What Makes This Special

This hashbrown casserole gets its richness from a mix of sour cream and sharp cheddar, so it’s creamy without tasting flat. A buttery, crunchy topping adds great texture and keeps the casserole from feeling too heavy. It’s also incredibly flexible—easy to make vegetarian, gluten-free, or loaded with protein.

Best of all, it can be assembled ahead and baked when you need it.

Ingredients

• 1 (30–32 oz) bag frozen shredded hashbrowns, thawed
• 1 can (10.5 oz) condensed cream of chicken soup (or cream of mushroom for vegetarian)
• 1 cup sour cream (full-fat for best texture)
• 2 cups shredded sharp cheddar cheese, divided
• 1/2 cup unsalted butter, melted
• 1 small onion, finely diced (about 1/2 cup)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1 teaspoon kosher salt (adjust to taste)
• 1/2 teaspoon black pepper
• 1 cup cornflakes, lightly crushed (or crushed kettle chips or panko)
• 2 tablespoons chopped fresh chives or parsley (optional, for garnish)
• Optional add-ins: 1 cup cooked bacon, ham, or sausage; 1 cup sautéed bell peppers; 1/2 cup sliced green onions

Step-by-Step Instructions

1. Prep the oven and pan: Heat the oven to 350°F (175°C). Grease a 9×13-inch baking dish with a little butter or cooking spray.
2. Thaw the hashbrowns: Spread them out on a sheet pan for 15–20 minutes or thaw overnight in the fridge. Remove excess moisture by patting with paper towels if wet.
3. Sauté the onion (optional but recommended): In a small skillet, cook the diced onion in a teaspoon of butter or oil over medium heat until soft and slightly golden, 4–6 minutes. Let cool slightly.
4. Mix the base: In a large bowl, whisk together the condensed soup, sour cream, melted butter (reserve 2 tablespoons for the topping), garlic powder, onion powder, salt, and pepper.
5. Fold in the good stuff: Stir in 1 1/2 cups shredded cheddar and the sautéed onion.Add the hashbrowns and any optional add-ins, then gently fold until evenly coated.
6. Fill the dish: Spread the mixture into the prepared baking dish, smoothing the top.
7. Make the crunchy topping: In a small bowl, combine the crushed cornflakes with the reserved 2 tablespoons melted butter. Sprinkle evenly over the casserole, then add the remaining 1/2 cup cheddar on top.
8. Bake: Bake uncovered for 45–55 minutes, until the edges are bubbling and the top is golden brown. If the top browns too fast, tent loosely with foil.
9. Rest and serve: Let it sit for 10 minutes so it sets.Garnish with chives or parsley and serve warm.

Storage Instructions

• Refrigerate: Cool completely, cover, and store for up to 4 days. Reheat at 325°F, covered, for 15–20 minutes, then uncover for 5 minutes to crisp the top.
• Freeze unbaked: Assemble without the topping, wrap tightly, and freeze for up to 2 months. Thaw overnight, add topping, and bake as directed.
• Freeze baked: Portion into airtight containers and freeze up to 2 months.Reheat covered at 325°F until hot; add a fresh sprinkle of cheese or crumbs to revive the crunch.

Health Benefits

While this is a comfort classic, you can make it more balanced without losing flavor. Potatoes provide potassium and vitamin C, and using sharp cheddar means you can use less cheese while keeping bold flavor. Adding sautéed peppers, mushrooms, or spinach boosts fiber and micronutrients.

For a lighter version, swap in Greek yogurt for some or all of the sour cream, and use reduced-sodium soup or a homemade sauce.

Common Mistakes to Avoid

• Using icy hashbrowns: Excess moisture leads to a soggy casserole. Thaw and blot dry.
• Overmixing: Stir gently to keep the potatoes from compacting and turning dense.
• Skipping seasoning: Potatoes need salt. Taste the mixture (if no raw meat add-ins) and adjust before baking.
• Forgetting texture: A crunchy topping keeps it from feeling heavy.Don’t skip it.
• Baking at too high a heat: High heat browns the top before the center heats through. Stick to 350°F and give it time.

Alternatives

• From-scratch sauce: Replace the canned soup with a quick béchamel. Melt 3 tablespoons butter, whisk in 3 tablespoons flour, cook 1 minute, then whisk in 1 1/2 cups milk or chicken broth.Simmer until thick, season well, and cool slightly before mixing.
• Vegetarian: Use cream of mushroom soup or the homemade sauce with veggie broth. Add sautéed mushrooms for depth.
• Gluten-free: Choose a certified gluten-free condensed soup or make the sauce with cornstarch. Use crushed gluten-free cornflakes or potato chips for the topping.
• High-protein: Fold in cooked turkey sausage, diced ham, or rotisserie chicken.You can also whisk 2–3 eggs into the sauce for a breakfast bake vibe.
• Spicy: Add diced jalapeños, smoked paprika, or a pinch of cayenne. Pepper Jack cheese is a great swap for cheddar.
• Different potatoes: Use cubed hashbrowns instead of shredded for a heartier bite, or grate fresh russets—just rinse, squeeze dry, and measure by weight.

FAQ

Can I make hashbrown casserole the night before?

Yes. Assemble the casserole without the topping, cover, and refrigerate overnight.

Add the topping just before baking. You may need an extra 5–10 minutes in the oven since it starts cold.

What if I only have fresh potatoes?

Peel (optional) and shred russet potatoes. Rinse in cold water to remove excess starch, squeeze very dry in a towel, and measure by weight to match the recipe.

Season a touch more, as fresh potatoes can taste flat without it.

How do I keep the topping crispy when reheating?

Reheat covered until hot, then uncover for the last 5–10 minutes. If needed, add a fresh sprinkle of crumbs tossed with a bit of melted butter right before that final uncover.

Can I use low-fat dairy?

You can, but the texture will be slightly less creamy. A good compromise is using Greek yogurt for half the sour cream and keeping regular cheese for melt and flavor.

What cheeses work best?

Sharp or extra-sharp cheddar gives the most flavor.

Monterey Jack, Pepper Jack, or a bit of Gruyère melt beautifully. Avoid pre-shredded cheese if you can, as it has anti-caking agents; freshly grated melts smoother.

How do I serve it?

It’s great as a side with roasted chicken, baked ham, or a simple green salad. For brunch, add scrambled eggs, fruit, and coffee.

A dash of hot sauce or a spoonful of salsa on top is delicious.
