- Avocado oil (2 tablespoons): Perfect for roasting broccoli, enhancing flavor without overpowering.
- Cooked chicken, cubed (3 cups): Lean protein that makes this casserole filling and satisfying.
- Shredded cheese (2 cups, divided): Brings gooey, melty comfort; use regular or vegan cheese according to your preference.
- Creamy cashew butter (1/2 cup): The secret to a luscious, dairy-free sauce with a subtle nutty undertone.
- Unsweetened plain cashew milk (3/4 cup): Keeps the sauce smooth and creamy without added sugars.
- Chicken or vegetable broth (1 cup): Adds depth and moistness, balancing out the cashew sauce.
- Almond flour (1/4 cup): Helps thicken the sauce naturally while keeping it gluten-free.
- Garlic powder (1/2 teaspoon): Infuses a gentle garlicky warmth to the sauce.

- Dried parsley (1/2 teaspoon): Introduces a touch of herbal brightness.
- Salt and pepper (to taste): Essential for seasoning every component to perfection.
How to Make Healthy Chicken Broccoli Pasta Casserole Recipe
Step 1: Preheat and Prep Your Oven and Pasta Water
Start strong by preheating your oven to 400 degrees F (200 degrees C). This ensures your broccoli roasts perfectly, developing those lovely slightly crisp edges. Simultaneously, bring a large pot of salted water to a rolling boil — you’ll be cooking the pasta right after.
Step 2: Roast the Broccoli for Maximum Flavor
Place the broccoli florets in a generously sized 9×13 inch casserole dish. Drizzle with avocado oil and sprinkle with salt and pepper to enhance their natural flavor. Roasting the broccoli concentrates its sweetness and adds a subtle char that pairs beautifully with the creamy sauce later.
Step 3: Cook the Pasta Just Right
While the broccoli roasts for 15 minutes, cook your whole wheat rotini according to the package directions. It’s best to pull it out al dente because it will continue cooking once baked in the casserole. Drain well and set aside to prevent sogginess.
Step 4: Whisk Together the Creamy Cashew Sauce
Now for the magic. In a bowl, whisk the cashew butter, plain cashew milk, broth, almond flour, garlic powder, paprika, dried parsley, and a pinch of salt and pepper until completely smooth. This sauce is rich and velvety, bringing all the components together with indulgent, dairy-free creaminess.
Step 5: Combine and Assemble Your Casserole
To the roasting dish with broccoli, add the cooked pasta, cubed chicken, one cup of shredded cheese, and the luscious cashew sauce. Stir thoroughly until everything is evenly coated and beautifully mixed. Sprinkle the remaining cheese on top for that irresistible melty finish.
Step 6: Bake to Gooey, Golden Perfection
Pop the casserole into your preheated oven for 10 to 15 minutes, or until the cheese is melted, bubbly, and sporting just a hint of golden brown on top. This final bake melds all the flavors, thickens the sauce further, and delivers cozy comfort straight from the oven.
Step 7: Let it Cool and Serve
Once out of the oven, give your casserole a few minutes to cool. This resting time helps it set slightly so you can serve clean, delicious slices that hold their shape and maximize every creamy, cheesy bite.
How to Serve Healthy Chicken Broccoli Pasta Casserole Recipe
Garnishes
A sprinkle of freshly chopped parsley or a few grinds of black pepper can add a fresh, vibrant pop that brightens the rich flavors of this casserole. For an extra touch, a little lemon zest grated on top can bring unexpected zing to every forkful.
Side Dishes
This casserole is a complete meal on its own, but if you want to round it out, a crisp garden salad with a light vinaigrette or a side of roasted carrots makes perfect companions. Alternatively, a crusty whole grain bread helps soak up any extra sauce leftover on the plate.
Creative Ways to Present
Serve this dish family-style straight from the casserole dish for warm, cozy gatherings. For a special occasion, consider individual ramekins for perfectly portioned, elegantly plated presentations. You can even layer it in a clear glass dish to show off those colorful broccoli florets and cheeses through the sides!
Make Ahead and Storage
Storing Leftovers
Once cooled completely, store leftovers in airtight containers in the refrigerator for up to 4 days. This casserole reheats wonderfully while preserving the creamy, rich texture and delightful flavors.
Freezing
For longer storage, freeze your Healthy Chicken Broccoli Pasta Casserole Recipe before baking, wrapped tightly with foil or in a freezer-safe dish. It will keep well for up to 3 months and can be baked straight from frozen with a bit of extra time added.
Reheating
Reheat individual servings in the microwave until warmed through or place the whole dish in a 350-degree F oven, covered, for about 20 minutes. If frozen, allow to thaw overnight in the fridge before reheating for best results.
FAQs
Can I use a different type of pasta for this casserole?
Absolutely! While whole wheat rotini adds a nice wholesome texture, penne, fusilli, or even gluten-free pasta alternatives will work beautifully and absorb the sauce wonderfully.
Is the cashew sauce dairy-free and vegan-friendly?
Yes, the sauce is naturally dairy-free thanks to the cashew butter and plant milk, making it vegan-friendly if you select vegan cheese options instead of traditional shredded cheese.
How do I cook chicken for this recipe?
You can use leftover cooked chicken, rotisserie chicken, or quickly sauté or bake chicken breasts or thighs and cube them. Just ensure the chicken is fully cooked before adding it to the casserole.
Can I add other vegetables to this casserole?
Definitely! Feel free to mix in vegetables like mushrooms, bell peppers, or spinach to customize and boost the nutrition of your casserole even more.
What can I substitute if I don’t have cashew butter?
If you don’t have cashew butter, almond butter or sunflower seed butter can be good substitutes, though they will slightly change the flavor profile. You might also try a simple vegan béchamel made with plant milk and flour if needed.
