I’m a Midwestern girl through and through.

What does this mean?

Well, it means that I put ranch dressing on ev.ery.thing. Like, EVERYTHING.

It also means that, back before I was all low carb, I ate a whole heck of a lot of corn on the cob.

And, most importantly, it means that casseroles are my life.

I’m sorry, but there is just something comforting and homey about a 9×13 dish full of cheesy goodness.

This low carb chicken casserole surprised me. I knew I was going to like it when I was throwing it together the first time, but I was surprised by just how perfect it was.

A low carb casserole that makes the whole family happy? Yes, please.

How to:

You can use fresh cauliflower and rice it yourself for this recipe or you can use a bag of frozen cauliflower rice. Either will work fine!

We’re going to start by cooking the cauliflower rice. Follow the directions on the bag or steam your fresh cauliflower.

Cooking the rice first means we’ll avoid the casserole getting too much liquid from the veggies.

While the cauliflower is cooking, you’ll also want to steam some broccoli and fry some bacon.

Add the steamed cauliflower rice and broccoli to a mixing bowl along with some cooked, shredded chicken, crumbled bacon, eggs, cheddar, and your seasonings.

Mix it all up and toss it in a 9×13 baking dish.

What comes out of your oven is pure comfort food!

  1. A friend had posted this on our keto group and I had a rotisserie chicken from the weekend – and it was amazing, not dry at all, I added mushrooms, leeks and spinach along with the cauliflower rice (frozen and steamed) and broccoli florets (fresh, steamed). I also added ranch seasoning because it seemed like a good fit! VERY yummy, keto friendly and I am pretty sure my family will love it too. Thank you!!

      So glad you enjoyed it, Denise! Sounds like you made some tasty additions. πŸ™‚

  2. This was outstanding! I like the Tropicland riced cauliflower from Costco, but I find it tastes best and maintains a β€˜rice’ consistency when I use it frozen. I used frozen broccoli cuts also, so I baked it for an hour. Not too much moisture. I was amazed at how delicious it was without any cream soup or sour cream. This is a Keto keeper! Thank you.

      So glad you enjoy the recipe! And happy to hear it worked well with frozen veggies.

  3. Delicious! I used fresh broccoli and fresh cauliflower. I just cut up both into florets because I was too lazy to rice the cauliflower. Still came out great. Glad I came across this recipe!
