How to Make BBQ Chicken Cauliflower Rice Casserole Recipe
Step 1: Prep Your Baking Dish
First things first—set your oven to 375°F (190°C) so it’s piping hot when you’re ready to bake. Lightly spray a 9×13-inch casserole dish with olive oil. This keeps everything from sticking and makes serving super simple.
Step 2: Coat the Chicken
In a large bowl, toss the shredded chicken with your favorite barbecue sauce. Be generous—coating every shred ensures that smoky, tangy flavor in every forkful. It’s the feature flavor in this BBQ Chicken Cauliflower Rice Casserole Recipe.
Step 3: Build the Creamy Base
In a separate big bowl, stir together your cauliflower rice, Greek yogurt, garlic powder, salt, and pepper. This combo makes for a savory, tender base that plays so well with the bold BBQ chicken. Fold in the diced red onion and half of the shredded cheddar cheese for even more depth and melty goodness.
Step 4: Combine Chicken and Cauliflower Mixture
Now, fold the saucy BBQ chicken into the cauliflower rice mixture. Give it a good stir until everything is evenly combined for a well-balanced bite of chicken, veggies, and creamy cheese in each spoonful.
Step 5: Layer and Top with Cheese
Evenly spread your combined mixture into the prepared casserole dish. Sprinkle the remaining cheddar cheese all over the top—this is what gives your BBQ Chicken Cauliflower Rice Casserole Recipe its irresistible golden, bubbly finish.
Step 6: Bake Until Bubbling
Slide the dish into the preheated oven and bake for 25 to 30 minutes. You’re looking for beautifully melted cheese and bubbling edges—those are the signs of casserole perfection.
Step 7: Rest and Garnish
Remove from the oven and let it sit for about 5 minutes. This helps the casserole set, making it easier to slice and serve. Just before serving, drizzle a little extra barbecue sauce and shower with plenty of chopped green onions for the freshest finish!

Garnishes
Don’t underestimate the power of a finishing touch! A sprinkle of extra chopped green onion delivers a crisp, fresh bite, while a final drizzle of barbecue sauce amps up that smoky-sweet flavor. For a spicy kick, a few diced jalapeños or a pinch of smoked paprika on top are fantastic options, especially when you want to elevate your BBQ Chicken Cauliflower Rice Casserole Recipe for guests.
Side Dishes
This casserole shines on its own, but you can round out your meal with a simple side salad tossed in a vinaigrette, some roasted vegetables (think asparagus or bell peppers), or even a slice of warm, crusty bread if you aren’t counting carbs. These sides bring color and balance to your plate.
Creative Ways to Present
Feeling fancy? Scoop individual portions into mini ramekins for personal-sized casseroles, or serve spoonfuls inside grilled bell pepper halves for a colorful, edible bowl. You can even roll leftovers in a low-carb tortilla for an easy next-day wrap packed with BBQ Chicken Cauliflower Rice Casserole Recipe magic!
Make Ahead and Storage
Storing Leftovers
Leftovers will keep you happy for days! Store your casserole in an airtight container in the fridge for up to four days. The flavors will only deepen with time, making those weekday lunches something to look forward to. Just be sure to let the dish cool completely before sealing it up to avoid unwanted moisture.
Freezing
Want to save some for a busy night? Simply let the baked casserole cool, wrap tightly in foil, and store in a freezer-safe container for up to three months. Thaw overnight in the refrigerator before reheating for the best texture.
Reheating
Pop individual portions into the microwave for a couple of minutes, or reheat larger amounts in a 350°F oven until warmed through. If the casserole looks a little dry, add a splash of extra barbecue sauce or a spoonful of Greek yogurt to revive its creamy texture.
