Kitchen Equipment

  • 9×13-inch baking dish
  • Large mixing bowl
  • Medium saucepan
  • Large skillet
  • Whisk
  • Measuring cups and spoons

Instructions

Step 1: Prepare the Potatoes

Thaw the frozen hash browns completely.

Pat them dry with paper towels to remove excess moisture. This helps prevent a watery casserole.

In a large bowl, combine:

  • Hash browns
  • Sour cream
  • Melted butter
  • Shredded cheddar cheese

Mix gently until evenly coated.

Step 2: Make the French Onion Sauce

Melt the butter in a skillet over medium heat.

Add the diced onion and cook for about 5–7 minutes until soft and lightly golden.

Stir in the garlic and cook for 30 seconds.

Sprinkle in the flour and cook for 1 minute while stirring.

Slowly whisk in the halal chicken broth and milk until smooth.

Season with:

  • Salt
  • Black pepper
  • Paprika
  • Dry mustard

Cook for 3–5 minutes until the sauce thickens.

Pour the hot sauce over the potato mixture and stir until everything is evenly coated.

Step 3: Bake

Preheat the oven to 350°F (175°C).

Transfer the mixture to a greased 9×13-inch baking dish.

Spread evenly.

Bake for 45–50 minutes until hot and bubbling.

Step 4: Prepare the Crispy Onions

While the casserole bakes, heat vegetable oil to 350°F (175°C).

Fry the sliced onions in small batches for 2–4 minutes until golden and crisp.

Transfer to paper towels and sprinkle lightly with salt.

If using store-bought crispy onions, skip this step.

Step 5: Finish the Casserole

Remove the casserole from the oven.

Sprinkle the crispy fried onions evenly over the top.

Return to the oven for 5–8 minutes until the topping is lightly toasted.

Serve warm.

Expert Tips

  • Always thaw and drain the potatoes before mixing.
  • Freshly grated cheddar melts better than pre-shredded cheese.
  • Don’t overcook the onions; they should be golden, not dark brown.
  • Let the casserole rest for 10 minutes before serving.
  • Homemade crispy onions provide the best flavor, but store-bought ones are a great time-saving option.

Common Mistakes to Avoid

  • Using frozen hash browns without thawing.
  • Skipping the draining step.
  • Overcooking the sauce until it becomes too thick.
  • Burning the onion topping.
  • Overbaking the casserole, which can dry it out.

Recipe Variations
