Onion Slice Gratins

Onion gratinDo most of your favorite recipes start with these words: “Saute onions and garlic in butter?” Yeah, me too!

How to tell if you’re an onion addict (like me): 1) You choose burger joints by how yummy their rings are; 2) You actually  like the lingering smell of onions in your kitchen; 3) You eat green onions raw; 4) You eat caramelized onions just all by themselves, with or without crostini.

And how about this one: onions are not just thrown in – they are the star of the recipe! These pretty little rounds are so easy to make and look so great next to a main dish as a sassy side.

My inspiration came from fabulous low carb blogger Kalyn at Kalyn’s Kitchen. She did and Onion Gratin with Rosemary and Thyme in a 9 by 13 dish that I have made several times, and my family loved this dish. I decided to make individual servings by slicing the onions into 1-inch slices and baking them on a baking sheet. Same great flavor – in individual servings!
