Loaded Baked Potato Casserole

Let’s be honest—when was the last time someone complained about too much cheese, bacon, or potatoes in one dish? Never, that’s when. This loaded baked potato casserole takes everything you love about a perfect baked potato and transforms it into a crowd-pleasing, spoon-ready comfort food masterpiece that’ll have everyone scraping the dish clean.

The beauty of this casserole is how it combines creamy, fluffy potato insides with the satisfying crunch of bacon and the sharp tang of cheddar. Each bite delivers that perfect balance of textures—velvety potatoes enriched with cream cheese and sour cream, punctuated by smoky bacon bits and the fresh pop of chives. It’s essentially a loaded baked potato that’s been deconstructed and rebuilt into its most delicious possible form.

Ingredients

• 4 large russet potatoes (3½ to 4 pounds total)
• Cooking spray
• 4 tablespoons unsalted butter
• 4 ounces cream cheese
• 1 pound sliced bacon
• 2/3 cup sour cream
• 1/2 cup whole milk, plus more as needed
• 1 large bunch fresh chives
• 8 ounces sharp cheddar cheese, shredded (about 2 cups)
• 1 teaspoon seasoned salt

Steps

1. Arrange a rack in the middle of the oven and heat to 400°F (205°C). This higher temperature helps create that perfect crispy potato skin that adds texture to the casserole.
2. Place 4 large russet potatoes directly on the oven rack (no foil wrapping). Bake until completely cooked through and easily pierced to the center with a knife, 1 hour to 1 hour 15 minutes. The potatoes should yield easily to the knife with no resistance—if there’s any firmness, they need more time. Meanwhile, coat an 8×8-inch square or other 2-quart baking dish with cooking spray, ensuring all corners are covered to prevent sticking. Place 4 tablespoons unsalted butter and 4 ounces cream cheese in a large bowl and let sit at room temperature until softened—this prevents lumps in your final mixture.
3. Working in batches if needed, cook 1 pound bacon in a large skillet over medium heat until crispy, about 8 minutes. For even cooking, don’t overcrowd the pan, which can cause the bacon to steam rather than crisp. Alternatively, cook the bacon on a large rimmed baking sheet in the oven while the potatoes bake. It will take 12 to 14 minutes at 400°F (205°C), depending on the thickness of the bacon. Let drain on a paper towel-lined plate, then crumble into small pieces once cool enough to handle.
4. Remove the baked potatoes from the oven. When cool enough to handle but still warm (about 5-10 minutes), cut in half lengthwise. Carefully scoop the flesh out with a spoon into the bowl with butter and cream cheese, leaving a thin layer attached to the skin to help maintain their structure. Add 2/3 cup sour cream and 1/2 cup whole milk and mash with a potato masher until the butter and cream cheese are fully melted and everything is combined. For the creamiest texture, don’t overmix—stop once ingredients are just incorporated. If the mixture is very thick, mix in more milk 1 tablespoon at a time until you reach a smooth, fluffy consistency.
5. Finely chop 1 large bunch fresh chives until you have 6 tablespoons. If needed, shred 8 ounces sharp cheddar cheese on the large holes of a box grater (about 2 cups). Pre-shredded cheese works too, but freshly grated melts more smoothly due to the absence of anti-caking agents.
6. Add 1/4 cup of the chives, 1 1/4 cups of the cheese, all but 1/2 cup of the bacon, and 1 teaspoon seasoned salt to the mashed potatoes and stir to combine. Taste and adjust seasonings if needed—the mixture should be well-seasoned as the additional toppings will be added later. Transfer to the baking dish and spread into an even layer, creating some texture on top with the back of a spoon for crispy edges. Sprinkle with the remaining 3/4 cup cheese, ensuring even coverage.
7. Bake until heated through and the cheese is melted and beginning to bubble and brown at the edges, 20 to 25 minutes. For a more golden top, switch to broil for the final 1-2 minutes, watching carefully to prevent burning. Remove from the oven and let stand for 5 minutes to set. Sprinkle with the remaining bacon and chives just before serving to maintain their texture and color.

Smart Swaps

• Greek yogurt instead of sour cream (1:1 ratio) – adds protein while maintaining creaminess
• Cauliflower can replace half the potatoes – reduce carbs while keeping the texture
• Turkey bacon instead of regular bacon – cuts fat by about 30% with minimal flavor loss
• Nutritional yeast (about 3 tablespoons) can replace some of the cheese for a dairy-sensitive option

Make It Diabetes-Friendly

• Use half cauliflower, half potato to reduce carbs by approximately 15g per serving
• Replace whole milk with unsweetened almond milk (reduces carbs by 6g per serving)
• Use half the bacon and focus on it as a garnish rather than mixed throughout
• Add 1/2 teaspoon xanthan gum to maintain creaminess with less fat
• Serve with a side of non-starchy vegetables to balance the meal’s glycemic impact

Pro Tips

• For ultra-fluffy potatoes, use a ricer instead of a masher
• Warm your milk before adding to prevent the potatoes from cooling too quickly
• For make-ahead convenience, assemble everything but don’t add the final cheese topping until ready to bake
• Let the casserole rest for 10 minutes before serving to help it set and make cleaner portions
