Step‑by‑Step Instructions for Creamy Red Potato Casserole with Crunchy Corn Flake Topping
Step 1: Prepare the Potatoes
Begin by washing the red potatoes thoroughly under cold water. Cut them into large, bite-sized pieces to ensure even cooking. Place the potato chunks in a large pot and fill it with salted water until they are fully submerged. Bring the water to a boil over medium-high heat, then reduce to a simmer, cooking until the potatoes are fork-tender, about 20-25 minutes.
Step 2: Preheat the Oven
While the potatoes are boiling, preheat your oven to 350°F (175°C). This step is crucial as it allows the oven to reach the perfect temperature for baking your creamy red potato casserole. Once preheated, prepare a 9x13-inch baking dish by greasing it lightly with cooking spray or butter to prevent sticking during baking.
Step 3: Prepare the Crunchy Topping
In a medium-sized bowl, combine the corn flakes with melted butter, mixing well until all flakes are coated. This buttery mixture will create a deliciously crunchy topping on your casserole. Set the bowl aside as you gather the other ingredients for the creamy filling of the casserole.
Step 4: Mix the Casserole Filling
Once the potatoes are fork-tender, drain them thoroughly and return them to the pot. In a large mixing bowl, combine the drained potatoes with sour cream, ranch dressing, crumbled bacon, and one cup of shredded sharp cheddar cheese. Gently mash the mixture with a fork or potato masher until it’s well mixed but still has some chunks for texture.
Step 5: Assemble the Casserole
Transfer the creamy potato mixture into your greased baking dish, spreading it evenly. This creamy red potato casserole will form the delicious base layer. Level the mixture with a spatula, ensuring it fills the dish uniformly for even baking.
Step 6: Add Cheese and Topping
Sprinkle the remaining cup of shredded cheddar cheese evenly over the potato mixture, adding an extra layer of rich flavor. Next, evenly disperse the buttered corn flake mixture over the cheese, ensuring every corner is covered for the ultimate crunchy topping.
Step 7: Bake the Casserole
Place the baking dish in your preheated oven and bake uncovered for 20-30 minutes. The casserole is ready when the cheese is melted and bubbly and the corn flakes have turned a beautiful golden brown. Keep an eye on it to avoid over-browning.
Step 8: Serve the Dish
After baking, remove the casserole from the oven and let it cool for a few minutes to set. Serve this delightful creamy red potato casserole warm, offering a perfect combination of creamy texture and crispy topping that’s sure to be a hit at your table!

Make Ahead Options
These Creamy Red Potato Casserole preparations are perfect for busy weeknights! You can prepare the creamy potato mixture up to 24 hours in advance by mixing the drained potatoes with sour cream, ranch dressing, crumbled bacon, and shredded cheese. Store it in an airtight container in the refrigerator until you're ready to bake. To maintain the delicious quality, avoid adding the corn flake topping until just before baking. When you’re ready to serve, transfer the potato mixture to a greased baking dish, top with cheese and corn flakes, and bake it in your preheated oven for 20-30 minutes. This way, you enjoy that satisfying crunch and creaminess with minimal effort!

Red Potato Casserole Recipe FAQs
How do I choose the best red potatoes?
Absolutely! When selecting red potatoes, look for firm, smooth ones without any dark spots or blemishes. The skin should be a vibrant red color. Avoid potatoes that feel soft or have sprouted eyes, as these are signs of age.
How do I properly store leftovers?
You can store leftovers in an airtight container in the fridge for up to 3 days. This ensures they remain fresh and delicious! When reheating, I recommend using the oven to maintain that delightful crunch on top—simply cover with foil, heat at 350°F (175°C) for about 20 minutes, and uncover for the last few minutes.
Can I freeze the Red Potato Casserole?
Yes, you can! To freeze your unbaked Red Potato Casserole, wrap it tightly with plastic wrap and aluminum foil. It will keep well in the freezer for up to 2 months. When you're ready to bake it, place it in the fridge to thaw overnight, then add your corn flakes and bake at 350°F (175°C) for about 30-40 minutes, until heated through.
What if my casserole is too watery?
Very good question! If your casserole turns out watery, it could be due to excess moisture in the potatoes. You can prevent this by ensuring the potatoes are well-drained after boiling. If it happens, a quick fix is to bake the casserole uncovered for an additional 10-15 minutes to help evaporate the excess liquid.
Can I make this casserole gluten-free?
Yes, indeed! To cater to a gluten-free diet, simply use gluten-free corn flakes for the topping. Moreover, check your ranch dressing for any gluten-containing ingredients. Making these small adjustments allows everyone to enjoy this comforting dish!
Is this casserole pet-friendly?
It's great that you're thinking about your furry friends! However, this casserole contains ingredients like onion (in ranch dressing) and dairy, which can be harmful to pets. It's best to keep this delicious dish for human enjoyment only.
