Instructions
Make the Casserole
Preheat the oven to 350°F. Lightly grease a 9x13-inch baking dish with butter or cooking spray.
In a large bowl, combine the sour cream, cream of chicken soup, ¼ cup melted butter, diced onion (or onion powder), salt, and pepper. Stir until smooth.
Fold in 1.5 cups of the shredded cheddar cheese until evenly distributed.
Add the thawed, well-drained hash browns to the bowl and fold everything together until the hash browns are evenly coated in the creamy cheese mixture.
Assemble and Top
Spread the hash brown mixture evenly into the prepared baking dish and press down gently with a spatula.
Sprinkle the reserved ½ cup of cheddar cheese evenly over the top.
In a small bowl, toss the crushed crackers with 3 tablespoons melted butter until every crumb is coated. Scatter the cracker mixture over the cheese in an even layer.
Bake
Bake uncovered for 45-55 minutes, until the casserole is bubbling around the edges and the cracker topping is golden and crisp.
If the topping starts browning too quickly, tent loosely with foil for the last 10-15 minutes.
Remove from the oven and let rest for 10 minutes before serving. This allows the casserole to set up for clean, scoopable servings.
Notes
Thaw and drain the hash browns: This is the most important step. Squeeze thawed hash browns in a clean towel to remove excess moisture, or the casserole will turn out watery.
Shred your own cheese: Block cheese melts smoother than pre-shredded, which contains anti-caking starch.
Make ahead: Assemble without the cracker topping, cover, and refrigerate up to 24 hours. Add topping just before baking, and add 10-15 minutes to bake time.
Freezing: Freeze the assembled, unbaked casserole (without topping) tightly wrapped for up to 3 months. Thaw overnight in the fridge before baking.
No-soup version: Replace the canned soup with ¾ cup heavy cream whisked with 1 teaspoon chicken bouillon, thickened with a butter-flour roux.
