How to Make Healthier Broccoli Chicken Casserole
Step 1: Prep the Oven and Pan
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with a spritz of nonstick spray or a bit of olive oil to make cleanup a breeze and prevent sticking. Having the oven and dish ready means you can move swiftly from stovetop to baking with zero fuss.
Step 2: Make the Creamy Sauce
Heat the olive oil in a large skillet set over medium heat. Add the diced onion and sauté for 3–4 minutes, stirring often until it begins to soften and turn translucent. Toss in the minced garlic and cook for just about a minute, releasing its irresistible aroma without letting it burn. Pour in the chicken broth, then bring it to a gentle simmer. Reduce the heat and slowly whisk in the Greek yogurt and milk until the sauce looks smooth and creamy. Add the shredded cheddar, salt, black pepper, and paprika — stir until the cheese is melted and everything blends into a velvety sauce that you’ll want to sneak a spoonful of right away.
Step 3: Assemble the Casserole
Grab a big mixing bowl and combine the cooked chicken, lightly steamed broccoli florets, and cooked brown rice or quinoa. Pour in your freshly made cheese sauce and mix until each piece is evenly coated in creamy goodness. This step is where all those simple ingredients come together as a team, each bite promising a burst of flavor, color, and wonderful texture.
Step 4: Fill and Top the Baking Dish
Spoon your mixture into the prepared baking dish, spreading it out with a spatula until it’s level. If you’re going for extra flavor (and a pretty golden crust), sprinkle grated Parmesan evenly over the top. The cheese will bake into a deliciously crisp layer that makes the finished casserole even more inviting.
Step 5: Bake and Rest
Slide the casserole into the preheated oven and bake for 20–25 minutes, or until it’s heated through and just lightly golden on top. When you remove it, let it rest for about 5 minutes — this helps everything set up just right, so you get neat, delicious squares.
How to Serve Healthier Broccoli Chicken Casserole

Garnishes
A sprinkle of fresh parsley adds a burst of color and a touch of herbal freshness that brightens the whole casserole. For a tangy twist, add a few lemon zest curls. If you love a little crunch, try a scattering of toasted nuts or seeds, or a sprinkle of whole wheat breadcrumbs just before baking for an extra-textured top.
Side Dishes
This casserole pairs beautifully with a crisp green salad dressed in a light vinaigrette, roasted carrots, or even some sliced tomatoes in the summer. Try serving with a hunk of warm whole-grain bread to soak up any creamy sauce left behind. The idea is to keep sides light and vibrant — after all, the Healthier Broccoli Chicken Casserole is filling enough to be the star of your dinner table.
Creative Ways to Present
For easy entertaining, spoon the casserole into individual ramekins for personal servings. Or, for a playful twist, serve it in big lettuce cups for a fork-free option at a party. Leftovers are just as enticing in a wrap for a quick lunch, or even scooped onto a baked sweet potato for a hearty, nutritious meal that feels totally new.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover Healthier Broccoli Chicken Casserole tightly and refrigerate for up to 4 days. Portioning out individual servings in airtight containers makes enjoying quick lunches or dinners absolutely effortless.
Freezing
This casserole is a total hero when it comes to meal prep. Cool it completely, then wrap portions (or the whole dish) securely in plastic wrap and foil before freezing. It will keep well for up to 2 months. For extra convenience, freeze in single-serve portions for fast, balanced meals any time.
Reheating
To reheat, simply microwave individual servings for 1–2 minutes until steaming hot, or warm a larger portion in a covered baking dish at 350°F (175°C) for 15–20 minutes. If frozen, it’s best to thaw overnight in the fridge before reheating for even results.
FAQs
Can I use rotisserie chicken for this casserole?
Absolutely! Rotisserie chicken is a great shortcut and adds an extra layer of flavor. Just shred or chop the meat and use it in place of cooked chicken breast for an even quicker prep.

Yes! Simply use an unsweetened non-dairy milk and swap in a dairy-free yogurt and cheese alternative. The result will still be creamy, comforting, and totally satisfying.
What other veggies pair well with this Healthier Broccoli Chicken Casserole?

How can I make the top even crispier?
For an irresistible crunchy topping, mix a handful of whole wheat breadcrumbs with a drizzle of olive oil and sprinkle them over the casserole before baking. A quick broil at the very end can also give you that golden, crispy finish!
