Loaded Baked Potato & Chicken Casserole
There’s a special kind of joy baked into casseroles. Maybe it’s the creamy richness, or the way each bite seems to hug you from the inside out. I first served this dish one frosty Halloween—costumes, candlelight, and horror movie banter made the perfect backdrop. It disappeared in minutes. This casserole doesn’t just fill plates—it brings people together.

Key Ingredients and Flavor Harmony
This dish is built on the savory foundation of tender shredded chicken, starchy baked russet potatoes, smoky bacon, and an irresistible blend of cheeses. Sharp cheddar delivers boldness, sour cream adds tang, and green onions brighten every forkful. Garlic punctuates the mix with a warm bite, while the optional veggies sneak in extra heartiness.
Ingredient Selection Tips
Chicken: Always go for organic or free-range when possible. Breasts should appear plump and moist, never pale or overly wet.
Potatoes: Russets reign supreme. Choose firm, weighty ones without blemishes or softness.
Bacon: Thick-cut bacon adds crunch and depth. Look for a solid meat-to-fat ratio, without excess moisture.
Cheese: Freshly shredded is key. Sharp cheddar is a must, and pepper jack adds a spicy twist.
Green Onions: Select vibrant green stalks. Avoid limp or yellowing ones.
Sour Cream: Full-fat delivers richness. Always check the date for freshness.

Ingredients
- 4 large russet potatoes, thoroughly scrubbed
- 2 cups shredded cooked chicken (about 2 large breasts)
- 6 slices thick-cut bacon, cooked and crumbled
- 2 cups sharp cheddar cheese, shredded
- 1 cup sour cream
- 1/2 cup milk
- 1/4 cup finely chopped green onions (plus more for garnish)
- 2 garlic cloves, minced
- Salt and pepper to taste
- 1 tsp paprika (optional)
- 1/2 cup cooked broccoli or spinach (optional add-in)
Instructions
Bake the Potatoes
Preheat oven to 425°F (220°C). Prick potatoes with a fork and bake directly on the rack for 45–60 minutes, until fork-tender.
Cook the Chicken
Season chicken with salt, pepper, and paprika. Bake at 375°F or grill over medium heat until fully cooked (20–25 minutes). Let rest for 5 minutes before shredding.
Prepare the Filling
Let baked potatoes cool slightly. Halve them, scoop out the insides, and mash in a large bowl. Mix in sour cream, milk, minced garlic, half the cheddar, chopped green onions, and half the bacon. Add salt and pepper to taste. Blend until creamy.
Assemble the Casserole
Fill each potato skin generously with the mashed mixture. Top with shredded chicken, then sprinkle with the remaining cheese and bacon.
Bake to Perfection
Place loaded potato skins in a baking dish. Bake at 425°F for 15–20 minutes, or until cheese is bubbling. Broil for 1–2 minutes at the end for a golden finish—watch closely!
