Preparation:
Start by preheating your oven to a cozy 325°F. This gentle temperature allows the potatoes to cook through without burning the cheese.
Grab a 9×13-inch baking dish and mix together the diced potatoes, grated cheddar cheese, crispy bacon, and sliced green onions. The blend of textures and flavors at this stage is already promising.
Sprinkle in the garlic salt for that hint of garlicky flavor, adding depth to the dish.
Add the mayonnaise and stir everything until well combined. The mayo acts as a binding agent, ensuring each potato piece is evenly coated, promising a moist and flavorful bite every time.
Slide your dish into the oven and bake until the potatoes are tender, and the top is a beautiful golden brown, which should take about 1 hour and 30 minutes.
