Lately, Maddie and I have been in a keto side dish rut.  I’ve been finding myself skipping the side dishes all together and just topping my protein with a couple slices of avocado or a spoonful of guacamole.  Honestly, the lack of a side dish really doesn’t bother us, but I know with the holidays quickly approaching that I need an easy keto side dish we can get excited about and delicious enough to serve to our guests! And this Keto Zucchini Gratin is over the top amazing!

As far as keto side dishes, anything “au gratin” is at the top of my list.  Au gratin potatoes were always a favorite as a kid, so I decided to gratin one of our favorite keto veggies…zucchini!  That caramelized, crispy brown top is everything!! This keto zucchini recipe is spiced up with cumin and uses poblanos for a little Texas flare, so easy and incredibly delish!

Perfect for entertaining, this one skillet wonder is done in less than 30 minutes!

This Keto Zucchini Gratin is made in a skillet, then put into the oven to finish cooking and to create that tasty brown crust that everyone goes crazy for!  A cast iron skillet is great to use here but if you don’t have one, make sure to use an a skillet that’s oven safe up to 400 degrees.

The process for this keto zucchini recipe is so simple, which makes it perfect for the holidays!  First, the onion and poblanos get sautéed in some butter until tender.  Then the garlic and cumin are added and cooked for another minute.  The sliced zucchini then goes into the pan and sautéed with the onion and poblanos until just tender.  In goes the cream, cheese and sour cream, and everything gets gently tossed together, topped with cheese and into the oven!

I like to use Monterey Jack cheese, or if you like spice, use Pepper Jack for a little additional heat!

How to Serve This Keto Zucchini Gratin

I like to serve this keto side dish right out of the skillet topped with a little Mexican Crème, chopped parsley, and crumbled Queso Fresco or Cotija cheese for a little extra oomph, but its amazing just as it comes out of the oven!
