How to Make This Loaded Baked Potato Casserole Recipe

Ingredients in a large saucepan with a spatula and cheese on the side.

You’ll start this easy cheesy potato casserole by getting your oven ready and setting it to 350 degrees. While that warms up, prep your potatoes. If you don’t have Russet potatoes, just about any type of potato would work, like Yukon gold potatoes or red potatoes.

Wash, peel, and dice your potatoes and put them into a large pot with just enough water to keep them covered. You’ll add just a pinch of salt into the water and put it on the stovetop over high heat.

Let the potatoes come to a boil and become tender, which takes about 15 to 20 minutes. It’s easy to tell when they’re ready by piercing them with a fork. If they start breaking into small pieces, they’re ready for the next step!

Drain your potatoes well, and then pour them back into the now-empty pot. Mix in the mayonnaise, some of the bacon, and cheese, then stir it until it’s all well combined.

Pour this mixture into a 9 x 13-inch greased baking dish, then top it with the rest of the bacon and cheese. The hardest part is patience, as you’ll need to bake this for 30 minutes or until you see the cheese is all melty on top. It should also be completely warmed throughout.

When it’s ready, pull the casserole out of the oven and toss some green onions on top as a garnish before serving. You may also want to add your favorite potato toppings, like sour cream. You can also sprinkle a little bit more crispy bacon on top. 

Drizzle on some zesty ranch dip for added flavor.

Should Bacon Bits, Precooked Bacon, or Regular Bacon Be Used?

Using bacon bits or precooked bacon that you can heat up in the microwave will save you a lot of time, but if you prefer to cook the bacon beforehand, that will also work. Fresh, crispy bacon will taste the best.

Can Store-Bought Shredded Cheese Be Used?

Yes, it can, but it is better to shred your own if possible.  The freshly shredded cheese melts better.

What Type of Other Foods Can This Recipe Be Served With?

These loaded cheese potatoes pair well with a main dish such as ham, turkey, steak, or chicken. Green beans or sweet peas also work well as an additional side and dinner rolls for bread. This recipe works well as a side dish for large gatherings or as a holiday meal like Thanksgiving, Christmas, and Easter.

How To Store The Dish

Any leftover potatoes should be stored in the casserole dish with some plastic wrap on top or in a smaller, airtight container. You will need to refrigerate the leftovers, which are good for up to five days. 

Can The Recipe Be Frozen?

Yes, you can freeze this potato recipe before baking.  Simply remove from the freezer the night before to thaw and heat according to the directions.  It will last in the freezer for up to three months.

Optional Ingredients

  • Black pepper
  • Garlic powder
  • Minced onion
