Loaded Mashed Potato Bake (Leftover Mashed Potato Recipe) – With Video!

Looking for a leftover mashed potato recipe? This Loaded Mashed Potato Bake casserole is the most delicious way to use up leftover mashed potatoes. It’s loaded with bacon, cheese and sour cream!

Thanksgiving is one of my favorite holidays, but with a gathering of just six people, we’re often stuck with quite a bit of leftovers after the big meal, especially when it comes to turkey and mashed potatoes.

Even the smallest turkey feeds way more than six people, and for some reason, I find it impossible to make a small batch of mashed potatoes.

The question becomes, what to do with leftover mashed potatoes? While you can simply reheat leftover mashed potatoes, or even make mashed potato croquettes, my favorite way to serve leftover mashed potatoes a second time is this Loaded Mashed Potato Bake.

How long are leftover mashed potatoes good for in the fridge?

As long as they are refrigerated promptly (no more than 2 hours after serving), they will last about 3 or 4 days.

How do you reheat mashed potatoes?

My favorite way is to make baked mashed potatoes by simply placing them in a casserole dish, covering it with foil, and baking at 350 degrees F until they are completely heated through. And why not add some extra flavor before you reheat? That’s where this Loaded Mashed Potato Bake recipe comes in.

Tips for making this leftover mashed potato recipe successful

This recipe works great with leftover mashed potatoes (or even leftover blue cheese mashed potatoes), but you can also make it starting with fresh mashed potatoes (i.e. make mashed potatoes specifically in order to make this recipe). I

f using leftover mashed potatoes, the potatoes do need to be slightly warmed before stirring in the other ingredients. Cold mashed potatoes are very hard to stir and incorporate with the other ingredients.

These baked mashed potatoes are very adaptable to your family’s preferences and whatever ingredients you happen to have on hand. Omit the bacon for a vegetarian dish. Use chives instead of parsley. You can even use Parmesan cheese instead of cheddar!

What can you put in a leftover mashed potato recipe for flavor?

My favorite flavorings are the ones I’ve added to this leftover mashed potato recipe:

• sour cream
• garlic powder
• sharp cheddar cheese
• bacon
• green onion
• red onion
• parsley
• crushed cheese crackers on top!

Can I freeze this leftover mashed potato recipe?

If you make this recipe using leftover mashed potatoes, I do NOT advise freezing it and reheating it again. As a general rule of thumb for food safety, you only want to reheat leftovers once. Anything left over after that, you should discard.

However, if you make this recipe using “fresh” mashed potatoes (mashed potatoes you made immediately before making this casserole), you can freeze it.

Bake the frozen casserole straight from the freezer at 350 degrees F until the internal temperature of the casserole reaches at least 165 degrees F.
