What Is The Difference Between Baked Potato And Twice Baked Potato?

A Baked Potato is cooked whole or in halves until soft inside with a crispy skin. It’s then typically served with simple toppings like shredded cheese, sour cream, and bacon.

A twice-baked potato involves baking, halving, and scooping out the inside, which is mixed with other ingredients, refilled into the skin, and baked again for a crispy top and creamy interior. 

So, What Is A Twice-Baked Potato Casserole?

Twice-Baked Potato Casserole deconstructs the elements of a twice-baked potato and reassembles them into one dish!

This casserole takes the flavors and ingredients of twice-baked potatoes — like cheese, sour cream, and bacon — and combines them in a baking dish–then bakes until hot and bubbly. Essentially, you get the creamy texture and amazing flavors of twice-baked potatoes in a form that’s easier to serve to a group, and perfect for hosting or for the holidays!

If you’ve had Sam’s Club Twice Baked Potatoes, this recipe uses similar ingredients — potatoes, cheese, sour cream, and bacon!

A composition of fresh ingredients for this recipe.

Twice-Baked Potato Casserole Ingredients

  • Gold potatoes: Choose potatoes that are firm and free of sprouts, green areas, or blemishes for the best flavor and texture.
  • Fine sea salt: We’ll use the salt when seasoning the boiling water for the potatoes and again in the dish itself.
  • Unsalted butter: Opt for unsalted to control the sodium content of your dish.
  • Whole milk or cream: Use whole milk for a lighter texture or cream for richer smoothness. Whenever we’re serving to a crowd, we’ll use cream!
  • Sour cream: This adds tanginess and creaminess; a full-fat version contributes to a richer flavor.
  • Garlic powder: Provides a subtle hint of garlic flavor. Leave it out if you aren’t a fan!
  • Bacon: Cook until crispy for added texture. We like fixing bacon in the oven to keep the mess contained!
  • Green onions: Add a fresh, crisp bite; use both white and green parts for contrast in flavor.
  • Sharp Cheddar cheese: I recommend grating your own cheese for better melting and flavor; sharp Cheddar provides a more intense, stronger flavor, but medium and mild will also work here!

How To Make Twice-Baked Potato Casserole

  • Bacon prepping: Bake slices on a rack over a foil-lined tray until crisp; this method helps fat drip away, ensuring crispy, less-greasy bacon.
  • Potato boiling: Cube potatoes uniformly for even cooking. Start in cold, salted water for even heating and better seasoning.
  • Mixture creaming: Combine butter, sour cream, and milk (or cream) on low heat until smooth; warming dairy ingredients over low heat ensures nothing curdles!
  • Potato mashing: Use a ricer for fluffier potatoes or a masher for a heartier texture. Avoid overworking to prevent gumminess.
  • Mix-In Adding: Gently fold in cheese, bacon, and green onions, reserving some for topping; these mix-ins provide texture and flavor in every bite — just like a twice-baked potato!

Let Me Convince You to Use a Ricer!

I’ve dedicated years to creating the ultimate Mashed Potatoes, and the game-changer? A ricer! It’s the secret to the fluffiest, creamiest, most divine mashed potatoes. Blenders, food processors, or hand mixers tend to overdo it, turning your spuds into a gloopy mess. And since mashed potatoes are the base of this Twice-Baked Potato Casserole, we want to avoid the common potato pitfalls.

But a ricer gives you perfect consistency without the gluey aftermath. And it’s not just efficient—it’s fun, like playing with grown-up play-dough! If mashed potatoes are your jam, don’t miss out on the magic of using a ricer! (P.S. There are loads of other uses that go beyond potatoes for a ricer!)

Other Tools

  1. Large sheet pan: For baking bacon.
  2. Large cooling rack: Also for baking bacon. Place bacon on the rack while baking for even crispiness.
  3. Aluminum foil: For lining the sheet pan for easy cleanup.
  4. Large pot: For boiling potatoes.
  5. Strainer: To drain potatoes after boiling.
  6. Knife and cutting board: For cubing potatoes and chopping bacon and green onions.
  7. Potato masher: If you don’t have a ricer!
  8. Wooden spoon: For mixing ingredients without overworking the potatoes.
  9. Casserole dish: For assembling and baking the Twice-Baked Potato Casserole.

Equipment

  • 9x9-inch or 7x11-inch casserole pan (Note 1)

Ingredients

  • 12 slices (12 oz.) bacon
  • 3 pounds gold potatoes, cut to 1-inch cubes (8 cups)
  • Fine sea salt and pepper
  • 8 tablespoons unsalted butter
  • 1 cup heavy cream (or whole milk)
  • ¾ cup sour cream
  • ½ teaspoon garlic powder
  • 1 bunch green onions, separated
  • cups (10.5 oz) grated sharp Cheddar cheese, divided (Note 2)

Instructions

  • BACON: Preheat oven to 400°F. Line a large sheet pan with foil and place a greased cooling rack on top. Lay bacon slices evenly on the rack without overlapping. Bake for 15-25 minutes or until crisp. Note: Bacon will become crisper as it cools. Once cooled, set aside 3 slices for topping and dice the rest.

  • POTATOES: Meanwhile, peel potatoes and cube into 1-inch pieces. Add to a large pot and cover by 1 inch with cold water. Add 1 tbsp salt. Bring to a boil; then reduce to a rapid simmer and cook until potatoes are easily pierced with a fork, 15-20 minutes. Drain potatoes in a strainer and let dry for 5 minutes.

  • CREAM MIXTURE: In the same pot used for boiling potatoes, set to low heat. Add butter, sour cream, milk or cream, garlic powder, 1 teaspoon salt, and pepper to taste (I add ½ tsp). Stir until smooth and then remove from heat.
  • MASH POTATOES: While the potatoes are still hot, pass them through a ricer directly into the cream mixture. If you don't have a ricer, gently mash with a potato masher. (Avoid blending or beating the potatoes, as this can make them gluey.) Stir with a wooden spoon until smooth.
  • ASSEMBLE AND BAKE: To the mashed potatoes, add the diced bacon (excluding the portion set aside for topping), 2 cups of cheddar cheese, and ½ cup of finely sliced green onions. Mix gently. Transfer the mixture to a casserole dish, (You may not be able to fit it all -- don't overfill -- See Note 1.) and smooth the surface. Sprinkle with the remaining ½ cup of cheese and reserved diced bacon. Cover the dish loosely with foil. Place the casserole dish on a sheet pan and bake in the preheated oven for 20 minutes. Remove the foil and continue baking for an additional 10 minutes. Once done, garnish with 2 tablespoons of sliced green onions. Serve and enjoy while hot!

Recipe Notes

Note 1: Casserole dish: After testing with 8x8, 9x9, and 7x11-inch pans, we found the 9x9 to be the best. Be mindful not to overfill your dish; the potatoes do rise and may spill over (leave a ½-inch border at the top). If you have excess and it won't fit nicely in the casserole dish, enjoy it as a side of mashed potatoes!
Note 2: Cheddar: Sharp Cheddar is our preference flavor-wise, but medium or mild works too. For the best texture, grate the cheese yourself; pre-shredded can make the casserole greasy. When measuring, pack the cheese gently into the cup to ensure the correct amount. You'll need just under 11 oz. for this recipe.
