Ingredients You’ll Need

• 500 g (1 lb 2 oz) frozen shredded hash browns — thawed: Using frozen hash browns is a convenient shortcut, but ensure they are fully thawed and squeezed dry to prevent a soggy casserole. We recommend shredding your own potatoes for the best texture, but store-bought works in a pinch.
• 250 g (9 oz) sharp cheddar cheese, grated — plus extra for topping: Sharp cheddar provides a robust, tangy flavor that stands up to the other ingredients. Grating it yourself ensures a smoother melt and better flavor distribution. Don’t skimp on the extra for topping – it creates a beautiful golden crust!
• 150 g (5 oz) mozzarella cheese, shredded — for melt: Mozzarella adds a lovely stretch and creaminess to the casserole. It complements the cheddar beautifully and creates that irresistible cheesy pull.
• 200 g (7 oz) cooked chicken breast, diced — halal‑certified: Adding chicken transforms this casserole into a complete meal. Using pre-cooked chicken saves time, but rotisserie chicken works wonderfully too. Ensure it’s diced into small, even pieces for even distribution.
• 240 ml (1 cup) heavy cream: Heavy cream provides richness and a luxurious texture. It helps bind the ingredients together and creates a creamy sauce.
• 240 ml (1 cup) sour cream: Sour cream adds a delightful tanginess that balances the richness of the heavy cream and cheese. Full-fat sour cream is recommended for the best flavor and texture.
• 100 g (3½ oz) unsalted butter, melted — use halal butter: Melted butter coats the hash browns, preventing them from sticking together and adding a subtle richness. Using unsalted butter allows you to control the overall saltiness of the dish.
• 2 large eggs, lightly beaten: Eggs act as a binder, helping to hold the casserole together. Beating them lightly ensures they are evenly distributed.
• 1 medium onion, finely chopped: Onion adds a savory depth of flavor. Finely chopping it ensures it cooks evenly and blends seamlessly into the casserole.
• 2 cloves garlic, minced: Garlic provides a pungent aroma and flavor that complements the onion and other ingredients.
• 1 tsp (5 g) smoked paprika — for depth: Smoked paprika adds a smoky, slightly sweet flavor that elevates the casserole. It’s a key ingredient in Grandma’s secret blend!
• ½ tsp (2½ g) black pepper: Freshly ground black pepper adds a subtle spice and enhances the other flavors.
• ½ tsp (2½ g) salt: Salt balances the flavors and brings out the best in all the ingredients.
• 2 tbsp (30 ml) olive oil — for sauté: Olive oil is used for sautéing the onion and garlic, adding a healthy fat and subtle flavor.
• 2 tbsp (30 ml) fresh chives, thinly sliced — garnish: Fresh chives add a pop of color and a mild oniony flavor. They’re a beautiful garnish that brightens up the dish.
• 1 tsp (5 ml) hot sauce (optional) — subtle kick: A dash of hot sauce adds a subtle kick that complements the richness of the casserole. Use your favorite variety!

Let’s Build Grandma’s Hash Brown Casserole: Step-by-Step Instructions

1. Preheat & Prep: Begin by preheating your oven to 190°C (375°F). This ensures even cooking. Generously grease a 23 x 33 cm (9 x 13 in) baking dish with melted butter. Don’t skimp on the butter – it prevents sticking and adds flavor!
2. Sauté the Aromatics: Heat olive oil in a large skillet over medium heat. Add the finely chopped onion and minced garlic. Sauté for 3-4 minutes, stirring frequently, until they become fragrant and translucent. This step builds the flavor base of the casserole.
3. Cook the Chicken: Add the diced cooked chicken breast to the skillet with the onions and garlic. Sprinkle with smoked paprika, salt, and pepper. Cook for 5 minutes, stirring occasionally, until the chicken is lightly browned. This adds protein and a smoky depth to the casserole. Remove from heat and allow to cool slightly before combining with the other ingredients.
4. Combine the Base: In a large mixing bowl, combine the thawed hash browns, melted butter, heavy cream, sour cream, and lightly beaten eggs. Ensure the hash browns are thoroughly thawed to prevent a watery casserole.
5. Mix in the Goodness: Gently fold in the sautéed chicken mixture, grated cheddar cheese, shredded mozzarella cheese, and half of the sliced chives into the hash brown base. Mix until everything is evenly coated. Be careful not to overmix, as this can make the casserole dense.
6. Transfer & Top: Pour the mixture into the prepared baking dish and spread it evenly with a spatula. Sprinkle the remaining cheddar cheese in an even layer over the top. This creates a beautiful golden-brown crust.
7. Bake to Perfection: Bake uncovered for 45 minutes, or until the casserole is bubbling and the cheese is melted and golden brown. For an extra crispy top, switch the oven to broil and broil for an additional 2-3 minutes, watching closely to prevent burning.
8. Rest & Serve: Remove the casserole from the oven and let it rest for 10 minutes before serving. This allows the layers to set, making it easier to slice and serve.

The Secret to a Creamy Casserole: Dairy Balance

The perfect balance of heavy cream and sour cream is crucial for achieving the signature creamy texture of this casserole. Heavy cream provides richness, while sour cream adds a delightful tang that cuts through the richness and prevents the casserole from being overly heavy. Using both creates a harmonious flavor profile that’s incredibly satisfying.

Choosing the Right Cheese for Maximum Melt

We use a combination of sharp cheddar and mozzarella for a reason. Sharp cheddar delivers that classic, comforting flavor, while mozzarella is the champion of melt. It stretches beautifully and creates those irresistible cheesy pulls. Don’t substitute the mozzarella with another cheese if you want that perfect texture!

Why Thawing the Hash Browns Matters

Thawing the frozen shredded hash browns is a non-negotiable step. If you add them frozen, they’ll release excess water during baking, resulting in a soggy casserole. Properly thawed hash browns ensure a fluffy, cohesive texture that holds its shape beautifully.
