I’m so excited that Taryn invited me to Guest Post on Joy Filled Eats! I am thrilled to share this simple and scrumptious Green Chile Cauliflower Rice Casserole, inspired by one of my all-time favorite family dishes!

Keto Cauliflower Casserole = Comfort food
One of my favorite things to do is to take my favorite childhood comfort food recipes and “de-carb” them! We all have those dishes that evoke “food memories” …sometimes for me, it’s just the aroma that does it! Well, just because we are living a low-carb or keto lifestyle shouldn’t mean that we miss out on all those amazing flavors from our past!
Green Chile Cauliflower Casserole was inspired by one of my favorite special occasion dishes. I remember it was always on the table at Christmas and other holiday dinners…or at least I hoped it was! It’s funny…I’m not quite sure why it was reserved mostly for special occasions because it is so easy to make…probably because it is rich and decadent and those dishes in our house were always reserved for holidays! The version from my childhood had white rice as the main ingredient so I switched it up with some cauliflower rice, made a few other modifications and I have to say this low carb version is even better than the original…sorry, mom!

Cauliflower rice in cauliflower casserole?
As you now know, I live on a ranch out in the middle of Texas with my husband, the Cowboy, and my two girls. We are about 45 minutes away from the nearest store, so we stock up on groceries when we go to town! While I love fresh veggies, they don’t seem to stay fresh for too long, so to save time and money, I stock up on certain frozen veggies and cauliflower rice is one that we always have on hand! I try to load up when it goes on sale, so we always have it around for a quick side option or to use in our favorite recipes. My daughter Maddie and I are the low carbers around here and we love the versatility of cauliflower rice and use it all the time, for anything from pizzas to casseroles, like this amazing Green Chile Cauliflower Casserole!
One of my other favorite sides is GG’s Oil & Vinegar Coleslaw. And if you are looking for something to serve this with how about Chicken Verde Taco Bowls?

Cauliflower Side Dishes
Cauliflower rice baked in a cheesy, sour cream and green chili sauce and topped with more ooey, gooey melty cheese…sound delicious? IT IS! It’s all my favorite things …creamy, cheesy, decadent, comforting and so incredibly delicious. Served up aside a grilled steak, crispy chicken thighs or even your favorite pork chops, this Keto Cauliflower Casserole will quickly become a favorite side in your weekly meal rotation. It takes minutes to put together and can be made ahead of time, so it can easily be used for meal prep as well! It’s Texas comfort food at it’s finest!

Green Chile Cauliflower Casserole
Ingredients
- 2 tbsp butter
- 3/4 cup chopped onion
- 3/4 cup chopped celery
- 2 cups cauliflower rice
- 1 cup shredded Monterrey Jack cheese
- 1 cup shredded sharp cheddar
- 4 oz canned green chiles drained
- 1/2 cup sour cream full fat
- 1/2 cup heavy cream
- 1 1/2 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp granulated garlic
Instructions
- Preheat oven to 325 degrees. Butter or grease an 8×8 pan and set aside.
- If using frozen cauliflower rice, cook to package directions, usually about 3 minutes. If using fresh cauliflower rice, steam for 3-4 minutes on the stove-top or in the microwave until slightly tender. Take the steamed cauliflower rice and squeeze or press between paper towels to remove the excess moisture and set aside. You want the rice to be fairly dry so your dish isn’t watery!
- Melt butter in a medium sauté pan over medium high heat. Add celery and onions. Cook for 5-7 minutes or until tender. Turn down heat to medium and add cream to the pan and stir constantly and reduce by half, until thick and creamy and set aside.
- In a large bowl combine cauliflower rice, ½ cup of each cheese, chiles, sour cream, veggie mixture and seasonings and stir till incorporated. Spread mixture evenly in the prepared pan and top with remaining cheese. Bake at 325 for 20-25 minutes or until bubbly…Enjoy!

Fantastic! I used cabbage instead of celery and it turned out great. Yummy!!
This is delicious! I will make this again and again! I didn’t put in the celery (didn’t have any) and I accidentally bought “hot” green chilies and it was awesome if you like spicy.
Love love LOVE this recipe! It came out incredible just so tasty!!
This was very tasty. I happened to have fresh green chilies in my garden and sliced them up and cooked them with the onion and celery. Also had a couple of pieces of cooked bacon which I chopped up alll over the top. Wow! My mouth is still glowing. This recipe is a keeper!
Thanks for posting it for all to enjoy!
This was amazing! I could have eaten the entire pan! I steamed 4 cups of cauliflower and kept the rest of the recipe the same. Will definitely make this again!
I’m not a big fan of celery. How necessary is it to the overall flavor of the dish?
It’s not. You can omit it.
This was fantastic! I threw in some diced pickled cactus because I bought it and don’t know what to do with it… ha. Recipe is a keeper!
We really enjoyed this recipe. I made the cauliflower rice from fresh and sautéed it in a skillet with garlic and onion in 2 Tbs of olive oil for 7 min. and added rotisserie chicken to your recipe. My husband went back for seconds. Thanks for sharing!
I turn to this recipe often. I am not a huge fan of cauliflower but I love this dish. Sometimes I add some shredded chicken. Thank you for sharing this tasty dish.
Just how spicy is this dish? I am a wimp when it comes to spicy flavors using peppers. Is the canned green chiles mild?
They come in mild or medium. Mild are pretty mild. Maybe 1 or 2 on a scale of 1-10.
Thank you very much.
Delicious, my family loved it, thank you for another great recipe!
This recipe is delicious! I’ve tried many recipes using cauliflower rice and left with bland results. This one is s full of flavor. The next time I make it I will reduce the amount of cheese to lower total calories. Thanks for the recipe!
Hello. This sounds amazing! Haven’t made it yet but want to. I have family who don’t care for celery. Any suggestions for substituting the celery?
You can just omit it.
Made this a while ago and loved it. Since then, I have made it with leftover chicken or pork added and liked it a lot. Just made again true to recipe, no additions and I have to say I love it even more, as is, no additions. Thanks for such a great recipe.
This dish was absolutely delightful we added chicken to ours😍
