add more texture by topping it with a layer of panko crumbs, crushed crackers, or some crispy onion rings!
Can I make this recipe in the Slow Cooker?
Absolutely! Instead of cooking the spuds on the stovetop, you can easily make this Slow Cooker Mashed Potatoes recipe. This gives you an option to utilize other kitchen appliances to focus on other dishes that will require your stovetop.
This also becomes extremely helpful during the holidays, and a perfect dish to enjoy.
Best potatoes to use?
While I use russet here, other varieties work as well. For example, Yukon golds, King Edward have a creamy texture as well, making them a great alternative.

This hearty and comfort side dish goes well pretty much with anything meaty such as the following:
Can I make Mashed Potato Casserole ahead?
Yes! You can prepare this dish a day in advance. Just cook the potatoes and mash them. After that, place potatoes into a casserole dish. Cover and refrigerate overnight. When ready to bake the next day, simply pop it in the oven and add the topping ingredients.
Can I freeze it?
Yes, you can freeze it for months tightly covered.
To reheat, simply bake it in the oven for an extended period (about 10-15 minutes at 350 degrees F) to ensure that it is heated through.
More delicious side dishes:
- To add more crunch to it, bake uncovered during the last 5 minutes of cooking.
- To make it creamier, feel free to add 2 extra tablespoons of butter. The cheese butter combination is what turns this dish into a creamy potatoes meal.
- Out of russets? No problem! Then, use sweet potatoes.
- For extra flavor, add garlic powder, taco seasoning, or homemade ranch seasoning.
- Drizzle the top with gravy to make it even better!
- If you are using an electric mixer, I recommend using a large bowl or large mixing bowl. This way, the ingredients do not fly out.
