  • 6 medium to large potatoes (Russet or Yukon Gold)
  • 4 tablespoons unsalted butter
  • ¾ cup sour cream
  • ½ cup whole or 2% milk
  • ½ teaspoon onion powder
  • ½ teaspoon garlic powder
  • ½ teaspoon salt
  • ¼ teaspoon fresh ground black pepper
  • 1 cup shredded sharp cheddar cheese
  • 1 cup shredded Monterey Jack cheese
  • 8 slices bacon, cooked crispy and crumbled
  • 4 green onions, chopped


Step 1: Prepare the Potatoes

  1. Preheat Oven:
    • Preheat your oven to 400°F (200°C).
  2. Bake Potatoes:
    • Wash the potatoes and pierce them several times with a fork. Place the potatoes on a baking sheet and bake for 45-60 minutes, or until they are tender when pierced with a fork.
  3. Cool and Scoop:
    • Allow the potatoes to cool slightly. Cut them in half lengthwise and scoop out the flesh into a large mixing bowl, leaving a small border in the skins if you plan to use them for another dish. Discard the skins or save them for another use.

Step 2: Prepare the Potato Mixture

  1. Mash Potatoes:
    • Mash the scooped-out potato flesh with a potato masher or an electric mixer until smooth.
  2. Add Ingredients:
    • Add the unsalted butter, sour cream, milk, onion powder, garlic powder, salt, and black pepper to the mashed potatoes. Mix until well combined and creamy.
  3. Stir in Cheese:
    • Stir in ¾ cup of the shredded sharp cheddar cheese, ¾ cup of the shredded Monterey Jack cheese, and half of the crumbled bacon.

Step 3: Assemble the Casserole

  1. Transfer to Baking Dish:
    • Transfer the potato mixture to a greased 9×13-inch baking dish, spreading it out evenly.
  2. Top with Cheese and Bacon:
    • Sprinkle the remaining ¼ cup of sharp cheddar cheese, ¼ cup of Monterey Jack cheese, and the remaining crumbled bacon over the top of the potato mixture.

Step 4: Bake the Casserole

  1. Bake:
    • Bake the casserole in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.

Step 5: Serve

  1. Garnish:
    • Sprinkle the chopped green onions over the top of the casserole.
  2. Serve Hot:
    • Serve the Twice Baked Potato Casserole hot, straight from the oven. Enjoy the creamy, cheesy goodness!
