Grandma’s Hash Brown Casserole Ingredients
For the Casserole
- Frozen Hash Browns – Provides the base of the casserole; use shredded or diced. No need to thaw completely; break up clumps before mixing.
- Cream of Chicken Soup – Adds creaminess. Can substitute with cream of mushroom or celery for a vegetarian version.
- Sour Cream – Adds tanginess and richness. Greek yogurt can be used for a lighter option with more protein.
- Butter – Essential for flavor and binding. Use salted for richness; unsalted for controlled seasoning.
- Cheddar Cheese – Provides classic taste; freshly shredded melts better. Can mix varieties like Colby Jack or Monterey Jack for different flavors.
- Onion – Finely chopped for sweetness and depth. Can sauté beforehand or add raw for a stronger bite.
- Salt & Pepper – Season to taste; adjust according to cheese and soup saltiness.
- Cornflakes/Breadcrumbs – Optional topping for added crunch. Combine with melted butter for best results.
Step‑by‑Step Instructions for Grandma’s Hash Brown Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take a 9×13-inch baking dish and liberally grease it with butter or cooking spray. This crucial step ensures that your delicious Grandma’s Hash Brown Casserole won’t stick and will come out easily, creating crisp edges that everyone loves.
Step 2: Combine the Base Ingredients
In a large mixing bowl, pour in a can of cream of chicken soup, followed by sour cream and melted butter. Using a spatula, stir the mixture vigorously until it becomes smooth and well-blended. This creamy base is pivotal for your casserole, adding rich flavor and texture that will surround the hash browns as they bake.
Step 3: Add Flavor Elements
Next, incorporate the chopped onion, freshly shredded cheddar cheese, and a pinch of salt and pepper into the creamy mixture. Stir until all the ingredients are nicely combined, infusing your Grandma’s Hash Brown Casserole with a delightful depth of flavor. The cheese should start to melt nicely into the mixture, and the onions will provide a subtle sweetness.
Step 4: Fold in the Hash Browns
Gently add the frozen hash browns to the mixture, folding them in carefully to avoid mashing. It’s important that the hash browns remain intact, as they create that signature texture in your casserole. Ensure each piece is coated in the creamy mixture for even distribution of flavor throughout, ready for the oven.
Step 5: Transfer to the Baking Dish
Pour the entire mixture into your pre-greased baking dish, spreading it evenly across the bottom. This will help the casserole bake uniformly. If you desire an extra layer of flavor, sprinkle crushed cornflakes on top, combined with a drizzle of melted butter for a crispy finish. This topping will turn beautifully golden as it bakes.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and let it bake uncovered for 45–55 minutes. Keep an eye on it as the time approaches; you’re looking for a golden, bubbly surface that indicates it’s ready to come out. The corners will be crisped up perfectly, and the center will be soft and inviting.
Step 7: Let it Rest Before Serving
Once baked to perfection, remove your Grandma’s Hash Brown Casserole from the oven and let it rest for about 10 minutes. This resting period allows the casserole to set just enough for easier slicing. If you like, garnish with fresh parsley or sliced green onions for an extra pop of color and flavor before serving.
