Chicken Little Casserole – Ingredients

• 6 cups mashed potatoes (homemade or store-bought)
• 4 cooked chicken breasts, shredded
• 1–2 cans (10.5 oz each) condensed cream of chicken soup
• 1/2 cup whole milk
• 1/2 cup sharp cheddar cheese, grated
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon dried rosemary
• 1/2 teaspoon dried thyme
• Kosher salt and freshly ground black pepper, to taste

 

Step-by-Step Directions:

Step 1: Prep the Oven and Pan: Preheat your oven to 350°F (175°C). Lightly grease the interior floor and sidewalls of a standard 9×13-inch baking dish with non-stick cooking spray to prevent the potato starches from sticking to the base.

 

Step 2: Emulsify the Herbal Gravy Matrix: In a medium mixing bowl, combine your 1 / to 2 / cans of condensed cream of chicken soup, 1/2 / cup of whole milk, 1/2 / teaspoon of garlic powder, 1/2 / teaspoon of onion powder, 1/2 / teaspoon of dried rosemary, and 1/2 / teaspoon of dried thyme. Whisk the elements together vigorously until smooth, then season generously with kosher salt and black pepper to taste.

 

 

Step 3: Build the Potato Foundation: Spread your 6 cups of mashed potatoes into an even, completely flat layer across the bottom floor of the greased baking dish, pressing them down slightly to form a solid structural base.

Step 4: Layer the Chicken and Canopy: Evenly scatter your 4 cooked, shredded chicken breasts directly over the top of the mashed potato layer. Slowly pour your seasoned cream gravy sauce uniformly across the poultry layer, ensuring every single shred of meat is well coated and submerged.

Step 5: Top with the Cheddar Crown: Sprinkle your 1/2 / cup of grated sharp cheddar cheese completely uniformly over the wet gravy canopy, creating a beautiful grid that will melt down to lock the elements in place.

Step 6: Bake to a Bubbling Finish: Slide the casserole dish onto the center rack of your preheated oven. Bake open and undisturbed for 25 / to 30 / minutes. Keep a highly vigilant eye on your structural indicators: the dish is perfectly ready the exact moment the perimeter borders are bubbling aggressively, the center is piping hot, and the cheddar crown is completely melted and golden.

Step 7: The Structural Rest and Service: Remove the sizzling dish from the oven and let it stand completely undisturbed on your counter for 5 / to 10 / minutes.

Tip: Do not skip this cooling window! Giving the casserole a brief rest allows the hot cream soup lipids and meat proteins to settle and thicken up perfectly, ensuring you can scoop clean, cohesive portions that hold their shape on the plate. Serve warm straight from the pan!
