Step 1

Preheat the oven to 325°F (165°C) and grease a 9x13 inch baking dish.

Step 2

In a large bowl, mix the diced potatoes, grated cheddar cheese, crumbled bacon, sliced green onions, and garlic salt until evenly combined.

Step 3

Add the mayonnaise and stir until all the ingredients are well coated. Then, pour the potato mixture into the prepared baking dish and spread it into an even layer.

Step 4

Bake for about 1 1/2 hours, or until the potatoes are tender when pierced with a fork and the top is golden brown.

Step 5

Remove from the oven and let cool for 5-10 minutes before serving warm. Garnish with additional sliced green onions and bacon if desired. Enjoy!
