How to Make Loaded Baked Potato Casserole Recipe

Step 1: Prepare Your Oven and Baking Dish

Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish. This simple prep ensures that your casserole cooks evenly and comes out perfectly without sticking.

Step 2: Cook the Potatoes Until Tender

Place the peeled and cubed potatoes into a large pot, cover them with salted water, and bring it all to a boil. Boil the potatoes for about 15 to 18 minutes until they are fork-tender, which means they’re soft enough to mash easily but not falling apart. Then, drain them thoroughly to avoid excess moisture in your casserole.

Step 3: Mash and Mix the Potatoes

Now the fun part—mashing! Combine the hot potatoes with butter, sour cream, milk, salt, and black pepper. Mash everything together until you achieve a smooth, creamy consistency that feels just right in your hands. This mixture forms the heart of the casserole’s irresistible texture and flavor.

Step 4: Add Cheese and Bacon to the Mash

Stir in 1 1/2 cups of the shredded cheddar cheese and half of the crumbled bacon. This melts into the potatoes, creating pockets of cheesy, smoky goodness that run throughout every bite.

Step 5: Assemble and Bake the Casserole

Spread the mashed potato mixture evenly in your prepared baking dish. Then sprinkle the remaining cheddar cheese and bacon evenly over the top. Pop the casserole into your preheated oven and bake uncovered for 25 to 30 minutes, until the cheese on top is bubbly and golden. This final bake melds all the flavors beautifully and adds a delightful golden crust.

Step 6: Garnish and Serve

Once baked, top the casserole generously with the sliced green onions. Their bright color and fresh bite make the dish visually irresistible and add a lovely balance to the rich flavors.
