Mashed Cauliflower Gratin [Recipe]

This is a perfect side dish for your Thanksgiving feast! You can get all of the creamy cheesy goodness of potato gratin with a whole lot less carbs thanks to cauliflower!  Plus the egg whites pack a protein punch, something that can be hard to get enough of during the holidays.

I used a large baking dish to prepare this cauliflower gratin, but I think this would look so great served up in ramekins. It would also make it super easy for tracking!

If you’re really stuck for time, you could even use bags of frozen cauliflower rice. All you do is microwave them first, drain any excess water and then mix the riced cauliflower with the rest of the ingredients in a large bowl. Soooooo simple & so tasty!

Mashed Cauliflower Gratin

Laura Daniel

A take on a potato gratin with a whole lot less fat and carbs thanks to cauliflower and egg whites.  If you're looking to make it your own try out different types of cheese for the topping. I used a light cheddar but gruyere would be a great alternative!
