Chicken Cauliflower Rice Casserole

This is my go-to chicken cauliflower rice casserole recipe, and it never lets me down.

Swapping rice for riced cauliflower in a classic casserole genuinely works better than I expected, the texture holds up well once baked, and it soaks up the cheese sauce just as beautifully as regular rice. This has become my regular low-carb comfort food dinner, satisfying in exactly the way a casserole should be.

The key is draining the cauliflower rice well before baking, it releases a surprising amount of water otherwise.

Why This Works

Sautéing the riced cauliflower briefly and draining off excess liquid before combining it with the other ingredients is what keeps the finished casserole from turning watery. Cauliflower holds a surprising amount of moisture, and skipping this step means that liquid releases during baking, diluting the sauce and leaving you with a soupy dish.

Step-by-Step

Sauté the riced cauliflower in a dry skillet over medium-high heat for 5 to 6 minutes, until much of its moisture has cooked off. Transfer to a clean towel and press to remove any remaining excess liquid.

Melt butter in a saucepan and whisk in cream cheese, sour cream, and a splash of chicken broth until smooth. Stir in shredded cheddar until melted.

Combine the drained cauliflower rice, diced cooked chicken, and cheese sauce in a large bowl, mixing until well coated. Spread into a greased baking dish and top with extra cheese.

 

Bake at 375 degrees for 20 to 25 minutes, until bubbling and golden. Let it rest for a few minutes before serving, garnished with fresh chives.
