How to Make Hashbrown Casserole
Step 1: Preheat and Prepare
Preheat your oven to 375°F. Grease a 9×13-inch baking dish to prevent sticking.
Step 2: Mix the Ingredients
In a large bowl, combine the hashbrowns, shredded cheddar cheese, sour cream, cream of chicken soup, melted butter, chopped onion, garlic powder, salt, and pepper. Stir everything together until well combined.
Step 3: Transfer to Baking Dish
Spread the mixture evenly into the greased baking dish, smoothing out the top.
Step 4: Add the Crunchy Topping
In a small bowl, mix crushed cornflakes (or Ritz crackers) with melted butter. Sprinkle the mixture over the casserole for a crispy, golden topping.
Step 5: Bake to Perfection
Bake uncovered for 40-45 minutes, or until the casserole is golden brown and bubbling. Let it cool for a few minutes before serving.
Pro Tips for Making the Recipe
- Use Freshly Grated Cheese: Pre-shredded cheese contains anti-caking agents that can affect the creaminess.
- Let the Hashbrowns Thaw: This ensures even baking and prevents a watery casserole.
- Make it Meatier: Add cooked bacon, ham, or sausage for an extra protein boost.
- Switch Up the Topping: Try panko breadcrumbs or crushed potato chips for a fun twist.
How to Serve
- Classic Breakfast Side: Serve alongside eggs and bacon for a hearty breakfast.
- Brunch Favorite: Pair with fresh fruit and a side salad for a balanced meal.
- Dinner Companion: Serve as a side with roasted chicken, grilled steak, or BBQ ribs.
- Taco Night Twist: Top with salsa and jalapeños for a Tex-Mex variation.
