Step‑by‑Step Instructions for Easy Cheesy Baked Potato Casserole That Feels Like Home
Step 1: Prepare the Potatoes
Start by peeling and cubing 4 to 5 medium russet potatoes. Place them in a large pot of cold water, ensuring they’re fully submerged. Bring the water to a rolling boil and cook the potatoes for about 15 minutes or until they’re fork-tender. This step creates the creamy base for your Easy Cheesy Baked Potato Casserole.
Step 2: Mash the Potatoes
Once the potatoes are tender, drain them thoroughly and return them to the pot. Add melted butter, sour cream, and milk, then gently mash the mixture until smooth and creamy. Incorporate garlic powder, salt, and black pepper for seasoning. The result should be a luscious, creamy texture that sets the foundation for your casserole.
Step 3: Mix in the Cheeses
Fold in the shredded sharp cheddar and mozzarella cheeses, alongside the chopped green onions, ensuring everything is evenly combined. This blend not only adds a rich, cheesy flavor but also transforms your mixture into a decadent filling for the Easy Cheesy Baked Potato Casserole.
Step 4: Transfer to Casserole Dish
Lightly grease a 9×13-inch casserole dish with cooking spray or butter. Carefully transfer the cheesy potato mixture into the dish, using a spatula to smooth the top evenly. This step helps create a beautiful presentation while ensuring that every bite is packed with flavor.
Step 5: Bake the Casserole
