This Loaded Mashed Potato Casserole is my cozy spin on a classic comfort dish and it is rich warming and made for sharing whether it is a busy weeknight or a special gathering and it brings that familiar creamy feeling right to the table while still feeling a little extra thanks to all the layers of flavor and texture inside.

My Loaded Mashed Potato Casserole recipe begins with soft fluffy potatoes that are mixed with creamy elements and savory add ins then gently baked until everything comes together into one satisfying dish and every bite feels indulgent comforting and worth slowing down for.

Ingredients

Here is what I use for this recipe and you can always adjust based on what you love most.

Potatoes: The hearty base that creates the fluffy and comforting structure of the casserole.
Sour cream: Adds tanginess and creaminess that keeps the potatoes moist.
Cream cheese: Brings richness and a smooth texture that makes the mash extra luxurious.
Butter: Enhances flavor and helps everything melt together beautifully.
Cheddar cheese: Gives that classic sharp cheesy bite throughout the dish.
Green onions: Add freshness and a mild onion flavor that balances the richness.
Red onion: Provides a subtle crunch and deeper savory note.
Cooked bacon: Adds smoky salty bites that make the casserole feel loaded and indulgent.
Fresh herbs: Brighten the overall flavor and add color.
Black pepper: Brings gentle heat and rounds out the seasoning.
Salt: Enhances all the flavors and keeps the potatoes from tasting flat.

Tools You’ll Need

Large pot: Used to boil the potatoes until they are tender and easy to mash.
Colander: Helps drain the potatoes thoroughly so the mash is not watery.
Large mixing bowl: Allows enough space to combine all ingredients evenly.
Potato masher: Creates the perfect mashed texture without overworking the potatoes.
Wooden spoon or spatula: Helps gently fold in the mix ins.
Baking dish: Holds the casserole and allows it to bake evenly.
Oven: Brings everything together with heat and creates a lightly golden top.

Instructions

Step 1: Prepare the Potatoes

I start by peeling and cutting the potatoes into even chunks then I boil them in salted water until they are fork tender and this step is key because evenly cooked potatoes mash more smoothly and give the best texture.

Step 2: Drain and Mash

Once the potatoes are soft I drain them well and transfer them to a large bowl then I mash them while they are still warm because warm potatoes absorb butter and cream much better.

Step 3: Add the Creamy Ingredients

I mix in the butter cream cheese and sour cream while the potatoes are hot and I stir gently until everything melts together and becomes smooth and creamy without overmixing.

Step 4: Season and Mix In

I season the mash with salt and black pepper then I fold in shredded cheddar cheese green onions red onion bacon and fresh herbs and I make sure everything is evenly distributed.

Step 5: Assemble the Casserole

I lightly grease a baking dish and spread the potato mixture evenly inside then I smooth the top with a spatula so it bakes evenly.

Step 6: Add the Topping

I sprinkle extra cheddar cheese and bacon over the top because this creates a flavorful crust that makes the casserole look and taste irresistible.

Step 7: Bake

I bake the casserole in a preheated oven until it is hot throughout and lightly golden on top and the aroma alone tells you it is ready.

Step 8: Rest and Serve

I let the casserole rest for a few minutes after baking so it sets slightly which makes serving easier and keeps the texture perfect.

Tips

When I want extra creamy potatoes I add a splash of warm milk while mashing and if I want more texture I leave a few small potato chunks instead of mashing completely and for a deeper flavor I sometimes mix in roasted garlic or swap cheddar for a blend of cheeses.

Ways to Serve

I love serving this Loaded Mashed Potato Casserole alongside roasted meats grilled chicken or holiday mains because it pairs beautifully with savory proteins and it also works well as a standalone dish with a fresh green salad when I want something comforting but simple.

Storage Instructions

I store leftovers in an airtight container in the refrigerator and they keep well for several days and when reheating I cover the dish and warm it slowly so the potatoes stay moist and creamy and if needed I add a small spoon of sour cream before reheating.
