I’m sure you’ve had your fair share of baked potatoes, mashed potatoes and french fries over the years. But I think this will quickly become one of your favorite recipes after you try it.

Twice Baked Potato Casserole

I’ve heard this recipe called a twice baked potato casserole. But since I boiled the potatoes rather than bake them before adding the other ingredients, I’m using the word “loaded” rather than “twice.” It’s only baked once.

However, I do have this twice baked potato recipe that’s super delicious. It’s similar, but it’s not in casserole form.

Perfect for Any Occasion

This loaded baked potato casserole recipe is a great way to change up your potato routine and it’s perfect for any occasion!

Bring one of these delicious casseroles to your next potluck or get-together with friends. Everyone will want your recipe.

I like to make this for family dinners. It’s the perfect side dish because it’s filling, comforting, and so delicious! 

You’ll be delighted when this becomes a family favorite side dish. Serve it on a weeknight, at your Sunday dinner, or save it for a special Thanksgiving dinner side.

Ingredients

All of the ingredients for a loaded baked potato casserole can be found in most grocery stores. And there’s a good chance that you already have some of the items in your fridge and pantry.

Here is what you’ll need:

  • Butter (or olive oil if you prefer)
  • Cream cheese
  • Shredded cheddar cheese
  • Sour cream
  • Milk (or heavy cream for a richer flavor)
  • Onion powder
  • Garlic powder
  • Minced white or yellow onions

I like to use whatever type of potato I have on hand. You can use russet potatoes, Yukon gold potatoes, red potatoes, or whatever you prefer.

Since I was out of bacon, I used a package of bacon bits that I keep on hand for times like this. There are so many other great flavors in the casserole, it’s hard to tell the difference.

Additional Options

You can either bake the potatoes first or boil them in a large pot. I prefer the boiling method because there is more moisture in the potatoes.

It’s up to you whether you want to peel the potatoes or leave their skins on. Potato skins add color and extra nutrients. For this recipe, I used some of the skins but not all.

You can use any type of milk you have on hand. I’ve used whole milk, almond milk, and low-fat milk. There’s only a slight difference in the taste. 

However, cream adds a richer flavor, so I highly recommend using that you have it.

If you like extra spicy heat in your food, you can also add a dash or two of hot sauce or cayenne.

I also like to use sharp cheddar cheese to add even more flavor. However, you can use any type of shredded cheese you happen to have in your fridge. We keep plenty of cheddar cheese around for times like this.

If you like additional potato toppings, go ahead and add them. This is your casserole, so make it the way you like it.

If you’re cooking for a large crowd, you can double this recipe and use a large baking dish.

How to Make a Loaded Baked Potato Casserole

Heat oven to 375 degrees F. Spray a 7” x 11” baking pan with nonstick cooking spray.

Put potatoes, butter (or olive oil, and cream cheese in a large bowl. Mash them with a potato masher. I like to keep these mashed potatoes lumpy because I prefer more texture, but that’s up to you.

Pour in the milk and stir.

Add the sour cream, onion powder, garlic powder, minced onions, half of the bacon, half of the shredded cheddar cheese, and salt and pepper.


Mix all of the ingredients and spoon mixture into the baking pan. Sprinkle the remaining shredded cheddar cheese, bacon pieces and parsley over the top.

If you want more crunch, you can sprinkle breadcrumbs over the top.


Bake for 30 to 40 minutes or until the cheese has melted. If you added breadcrumbs, they should turn golden brown.

Common Questions About Baked Potato Casserole

There are so many good things about this delicious side dish (or main dish if that’s how you roll) that you’re bound to have some questions. And I have some answers!

Q: How Long Does a Loaded Baked Potato Casserole Keep?

A: A baked potato casserole will last in the fridge for up to four days or in the freezer for up to two months. Cover the baking dish with plastic wrap before refrigerating it. If you freeze it, make sure it’s in an airtight container. 

Make sure to reheat it before serving your leftover potato casserole. You can add more cheese on top if you like before putting it in the oven. There’s just something special about a gooey cheese topping.

Q: What kind of potatoes should you use for this recipe? 

A: Any type of potato will work for this recipe. I typically use whatever potatoes I have in my pantry.

You can even use sweet potatoes if you want to increase the nutritional value of this dish. They are a great source of fiber and nutrients, plus they have a very low glycemic index, which means you won’t get an insulin spike after eating them like you would with regular potatoes.

Q: Is this casserole gluten free? 

A: This version of baked potato casserole is gluten-free. If you add flour for thickening or breadcrumbs to the topping, it won’t be gluten free. 

However, you can easily make your own breadcrumbs from gluten-free bread. And I don’t think it needs to be thickened.
