Green Chili Cauliflower Casserole out of the oven!

Green Chile Cauliflower casserole was inspired by one of my childhood favorite special occasion dishes.  It was always on the table at Easter, Christmas and other holiday dinners…or at least I always hoped it was!  It was always reserved for special occasions in our house because these rich and decadent dishes just weren’t considered every day food!

Lucky for you, living a low carb or keto lifestyle, this cream, dreamy, cauliflower casserole can now a weeknight regular!

Green Chili Cauliflower Casserole made with Cauliflower Rice - Low Car, Keto, Gluten Free

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 we were blown away! I have to say this low carb and keto version is even better than the original…sorry mom! 

As you now know, I live on a ranch out in the middle of Texas and we’re 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 long enough, 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 options or to use in our favorite recipes.  You can also now find it in bulk in the frozen section which is so handy!

Calories: 255kcal


  • 3 T butter
  • ¾ cup diced celery
  • ¾ cup diced white onion
  • ½ cup heavy cream
  • 3 cups frozen cauliflower rice thawed and squeezed dry
  • 1 cup shredded pepper jack or monterrey jack cheese
  • 1 cup shredded sharp cheddar
  • 1 4 oz can mild chopped green chiles drained
  • ½ cup sour cream full fat
  • 1 ½ tsp salt
  • ½ tsp black pepper
  • ½ tsp granulated garlic
  • 1/2 tsp cumin


  • Preheat oven to 325 degrees. Butter or grease a 9×9 pan or medium casserole dish and set aside.
  • Melt butter in a medium sauté pan over medium high heat. Add celery and onions and season with 1 tsp salt. Cook for 5-7 minutes or until veggies are 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 dried cauliflower rice, ½ cup of each cheese, drained chiles, sour cream, veggie/cream 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!


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 stovetop 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!

    This was heaven in a casserole. My stepdaughter couldn’t even tell there was cauliflower rice in it. Added some diced up chicken and voila!
