Twice Baked Potato Dump Casserole takes all the creamy, cheesy, and savory goodness of a twice baked potato and transforms it into an easy, family-friendly casserole. Instead of scooping and refilling individual potato skins, you “dump” all the classic ingredients — fluffy potatoes, sour cream, cheese, bacon, and green onions — into one dish and bake until golden and bubbly. It’s a perfect comfort food for holidays, Sunday dinners, or any night you want something warm and indulgent.

Ingredients
Base:
- 6 large russet potatoes (about 3 lbs) — baked until tender, peeled, and roughly mashed
- 1 cup sour cream
- ½ cup milk (warm, for smoother potatoes)
- 4 tbsp unsalted butter — melted
- 1½ cups shredded cheddar cheese (divided)
- ½ cup cooked bacon — crumbled (plus extra for topping)
- ¼ cup green onions — sliced (plus extra for garnish)
- Salt and freshly ground black pepper — to taste
Optional Add-ins:
- ½ tsp garlic powder or roasted garlic paste
- ½ tsp smoked paprika for a smoky flavor
- ½ cup shredded mozzarella or pepper jack cheese for variety
Directions
- Bake Potatoes: Preheat oven to 400°F (200°C). Pierce potatoes with a fork and bake for 50–60 minutes, or until tender.
- Prepare Casserole Mixture: Peel potatoes and roughly mash them in a large mixing bowl. Add sour cream, warm milk, butter, 1 cup cheddar cheese, bacon, green onions, salt, and pepper. Stir until combined (a few chunks are fine for texture).
- Transfer to Dish: Spread the mixture evenly into a greased 9×13-inch baking dish.
- Top & Bake: Sprinkle remaining cheese and extra bacon over the top. Reduce oven to 350°F (175°C) and bake for 25–30 minutes, until cheese is melted and casserole is hot.
- Garnish & Serve: Sprinkle with extra green onions before serving.
Step-by-Step Preparation Method:
- Bake Potatoes: This is the longest step — baking them whole intensifies the flavor.
- Cool & Peel: Let them cool slightly so they’re easier to handle.
- Mash & Mix: Add sour cream, milk, butter, cheese, bacon, and seasonings.
- Dump into Dish: Spread evenly — no fancy shaping required.
- Top with More Cheese & Bacon: The “twice baked” part comes from adding toppings and baking again.
- Bake Until Golden & Bubbly: Ensures flavors meld and cheese gets melty.
How to Serve
