Squash Cauliflower Rice Casserole is a low-carb and gluten-free recipe made with fresh yellow squash, onions, riced cauliflower, cheese and ground pork rinds.   This satisfying comfort food dish can easily fit into a healthy eating plan.

The original recipe that inspired this low-carb makeover came from the “Cooking Light Comfort Food” section of a local Georgia paper in 2011.  We absolutely loved it.  I wanted to reduce the carbs a bit since the original version was made with rice, so I swapped cauliflower rice for the white rice and ground pork rinds in place of the wheat bread crumbs.  It came out just as delicious, if not better than the original recipe.

Low carb casseroles, like this Squash Cauliflower Rice Casserole, are my jam.  Definitely try this Gluten-Free Chicken Butternut Squash Casserole if you haven’t already.  We also love healthier “pasta” dishes like this lean & delicious Spaghetti Squash Meatball Casserole.  So good!

Tips For Making Squash Cauliflower Rice Casserole

To shorten prep time when making this dish,  assemble the casserole the day before you want to cook it.  Cover and refrigerate until you are ready to bake it.  You can even bake it the day before you want to serve it and heat it back up in the oven before serving.

Honestly, Flynn and I both agreed that this Squash Cauliflower Rice Casserole is definitely better the second day.  The flavors had plenty of time to mingle and the texture seemed even creamier reheated a second time around.  It’s now a new staple recipe in this house.  I served it with a rotisserie chicken for a fast and delicious meal.  Gotta love easy!

If you’re on a keto diet, you can use full-fat versions of the cheese and sour cream to increase the fat content.  It’s really important to drain the squash thoroughly after cooking to avoid excess water in the dish.  I add the cauliflower rice to the casserole raw to give it more texture.  It will absorb the extra moisture from the squash and cook in the oven as it bakes.  You can find raw riced cauliflower in a lot of grocery stores, but it’s super easy to make your own in a food processor.  Make sure that you pulse it enough to end up with small pieces, close to the size and texture of rice.

I also used pork panko (aka ground pork rinds) in this dish instead of regular bread crumbs.  They are delicious and zero carbs, but you can easily substitute regular or gluten-free bread crumbs in this recipe.
