Ingredients You’ll Need

4 pounds russet or Yukon gold potatoes: These starchy potatoes create a fluffy texture perfect for mashing. You can also use other varieties, but russets or Yukons are the best for this dish.
1 teaspoon salt, or to taste: Salt enhances flavor, so adjust based on your preference.
½ teaspoon black pepper: Adds a subtle heat that balances the richness of the other ingredients.
½ cup unsalted butter, melted: Using unsalted butter gives you control over the overall saltiness of the casserole.
1 cup sour cream: For creaminess and a slight tang, sour cream is a must.
4 ounces cream cheese, softened: This adds richness and creaminess, ensuring a smooth texture throughout.
1 teaspoon garlic powder: A great way to add depth of flavor without the hassle of fresh garlic.
1 teaspoon onion powder: Like garlic powder, it brings in aromatic flavor to elevate the overall taste.
2 cups shredded sharp cheddar cheese, divided: Cheddar brings that sharp, nutty flavor and gooey texture when melted.
8 slices bacon, cooked and crumbled, divided: Bacon adds a delicious crunch and smokiness. Feel free to swap it with turkey bacon if you want a lighter option.
¼ cup sliced green onions, divided: Green onions brighten the dish and give it a fresh finish.

How to Make Loaded Twice Baked Potato Casserole

Prep the Potatoes: Peel the potatoes and cut them into evenly sized chunks. This ensures even cooking. Place them in a large pot and cover them with cold water.
Cook the Potatoes: Bring the pot to a boil over medium-high heat. Cook for 15 to 20 minutes, or until the potatoes are very tender and easily pierced with a fork.
Mash the Potatoes: Drain the potatoes thoroughly and let them sit for 1 to 2 minutes for extra steam to escape. Mash just until smooth. You should have around 8 cups of mashed potatoes.
Preheat the Oven: Set your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
Mix Ingredients: In a large mixing bowl, add the mashed potatoes. Stir in the salt, black pepper, melted butter, sour cream, cream cheese, garlic powder, and onion powder until smooth and creamy.
Add the Goodies: Gently fold in 1½ cups of the shredded sharp cheddar cheese, 6 slices of crumbled bacon, and 3 tablespoons of sliced green onions until everything is evenly combined.
Spread in Baking Dish: Transfer the potato mixture to the greased baking dish and spread it out evenly.
Top with Cheese: Sprinkle the remaining ½ cup of cheddar cheese evenly over the top for that golden, melty finish.
Add More Bacon: Sprinkle the remaining crumbled bacon on top, giving it extra flavor and crunch.
Bake: Bake uncovered for 25-30 minutes, or until the casserole is hot throughout and the cheese is beautifully melted.
Garnish: Sprinkle with the remaining sliced green onions just before serving for a fresh touch.
Optional Broil: If you desire a golden, crispy top, broil the casserole for 2-3 minutes right before serving. Keep a close eye during this step!

Storing & Reheating

If you have leftovers (which is rare with this casserole!), let it cool completely before storing it in an airtight container. It will keep in the refrigerator for up to 3-4 days. For longer storage, you can freeze it for up to 3 months. When reheating, simply place it in the oven at 350°F (175°C) for about 20 minutes, or until heated through. The texture may change slightly, so adding a little extra cheese on top before reheating can help renew that creamy goodness.

Chef’s Helpful Tips

Avoid common mistakes by ensuring you don’t over-mash the potatoes; a few lumps add texture.
Use room temperature cream cheese for smoother mixing; it blends better into the hot mashed potatoes.
If you’re short on time, consider microwaving the potatoes instead of boiling—just make sure to cover them to steam properly!
For an added flavor boost, try mixing in some smoked cheese with the cheddar.
You can prep this casserole ahead of time; simply assemble the ingredients and store it in the refrigerator until you’re ready to bake.
