How to Make Cheesy Potato Casserole

Step 1: Preheat your oven to 375°F. Heat a medium skillet over medium heat and melt 2 tablespoons of butter. Add the chopped onion and cook for 5 minutes until starting to soften. Then add the chopped garlic and cook for an additional 2 minutes. Remove from heat and let the mixture cool slightly.
Step 2: In a large mixing bowl, combine the sour cream, condensed cream of chicken soup, shredded cheddar cheese, thawed hash browns, and the cooked onion and garlic mixture. Stir well to evenly mix all ingredients.
Step 3: Grease a 3-quart casserole dish with butter. Transfer the mixture to the dish and cover with foil. Bake in the preheated oven for 45 minutes to allow the flavors to meld and potatoes to cook through.
Step 4: While the casserole bakes, melt the remaining 6 tablespoons of butter in a small bowl using the microwave for 45 to 60 seconds. Stir in the breadcrumbs and chopped parsley until well combined.
Step 5: Remove the casserole from the oven and carefully uncover it. Spread the breadcrumb mixture evenly over the top of the casserole. Return it to the oven uncovered and bake for an additional 25 to 30 minutes until the topping is golden brown and bubbly all over.
