Decadent Scalloped Onions

How can steak be even better? Cheer for decadent scalloped onions!

I want to get this out there right away: Decadent Scalloped Onions are not good for you. And you’re not going to care. “Side dish” might be a little exuberant – these are almost a condiment they’re so rich. As you might imagine, too many of these might well create some problems {{ahem}} intestinally. You’ve been warned.

My Mom made these on special occasions,

And I do the same thing… they’re perfect with a Birthday Dinner or a Christmas Tenderloin. The whole house smells heavenly when these babies are cooking, and guests often walk in the front door sniffing.

Did I mention Scalloped Onions only have 4 ingredients?

These prove irrefutably that simple is best. We slice the onions thinly and then assemble the dish. I love to use this awesome Mandoline Slicer (affiliate link), but thinly slicing using your best knife skills works perfectly too.
