Creamy Mushroom Potato Au Gratin

What a yummy dish this was!  It is basically your regular Au Gratin, with two special ingredients!  This Mushroom Potato Au Gratin has the regular suspects: potatoes, heavy cream, parmesan, and the special ingredients of mushrooms and smoked bacon & onion sea salt!  Those two changed the entire game on this one!

This here was the extra super secret ingredient…  and it comes from an Olive Oil Company in Blue Ridge, aptly called the Blue Ridge Olive Oil Company.  I don’t see it for sale in their online store, so you might just have to make your way to Noth Georgia to visit and get your own!

Smoked Bacon and Onion Sea Salt

It is pretty simple to make and kicks up your regular Au Gratin several notches.

If you don’t have this special salt, I found one here:  but I can’t vouch for it – it looks the same as mine, but you never know!  It really changes the game for this dish though, so maybe give it a try???
