Step‑by‑Step Instructions for Cheesy Potato Casserole with French Onion Dip Step 1: Preheat the Oven and Prepare the Pan Preheat your oven to 350°F (175°C) and grab a 9×13-inch baking pan. Grease the pan generously with butter or cooking spray to prevent sticking, ensuring that every bite of your Cheesy Potato Casserole with French Onion Dip comes out perfectly! A well-prepared pan will help achieve that delightful golden-brown crust. Step 2: Sauté the Onions In a skillet over medium-low heat, melt 2 tablespoons of butter. Add in the diced onion and sauté until it becomes translucent, about 5-7 minutes. Stir occasionally to ensure even cooking without browning. This step brings out the sweetness, infusing your casserole with a warm, comforting flavor that sets the stage for the rest of the dish. Step 3: Mix the Casserole Base In a large mixing bowl, combine the sautéed onions, garlic powder, cream of chicken soup, French onion dip, salt, and black pepper. Stir thoroughly until the mixture is smooth and well-blended. This creamy base is what makes your Cheesy Potato Casserole with French Onion Dip so irresistible, setting a delicious foundation for the crispy top that’s to come. Step 4: Incorporate the Hashbrowns Gently fold in the frozen hashbrowns to the creamy mixture, ensuring they are evenly coated. This should take about 1-2 minutes. Once all the hashbrowns are well mixed, transfer the mixture into your greased baking pan, spreading it evenly to ensure consistent cooking. This step is crucial for a rigid structure and delightful texture in your dish. Step 5: Add the Cheese Sprinkle the shredded sharp cheddar cheese evenly over the hashbrown mixture. This cheesy layer will melt into a gooey goodness as it bakes, creating a mouthwatering experience in each bite of your Cheesy Potato Casserole with French Onion Dip. Make sure to cover all corners so every bite is bursting with flavor! Step 6: Prepare the Crunchy Topping In a small bowl, melt the remaining 4 tablespoons of butter, then mix in the crushed cornflakes until thoroughly coated. Spread this mixture evenly over the cheese, creating a delightful crispy topping for your casserole. The crunch of the cornflakes against the creamy potatoes will elevate your dish, making it visually appealing and texturally satisfying. Step 7: Bake to Perfection Place your assembled casserole in the preheated oven and bake for 50-60 minutes. Keep an eye on it, and look for the cheese to bubble and the cornflake topping to turn golden brown. The potatoes should be soft when poked with a fork. This is the moment when your home will be filled with a heavenly aroma, signaling that dinner is almost ready! Step 8: Let It Rest Before Serving Once baked, remove the casserole from the oven and allow it to rest for about 5 minutes. This resting period will help the casserole set slightly, making it easier to serve.
