Instead of traditional rice, this recipe uses cauliflower rice to keep it light, low in carbs, and nutrient-packed. Each bite gives you tender chicken coated in tangy BBQ sauce, mixed with sautéed onions and garlic, and finished with a golden layer of melted cheddar cheese on top. It’s the kind of meal that feels indulgent but is secretly wholesome!

Ingredients in BBQ Chicken Cauliflower Rice Casserole

This dish is made with simple, everyday ingredients that come together beautifully. You’ll only need 11 ingredients total — three of which are just seasonings!

• Onion: Half a yellow onion adds just the right amount of sweetness and depth.
• Garlic: Three cloves, minced, to boost flavor.
• BBQ sauce: ¾ cup of your favorite BBQ sauce ties everything together with smoky sweetness.

• Seasonings: A mix of salt, pepper, and chili powder enhances all the savory flavors.
