- Yukon Gold potatoes (5 lbs.): These offer a buttery texture, perfect for mashing and holding all those flavors.
- Kosher salt (1 tbsp, divided): Enhances the flavors and seasons the potatoes perfectly—don’t underestimate its power!

- Granulated onion (1 tsp): Brings a subtle sweetness and depth to the seasoning mix.
- Garlic powder (½ tsp): A little garlic goes a long way in pairing beautifully with cheesy and savory notes.
- Unsalted butter (½ cup, room temperature): Adds richness and a silky texture to the potatoes.
- Cream cheese (4 oz., room temperature): Gives the mash that velvety creaminess and tang that’s impossible to resist.
- Sour cream (1 cup): Brightens the dish and makes it wonderfully creamy and tender.
- Half-and-half or heavy cream (1½ cups, warmed slightly): Lightens the texture and keeps the potatoes luscious and smooth.
- Shredded cheddar cheese (2 cups, divided): Sharp and melty cheddar creates that classic cheesy goodness inside and on top.

How to Make Loaded Mashed Potato Casserole Recipe
Step 1: Prepare Your Casserole Dish
Start by giving your 9×13-inch casserole dish a quick spray with nonstick spray. This simple step makes sure your cheesy, creamy masterpiece won’t stick and will be easy to serve when dinner time arrives.
Step 2: Cook the Potatoes
Peel your Yukon Gold potatoes and chop them into 1-inch cubes to ensure even cooking. Place them in a large pot or Dutch oven with about an inch of water, and add some seasoning—2 teaspoons kosher salt, 1 teaspoon ground black pepper, 1 teaspoon granulated onion, and ½ teaspoon garlic powder. Bring the pot to a boil over high heat, then reduce to low and let the potatoes simmer until fork tender, about 15 minutes. This seasoning step helps infuse the potatoes with delicious savory notes right from the start.
Step 3: Drain and Dry the Potatoes
Drain the cooked potatoes well, then return them to the hot empty pot. Place the pot back on low heat for about a minute, allowing any excess moisture to evaporate. This trick ensures your mashed potatoes won’t turn out watery and will have that perfect fluffy texture.
Step 4: Mash and Mix the Ingredients
Now for the fun part: mash the potatoes until smooth. Add your softened butter, cream cheese, sour cream, and warmed half-and-half. Stir in 1 cup of shredded cheddar cheese, half the bacon, and 1 tablespoon of chopped chives. Give it all a good mix to combine everything evenly—this creates that iconic layered flavor and texture the Loaded Mashed Potato Casserole Recipe is famous for. Taste and adjust seasoning with salt and pepper if needed.
Step 5: Assemble and Bake
Spread the creamy, cheesy potato mixture evenly into your prepared casserole dish. Sprinkle the remaining shredded cheddar cheese and crumbled bacon on top. Bake in a preheated oven at 350°F (175°C) for about 25 minutes, or until the top is beautifully golden and bubbly. This final bake melts the cheese perfectly and locks in all the flavor.

Garnishes
Fresh chopped chives or green onions add a bright, fresh pop of color and flavor that contrasts beautifully with the rich, creamy casserole. If you’re feeling adventurous, a dollop of sour cream or a sprinkle of crispy fried onions on top can add an irresistible finishing touch.
Side Dishes
This casserole pairs wonderfully with a variety of main dishes. Think roasted chicken, grilled steak, or even a hearty vegetarian loaf. A crisp green salad or steamed greens complement the richness perfectly and add much-needed balance to your plate.
Creative Ways to Present
For a fun twist, consider serving the casserole in individual ramekins or baking it in a shallow cast-iron skillet for a rustic vibe. You can also top each serving with extra crispy bacon or a drizzle of warm gravy for an extra indulgent meal experience.
Make Ahead and Storage
Storing Leftovers
Your leftovers can be stored covered in the refrigerator for up to four days. Be sure to cool the casserole to room temperature before refrigerating, then cover it tightly with foil or plastic wrap to keep it moist and delicious.
Freezing
This Loaded Mashed Potato Casserole Recipe freezes quite well! Place cooled portions into airtight containers or freezer bags, and freeze for up to two months. When you’re ready to enjoy, thaw in the fridge overnight before reheating.
Reheating
To reheat, place portions in a preheated oven at 350°F (175°C) until warmed through, usually 20-25 minutes. You can also microwave individual servings, but be sure to cover loosely to retain moisture and prevent drying out.
FAQs
Can I use Russet or Idaho potatoes instead of Yukon Gold?
Absolutely! Russet and Idaho potatoes are great alternatives. They tend to be starchier and will create a fluffier texture, but Yukon Gold gives the best creamy, buttery consistency.
Is it possible to make this casserole vegetarian?
Yes! Simply omit the bacon and substitute with sautéed mushrooms or caramelized onions for a delicious vegetarian-friendly version without sacrificing flavor.
Can I prepare this casserole ahead of time?
Definitely. You can prepare and assemble the casserole the day before, cover it, and refrigerate until ready to bake. Just add a few extra minutes to the baking time if baking from cold.
What can I use instead of sour cream?
Greek yogurt is a fantastic substitute if you want a slightly tangier but equally creamy option. Just use the same amount as the sour cream called for in the recipe.
How do I get a crispy cheese topping?
Using sharp cheddar and baking the casserole uncovered allows the cheese to brown nicely. For extra crunch, sprinkle some crushed potato chips or fried onions on top during the last 5 minutes of baking.
