How to Make Twice Baked Potato Casserole
- Prep Your Oven and Dish: Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish.
- Layer the Potatoes: Chop warm baked potatoes into bite-sized pieces. Place half of them in the prepared dish and sprinkle lightly with salt and pepper.
- Add the First Layers: Spread half of the sour cream over the potatoes. Sprinkle with half of the shredded cheddar and mozzarella cheese, then top with half of the crumbled bacon.
- Repeat the Layers: Add the remaining potatoes, then layer the remaining sour cream, cheeses, and bacon. Make sure to leave the bacon on top—it makes the casserole look irresistible.
- Bake: Place the casserole in the oven uncovered and bake for about 20 minutes, or until the cheese is fully melted and the casserole is warmed through.
- Add Finishing Touches: Sprinkle with chopped green onions before serving for a pop of color and flavor.
This recipe is best enjoyed warm and fresh from the oven, but it can also be made ahead with minor adjustments to the bake time.
Tips for the Perfect Potato Casserole
- Choose Yukon Gold Potatoes: Their thin skin and buttery flavor make them ideal for casseroles.
- Adjust Cheese and Bacon Ratios: If you love extra cheesy, creamy layers, add more cheese or bacon according to your taste.
- Using Leftover Potatoes: If your baked potatoes are cold, increase baking time slightly to ensure the casserole is heated through.
- Make Ahead Tips: Cover with foil and allow the dish to come to room temperature before baking to prevent uneven heating. Bake covered for 30 minutes and then uncovered for an additional 15 minutes if starting from a chilled dish.
- Low-Carb Alternative: Substitute cauliflower for potatoes and follow the same layering method for a keto-friendly version.
