Creamy Pour-Over Baked Potato Casserole

by
This Creamy Pour-Over Baked Potato Casserole takes all the best flavors of a fully loaded baked potato—crispy bacon, sharp cheddar, rich sour cream, and tender potatoes—and turns them into an ultimate comfort food casserole.

The secret “pour-over” method involves a savory, seasoned cream mixture poured evenly over the layers, ensuring every single bite is ultra-moist, creamy, and packed with flavor.

Prep and Cook Times

  • Prep time: 20 minutes
  • Cook time: 50–60 minutes
  • Yield: 8 to 10 servings (1 standard 9×13-inch baking dish)

Ingredients

The Potatoes & Toppings:

  • 3 lbs russet or Yukon Gold potatoes, peeled and cut into 1/2-inch cubes (about 6 to 7 medium potatoes)
  • 6 slices thick-cut bacon, cooked until crispy and crumbled
  • 2 cups freshly shredded sharp cheddar cheese (divided)
  • 1/3 cup green onions or chives, finely chopped

The Creamy Pour-Over Mixture:

  • 1 cup sour cream
  • 1 can (10.5 oz) condensed cream of chicken soup (or cream of mushroom/celery)
  • 1/2 cup whole milk or heavy cream
  • 1/4 cup unsalted butter, melted
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon salt (plus more for boiling)
  • 1/4 teaspoon black pepper

Step-by-Step Instructions

1. Boil the Potatoes

  1. Place the cubed potatoes into a large pot and cover them with salted water. Bring to a boil over medium-high heat.
  2. Cook for about 8 to 10 minutes, just until the potatoes are fork-tender but still firm enough to hold their shape (you don’t want them mushy, as they will cook more in the oven).
  3. Drain the potatoes thoroughly and set aside.

2. Mix the Creamy Pour-Over Sauce

  1. In a large mixing bowl, whisk together the sour cream, condensed cream soup, milk (or heavy cream), melted butter, garlic powder, onion powder, salt, and black pepper until completely smooth and well combined.

3. Assemble the Casserole

  1. Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Add half of the drained potatoes to the bottom of the prepared dish.
  3. Sprinkle with half of the crumbled bacon, half of the green onions, and 1 cup of the shredded cheddar cheese.
  4. Add the remaining potatoes on top.
  5. The Pour-Over: Pour the creamy sour-cream mixture evenly all over the top of the casserole, using a spatula to spread it gently so it seeps down between the layers.

4. Bake and Melt

  1. Cover the baking dish tightly with aluminum foil and bake at 375°F for 30 minutes to let the creamy sauce bubble and infuse the potatoes.
  2. Remove the foil, sprinkle the remaining 1 cup of shredded cheddar cheese and a little extra bacon on top, and bake uncovered for another 15 to 20 minutes, until the cheese is melted, bubbly, and lightly golden.

5. Rest and Serve

  1. Let the casserole rest for 10 to 15 minutes before slicing and serving. This allows the creamy sauce to set up so it’s easy to scoop!
  2. Garnish with the remaining fresh chives or green onions.
Pro-Tip: You can assemble this entire casserole a day ahead of time, cover it, and keep it in the refrigerator. Just add an extra 10 to 15 minutes to the covered baking time if baking straight from the fridge!
