Twice Baked Potato Casserole

Prep Time 30 minutes
Cook Time 35 minutes
Servings 12


  • 5 lbs potatoes
  • 1 teaspoon salt
  • 2 teaspoons garlic salt
  • 2 teaspoons garlic powder
  • 1 teaspoon black pepper
  • 16 ounces sour cream
  • 4 tablespoons butter
  • 1/2 cup milk
  • 1 pound cooked and crumbled bacon
  • 4 cups shredded cheddar cheese
  • 1/4 cup chopped green onions - optional


  • Peel and cut potatoes into chunks. If using red potatoes, no need to peel. Boil potatoes in a large pot with 1 teaspoon salt approximately 30 minutes or until very tender and ready to mash.
  • Drain potatoes. Place back in the pot, Add the butter, sour cream, garlic salt, garlic powder, and pepper.
  • Mash and mix everything together.
  • Add a milk a little at a time as needed to get creamy. You want it to be thick but not too thick.
  • Once potatoes are mashed and mixed, spray a 9×13 inch casserole dish with cooking sprat. Add half the potato mixture to the bottom of the pan and sprinkle the top with 1 cup of cheese and half of the bacon.
  • Top with the remainder of the potato mixture and top with cheese and bacon.
  • Bake covered with foil in a preheated 350 degree oven for 25 minutes. Uncover and bake another 5 to 10 minutes or until warm and bubbly. Top with green onions if you want before serving.


You can make this up to 3 days ahead and cover and refrigerate until ready to bake.   If baking out of the fridge it may take 45 minutes to an hour. Sometimes I use a packet of dry ranch dressing mix  instead of the garlic powder & garlic salt and that is really good too. I make these for pot lucks and there’s never a spoonful left.
