- 2 cups shredded cheese (regular or vegan), divided: Use your favorite cheese for melty, flavorful goodness.
- 1/2 cup creamy cashew butter: This is the base for the luscious sauce, adding creaminess and a subtle nutty taste.
- 3/4 cup unsweetened plain cashew or almond milk: Keeps the sauce smooth without extra sweetness.
- 1 cup chicken or vegetable broth: Adds depth and moisture to the sauce.
- 1/4 cup almond flour: Helps thicken the sauce naturally without gluten.
- 1/2 teaspoon garlic powder: Brings a savory warmth to the dish.

- Salt and pepper, to taste: Essential for balancing and enhancing all the flavors.
How to Make Healthy Chicken Broccoli Pasta Casserole Recipe
Step 1: Preheat and Prep
Start by warming your oven to 400 degrees Fahrenheit (200 degrees Celsius). Meanwhile, fill a pot with water and bring it to a boil for cooking the pasta. It’s important to get these started early so everything cooks smoothly and on time for the perfect casserole assembly.
Step 2: Roast the Broccoli
Place the broccoli florets evenly in a 9×13 inch casserole dish, drizzle them with avocado oil, and season with salt and pepper. Roasting the broccoli at high heat for about 15 minutes helps develop their natural sweetness and gives a slight crisp-tender bite that contrasts beautifully with the creamy casserole sauce.
Step 3: Cook the Pasta
While the broccoli roasts, cook your whole wheat rotini pasta according to the package instructions until al dente. Drain the pasta well and set it aside to prevent sogginess later. Properly cooked pasta is essential to balance the textures in the final dish.
Step 4: Make the Cashew Sauce
In a mixing bowl, whisk together the creamy cashew butter, unsweetened cashew or almond milk, chicken or vegetable broth, almond flour, garlic powder, paprika, dried parsley, salt, and pepper until you achieve a smooth, silky sauce. This sauce is the magic that binds everything with a velvety, dairy-free creaminess that feels indulgent yet healthy.
Step 5: Assemble and Bake
In the casserole dish with the roasted broccoli, combine the cooked pasta, cubed chicken, 1 cup of the shredded cheese, and the cashew sauce. Mix everything gently but thoroughly until the pasta and broccoli are evenly coated in that luscious sauce. Sprinkle the remaining cheese over the top for a golden, bubbly finish. Bake the casserole in the oven for 10 to 15 minutes, or until the cheese is melted and starting to brown.
Step 6: Serve
Once the casserole is out of the oven, set it aside to cool for a few minutes. This rest time allows the casserole to set slightly, making it easier to serve and even more enjoyable as the flavors meld together beautifully.
How to Serve Healthy Chicken Broccoli Pasta Casserole Recipe

Garnishes
To elevate your plate, sprinkle freshly chopped herbs like parsley or chives over the top. A light dusting of nutritional yeast can add a cheesy, nutty flavor if you’re leaning vegan. These little touches brighten up the flavors and add that inviting ‘finished’ look to your dish.
Side Dishes
This casserole pairs wonderfully with light sides such as a crisp green salad tossed in lemon vinaigrette or some roasted cherry tomatoes. The fresh acidity cuts through the creaminess of the casserole, balancing the meal perfectly.
Creative Ways to Present
Consider serving this Healthy Chicken Broccoli Pasta Casserole Recipe in individual ramekins for a charming dinner party presentation. Alternatively, top each scoop with a dollop of dairy-free sour cream or a spoonful of your favorite salsa for a fun, customizable twist.
Make Ahead and Storage
Storing Leftovers
This casserole keeps beautifully in an airtight container in the refrigerator for up to 4 days. The flavors meld even more after a day, making your leftovers just as wonderful as the first serving.
Freezing
If you want to prep in advance, this casserole freezes well for up to 3 months. Portion it into freezer-safe containers before baking or freeze the fully baked casserole wrapped tightly in foil and plastic wrap for easy meals down the road.
Reheating
Reheat your leftovers in the oven at 350 degrees Fahrenheit until warmed through and bubbly again, about 15-20 minutes. You can also microwave individual servings covered loosely to avoid drying out the pasta and broccoli.
FAQs
Can I use a different type of pasta in this Healthy Chicken Broccoli Pasta Casserole Recipe?
Absolutely! While whole wheat rotini adds fiber and texture, you can substitute with penne, fusilli, or even gluten-free pasta varieties depending on your preferences or dietary needs.
Is the cashew sauce suitable for those with nut allergies?
The cashew sauce is a key part of the recipe’s creaminess, but if you have a nut allergy, you can try substituting it with a dairy-free cream alternative like oat-based cream or a béchamel made from seeds like sunflower or pumpkin.
Can I prepare this dish without chicken?
Yes! This casserole is very versatile and can be made vegetarian by leaving out the chicken or swapping in plant-based protein like chickpeas or tofu for a delicious twist.
How can I make this recipe vegan?
To make this Healthy Chicken Broccoli Pasta Casserole Recipe vegan, simply use vegan cheese and ensure your broth is vegetable-based. The cashew sauce is already plant-based and perfect for vegan diets.
What’s the best way to make sure the broccoli doesn’t get soggy?
Roasting the broccoli separately with a bit of oil before mixing it into the casserole helps maintain its texture. Avoid overcooking the pasta too, so the overall dish stays firm and fresh.
