Shopping List – Ingredients

• 2 pounds frozen shredded hash browns (thawed) or 6 cups parboiled, grated potatoes
• 1 can (10.5 oz) condensed cream of chicken soup (or cream of mushroom for vegetarian)
• 1 cup sour cream
• 1/2 cup unsalted butter, melted (divided)
• 1 1/2 cups shredded sharp cheddar cheese
• 1/2 cup finely chopped onion (or 1 teaspoon onion powder)
• 1/2 teaspoon garlic powder
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 2 cups corn flakes cereal, lightly crushed
• Optional add-ins: 4 slices cooked bacon (crumbled), 1 small can diced green chiles, 1/4 teaspoon smoked paprika, 2 tablespoons chopped chives

Cooking Instructions

1. Preheat the oven: Set to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Mix the creamy base: In a large bowl, whisk together the condensed soup, sour cream, 1/4 cup melted butter, salt, pepper, garlic powder, and onion. Stir until smooth.
3. Add potatoes and cheese: Fold in the thawed hash browns and cheddar until everything is evenly coated.If using bacon or chiles, stir them in now.
4. Spread it out: Transfer the mixture to the prepared baking dish. Smooth the top with a spatula.
5. Make the crunchy topping: In a separate bowl, combine the crushed corn flakes with the remaining 1/4 cup melted butter. Toss until the flakes glisten.
6. Top it off: Scatter the buttery corn flakes evenly over the casserole.No bald spots; you want wall-to-wall crunch.
7. Bake: Place on the center rack and bake for 40–50 minutes, until the edges are bubbling and the topping is deeply golden.
8. Rest and garnish: Let it sit for 10 minutes to set. Sprinkle with chives if you’re feeling fancy. Serve warm.

Storage Instructions

• Refrigerator: Cool completely, then cover tightly.Keeps for 3–4 days.
• Freezer (unbaked): Assemble without the corn flake topping, wrap well, and freeze up to 2 months. Thaw overnight, add topping, and bake as directed.
• Freezer (baked): Freeze portions for up to 2 months. Reheat covered at 350°F until hot; add a fresh sprinkling of corn flakes for extra crunch if needed.
• Reheating: Oven at 350°F for 15–20 minutes.For small servings, air fryer at 325°F for 6–8 minutes to revive the crunch—FYI, it works like a charm.

What’s Great About This

• Comfort food ROI: Minimal effort, maximum payoff—like the slow cooker of casseroles, but faster.
• Make-ahead magic: Assemble the night before, bake when needed, look like a time-management wizard.
• Plays well with others: Pairs with roast chicken, ham, steak, BBQ, or just a pile of green beans to keep things honest.
• Kid-approved crunch: Corn flakes lure even picky eaters. Yes, we’re shamelessly leveraging cereal psychology.

Don’t Make These Errors

• Using frozen potatoes straight from the bag: If they’re icy, your casserole waters down and turns mushy. Thaw and pat dry.
• Skimping on butter in the topping: That fat is your crunch contractor.Without it, the flakes taste dusty.
• Overbaking: Golden brown is perfect; dark brown means dry potatoes and sad cheese. Keep an eye after 40 minutes.
• Piling on watery add-ins: Drain chiles, don’t add raw veggies with high moisture, and avoid low-fat sour cream that can curdle.
• Wrong pan size: A smaller dish leads to soggy middle; a 9×13 gives you ideal surface area for maximum crunch-to-cream ratio.

Variations You Can Try

• Southwest Kick: Add green chiles, pepper jack cheese, a pinch of cumin, and a drizzle of hot sauce.
• Loaded Baked Potato: Mix in bacon, extra cheddar, and top with chives and a dollop of sour cream when serving.
• French Onion Upgrade: Use cream of mushroom soup, caramelized onions, Gruyère, and a whisper of thyme.
• Buffalo Ranch: Stir 2–3 tablespoons buffalo sauce into the base and swap cheddar for Monterey Jack; drizzle ranch before serving.
• Smoky BBQ: Add smoked paprika, sharp cheddar, and diced smoked sausage. It’s like a backyard cookout in a pan.
• Vegetarian Mushroom: Cream of mushroom soup, sautéed creminis, and Swiss cheese for an earthy twist.

FAQ

Can I use fresh potatoes instead of frozen hash browns?

Yes.

Parboil whole potatoes until just tender, cool, grate, and pat dry. Aim for about 6 cups. The key is removing excess moisture, so your casserole stays creamy, not watery.

What can I use instead of corn flakes?

Crushed Ritz crackers, buttery panko, or even crushed kettle chips work.

If swapping, still mix with melted butter to get that shattering crust.

How do I make this gluten-free?

Use a gluten-free condensed soup (or make a quick roux with GF flour), verify your corn flakes are GF, and check seasonings. The rest is naturally safe.

Can I lighten it up without losing flavor?

Use light sour cream, cut butter by a couple tablespoons, and go half-and-half with cheddar and part-skim mozzarella. Still tasty, still cozy, just a little less extra.

How do I avoid a bland casserole?

Season the creamy base generously.

Add 1 teaspoon kosher salt, black pepper, garlic powder, and consider smoked paprika or a splash of hot sauce. Cheese with personality (sharp cheddar) helps a ton.

Is this good for brunch?

Absolutely. Serve with scrambled eggs, fruit, and coffee.

It’s a “set-and-forget” centerpiece that feeds early birds and late risers without drama.

Can I assemble and freeze ahead of a holiday?

Yes—assemble without the corn flake topping, wrap tightly, and freeze. Thaw overnight in the fridge, add topping, and bake. Your future self will high-five you.
