How to Make This Skinny Chicken and Rice Casserole

Prepping Your Ingredients
Start by cooking your brown rice according to package directions if you’re not using pre-cooked rice. This step ensures the rice will bake perfectly and absorb all those delicious flavors. Meanwhile, sauté diced onion and minced garlic in a little olive oil or cooking spray. This simple step really lifts the flavor and creates a fragrant base for the casserole.

Mixing It All Together
In a large mixing bowl, combine the cooked rice, shredded chicken, sautéed onions and garlic, chopped broccoli (or your choice of veggies), Greek yogurt, low-sodium chicken broth, and shredded reduced-fat cheese. Season the mixture generously with salt, pepper, garlic powder, onion powder, smoked paprika, and if you like a little kick, a pinch of red pepper flakes. Stir until everything is well incorporated. The creamy yogurt blends with the broth and cheese to create a luscious sauce that keeps the casserole moist and satisfying.

Assembling and Baking
Grease a 9×13-inch baking dish lightly with cooking spray. Pour in your mixture and spread it out evenly. If you want that extra crunch on top, sprinkle whole wheat breadcrumbs over the casserole. Cover the dish with foil to keep it moist and bake in a preheated oven at 375°F (190°C) for 20 minutes. Then, remove the foil and bake uncovered for another 10 minutes until the top is golden and bubbly. Let it rest for about 5 minutes before serving so the flavors meld beautifully.

Tips and Tricks for the Best Casserole

• Use skinless chicken breast for the leanest option or thighs for juicier meat. Both work wonderfully.
• Don’t skip the sautéing step for onions and garlic — it adds a subtle sweetness and aroma that makes this dish extra special.
• For creamier casseroles, add ¼ cup of low-fat cream cheese or stir in a little light sour cream instead of yogurt.
• Feel free to swap brown rice for cooked quinoa for an added protein boost or cauliflower rice if you’re watching carbs.
• When using frozen vegetables, thaw and drain them well to avoid excess water making the casserole watery.
• Cover with foil during baking to prevent drying out, especially if your chicken is on the lean side.
• If you want a spicy twist, toss in diced jalapeños or sprinkle red pepper flakes into the mix.

Variations to Make This Dish Your Own

This casserole is a fantastic base for experimentation:

• Dairy-Free: Use coconut or almond-based yogurt and dairy-free cheese alternatives.
• Veggie-Packed: Mushrooms, zucchini, spinach, peas, or bell peppers all work great for extra nutrients and color.
• Cheese Swaps: Try Swiss, Monterey Jack, or even Parmesan for different flavor profiles.
• Slow Cooker Version: Combine everything raw with extra broth and cook on low for 4–6 hours for an effortless, hands-off meal.

Storage and Reheating

Leftovers taste just as good the next day! Store your casserole in an airtight container in the fridge for up to 4 days. For longer storage, freeze in a sealed container for up to 3 months. To reheat, warm it in the oven at 350°F (175°C) for about 15 minutes or microwave in short bursts until hot and bubbly.

Serving Suggestions

This casserole is a complete meal on its own but pairs beautifully with a fresh green salad, steamed veggies, or even some crusty whole-grain bread. A squeeze of lemon juice or a sprinkle of fresh herbs like parsley or chives on top just before serving can brighten all the flavors.
