Ingredients
For the Casserole:

1 medium yellow onion, finely diced
2 cups (8 oz) sharp cheddar cheese, shredded
1 cup (4 oz) Monterey Jack cheese, shredded
1 (10.5 oz) can cream of chicken soup (or cream of mushroom for vegetarian)
1 (8 oz) container sour cream (full-fat recommended)
1 cup whole milk or half-and-half
½ cup (1 stick) unsalted butter, melted
1 teaspoon garlic powder
1 teaspoon smoked paprika
½ teaspoon black pepper
1 teaspoon kosher salt (adjust to taste)
For the Topping:
2 cups cornflakes, lightly crushed (or 1 ½ cups panko breadcrumbs)
3 tablespoons unsalted butter, melted
2 tablespoons grated Parmesan cheese
1 tablespoon chopped fresh chives or parsley (optional, for garnish)
Equipment Needed
9×13 inch baking dish
Large mixing bowl
Skillet (for onion, if sautéing)
Measuring cups and spoons
Mixing spoons
Step-by-Step Instructions
Step 1: Prep and Preheat
Preheat your oven to 350°F (175°C). Grease the 9×13 inch baking dish with butter or non-stick spray. If you prefer a softer, non-crunchy onion, sauté the diced onion in a tablespoon of butter over medium heat until translucent, about 5 minutes. Let cool slightly. (For more texture, you can use it raw.)
Step 2: Mix the Creamy Base
In the large mixing bowl, combine the cream of chicken soup, sour cream, whole milk, and the ½ cup of melted butter. Whisk until smooth and well blended. Stir in the garlic powder, smoked paprika, black pepper, and salt.
Step 3: Combine Everything
Add the partially thawed hash browns, diced onion, sharp cheddar, and Monterey Jack cheeses to the creamy base. Use a large spoon or spatula to fold everything together until the potatoes are evenly coated. Be thorough but gentle.
Step 4: Assemble
Pour the potato mixture into the prepared baking dish. Spread it out into an even layer with the back of your spoon.
Step 5: Create the Crispy Topping
In a small bowl, mix the lightly crushed cornflakes with the 3 tablespoons of melted butter and the Parmesan cheese until the crumbs are evenly moistened. Sprinkle this mixture evenly over the entire surface of the casserole.
Step 6: Bake to Perfection
Place the dish on the center rack of the preheated oven. Bake, uncovered, for 55-65 minutes. The casserole is done when the edges are bubbling vigorously, the topping is deep golden brown, and the center is hot. A thermometer inserted into the center should read at least 160°F.
Step 7: Rest and Serve
Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This allows the sauce to thicken slightly, making it easier to slice and serve. Garnish with fresh chives or parsley if desired.
Make-Ahead and Storage Instructions
Make Ahead: Complete steps 1-4, cover the dish tightly with plastic wrap and then foil, and refrigerate for up to 24 hours. Store the topping mix separately in a bag. When ready to bake, sprinkle on the topping and add 10-15 minutes to the bake time.
Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.
Reheating: Reheat individual portions in the microwave. For larger portions, cover with foil and reheat in a 350°F oven until warmed through (20-30 minutes).
Freezing: Assemble and freeze before baking. Thaw overnight in the refrigerator and then bake as directed, adding extra time as needed. Freezing after baking can make the potatoes watery.
Recipe Variations & Tips
Vegetarian: Use cream of mushroom or celery soup.
Protein Add-In: Stir in 1-2 cups of diced cooked ham, crumbled cooked bacon, or browned breakfast sausage for a heartier main dish.
Lighter Version: Use low-fat soup, reduced-fat cheese, and Greek yogurt in place of sour cream. Note: texture and richness will change.
Cheese Swap: Try Gruyère, Colby Jack, or a Mexican blend for a different flavor profile.
Gluten-Free: Use a gluten-free cream soup and ensure your cornflakes or use gluten-free breadcrumbs.
Pro Tip: Do not fully thaw the hash browns—they should still be icy but breakable. This prevents the casserole from becoming gummy.
