Putting together this delicious Loaded Mashed Potato Casserole Recipe is straightforward because it uses classic, easy-to-find ingredients that come together beautifully.

• 4 cups mashed potatoes: Use leftover or freshly made for a smooth, creamy base that forms the heart of the casserole.
• 1 cup shredded cheddar cheese: Sharp and melty, this adds cheesy richness and a golden topping.
• 4 slices cooked bacon, crumbled: Crispy bits of smoky bacon introduce texture and savory depth.
• 1/2 cup sour cream: Gives the potatoes a subtle tang and extra creaminess that balances the cheese and bacon.
• 1/4 cup milk or cream: Keeps the casserole luscious and perfectly moist throughout baking.
• 2 tbsp butter, melted: Adds buttery flavor and helps create a silky mashed potato consistency.
• Salt & pepper to taste: Essential seasonings that bring out all the flavors.
• 2 green onions, sliced: Fresh green onions add a pop of color and a mild onion bite as a garnish.

How to Make Loaded Mashed Potato Casserole Recipe

Step 1: Preheat and Prepare Your Ingredients

Start by preheating your oven to 350°F (175°C). This ensures that it’s hot and ready when you’re done assembling your casserole. Having your mashed potatoes and other ingredients measured out and ready to mix will streamline the process perfectly.

Step 2: Mix the Potatoes with Creamy Goodness

In a large bowl, combine the mashed potatoes with sour cream, milk or cream, melted butter, salt, and pepper. This step is where the magic happens—the sour cream and butter make the potatoes super creamy and rich, while the milk loosens the texture just enough to make it bake beautifully.

Step 3: Spread the Mixture Evenly

Transfer the mashed potato mixture into your chosen baking dish, spreading it out evenly. This creates a smooth, flat surface to hold the toppings and ensures even baking. Don’t be shy—get it spread nicely so every bite is consistent.

Step 4: Add Cheese and Bacon

Sprinkle the shredded cheddar cheese generously over the top of the potato layer, then scatter the crispy bacon crumbles all over. This combination promises gooey, melty cheese and bursts of intense smoky bacon flavor with every forkful.

Step 5: Bake Until Hot and Bubbly

Pop your casserole in the oven and bake for 20 to 25 minutes. You want to see the cheese melted and slightly golden, with the entire dish hot and bubbling. This step brings everything together into one irresistibly cohesive dish.

Step 6: Garnish and Serve

Once out of the oven, sprinkle the sliced green onions over the top while the casserole is still warm. These fresh onions add a beautiful finish and subtle crunch that complements the creamy potatoes perfectly.

How to Serve Loaded Mashed Potato Casserole Recipe

Garnishes

While green onions are classic, feel free to elevate your casserole with a dollop of sour cream, a sprinkle of chopped chives, or even some crispy fried onions for extra crunch. These add layers of texture and color that make your presentation pop and your palate sing.

Side Dishes

This casserole pairs beautifully with grilled or roasted meats like chicken, steak, or pork chops. Its hearty, creamy nature also balances perfectly with bright, fresh vegetable sides like steamed green beans, roasted Brussels sprouts, or a crisp garden salad.

Creative Ways to Present

Want to bring some fun flair to your Loaded Mashed Potato Casserole Recipe? Try serving it in individual ramekins for personal portions or turn it into a layered dip by adding a few layers of sour cream and bacon on top. You can even customize toppings like diced jalapeños or a drizzle of ranch dressing for a creative twist.

Make Ahead and Storage

Storing Leftovers

Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. Cover tightly with foil or plastic wrap to keep moisture in and avoid drying out.

Freezing

This dish freezes well, so you can prepare it in advance. Cool completely, then wrap the casserole dish tightly in foil or transfer portions to freezer-safe containers. Freeze for up to 2 months, making it ideal for meal prep or holiday planning.

Reheating

Reheat leftovers in the oven at 350°F for about 15-20 minutes until warmed through and bubbly again. You can also microwave single servings, but baking helps retain the casserole’s creamy texture and keeps the cheese nicely melted on top.

FAQs

Can I use instant mashed potatoes for this casserole?

Yes! Instant mashed potatoes can work well if you want to save time. Just ensure they are well-seasoned and creamy before mixing with the other ingredients for the best flavor and texture.

Is this casserole gluten-free?

Absolutely. This Loaded Mashed Potato Casserole Recipe uses naturally gluten-free ingredients, but always double-check packaged products like shredded cheese and bacon to confirm they haven’t added any gluten-containing additives.

Can I add other toppings or mix-ins?

Definitely! Feel free to get creative by adding sautéed mushrooms, caramelized onions, or diced bell peppers. You could also sprinkle in some ranch seasoning or garlic powder for an extra flavor boost.

How can I make this dish dairy-free?

Swap out the sour cream, butter, milk, and cheese with dairy-free alternatives like coconut cream or plant-based cheese. The texture and flavor will be slightly different, but it’s a great way to accommodate dietary restrictions.

What can I use instead of bacon?

If you prefer a vegetarian option, try crispy roasted chickpeas or smoky tempeh bits. These provide a satisfying crunch and a hint of smoky flavor without the meat.
