Add the salt, 1/2 teaspoon of garlic powder, and onion powder, and mix everything together. Add the milk to thin the sauce a bit.

Add the tablespoon of mayonnaise and refrigerate while you continue with the other steps.

When it's halfway done, place it on a plate with a piece of paper to absorb the grease. Fry the potatoes.

Cut the bacon if bought in strips, or into small cubes. Heat a pan without oil since the bacon will release some fat, and fry it without fully cooking it because everything will finish cooking later.

Put it in the oven until the cheese is melted to your liking and serve.

Place the potatoes in an oven-safe dish, sprinkle with salt, spread the sauce over the potatoes and bacon. Sprinkle the cheese evenly over the potatoes.
