How to Make Healthy Chicken Broccoli Pasta Casserole Recipe
Step 1: Prep and Preheat
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil spray to make sure nothing sticks and that golden brown finish slides seamlessly off the pan. This step ensures the Healthy Chicken Broccoli Pasta Casserole Recipe is easy to serve (and easy to clean up later!).
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil and add your whole wheat pasta. Cook until it’s just al dente—remember, it’ll keep cooking in the oven, so don’t overdo it now. Drain and set aside. The slightly firm texture keeps the final dish from getting mushy.
Step 3: Sauté the Aromatics
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Toss in your chopped onion and sauté for 3–4 minutes until soft and translucent. Add the minced garlic and stir for another minute, releasing incredible aroma that will infuse your casserole with warmth from the very first bite.
Step 4: Prepare the Creamy Sauce
Sprinkle the whole wheat flour over the onion mixture and cook while stirring for about a minute. This helps develop flavor and ensures there won’t be any raw flour taste. Gradually whisk in the low-fat milk, keeping things smooth. Bring to a simmer and stir for 3–4 minutes as it thickens into a glossy, creamy sauce that’s secretly light. Off the heat, blend in the Greek yogurt, Dijon mustard, Italian seasoning, salt, and black pepper for flavor that sings.
Step 5: Mix and Assemble
In a big mixing bowl, combine the cooked pasta, chicken, and broccoli with your just-made sauce. Toss everything gently but thoroughly so every piece of pasta and broccoli is coated in creamy goodness. Pour the mixture into your prepared baking dish, smoothing out the top with a spatula.
Step 6: Add Cheese & Toppings
Sprinkle the mozzarella and Parmesan cheeses evenly over the surface. If you love a crisp topping, add the whole wheat breadcrumbs and give a light mist of olive oil spray. This combo creates a bubbly, melty, and lightly golden crust when baked.
Step 7: Bake and Serve
Slide your assembled casserole into the oven and bake for 20–25 minutes, or until everything is hot, bubbly, and fabulously golden on top. Let the Healthy Chicken Broccoli Pasta Casserole Recipe sit for a few minutes before serving—this helps the cheesy layers set and makes cutting into squares much easier.
How to Serve Healthy Chicken Broccoli Pasta Casserole Recipe

Garnishes
A simple sprinkle of fresh chopped parsley or basil on top just before serving brings a burst of color and a fresh herby kick. If you’re feeling extra, a dash more Parmesan or a crack of black pepper can never go wrong! This Healthy Chicken Broccoli Pasta Casserole Recipe loves a little extra attention.
Side Dishes
Since this casserole is a balanced meal all on its own, keep the sides light! A crisp mixed greens salad with a splash of vinaigrette, or some roasted veggies make wonderful companions. Warm, crusty bread is always a crowd-pleaser if you want to soak up some of that creamy sauce.
Creative Ways to Present
If you want to impress for a gathering, scoop the casserole into individual ramekins for single servings. Or, spoon it onto a bed of fresh spinach to add more greens and give it a bistro-style vibe. The Healthy Chicken Broccoli Pasta Casserole Recipe also holds up beautifully as a packed lunch the next day—try it cold as a pasta salad!
Make Ahead and Storage
Storing Leftovers
Leftover Healthy Chicken Broccoli Pasta Casserole Recipe stores well in the fridge for up to 4 days. Be sure to cover the baking dish tightly with foil or transfer portions to airtight containers. The flavors meld as it sits, so you might even find you love it more the next day!
Freezing
This casserole is a freezer-friendly superstar. Once cooled, wrap individual portions or the whole baking dish tightly with plastic wrap then foil. It’ll last up to 3 months. For the crispiest topping, wait to add breadcrumbs until after you reheat.
Reheating
Reheat in a 350°F oven, covered with foil, until warmed through—usually about 20 minutes for a full pan, less for single servings. For quick meals, use the microwave; just sprinkle a little water over the top to keep things from drying out. The Healthy Chicken Broccoli Pasta Casserole Recipe always bounces back to creamy, cozy perfection!
