Getting the perfect balance of flavor and texture in this dish hinges on a handful of simple, quality ingredients. Each one plays a key role—from the tender chicken providing protein to the cauliflower rice offering a wholesome, grain-free base—and together they create a casserole that’s both nutritious and utterly delicious.

2 large boneless, skinless chicken breasts: Cooked and chopped, these bring hearty protein and a meaty texture to the dish.
1 (8 oz) bag frozen cauliflower rice: Defrosted, it’s a fantastic low-carb substitute that soaks up flavors beautifully.
2 tablespoons olive oil: Adds richness and is perfect for sautéing the aromatics to release their full flavor.
½ yellow onion, diced: Gives sweetness and a satisfying bite once softened.
3 cloves garlic, minced: Provides a punch of savory depth to complement the BBQ sauce.
¾ cup BBQ sauce: The star ingredient that ties everything together with its smoky and tangy essence.
2 large eggs: These help bind the casserole and give it a lovely, set structure after baking.
½ teaspoon salt: Essential for enhancing all the flavors in the dish.
½ teaspoon black pepper: Adds a bit of warmth and subtle heat.
¼ teaspoon chili powder: Just enough spice to elevate the BBQ flavor without overwhelming.
¾ cup shredded cheddar cheese: Melts on top for a golden, gooey crust that’s difficult to resist.

How to Make BBQ Chicken Cauliflower Rice Casserole Recipe

Step 1: Preheat and Prep

Start by heating your oven to 400°F (200°C). This ensures it’s perfectly hot when your casserole is ready to go in. Don’t forget to grease an 8×8 inch baking dish with nonstick spray so your casserole doesn’t stick and you can serve it effortlessly.

Step 2: Combine the Main Ingredients

In a large mixing bowl, toss together the chopped cooked chicken and the defrosted cauliflower rice. This combination forms the hearty foundation of your casserole and sets the stage for all the delicious flavors to come.

Step 3: Sauté Aromatics

Heat olive oil in a skillet over medium heat and add the diced yellow onion. Cook it until it’s tender and translucent, bringing out its natural sweetness. Then, stir in the minced garlic, cooking for just about a minute until fragrant—this step infuses your dish with those signature savory notes.

Step 4: Mix and Season

Pour the sautéed onion and garlic into the bowl with the chicken and cauliflower rice. Add in the BBQ sauce, eggs, salt, black pepper, and chili powder. Stir everything thoroughly to ensure the sauce evenly coats all the components, and the eggs are well distributed to help bind the casserole during baking.

Step 5: Bake with Cheese

Transfer the mixture into your prepared baking dish, smoothing it out for even cooking. Sprinkle the shredded cheddar cheese evenly over the top. Slide the dish into your preheated oven and bake for about 45 minutes until the casserole is set and the cheese has melted into a golden brown, bubbly crust.

Step 6: Cool and Serve

Once out of the oven, give your BBQ Chicken Cauliflower Rice Casserole Recipe about 5 minutes to cool and set. This helps ensure clean slicing and that the flavors settle beautifully before serving.

How to Serve BBQ Chicken Cauliflower Rice Casserole Recipe

Garnishes

A sprinkle of freshly chopped parsley or sliced green onions adds a vibrant pop of color and freshness that balances the rich, smoky flavors of the casserole. A dollop of sour cream or a drizzle of extra BBQ sauce on top can also take the serving presentation to the next level.

Side Dishes

This casserole is a meal on its own, but if you want to round things out, consider a crisp green salad with a light vinaigrette or some steamed seasonal veggies. A side of roasted sweet potatoes or even cornbread works beautifully to complement the BBQ theme and satisfy bigger appetites.

Creative Ways to Present

If you’re serving this BBQ Chicken Cauliflower Rice Casserole Recipe for a gathering, try scooping it into individual ramekins or large muffin tins for cute individual portions. Adding a sprinkle of extra cheese and broiling briefly before serving will add an irresistible golden crust that your guests will love.

Make Ahead and Storage

Storing Leftovers

After enjoying your casserole, you can store any leftovers in an airtight container in the refrigerator for up to 3 days. This makes for a quick and satisfying lunch or dinner option during a busy week.

Freezing

If you want to prepare ahead, this BBQ Chicken Cauliflower Rice Casserole Recipe freezes exceptionally well. Freeze the unbaked casserole (tightly covered) for up to 2 months. When ready to enjoy, simply thaw overnight in the fridge and bake as instructed.

Reheating

Reheat leftover casserole in the oven at 350°F (175°C) for about 15-20 minutes until warmed through and the cheese is melty once again. Alternatively, a quick 2-3 minute zap in the microwave works well for a fast meal without losing too much texture.

FAQs

Can I use fresh cauliflower instead of frozen cauliflower rice?

Absolutely! If you prefer fresh cauliflower, simply pulse it in a food processor until it reaches a rice-like consistency. Sauté it a bit before mixing to remove excess moisture and keep your casserole from becoming watery.

Is this recipe suitable for meal prepping?

Yes, it’s fantastic for meal prep. It stores well in the fridge, freezes nicely, and reheats without losing its flavor or texture, making it a convenient make-ahead option.

Can I substitute the chicken with another protein?

Definitely. Shredded cooked turkey or even cooked pulled pork can be used to switch things up while keeping the BBQ flavor front and center.

What type of BBQ sauce is best to use?

Choose a tangy yet not overly sweet BBQ sauce for the best balance. Homemade or store-bought sauces that feature a good smoky depth will elevate the casserole perfectly.

Can I make this recipe dairy-free?

Yes! Simply omit the cheddar cheese or use a dairy-free cheese alternative. The casserole will still be flavorful and satisfying thanks to the BBQ sauce and aromatics.
