Caramelized Onion Mashed Potatoes

I can’t believe it’s Wednesday already! Which means, WIWW!

WIWW with Fitness Meets Frosting

Favorite thing that I wore this past week: A guy I like. I guess it’s more like he’s wearing me around his neck, but whatevs. It only counts cause I also happen to really love that sweater.

And now on to WIAW!

Since all I’ve shown you this past week was food, I thought I’d give you a recipe instead.

I’ve had several blog friends and non-blog friends ask for the recipe I used to make Caramelized Onion Mashed Potatoes on Thanksgiving.

These were a huge hit and I thought it was a nice change from your plain old potatoes. I find that even garlic mashed potatoes can lack flavor. I thought these caramelized onion potatoes had plenty of flavor and didn’t require gravy- but then again, I never use gravy so I’ll shut my mouth.

I found this recipe online, so I cannot take credit. As always, I’ll post my version with changes.
