How to Make Loaded Mashed Potato Casserole Recipe
Step 1: Preheat and Prepare
Start by heating your oven to 375°F (190°C). This ensures the oven is at the perfect temperature to melt the cheese and crisp up the bacon while keeping the potatoes luscious inside.
Step 2: Combine the Creamy Base
In a large mixing bowl, blend together your mashed potatoes, sour cream, milk, butter, salt, and pepper. This mixture forms the silky, flavorful foundation of your casserole, so mix until smooth and fully combined.
Step 3: Add Cheese and Bacon
Fold in half of your shredded cheddar cheese and crumbled bacon. This infuses the casserole with its signature savory notes and luscious pockets of cheese that will melt deliciously in the oven.
Step 4: Assemble the Casserole
Spread the combined potato mixture evenly into your chosen baking dish, creating a lovely thick layer. Then, sprinkle the remaining cheese and bacon over the top — this layer will melt and brown nicely, giving a stunning finish.
Step 5: Bake to Perfection
Place your dish in the oven and bake for 20 to 25 minutes. You’re looking for the cheese to fully melt and bubble, creating a golden crust that invites you to dig right in.
Step 6: Garnish and Serve
Once out of the oven, generously scatter the fresh green onions over the top. They’ll add just the right crunch and a fresh flavor burst that perfectly balances the richness of the casserole.

Side Dishes
