Ingredients

• 32 oz Frozen shredded hash browns
• 1 large Yellow onion
• 4 tbsp Unsalted butter
• 2 cups Shredded sharp cheddar cheese
• 1.5 cups Sour cream
• 10.5 oz Cream of chicken soup
• 1 tsp Garlic powder
• 1 tsp Onion powder
• 1 tsp Salt
• 0.5 tsp Black pepper
• 1.5 cups Crushed potato chips or panko breadcrumbs (for topping)
• 0 Nonstick cooking spray

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with nonstick cooking spray and set aside.

Step 2

In a medium skillet, melt 2 tablespoons of butter over medium heat. Add the chopped onion and sauté until softened and fragrant, about 5 minutes. Remove from heat and set aside.

Step 3

In a large mixing bowl, combine the thawed hash browns, sour cream, cream of chicken soup, sautéed onions, shredded cheddar cheese, garlic powder, onion powder, salt, and black pepper. Mix until evenly blended.

Step 4

Transfer the mixture into the prepared casserole dish and spread it out evenly.

Step 5

In a small microwave-safe bowl, melt the remaining 2 tablespoons of butter. Toss the melted butter with the crushed potato chips or panko breadcrumbs to create the topping.

Step 6

Sprinkle the buttery topping evenly over the casserole.

Step 7

Bake in the preheated oven for 40-45 minutes, or until the casserole is bubbly around the edges and the topping is golden brown.

Step 8

Remove from the oven and let it rest for 5 minutes before serving. Enjoy warm!
