- 2 cloves Garlic: Freshly minced for that punch of fragrant depth.
- 1 cup Sharp Cheddar Cheese: Melts beautifully to create a creamy, cheesy layer; mozzarella can be used for a milder bite.
- 1 cup Low-Sodium Chicken Broth: Keeps the casserole moist and infuses it with rich flavor; vegetable broth is a good alternative.
- 1 tsp Salt: Enhances all the natural flavors—adjust to taste.

How to Make Delicious Christmas Chicken Cauliflower Rice Casserole Recipe
Step 1: Prepare the Chicken and Veggies
Start by cutting your boneless, skinless chicken breasts into bite-sized pieces so they cook evenly. Heat olive oil in a large skillet over medium heat and sauté the onion until it becomes translucent and sweet. Then add the minced garlic and cook just until fragrant, about 30 seconds. Toss the chicken pieces in and cook until they are no longer pink inside, seasoning with salt, black pepper, and paprika as you go to layer in that festive holiday flavor.
Step 2: Add the Cauliflower Rice and Broth
Once the chicken and aromatics are cooked, stir in the cauliflower rice. Pour in the chicken broth to keep everything moist and flavorful, letting the mixture simmer until the broth reduces slightly and the cauliflower is tender. This step brings the ingredients together beautifully, creating a savory base with lots of delicious aroma filling your kitchen.
Step 3: Layer in the Cheese and Bake
Preheat your oven to 375°F (190°C). Transfer the chicken and cauliflower mixture into a casserole dish and sprinkle the sharp cheddar cheese evenly on top. Bake for about 20 minutes or until the cheese is bubbly and golden brown. This melting layer adds that ooey-gooey comfort factor that makes this dish a true crowd pleaser.
Step 4: Rest and Serve
Once out of the oven, let the casserole rest for 5 minutes. This allows all the flavors to settle and makes serving a breeze. You’ll notice the aroma intensifies, promising a festive meal full of delightful textures and tastes.

Garnishes
Nothing elevates a casserole like fresh garnishes. Try sprinkling chopped fresh parsley or chives on top to add a bright pop of color and fresh flavor. A light dusting of paprika can also enhance the festive look and provide a slight smoky touch making every bite more inviting.
Side Dishes
This casserole pairs beautifully with vibrant side dishes. A crisp green salad with a citrus vinaigrette balances the richness, and roasted Brussels sprouts or glazed carrots add vibrant holiday color and texture. These sides keep the meal fresh yet satisfyingly seasonal.
Creative Ways to Present
Consider serving the casserole in individual ramekins for a charming presentation that feels homemade yet special. Or use a festive casserole dish that complements your holiday table decor. Adding a sprig of rosemary or a few cranberries on the side can also tie the dish perfectly into your Christmas feast.
Make Ahead and Storage
Storing Leftovers
The Delicious Christmas Chicken Cauliflower Rice Casserole Recipe keeps beautifully in the fridge, stored in an airtight container for up to 4 days. This makes it an excellent option for busy holiday weeks when you want a comforting meal ready to go.
Freezing
You can freeze this casserole prior to baking for up to 3 months. Just assemble it in a freezer-safe container, cover tightly, and freeze. When ready to enjoy, let it thaw overnight in the fridge before baking as per the instructions to preserve the flavors and texture.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through and bubbly, usually about 15-20 minutes. Using the oven ensures the top stays crisp and the cheese melts back perfectly. Alternatively, microwave reheating is faster but can make the casserole slightly softer on top.
FAQs
Can I use turkey instead of chicken?
Absolutely! Substituting turkey breast works wonderfully and adds a holiday twist while keeping the dish lean and flavorful. Just be sure to cut it into similar-sized pieces for even cooking.
Is fresh cauliflower rice better than frozen?
Both fresh and frozen cauliflower rice work well. Fresh offers a slightly firmer texture, while frozen is convenient and just as tasty once cooked. Just be sure to drain any excess moisture if using frozen to avoid a soggy casserole.
Can I make this casserole dairy-free?
Yes! Swap the sharp cheddar cheese for a dairy-free cheese alternative or nutritional yeast to maintain the cheesy flavor without dairy. Also, ensure your broth is dairy-free for best results.
How spicy is the casserole?
The recipe uses mild paprika, so it typically has a warm, smoky flavor without much heat. You can add a pinch of cayenne pepper if you like a bit of spice or omit paprika if you prefer it milder.
What can I serve with this casserole for a full holiday meal?
Pair this casserole with fresh vegetable sides like roasted Brussels sprouts, sautéed green beans, or a bright cranberry sauce for a festive, balanced holiday plate.
