Cheesy potatoes always mean comfort around my table This creamy cheesy hash brown casserole topped with buttery crisp cornflakes checks every box for a hearty side dish that steals the spotlight at potlucks family dinners or holiday spreads I am always amazed how quickly it disappears no matter the crowd
I first made this dish for a friend’s family gathering and now it is always requested for every major holiday at my house My kids call dibs on leftovers before they even hit the fridge
Ingredients
- Diced or shredded hash brown potatoes: Frozen potatoes make this recipe so quick but I always look for hash browns with no additives or weird coloring
- Unsalted butter: It adds a rich flavor throughout and makes the topping irresistible Always choose high quality butter for best results
- Salt and freshly ground black pepper: Essential seasoning for pulling everything together Use fresh pepper for more punch
- Sour cream: Creaminess and tang that balances the cheese I use full fat for best texture
- Sharp cheddar cheese: The big cheesy flavor comes from sharp cheddar Always grate your own if you can for smoother melting
- Monterey Jack cheese: Mildly creamy and helps the casserole stay extra gooey Freshly grated works best
- Onion and garlic: The real flavor makers Dice onion fine so it melts into the sauce and mince garlic for best results
- All purpose flour: Needed to thicken the homemade creamy chicken sauce Unbleached flour keeps flavors pure
- Low sodium chicken broth or stock: Adds savory richness without too much salt Use good quality or homemade stock if possible
- Milk: Whole milk gives the creamiest base but two percent works in a pinch
- Crushed cornflakes: The classic crunchy topping adds contrast to all the softness
- Creamy Chicken Sauce: Homemade sauce is so much tastier than canned soup and makes all the difference
Step-by-Step Instructions
- Preheat Oven and Prep Dish:
- Set oven to three hundred fifty degrees and lightly butter or grease a nine by thirteen baking dish This prevents sticking and helps crisp the edges
- Mix Cheese:
- Combine grated cheddar and Monterey Jack in a small bowl Toss together to ensure even distribution for every bite
- Prepare Potatoes:
- In a very large bowl toss defrosted hash browns with melted butter salt and pepper Make sure every piece is well coated
- Add Creaminess:
- Stir in sour cream and most of the grated cheese mixture Save a bit for the topping later The potatoes should look rich and creamy at this stage
- Make Creamy Sauce:
- Melt butter in a large skillet over medium heat Add diced onions and cook until translucent about four to five minutes Stir in minced garlic and cook for another minute until fragrant Sprinkle flour over the mixture Stir it in and cook for another minute to eliminate any raw taste
- Simmer and Thicken:
- Slowly whisk in chicken broth making sure it blends smoothly with no lumps Then whisk in milk Continue cooking while whisking until the sauce thickens in about three to four minutes Season with salt and pepper and remove from heat
- Combine Everything:
- Pour the hot cream sauce over the potato mixture Gently fold until evenly mixed The heat from the sauce melts the cheese for an extra creamy finish Transfer everything to the prepared baking dish and level the mixture
- Add Toppings:
- Sprinkle the reserved cheese over the potatoes For the crunch combine melted butter and crushed cornflakes in a bowl Mix until coated and spread evenly across the casserole
- Bake:
- Cover loosely with foil and bake for twenty minutes Remove the foil and bake another fifteen to twenty minutes or until the edges are bubbling and the cornflakes are deeply golden brown Rest for ten minutes before slicing This helps the casserole firm up for serving

Storage Tips
Once the casserole is cool cover it tightly with foil or transfer to airtight containers It will keep in the fridge for up to four days If you want to freeze just portion it out once cooled and wrap or seal tightly Reheat in the oven for the best crispy topping or microwave for a quick lunch
Ingredient Substitutions
You can swap in Greek yogurt for sour cream if needed and use any melty cheese you like such as Colby or mozzarella For the topping try crushed Ritz crackers or panko breadcrumbs if cornflakes are not handy Rotisserie chicken stirred in also turns this into a main dish
