Ingredients You’ll Need

The magic of this casserole comes from combining familiar, hearty ingredients that bring out the best in each other. Choosing quality potatoes and sharp cheddar cheese really makes a difference, and don’t skip the crispy bacon—it adds that crave-worthy crunch and smoky flavor.

• Idaho potatoes: These starchy potatoes are perfect for mashing, giving you a fluffy, creamy texture.
• Milk: It helps loosen the mash just enough without making it runny; whole milk works best for creaminess.
• Cream cheese: Adds an indulgent richness and keeps the casserole silky smooth.
• Butter: Use room temperature butter for easy mixing and that wonderful buttery flavor.
• Sour cream: Provides tang and lifts the flavors, balancing the richness.
• Kosher salt: Essential for seasoning, bringing out every taste.
• Pepper: A touch of black pepper for warmth and subtle heat.
• Garlic powder: Adds a mild savory note without overpowering the potatoes.
• Chives: Freshly chopped, they add color and a mild oniony brightness.
• Cheddar cheese: Go for sharp cheddar for bold flavor that melts beautifully.
• Bacon strips: Crisped and chopped for that smoky, crunchy texture that balances softness.

Variations

I love tweaking this Cheddar Bacon Mashed Potato Casserole Recipe depending on the occasion or what I have on hand. Feel free to make it your own by swapping ingredients or adding little extras to suit your family’s tastes.

• Veggie boost: I sometimes mix in sautéed mushrooms or roasted garlic for extra depth and earthiness.
• Cheese swap: Once, I used smoked gouda instead of cheddar, and it added a lovely smoky creaminess that paired wonderfully with the bacon.
• Diet-friendly: For a lighter version, use Greek yogurt instead of sour cream and reduce butter—still gets you that creamy texture without the full fat.
• Spicy twist: Add a pinch of cayenne or chopped jalapeños inside if you like a little heat.

How to Make Cheddar Bacon Mashed Potato Casserole Recipe

Step 1: Prep and Boil the Potatoes Until Tender

Start by peeling and cubing your Idaho potatoes into evenly sized pieces—this helps them cook at the same rate. Pop them into a large pot of salted water and bring to a boil. You’ll want to cook them until they’re fork-tender, which usually takes about 15–20 minutes. Don’t overcook or they’ll soak up too much water, making your mash watery.

Step 2: Mash with Cream Cheese, Butter, and Sour Cream

Once drained, put the potatoes back in the pot or a big bowl and get ready to mash. Add softened cream cheese, butter, sour cream, and milk little by little. I like to use a handheld masher for a sturdy texture, but if you want ultra-smooth potatoes, a hand mixer works too. Season with kosher salt, pepper, and garlic powder while mixing it all together. Taste as you go to get that perfect balance.

Step 3: Stir in Chives, Bacon, and Sharp Cheddar

Fold in the chopped chives and crispy bacon pieces—this adds freshness and crunch that keeps every bite interesting. Then sprinkle in most of the shredded cheddar, reserving a handful to top the casserole before baking. Mixing these in while the potatoes are still warm helps the cheese melt beautifully.

Step 4: Bake Until Golden and Bubbling

Transfer your cheesy, bacon-studded mashed potatoes into a buttered casserole dish, then top evenly with the remaining cheddar. Pop it in a preheated oven at 350°F (175°C) for about 25-30 minutes. You’ll know it’s ready when the cheese on top is melted, bubbling, and just starting to turn golden. This is when that irresistible aroma really fills the kitchen.

How to Serve Cheddar Bacon Mashed Potato Casserole Recipe

Garnishes

I usually finish mine with a sprinkle of extra fresh chives or green onions for color and a bit of bite. Sometimes I toss on a small dollop of sour cream on each serving for extra creaminess. It makes the casserole look so inviting and adds that little touch that makes everyone smile.

Side Dishes

This casserole pairs wonderfully with roasted vegetables, green beans almondine, or a simple crisp salad. I also love serving it alongside a juicy roasted chicken or grilled steak for a fully comforting, crowd-pleasing dinner.

Creative Ways to Present

For special occasions, I’ve baked individual portions in ramekins topped with a sprinkle of extra bacon and a chive sprig. It makes it feel fancy and perfect for holiday dinners or potlucks. You can also layer the casserole in a clear baking dish so guests can peek at those tempting layers of cheddar and bacon.

Make Ahead and Storage

Storing Leftovers

I keep leftovers covered in an airtight container in the fridge for up to 3 days. The casserole keeps its flavor really well, just a bit denser when chilled. If you want to freshen it up, add a spoonful of milk or sour cream before reheating.

Freezing

Freezing works well if you prepare extra. I portion it out into freezer-safe containers, and it can stay frozen for up to 2 months. Just thaw it overnight in the fridge before reheating for best results. The texture might be slightly different but still delicious.

Reheating

I reheat leftovers in the oven at 350°F, covered loosely with foil to keep moisture in, for about 20-25 minutes. Stir halfway through if possible. If you’re in a hurry, the microwave works too, but add a splash of milk to keep the potatoes creamy as they heat.
