It’s always hard to be motivated to cook when you are tired and hungry. That is why casserole recipes are the perfect solution. Easy to make, you can often prepare them ahead of time.

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

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.
