The Best Hash Potato Casserole Recipe Tutorial

Ingredients You’ll Need

Shredded Hash Brown Potatoes – The base of the casserole, these give the dish its hearty comfort. I often shred my own potatoes, but frozen hash browns work perfectly.
Cheddar Cheese – Sharp cheddar melts into the potatoes, giving that creamy, cheesy bite everyone craves.
Cream of Chicken Soup – Adds a savory richness that binds everything together. You can swap it for cream of mushroom or even homemade soup base if you prefer.
Sour Cream – This adds tang and creaminess, balancing the richness of the cheese and butter.
Butter – Melted butter brings depth and helps create that golden topping.
Onion – A little onion gives the casserole flavor and warmth without overpowering it.
Cornflakes (or Crushed Crackers) – The crunchy topping that makes this casserole stand out. That buttery crunch is what makes every bite special.
Salt and Pepper – Just enough seasoning to bring everything together.

I added some garden-fresh tomatoes and cilantro to my dish on the day of creating this post. Though you can use any toppings you desire to make it delicious and special.

Step-by-Step Instructions

Step 1: Mix the Base

In a large bowl, combine the shredded hash browns, cheddar cheese, cream of chicken soup, sour cream, onion, and seasonings. Stir until everything is well mixed and creamy.

Step 2: Transfer to Baking Dish

Spread the mixture evenly into a greased 9×13 casserole dish. This ensures even baking and keeps the edges golden brown.

Step 3: Add the Crunchy Topping

In a small bowl, mix crushed cornflakes (or crackers) with melted butter. Sprinkle evenly over the top of the casserole. This layer will bake up golden and crunchy.

Step 4: Bake Until Golden

Bake uncovered at 350°F for about 45 minutes, until the topping is golden brown and the casserole is bubbling at the edges.

Crushed Ritz crackers, bread crumbs, or even crushed potato chips make a great substitute if you don’t have cornflakes on hand.
