Can These Be Frozen
It is not recommended to freeze these. Potatoes change in consistency that is not desirable to most people. That said, it doesn’t spoil them to freeze it. If you don’t mind that, go for it.
How to Store Leftover Make Ahead Mashed Potato Casserole
If you have leftovers, store in an airtight container in the refrigerator for up to 5 days.
The Bacon
Cook the bacon however you prefer. I like to cook it in the microwave. See How To Cook Bacon in the Microwave.
I almost always use freshly cooked bacon but have sometimes used precooked bacon from a bag. It worked just fine too. Hormel Real Crumbled Bacon is a great choice. Use about 1 cup.

Notes
If baking right after assembling, it won’t be chilled through so only bake 20 minutes covered plus 10 minutes uncovered.
This can easily be halved to serve 10 people. Put it in a 7x11 dish and bake 20 minutes covered plus 10 minutes uncovered.
