Say goodbye to boring potatoes au gratin

We took a basic au gratin recipe and jazzed it up with creamy horseradish cheese and lots of crispy bacon. Say goodbye to boring potatoes.

Creamy horseradish and bacon au gratin potatoes

I have a confession. I’m a huge carb lover and would probably go insane if I were told I couldn’t eat them anymore. Seriously, though, is there anything more comforting than potatoes, cheese and bacon? My husband and I ate these luscious potatoes with a roast chicken, but they are fantastic on their own too. Trust me, I won’t judge anyone who decides these flavor-packed potatoes should be eaten with a fork right out of the pan. I have been known to do this a time or two.
