Easy Loaded Baked Potato Casserole

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9×13-inch baking dish.

Step 2
Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain and return potatoes to the pot to dry.

Step 3
Meanwhile, arrange bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain bacon on a paper towel-lined plate; crumble and set aside.

Step 4
Combine 1 1/2 cups Cheddar cheese, evaporated milk, 1/2 cup green onions, sour cream, 1/2 of the crumbled bacon, salt, and black pepper in the pot with potatoes. Mash with a potato masher until creamy. Spread mixture into the prepared baking dish.

Step 5
Bake in the preheated oven for 25 minutes. Sprinkle with remaining Cheddar cheese, green onions, and bacon. Return to the oven and continue baking until cheese is melted, about 5 minutes more.
