How to Make Cheesy Potato Casserole Recipe
Step 1: Preheat Your Oven
Start by setting your oven to 350°F (175°C). This ensures a steady, even heat for baking your casserole so it cooks through without drying out or burning.
Step 2: Mix the Potato Base
In a 9×13-inch casserole dish, combine the shredded potatoes, condensed cheddar cheese soup (or cream of mushroom soup), shredded cheddar cheese, sour cream, melted butter, milk, garlic powder, and onion powder. Stir everything thoroughly to make sure the flavors meld and the potatoes are evenly coated with all those delicious creamy ingredients.
Step 3: Prepare the Topping
Place the cornflakes into a small bowl, gently breaking them into smaller pieces without pulverizing. Toss the cornflakes with 2 tablespoons of melted butter until every flake is glistening. This step is key to achieving that irresistible crisp and golden finish.
Step 4: Assemble the Casserole
Evenly sprinkle the buttered cornflakes over the potato mixture in your casserole dish. The crunchy topping will add stunning texture contrasts once baked.
Step 5: Bake to Perfection
Bake the assembled casserole uncovered for 35 to 40 minutes. You’ll know it’s ready when the edges bubble up with cheesy deliciousness and the cornflake topping turns a mouthwatering golden brown. Let it cool just a bit before serving for the best results.
How to Serve Cheesy Potato Casserole Recipe

Garnishes
Fresh green onions or chopped chives add a vibrant, fresh pop of color and flavor that complements the richness of the casserole. A light sprinkle of paprika can also elevate its appearance and introduce a subtle smoky note.
Side Dishes
This dish pairs beautifully with green vegetables like steamed broccoli or roasted asparagus, which provide a crisp, healthy counterbalance. For meat lovers, roasted chicken or a juicy steak make wonderful companions for this hearty casserole.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins for easy portioning and an elegant touch. Alternatively, layer it with cooked bacon bits or sautéed mushrooms in the middle to surprise guests with extra layers of flavor.
Make Ahead and Storage
Storing Leftovers
After enjoying your Cheesy Potato Casserole Recipe, simply cover leftovers with plastic wrap or transfer to an airtight container. Refrigerate for up to 3 days, keeping the flavors fresh and ready for another satisfying meal.
Freezing
This casserole freezes wonderfully. Assemble the dish but don’t bake it, then wrap tightly with foil before freezing. When you’re ready, thaw overnight in the fridge and bake as instructed, adding a few extra minutes to the cook time if needed.
Reheating
To bring back that freshly baked warmth, reheat portions in the oven at 350°F (175°C) for about 15 minutes or until bubbly. You can also microwave smaller servings, but oven reheating maintains the crispy topping best.
FAQs
Can I use fresh potatoes instead of shredded frozen ones?
Absolutely! Freshly shredded potatoes work beautifully. Just be sure to squeeze out excess moisture after shredding to avoid a soggy casserole.
Is there a substitute for the condensed cheddar soup?
If you prefer, cream of mushroom soup is a fantastic alternative, offering a milder flavor that still blends well with the other ingredients.
Can I make this recipe vegetarian?
This recipe is naturally vegetarian as long as you use vegetarian-friendly cheese soup or the cream of mushroom option and cheese that fits your dietary needs.
How can I make the topping more flavorful?
Try mixing in some grated Parmesan or smoked paprika with the cornflakes before baking to deepen the flavor and enhance the crunch.
What if I want to add more vegetables?
Feel free to stir in cooked peas, diced bell peppers, or even sautéed spinach to the potato mixture for added color, nutrients, and texture.
