FAQ’s About This Recipe

Why Are The Potatoes Called “Loaded”?

Because this recipe comes with all kinds of toppings, the term loaded means just that.

What Are The Best Potatoes To Use In This Recipe?

There are so many potatoes out there that you can use for this recipe. However, because of starch content, russet potatoes tend to produce a creamier result when mashed, so that is my favorite. Idaho potatoes are also a great choice.

Is Warm Or Cold Milk Best When Making This Recipe?

My grandmother always used warm milk when she made her potatoes, so that is what I use. Cold milk can end up curdling or separating because of the difference in temperatures.

Is There A Way To Make The Mashed Potatoes Creamier?

My secret ingredient to use in potatoes to make them creamier is heavy whipping cream. I use it as a substitute for milk in a lot of my recipes now and it really makes a difference.

What To Do With Leftovers: Storage & Reheating Tips

If you happen to have leftovers after making this recipe for loaded mashed potato casserole, what next?

What Is The Best Way To Store Any Loaded Mashed Potato Casserole Leftovers?

Always store your leftovers in airtight containers, making sure the casserole is completely cooled before placing in the fridge or freezer.

How Long Can Leftovers Be Stored In The Fridge?

You can store any of the leftovers in the fridge for about 3-4 days.

Can The Breakfast Casserole Be Frozen?

Because of the milk or heavy cream you use in this recipe, I don’t recommend freezing this dish for future use. The layers will crystalize and separate when thawing.

To reheat in the microwave, cover individual servings with a microwave-safe lid or paper towel (I always suggest wetting the paper towel), microwave for 60 seconds, check your temperature, then microwave for 20 seconds more, if necessary.
