Notes

Expert Tips:
When boiling the potatoes, cook just until you can easily slide a fork into the potatoes. Even if they are still are a bit firm, it’s ok because they will cook more in the oven. 
After frying the bacon, leave some of that bacon grease in the pan and sauté the onions in it. The onions soak up all that delicious bacon flavor and enhances the whole dish.
Shred the cheese yourself! This is a must for the best flavor and I promise you'll be a whole lot happier with the results. Even if you're cursing me the whole time you're shredding, that's okay. You'll see the pay-off and thank me for it in the end.
Slice the potatoes razor-thin like scalloped potatoes. Or if you prefer a diced potato casserole, roughly chop or dice them. It all depends on how you like to serve them. There's no wrong way of making potato casserole.
