Sometimes you need a dish that is straight comfort food with no surprises.  This Cozy Chicken and Cauliflower Rice Casserole is just such a dish.  Although plenty creamy, it’s no slouch in the veggie department either.  A savory, low carb casserole that can be made in advance and heated when you need it, this recipe is great even for your picky eaters.

What You Need to Make Cozy Chicken and Cauliflower Rice Casserole

Equipment

  • Cutting Board – For dicing the veggies.
  • Chef’s Knife – For dicing the veggies
  • Measuring Cups – I like this plunger-style one for the mayo, sour cream, and heavy cream. 
  • Measuring Spoons
  • Large Sauté Pan or Skillet
  • Rubber Scraper – Or other stirring utensil
  • 9×13-inch Casserole Dish

Ingredients

  • Carrots
  • Celery
  • Onion
  • Avocado Oil – This is for sautéeing the veggies.  You can use regular olive oil if you prefer.  
  • Kosher Salt – I suggest starting with the recommended amount, but feel free to adjust to taste.
  • Ground Black Pepper – As with salt, I’d say to start with what’s in the recipe but feel free to adjust to taste.  
  • Garlic Powder
  • Dried Oregano
  • Dried Thyme
  • Dried Sage
  • Cauliflower Rice – I use 2 (12-ounce) bags as long as I can find them.  If your store only has 10-ounce or 10.5-ounce bags that’s fine.
  • Sour Cream
  • Mayonnaise
  • Heavy Cream
  • Cooked Chicken Cubes – I use a 22-ounce bag of precooked chicken from the freezer section at the grocery store.  

Getting Started with Making Cozy Chicken and Cauliflower Rice Casserole

I know that the ingredient list may look a little long, but it’s actually pretty straightforward.  

Prepping the Vegetables

We’ll get started by peeling and dicing 3 large carrots, 3 stalks of celery, and 1 large onion.  The quantities of each of those three should be roughly equal.  However, if the balance is a little off, that’s fine.  Set all of the diced vegetables aside.  

Then you’ll want to get the rest of your ingredients together before you start cooking.  

Cooking the Veggies and Putting Everything Together

Next we’ll heat 1 – 2 tablespoons of Avocado Oil in a large sauté pan over medium high heat.  Sauté the onions, celery, and carrots until softened.  About 8 minutes.  Then we’ll stir in 1 teaspoon of Kosher Salt, 1 teaspoon of Ground Black Pepper, 1 teaspoon of Dried Oregano, 1 teaspoon of Dried Sage, and 1 teaspoon of Dried Thyme.  Make sure the seasonings are well integrated.  Then add in 24 ounces of Cauliflower Rice and mix again.  

Once the Cauliflower Rice is cooked through, you’ll add ½ cup of Sour Cream, ½ cup of Mayonnaise, and ¼ cup of Heavy Cream and mix well.  

Finally, you’ll turn off the heat and stir in the chicken cubes.  

Baking the Cozy Chicken and Cauliflower Rice Casserole

If you are preparing this Cozy Chicken and Cauliflower Rice Casserole in advance, you can pause at this point, and store the mixture covered in the fridge until ready to bake.  

To bake the casserole, you’ll want to preheat the oven to 350°F and thoroughly grease a 9×13-inch casserole dish with cooking spray.  Then pour the mixture into the casserole dish and bake at 350° for 20 minutes or until it is heated through and gooey.  If it’s been in the fridge, it will be more like 45-55 minutes.  (Everything is cooked, so you’re just heating everything through and allowing the creaminess to permeate the entire casserole.)  

If you’d like, you could sprinkle some cheese of your choice on top before baking it.  Serve warm.
