Spread the mashed potatoes evenly into a greased 9×13-inch baking dish.
Add Cheese and Bacon:
Sprinkle half of the shredded cheddar cheese on top of the potatoes. Crumble half of the bacon over the cheese layer.
Repeat Layers:
If you like an extra cheesy casserole, you can layer additional cheese and bacon on top. Save some cheese and bacon for the final topping.
Step 4: Bake the Casserole
Final Topping:
Add the remaining cheddar cheese and bacon on top of the casserole. Dot small pieces of butter on top if you like a golden, crispy finish.
Bake:
Cover the casserole dish with foil and bake for about 20-25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbling with golden brown spots.
Step 5: Garnish and Serve
Garnish:
Once out of the oven, sprinkle freshly chopped parsley or chives on top. This adds color and a fresh, mild onion flavor that cuts through the richness of the casserole.
Serve Warm:
Let the casserole sit for a few minutes before serving. This helps the layers settle, making it easier to scoop.
Tips for the Perfect Loaded Potato Casserole
Choosing the Right Potatoes:
Russet potatoes create a fluffy, airy texture, while Yukon Gold potatoes give a creamy, rich consistency. For the best texture, avoid waxy potatoes like red potatoes, which can become gummy when mashed.
Using Room Temperature Ingredients:
Bring ingredients like sour cream, heavy cream, and butter to room temperature before mixing. This helps them blend more smoothly, resulting in a creamier casserole.
Avoid Over-Mixing:
Over-mixing potatoes releases more starch, which can make them gummy. Mash just until smooth for the best texture.
Extra Cheese for Crispiness:
Adding a final layer of cheese before baking creates a delicious golden crust on top. For an even crisper top, try sprinkling with Parmesan or broiling the casserole for a couple of minutes.
Experiment with Toppings:
Feel free to add other toppings like caramelized onions, sautéed mushrooms, or jalapeños for added flavor and texture.
Variations to Try
Loaded Baked Potato Style:
Add chopped green onions and a dollop of sour cream on top when serving, similar to a loaded baked potato.
Mexican-Inspired Version:
Mix in diced green chilies, add a layer of salsa, and top with pepper jack cheese. Garnish with chopped cilantro.
Breakfast Version:
Add scrambled eggs, sausage, and a bit of diced onion to the casserole for a hearty breakfast take on this dish.
Vegetarian Version:
Skip the bacon and add roasted vegetables like bell peppers, broccoli, or mushrooms for a meat-free version. Smoked paprika can add a hint of smokiness in place of bacon.
