📝 INGREDIENTS
For the Casserole
· 1 (30 oz) bag frozen shredded hash browns, thawed (or use refrigerated)
· 3 cups cooked shredded chicken (rotisserie chicken works perfectly)
· 1 medium yellow onion, finely diced
· 2 cups shredded cheddar cheese, divided (sharp is best)
· 1 cup shredded Monterey Jack or Colby Jack cheese
· 1 (10.5 oz) can cream of chicken soup (or cream of mushroom/celery)
· 1 (8 oz) container sour cream (full-fat for best flavor)
· ½ cup (1 stick / 113g) unsalted butter, melted
· 1 cup whole milk or half-and-half
· 1 tsp garlic powder
· 1 tsp onion powder
· ½ tsp paprika
· Salt and black pepper to taste
For the Topping
· 1 ½ cups cornflakes or crushed Ritz crackers (about 1 sleeve)
· 2 tbsp butter, melted
· ¼ cup grated Parmesan cheese (optional)
· 2 tbsp fresh chives or parsley, chopped (for garnish)
👩🍳 INSTRUCTIONS
Step 1: Prep & Preheat
- Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
- If using frozen hash browns, spread them out on a tray to thaw for 30 minutes, or squeeze excess moisture from them in a clean kitchen towel.
Step 2: Mix the Filling
- In a very large mixing bowl, combine the thawed hash browns, shredded chicken, diced onion, 1 ½ cups of the cheddar cheese, and all of the Monterey Jack cheese.
- In a separate bowl, whisk together the cream of chicken soup, sour cream, melted butter, milk, garlic powder, onion powder, paprika, salt, and pepper until smooth.
- Pour the soup mixture over the hash brown mixture. Stir gently until everything is evenly coated.
Step 3: Assemble & Top
- Pour the mixture into the prepared baking dish and spread it into an even layer.
- Sprinkle the remaining ½ cup cheddar cheese over the top.
- In a small bowl, toss the cornflakes (or crushed crackers) with the 2 tbsp melted butter. Sprinkle evenly over the cheese layer. Add optional Parmesan on top.
Step 4: Bake
- Bake, uncovered, for 45-55 minutes, until the casserole is bubbly around the edges and the topping is deep golden brown.
- Let it rest for 10-15 minutes before serving (this allows it to set for cleaner slices). Garnish with fresh chives or parsley.

💡 PRO TIPS & VARIATIONS
· Thaw Hash Browns: This is crucial! Frozen potatoes will make the bake watery and extend cooking time.
· Shred Your Own Cheese: Pre-shredded cheese contains anti-caking agents that can make sauces grainy. Freshly shredded melts smoother.
· Add Veggies: Stir in 1-2 cups of thawed, drained frozen broccoli florets, peas, or diced bell peppers with the hash browns.
· Make it Spicy: Add a 4 oz can of diced green chiles, or mix ½ tsp cayenne pepper into the sauce.
· Breakfast Version: Substitute the chicken with 1 lb cooked, crumbled breakfast sausage or bacon. Perfect for brunch!
· Lighter Option: Use low-fat soup, Greek yogurt instead of sour cream, and reduced-fat cheese.
Cooking Methods:
· Slow Cooker: Mix everything (except topping) and pour into a greased slow cooker. Cook on LOW for 4-5 hours. Add topping in the last 30 minutes, with the lid vented.
· Make Ahead: Assemble completely (without topping), cover, and refrigerate for up to 24 hours. Add topping and bake as directed, adding 10-15 extra minutes.
