This creamy paleo chicken, broccoli, and rice casserole is packed with flavor and filling in the best way! It’s Whole30 compliant, keto, dairy free and perfect to make ahead of time for easy lunches and dinners.
Here’s are two not-so-scandalous secrets about me. 1.) I used to be anti-casserole and 2.) I used to be anti-cauli rice.
And now he we are, on the first day of 2019 with a DEEE-licious paleo and Whole30 casserole that does in fact use cauliflower rice. Things change, and I’m not afraid to admit that I was oh-so-wrong way back then.
I’m pretty sure all my issues with casseroles AND cauli rice can be summed up with one word: mush. Not the most appetizing word. But in truth, every paleo casserole I tried in the beginning seemed to just turn to mush, in a bad way. (Is there ever good mush, really? I guess not.)
Things have changed, however. A good thick sauce, lots of “goodies” (as I always say), and avoiding the dreaded overcooked cauli rice helps a whole lot.
And you might know by now that by “goodies” I’m talking about bacon, mostly. But honestly the roasted broccoli is a goody in my book as well. When done right it’s completely impossible to stop eating!
This casserole has several steps but it’s overall very easy to throw together. First, you’ll prep and then roast the chicken and broccoli in the oven. Meanwhile, you’ll make the bacon and then the sauce.
The sauce is very simple – onions, garlic, ghee, broth, coconut milk, thickener, salt, pepper, and fresh herbs. I also used nutritional yeast and some spicy brown mustard, which helps mimic the flavor of cheese and adds extra yumminess to the sauce.
The cauli rice is stirred into the sauce at the very last minute to avoid overcooking. Then the cooked, shredded chicken, broccoli, bacon, sauce, and rice are all baked together in a casserole dish. The result is so tasty that you won’t believe you’re actually eating something good for you!
This casserole is perfect to make ahead of time for easy lunches since the leftovers reheat so well. It’s one of those meals that might even taste BETTER leftover since all the flavors have a chance to blend.
It’s great for picky eaters too – the chicken, bacon, and broccoli usually go over well with kids! Plus, the “cheesy” flavor of the sauce has no hint of the coconut milk, so no worries for all you coconut haters. (I’ve learned over the years that coconut seems to be a love it or hate it sort of flavor.)
I hope you’re ready for the best kind of healthy comfort food! Grab all your ingredients and get that oven preheated. It’s time to make the best Paleo Chicken, Broccoli, and “Rice” Casserole – let’s go!

- 1/4 sea salt or to taste
- 1/8 tsp black pepper or to taste

Remaining Ingredients:
- 12 oz cauliflower “rice” - I purchase this already prepped to save time
- 1 lb boneless skinless chicken breasts
- 1 lb broccoli florets
- 3 Tbsp avocado oil or olive oil, divided Sea salt and pepper
- 1/2 lb nitrate free bacon sugar free for Whole30
Instructions
-
Preheat your oven to 425 degrees. Place chicken on a baking sheet and coat with 1 1/2 Tbsp olive oil and sprinkle with salt and pepper.
-
On a separate baking sheet lined with parchment paper, arrange broccoli and toss with 1 1/2 Tbsp avocado oil plus salt and pepper.
-
Roast chicken for 20-25 minutes or until cooked through. Midway through, flip the chicken and for even roasting. Roast broccoli for 15-20 mins or until fork tender, stirring midway through.
-
Once done, lower the oven temp to 400 degrees.
-
While chicken and broccoli roasts, cook bacon until crisp in a large skillet, drain, and make the sauce:
-
For the sauce, heat a medium saucepan over med heat and add the 3 Tbsp cooking fat. Add the onions, cook until translucent and fragrant, then add the garlic and continue to cook until soft, adjusting heat if necessary.
-
Whisk the tapioca flour into the broth and add it to the pan, then immediately add the coconut milk, mustard and nutritional yeast, (if using), while whisking. Raise the heat and bring to a boil, stirring. Once boiling, lower to a simmer and continue to stir and cook for another minute, until nice and thick. Stir in salt and pepper to taste, add the fresh herbs. Stir in the cauliflower rice to soften, then remove from heat.
-
Cut the chicken into bite size pieces, or shred, and arrange in a casserole dish, then add the roasted broccoli and the sauce/rice mixture, stir to evenly coat. Crumble the cooked bacon and sprinkle all over, then bake in the preheated oven for about 20 minutes, until heated through and cauli rice is soft. Serve hot and enjoy!

I made this tonight, with actual rice, and it was soooo comforting and cozy and delicious. Not watery just perfect. Looking forward to leftovers. And will try a cauli rice version some other time. Thank you.
Did you cook your rice ahead of time, or just add it uncooked and let it cook in the sauce?
Can this be frozen??
Do you use 9×13 dish or another size. Sorry if it is in the instructions; I promise I looked before posting. Looking forward to trying it!
Yes 9×13
Is the nutritional info for 1 serving or for the whole dish…500 calories with the contents provided seem a bit steep.
I just tried this and it turned out completely watery 🙁 the sauce went into the casserole dish super creamy so I was pretty disappointed. I’m guessing that if I cooked the cauliflower rice ahead of time and squeezed out all of the moisture, it would’ve held up better.
Super delicious! The whole family liked it. I was looking for a chicken broccoli rice casserole sub. I 1.5x the recipe and put it in a bigger pan and it worked great. I made it keto by subbing tapioca flour for glucomannan(1/2-1tsp).
Super delicious and all my kids loved it!
Hi…do you think I could make all of the “parts”….sauce, chicken, broccoli, bacon and store separately and then add the cauli rice and put together and cook? trying to do some sunday cooking for dinners during the week. Thank you!
Soooo good! My family loved it!!
Didn’t love the sauce, but I think just adding more seasonings will be the difference, it was overall really good!!! I’ll definitely make this again. Only change I added was a no steroid helping of fresh sliced mushrooms before throwing in the oven. Tasty!
I definitely said a “massive” helping of mushrooms, not no steroid! Haha
Great and makes fabulous leftovers. My kids ask for this all the time.
