This one-dish wonder transforms the beloved loaded baked potato into a hearty family casserole that's ready in just over an hour. Tender cubed potatoes layer with shredded chicken, creamy sour cream mixture, sharp cheddar cheese, crispy bacon bits, and fresh green onions. The result delivers all those classic loaded potato flavors in a convenient format that feeds eight people without multiple pans or complicated timing.
My weeknight dinner struggles ended when I developed this recipe after countless burned bacon and cold potato disasters. This casserole cuts traditional loaded potato prep time from ninety minutes down to just twenty minutes of active work while delivering superior results.
Premium Ingredient Guide
- Large Russet Potatoes: fluffy interior absorbs flavors beautifully while holding shape when cubed properly
- Rotisserie Chicken: saves time while adding seasoned flavor, hand-shredded creates better texture than machine-chopped
- Full-Fat Sour Cream: creates creamiest base texture, never substitute light versions that curdle and lack richness
- Sharp White Cheddar: melts smoothly while providing bold flavor, freshly shredded blocks work better than pre-shredded
- Fresh Green Onions: use both white and green parts for layered onion complexity, choose firm stalks with bright tops
- Real Bacon Bits: authentic pieces beat artificial versions, thick-cut bacon crumbled yourself provides optimal flavor
- Whole Milk: adds necessary moisture without thinning creamy texture, lower-fat versions create dense results
Pre-baking potatoes the day before makes this recipe foolproof. Cooled potatoes cube easily without falling apart while preventing burns from hot potato handling during assembly.
Complete Assembly Process
- Oven and Dish Preparation
- Preheat oven to three hundred fifty degrees Fahrenheit and generously grease nine-by-thirteen inch baking dish with butter or cooking spray to prevent sticking during baking process.
- Potato Preparation Technique
- Peel completely cooled baked potatoes and cube into uniform one-inch pieces. Consistent sizing ensures even cooking throughout while maintaining proper texture in finished casserole.
- Foundation Layer Creation
- Arrange half the cubed potatoes evenly across bottom of prepared baking dish. This solid foundation supports all subsequent layers while ensuring balanced distribution throughout.
- Protein Layer Addition
- Distribute one cup shredded rotisserie chicken evenly over potato foundation. Hand-shredding creates better texture than purchasing pre-shredded varieties that can be stringy.
- Creamy Mixture Development
- Combine full-fat sour cream with whole milk in mixing bowl, whisking until completely smooth. This mixture binds all ingredients while creating luxurious creamy texture throughout casserole.
- First Sauce Application
- Pour half the sour cream mixture over chicken and potatoes, using spoon to spread evenly when necessary. Complete coverage ensures every bite contains creamy richness.
- Initial Topping Distribution
- Add half the shredded cheddar cheese, half the chopped green onions, and half the bacon bits over creamy layer. Reserve remaining toppings for final layer presentation.
- Layer Repetition Process
- Repeat entire layering sequence using remaining potatoes, chicken, sour cream mixture, and finish with remaining cheese, green onions, and bacon bits on top.
- Covered Baking Stage
- Cover tightly with aluminum foil and bake for thirty-five to forty minutes until cheese melts completely and edges bubble actively around dish perimeter.
- Golden Finishing Touch
- Remove foil and continue baking five to ten additional minutes until top develops beautiful golden color. Allow resting for five minutes before serving for proper setting.

My biggest learning curve involved rushing the resting period because everyone wanted to dig in immediately. Those five minutes make the difference between messy scoops and beautiful, cohesive portions that showcase all the layers.
Creative Serving Ideas
Present generous scoops alongside simple green salads or steamed broccoli for balanced meals. Crusty bread works wonderfully for soaking up creamy sauce remnants. This casserole also travels well for potluck gatherings where comfort food is always appreciated.
Delicious Recipe Variations
Transform basic recipe by adding diced jalapeños for spicy heat or substituting pepper jack cheese for more complex flavors. Turkey works excellently replacing chicken while vegetarian versions can use seasoned black beans or mushrooms for protein alternatives.
Storage and Reheating
Store leftover portions covered in refrigerator for up to four days maximum. Reheat individual servings in microwave or larger portions in oven at three hundred degrees until heated through completely. Texture remains excellent when properly stored and reheated.

This loaded baked potato chicken casserole represents comfort food perfection in convenient format. The dish proves that beloved restaurant flavors can be recreated at home using simple layering techniques and quality ingredients. Every forkful delivers that perfect combination of creamy, cheesy, smoky, and satisfying elements that make ordinary weeknight dinners feel like special occasions.
