What You Need To Make This Loaded Twice Baked Potato Casserole Recipe?
Russet Potatoes: These are the best for baking because they’re starchy and get perfectly fluffy inside. Plus, they hold up really well with all the mix-ins. Just make sure they’re scrubbed clean since we’re baking them with the skins on.
Olive Oil: A little rub of olive oil helps crisp up the potato skins and adds a nice roasted flavor. It’s a small touch, but it makes a big difference.
Bacon: Let’s be real—bacon is what takes this casserole over the top! Go for crispy bacon so it adds a little crunch. Save some for sprinkling on top; it’s all about that finishing touch.
Sharp Cheddar Cheese: Sharp cheddar has a punchy flavor that really stands out. It melts beautifully and gives the dish that classic loaded potato taste. Mild cheddar works too, but sharp is what really brings the “wow” factor.
Mayonnaise and Sour Cream: These two are what make the casserole creamy and tangy. Sour cream adds that fresh tang, while mayo brings a little extra richness. Trust me, they’re the secret to making this dish extra indulgent.
Green Onions: Green onions add a fresh, slightly zesty flavor that lightens up the whole dish. They’re perfect in the mix and sprinkled on top for a pop of color and brightness.
Kosher Salt and Black Pepper: Keep it simple here! A little bit of salt and freshly ground black pepper is all you need to bring out the best in each ingredient.
Steps To Make Loaded Twice Baked Potato Casserole:
Preheat the Oven: Set your oven to 400°F, and give a 9×9-inch baking dish a light spray with nonstick spray so nothing sticks later on.
Bake the Potatoes: Rub each potato with a little olive oil and sprinkle with salt, then pop them on a baking sheet or straight on the oven rack. Bake until they’re nice and tender, about 45-60 minutes. Flip them halfway through for even cooking. Let them cool for about 15 minutes so you can handle them, then lower the oven to 350°F.
Chop and Mix: Once the potatoes are cool enough, cut them into bite-sized pieces and toss them in a big mixing bowl.

Add the Creamy Goodness: Add the sour cream and mayonnaise to the potatoes and mix gently until everything’s coated and creamy.
Load Up the Casserole: Add 1 1/2 cups of the cheddar cheese, three-quarters of the green onions, and three-quarters of the bacon to the bowl. Stir until everything’s nicely combined.
Assemble and Top: Spread the potato mixture into your baking dish, then sprinkle the remaining cheddar cheese and bacon on top.
Bake it Up: Cover the dish with foil and bake for 20 minutes. Remove the foil, then bake for another 10 minutes or so until the cheese is all melted and bubbly.
Finish and Serve: Take it out, sprinkle the remaining green onions on top for a fresh touch, and serve it up warm. Dig in and enjoy!
Tip:
Alright, here’s the secret to making this casserole the best it can be: go for sharp cheddar and don’t skimp on the bacon! Sharp cheddar has that punchy flavor that really stands out against the creamy sour cream and mayo, giving each bite a nice, balanced flavor. And the bacon? Make it extra crispy before adding it in—it gives the perfect crunchy texture to go with those soft, creamy potatoes. Want to give it a little extra something? Try tossing in a pinch of garlic powder or smoked paprika; it adds a subtle kick and makes the whole dish feel a bit more special.
Frequently Asked Questions:
Can I make this casserole ahead of time?
Absolutely! You can prepare the casserole up until the baking step, then cover it and store it in the fridge for up to 24 hours. When you’re ready to bake, just pop it in the oven as directed. If it’s coming straight from the fridge, you may need to add an extra 5-10 minutes to the bake time.
Can I use a different cheese?
Of course! While sharp cheddar gives that classic loaded potato taste, you can mix it up with other cheeses. Monterey Jack, Colby, or even a bit of mozzarella all work well. Just make sure it’s a cheese that melts nicely for that gooey finish.
How should I store leftovers?
Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat, pop a portion in the microwave or warm the whole dish in the oven at 300°F until heated through. This way, it stays creamy and delicious!
