How to Make Healthier Broccoli Chicken Casserole: A Comforting and Nutritious Meal
Step 1: Prep Your Oven and Baking Dish
Begin by preheating your oven to 375°F. Lightly grease a 9×13-inch baking dish with a smidge of olive oil or nonstick spray, ensuring easy serving later and avoiding any sticky situations.
Step 2: Sauté the Onion and Garlic
Heat the olive oil in a skillet over medium heat. Add your chopped onion and sauté gently for about three to four minutes, just until soft and translucent. Stir in the minced garlic and cook for another 30 seconds, releasing that irresistible aroma that means something good is cooking.
Step 3: Combine the Main Ingredients
In a large mixing bowl, gather your cooked brown rice, chicken breast, lightly steamed broccoli, and the sautéed onion and garlic. Pour in the low-sodium chicken broth and creamy plain Greek yogurt, then sprinkle in the mozzarella cheese, Parmesan, salt, pepper, and dried thyme. Combine well—everything should look thoroughly mixed and evenly distributed, promising lots of flavor in every bite.
Step 4: Assemble in the Baking Dish
Spread your combined casserole mixture evenly into the prepared baking dish. If you’re feeling a little extra, sprinkle whole wheat breadcrumbs across the top for a delightful golden crunch after baking.
Step 5: Bake Until Golden and Bubbly
Pop your dish into the preheated oven and bake for 25 to 30 minutes. You’ll know it’s ready when the top is golden, the casserole is bubbly, and your kitchen smells like pure comfort. Allow it to cool slightly before serving—this helps everything set up for easy scooping.

Leftovers? Try stuffing them into a whole-wheat pita with crunchy salad greens for an easy lunch the next day.
Make Ahead and Storage
Storing Leftovers
Once the casserole has cooled, cover tightly or transfer to airtight containers. It will stay fresh in the fridge for up to four days, making it ideal for meal prep or quick dinners throughout the week.
Freezing
This dish freezes beautifully! Assemble the casserole up to the baking step, then cover well and freeze for up to three months. Thaw overnight in the fridge before baking as directed, adding an extra 10 minutes or so if baking from cold.
Reheating
For best results, reheat individual portions in the microwave, or cover the whole casserole with foil and warm in a 350°F oven until hot throughout. Add a splash of chicken broth if needed to revive moisture and keep that creamy texture.
FAQs
Can I use rotisserie chicken in Healthier Broccoli Chicken Casserole: A Comforting and Nutritious Meal?
Absolutely! Rotisserie chicken is a fantastic time-saver and adds even more flavor. Just remove the skin, shred or chop the meat, and use it in place of cooked chicken breast.
