In your prepared baking dish, combine your diced potatoes, freshly shredded cheddar, crumbled bacon pieces, minced garlic, and chopped onion.

Spoon the mayonnaise over your potato mixture, then gently stir everything together until all ingredients are evenly coated.

Pop your dish into the preheated oven and let it bake for about 1½ hours, until you can easily pierce the potatoes and the top has turned a beautiful golden brown.
