Step 1

Place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain bacon slices on paper towels and break into small pieces.

Step 2

Preheat the oven to 400 degrees F (200 degrees C). Spray a 9x4-inch loaf pan with cooking spray.

Step 3

Mix sour cream, butter, and seasoning blend together in a bowl. Layer 2 1/2 hash browns in the prepared dish. Spread 1/3 of the sour cream mixture over hash browns. Sprinkle 1/4 cup Cheddar cheese and 1/3 of the bacon on top. Repeat layers twice more. Sprinkle chives and pepper over casserole. Cover with aluminum foil.

Step 4

Bake in the preheated oven until cheese is golden brown and casserole is heated through, about 1 hour.
