Tip for mashed potatoes
Use smooth, well-seasoned mashed potatoes. Chunky potatoes won’t spread evenly and can dry out.
🔥 Step-by-Step: How to Build the Perfect Layers
1. Preheat & Prepare
Preheat oven to 375°F (190°C) and grease a baking dish.
2. Make the Creamy Chicken Base
In a large bowl, mix together:
-
Sour cream
-
Cream cheese
-
Ranch seasoning
Stir until smooth, then fold in the shredded chicken until evenly coated.
This layer stays incredibly juicy during baking.
3. Assemble the Casserole
Spread the creamy chicken mixture evenly into the prepared dish.
Gently spoon the mashed potatoes over the top and spread carefully to avoid mixing the layers.
4. Add the Cheese
Sprinkle shredded cheddar evenly over the mashed potatoes.
This creates a lightly crisp, golden finish.
5. Bake
Bake uncovered for 35–40 minutes, until:
-
Bubbling at the edges
-
Cheese lightly golden
-
Fully heated through
Let rest 5–10 minutes before serving.
🧠 Why Mashed Potatoes Work So Well Here
Mashed potatoes act as both a texture layer and moisture seal. They trap steam, keeping the chicken layer creamy while gently crisping on top.
