Healthy Broccoli ‘Rice’ Casserole

HEALTHY BROCCOLI RICE CASSEROLE is made with cauliflower rice for a grain-free casserole that is low carb and keto-friendly. This low carb broccoli rice casserole is a hit with my kids and it’s really easy to throw together for a quick side dish any night of the week.

I hear from so many of you that you get bored eating the same foods over and over again. 

I get it. I’m a total foodie so if I don’t have a whole lotta variety, I quickly get tired of the same ol’ thing. Well, unless that same ol’ thing is pork tenderloin topped with garlic butter. I could probably eat that every day. 😉 

My biggest trick to keeping dinner time exciting is to get creative with the side dishes. Change them up!! You don’t need to eat the same steamed broccoli and side salad every night of the week. 

This broccoli rice casserole is a perfect example. My kids have always loved the traditional version made with real rice, so why not test out a cauliflower rice version on them? THEY LOVE IT! 

I love that it’s low carb so the whole family can eat it and it’s made with extra veggies so I feel good about it.

How cauliflower rice is made: 

Cauliflower rice is just finely chopped cauliflower! 

You can make it at home with a sharp knife and a little patience, or you can use a food processor.

I use this food processor (affiliate link) and really love it for making cauliflower rice, grating cheese, or slicing turnips for my turnips au gratin. It’s a workhorse and gets a lot of use in my kitchen.

Most grocery stores also sell riced cauliflower and it’s totally fine to use either fresh (found in the produce section and called ‘cauliflower crumbles’ at Walmart!) or frozen. 

Check out my cilantro lime cauliflower rice or cauliflower chicken fried rice too!

Low carb broccoli rice casserole: 

Add your (fresh or frozen) cauliflower rice to a large mixing bowl along with some chopped broccoli florets and a tablespoon of water. Cover the bowl with plastic wrap and microwave for 3 minutes. Let sit for 2 minutes and then carefully remove the plastic wrap.

Add in your cheddar, cream cheese, eggs, and spices and give it all a big stir. 

Spread your broccoli rice casserole into a 9×9 baking dish and top it all off with a little more cheddar.

If you’d like a crunchy coating on top, add some crushed pork rinds!

Bake this up for about 30 minutes and then dig in! 

This healthy broccoli rice casserole is so easy, so cheesy, and a total winner in my book!

What to serve with this keto broccoli cauliflower rice casserole: 

This side dish goes well with most proteins!

Garlic butter shrimp is a hit with everyone that tries it. My stuffed chicken breast, breaded pork chops, and grilled ranch chicken are delicious too!

These steak bites would also be a great option and so would this bacon wrapped meatloaf!

More low carb side dishes to try: 

My keto Brussels sprouts are roasted with a little Balsamic vinegar and they’re seriously so good, even for this non-sprout lover. 😉 

I share all my tips for the perfect mashed cauliflower here! Also, grab our family’s favorite broccoli cheese casserole

Cheesy asparagus, keto coleslaw, and cucumber tomato feta salad are all super quick to whip up and big hits with my kids.

      The recipe serves 6, so 1/6th of the full recipe. We didn’t measure by volume or weight.

    1. Karly Campbell

      Healthy is a subjective term and, in terms of keto and low carb, this fits the bill. 🙂

  1. This was amazing! Had to Substitute & use half and half but it was DELICIOUS. Definitely will incorporate in my keto lifestyle.

  2. Emily Cortez

    This was just about my favorite side dish I have ever made!!! I used all frozen veggies my fresh broccoli went bad unfortunately. I made it exactly as the recipe says except for the cheese on top I forgot about and I didn’t even miss it. I will be making this a lot!!! Thank you for a great recipe. I can’t even begin to understand the people who didn’t like it. It’s cheese, cream cheese, and veggies what’s not to love about that!!!

    1. Karly Campbell

      So glad to hear you love it and that it’s still good with all frozen veggies! 🙂

  3. This has become one of my favorite veggie side dishes. My husband loves it too. Thank you for sharing!

  4. How about using frozen cauliflower rice and frozen broccoli in this recipe? Would I have to do anything different?

    1. Karly Campbell

      You just want to make sure the vegetables are lightly steamed in step 3. You may need to adjust the microwave time.

    2. I use frozen riced cauliflower and just microwave it in the bag for 3 minutes before putting it in the bowl with the broccoli and then microwaving them together for 5 minutes. HTH.

  5. I added cubed ham that I had leftover from our Easter Dinner and it turned out amazing! My family loved it! I will be making it again!

  6. Excellent dish – I added 2 pieces of crumbled cooked bacon to the dish. Definitely will make again but will probably add about a 1TBS of half and half for just a little more creaminess. TFS

  7. HOLY WOW! This was so good I am drooling just thinking about it! I’ve made it twice now and it’s now on our weekly menu. The first time I made it I followed the recipe and it was great. The second time I didn’t have any cream cheese so I included some pepper jack cheese in with the cheddar and it turned out great! Even my husband who is spice adverse enjoyed it. We don’t enjoy pork so no crunchy topping but I don’t feel like we missed out on anything. Also, the dried mustard takes it over the top! Don’t leave it out. Thank you so much for a recipe that we’ll be using for years to come.

    1. Karly Campbell

      Hi Ann! I’m so glad this was such a success for you! I bet it was great with the pepperjack! 🙂

  8. Porsha Plyler

    Could you add chicken to make this a chicken, broccoli and cauliflower rice cassarole

  9. Hi, how did you calculate the overall nutritional information like for fat, cholesterol, etc? Just because I am doing WW and am going to sustitute with fat free cheddar and low fat cream cheese and would like how to calculate nutritional facts!

    1. Karly Campbell

      Hi Cassandra! My recipe card that I use calculated it automatically. You could try plugging this into My Fitness Pal and changing things around to suit your needs though.

  10. Helene Measor

    We love this. I will definitely drain the cauliflower and broccoli next time. Bottom came out a bit watery.

    1. Karly Campbell

      Oh, I should have mentioned to do that. I’m sorry. It’s updated in the recipe now. 🙂

  11. Tried this Healthy Broccoli ‘Rice’ Casserole for Christmas Dinner. Big disappointment. Followed recipe exactly with quality ingredients. Had an “off” taste, very strong. Disgusting! Don’t try this one!

    1. Karly Campbell

      Hi Debbie! Not sure what would cause an ‘off’ taste unless one of your ingredients were bad. Or perhaps you just don’t like cauliflower?

    1. Karly Campbell

      Hi Julie! You could probably just leave it out. It does add some creaminess and thickens the mixture up, but I think it’ll be okay without it.

      1. Tara Jones

        I’ve got this in the oven now to go with my sugar free bbq boneless ribs. I made it exactly as written except instead of mustard powder I used a couple squirts of Dijon mustard. I am betting it will be a yummy dish. Thank you!

    1. I’m excited to try this! I don’t have mustard powder though….will it be ok without it or should I wait until I can get some?

      1. Karly Campbell

        You can skip it. It does add a little pop to the cheese, but I think it’ll be fine without.

    1. Karly Campbell

      Hi Wendy! This would probably be fine made the day ahead, but I always think broccoli and caulifower are best fresh. If you don’t mind them reheated, go ahead and make in advance. 🙂

        1. Karly Campbell

          Hi Kelly! I didn’t measure by volume. I just divided into 6 equal servings.
