How to Make Healthier Broccoli Chicken Casserole Recipe
Step 1: Prep Your Baking Dish and Preheat
Begin by preheating your oven to 375°F (190°C) to set the stage for perfectly baked goodness. Lightly grease a 9×13-inch baking dish with cooking spray, ensuring effortless serving and cleanup later.
Step 2: Sauté Aromatics
In a large skillet over medium heat, warm your olive oil. Sauté the chopped onion until soft and slightly translucent, about 4–5 minutes. Add the minced garlic and let it cook for just a minute longer, filling your kitchen with a mouthwatering aroma.
Step 3: Mix Up the Casserole Base
Grab a roomy mixing bowl and add the cooked chicken, broccoli, your choice of brown rice or quinoa, the sautéed onion and garlic, Greek yogurt, chicken broth, mozzarella, Parmesan, salt, pepper, thyme, and onion powder. Stir until everything is luscious and well combined—this is the foundation of your Healthier Broccoli Chicken Casserole Recipe.
Step 4: Assemble and Top
Pour that creamy, colorful mixture into your prepared baking dish. Smooth it out evenly so every scoop will be just right. If you like a little extra crunch, sprinkle the top with whole wheat breadcrumbs and mist lightly with cooking spray to encourage a golden, crispy finish.
Step 5: Bake to Bubbly Perfection
Slide your casserole into the preheated oven and bake for 25–30 minutes. When it’s hot, bubbling, and golden on top, you’ll know it’s ready. Let it rest for about 5 minutes before serving so everything sets just enough for tidy slices and second helpings.
How to Serve Healthier Broccoli Chicken Casserole Recipe

Garnishes
Add a flourish with a sprinkle of extra Parmesan or a handful of fresh herbs like chopped parsley or chives right before serving. These little touches not only look lovely but also enliven every bite with a fresh burst of color and flavor.
Side Dishes
This casserole is a meal in itself, but it pairs wonderfully with a crisp green salad dressed in a tangy vinaigrette or some roasted carrots or asparagus for extra veggies. If you’re in the mood for something cozy, a roasted sweet potato rounds out the meal beautifully.
Creative Ways to Present
If you’re hosting or just want to shake things up, portion the Healthier Broccoli Chicken Casserole Recipe into individual ramekins before baking. Or, scatter a handful of cherry tomatoes on top before the casserole goes in the oven for an extra burst of color and juiciness.
