Creamy, cheesy, and topped with crispy bacon, it’s the perfect holiday side dish or a hearty addition to any family dinner. Think of it as your favorite baked potato, but in a rich, indulgent casserole form.
Ingredients:
- 6 large russet potatoes, peeled and diced
- 1 cup sour cream
- 1 cup mayonnaise
- 2 cups shredded cheddar cheese, divided
- ½ cup shredded mozzarella cheese
- 6 strips cooked bacon, crumbled
- 3 green onions, thinly sliced
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- 1 teaspoon salt (adjust to taste)
- ½ teaspoon black pepper
- 2 tablespoons butter
Step-by-Step Instructions
Step 1: Prepare the Potatoes
Preheat your oven to 375°F (190°C). Peel and dice the russet potatoes into bite-sized cubes. Place them in a large pot of salted water and boil for 10–12 minutes, or until fork-tender but not mushy. Drain well.
Step 2: Mix the Creamy Base
In a large mixing bowl, combine sour cream, mayonnaise, half of the shredded cheddar cheese, mozzarella cheese, garlic powder, onion powder, salt, and pepper. Stir until smooth and creamy.
Step 3: Combine & Layer
Add the cooked potatoes into the creamy mixture and fold gently until all the potatoes are well-coated. Transfer everything into a greased 9×13-inch baking dish.
Step 4: Add the Toppings
Sprinkle the remaining cheddar cheese evenly over the top. Add crumbled bacon for that classic loaded potato flavor.
Step 5: Bake to Perfection
Place the casserole in the preheated oven and bake uncovered for 25–30 minutes, or until bubbly and golden brown on top.
Step 6: Garnish & Serve
Once baked, remove from the oven and let cool for 5 minutes. Sprinkle freshly sliced green onions on top before serving.
Serving Suggestions
This loaded potato casserole pairs beautifully with roasted chicken, grilled steak, or even as part of your Thanksgiving or Christmas dinner spread. It’s also a crowd-pleaser for potlucks and weekend family dinners.
